[0002] In the real world, due to the eruption of solar storms, planets will be hit by storms, but due to the protection of the planet's own magnetic field, there is a safe zone in the outer layer of the planet's atmosphere and in the shade of the planet. This safe zone can avoid the impact of solar storms.

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the real world, due to the outbreak of solar storms, planets will be hit by storms, but due to the protection of the planet's own magnetic field, there is a safe zone in the outer layer of the planet's atmosphere and in the shade of the planet. It can also be understood that due to the blocking of solar storms by the planet's magnetic field, there is a certain safe zone on the head and back of the planet. This safe zone can avoid the impact of solar storms.

[0045] In relevant game scenes, the safe zone of the planet can be used for the virtual character controlled by the player to stay and avoid the impact of the solar storm. Specifically, in the game scene, by placing several solid color fan-shaped models (such as Figure 1 The shaded area shown in the figure is used to simulate the magnetic field effect of a planet after being impacted by a solar storm, and the magnetic field effect is used to indicate the safe zone of the planet, such as Figure 1 The figure shows the magnetic field effect of a planet after being impacted by a solar storm, simulated in the prior art. Figure 1 The two circles in the figure represent two planets. However, this simulation method does not visualize the planetary magnetic field, and the magnetic field effect does not conform to the physical magnetic field in the real world. In the real physical magnetic field, the magnetic field between the planet and the star should be a protruding ellipse. Figure 1 The magnetic fields of the two planets facing the stars are concave; at the same time, simulating the safe zone only with a solid-color fan-shaped area can easily cause misunderstanding among players, making them unclear about the significance of the safe zone. This weakens the expression of the game's worldview and easily reduces the player's gaming experience.

[0046] Based on the above problems, the embodiments of the present invention provide a method, device and electronic device for simulating the magnetic field of a planet in a virtual scene. The technology can be applied to the simulation scene of the magnetic field effect of a planet in a virtual scene. In order to facilitate the understanding of the embodiments of the present invention, the simulation method of the magnetic field of a planet in a virtual scene disclosed in the embodiments of the present invention is first described in detail. Figure 2 As shown, the method comprises the following specific steps:

[0047] Step S202, obtaining the size information of the target planet and the relative direction between the virtual storm and the target planet.

[0048] The size information may include the radius, diameter or other size parameters of the target planet. The virtual storm may be a solar storm or a storm caused by other stars. Under the action of the virtual storm, the planet may generate a magnetic field safety zone according to its original magnetic field. In a specific implementation, the size information of the target planet may be input by a user through an electronic device, and the relative direction of the virtual storm and the target planet may be determined according to the position of the target planet.

[0049] Step S204, determining the magnetic field display parameters of the target planet based on the size information of the target planet; wherein the magnetic field display parameters include: size parameters of a specified ellipse and / or tangent parameters of a specified ellipse for generating the magnetic field region of the target planet.

[0050] Generally, the larger the size of the target planet, the more ellipses will be specified in the magnetic field display parameters of the target planet, and the size of the specified ellipses will be relatively larger. At the same time, the number of tangents of the specified ellipse will also be more, and the inclination angle of the tangent to the ellipse will be larger. Among them, the size parameters of the specified ellipse include the size of the minor axis radius and the major axis radius of the ellipse, and the tangent parameters of the specified ellipse include the coordinates of the tangent point position of the ellipse.

[0051] In a specific implementation, the magnetic field display parameters of the target planet may include only the size parameters of the specified ellipse, may include both the tangent parameters of the specified ellipse, or may include only the size parameters of the specified ellipse and the tangent parameters of the specified ellipse. Specifically, according to the size parameters of the specified ellipse, an ellipse may be obtained, which may represent the magnetic field lines of the magnetic field region and may also characterize the size of the magnetic field region; according to the tangent parameters of the specified ellipse, the tangent of the ellipse may be obtained, which may be used to characterize the magnetic field lines of the magnetic field region.

[0052] Step S206, generating a magnetic field region of the target planet under the action of a virtual storm according to the magnetic field display parameters and the relative direction.

[0053] In specific implementation, based on the magnetic field display parameters, the first magnetic field area of ​​the target planet facing the direction of the virtual storm and the second magnetic field area generated by the target planet shielding the virtual storm can be generated. The first magnetic field area and the second magnetic field area here are both safe areas under the virtual storm. The first magnetic field area and the second magnetic field area are usually composed of a specified ellipse and a tangent of the specified ellipse, so that the magnetic field area of ​​the target planet under the action of the virtual storm can be intuitively seen, and the magnetic field effect of the target planet can be visualized in the virtual scene, thereby improving the richness of the game screen; at the same time, the magnetic field effect is expressed through the ellipse and the tangent of the ellipse, which is consistent with the physical magnetic field effect in the real world.

[0054] The embodiment of the present invention provides a method for simulating the magnetic field of a planet in a virtual scene. First, the size information of the target planet and the relative direction between the virtual storm and the target planet are obtained; then, based on the size information of the target planet, the magnetic field display parameters of the target planet are determined, and the magnetic field display parameters include the size parameters of a specified ellipse and / or the tangent parameters of a specified ellipse for generating the magnetic field area of ​​the target planet; then, according to the magnetic field display parameters and the relative direction, the magnetic field area of ​​the target planet under the action of the virtual storm is generated. This method can automatically adapt to the size of the planet, obtain the magnetic field display parameters of the planet, and then generate a magnetic field area composed of an ellipse and the tangent of the ellipse according to the magnetic field display parameters, so that the magnetic field effect of the planet under the action of the virtual storm can be visualized; at the same time, the ellipse is used to characterize the magnetic field in accordance with the physical magnetic field line effect in the real world, so that the planetary magnetic field in the virtual scene can be simulated more realistically, and the player's gaming experience can be improved.

[0055] The embodiment of the present invention also provides another method for simulating the magnetic field of a planet in a virtual scene. The method is implemented on the basis of the above embodiment. The method focuses on describing the specific process of determining the magnetic field display parameters of the target planet based on the size information of the target planet (specifically implemented by the following step S304), and the specific process of generating the magnetic field area of ​​the target planet under the action of the virtual storm according to the magnetic field display parameters and the relative direction (specifically implemented by the following steps S306-S310); Figure 3 As shown, the method comprises the following specific steps:

[0056] Step S302, obtaining the size information of the target planet and the relative direction between the virtual storm and the target planet.

[0057] Step S304, searching for magnetic field display parameters that match the size information of the target planet from a preset database; wherein the magnetic field display parameters include: size parameters of a specified ellipse and tangent parameters of the specified ellipse for generating the magnetic field area of ​​the target planet; the magnetic field area of ​​the target planet includes: a first magnetic field area of ​​the target planet facing the direction of the virtual storm, and a second magnetic field area generated by the target planet shielding the virtual storm.

[0058] In the specific implementation, the preset database is pre-set by the R&D personnel, and the preset database stores multiple size parameters of the planet and the magnetic field display parameters corresponding to each size parameter. Specifically, the size parameter can be the radius of the planet, and the magnetic field display parameter can be parameters such as the magnetic field radius, opening width, and number of magnetic field lines, where the radius of the magnetic field corresponds to the size parameter of the specified ellipse, and the opening width corresponds to the tangent parameter of the specified ellipse. Generally, the larger the radius of the planet, the larger the magnetic field radius and opening width, and the more magnetic field lines there are.

[0059] Step S306: generating a first magnetic field region of the target planet facing the direction of the virtual storm based on the size parameters of the designated ellipse included in the magnetic field display parameters.

[0060] In the specific implementation, multiple ellipses with different eccentricities can be obtained according to the size parameters of the ellipse specified in the magnetic field display parameters. By combining multiple ellipses with different eccentricities, multiple magnetic field lines (also called magnetic flux lines) of the planet can be simulated, and then the first magnetic field area of ​​the target planet facing the direction of the virtual storm can be obtained.

[0061] In practical applications, the magnetic field display parameters further include the first number of magnetic field lines included in the first magnetic field region; the size parameters of the specified ellipse in the magnetic field display parameters include: the minor axis radius and the major axis radius of the specified ellipse corresponding to each magnetic field line in the magnetic field lines included in the first magnetic field region; based on this, the above step S306 can be implemented by the following steps 10-11:

[0062] Step 10: for each magnetic field line in the first magnetic field region, generate a current magnetic field line according to the minor axis radius and the major axis radius of the specified ellipse corresponding to the current magnetic field line.

[0063] The magnetic field display parameters include the first number of magnetic field lines set in the first magnetic field region, and the size of the minor axis radius and the major axis radius of the specified ellipse required to generate each magnetic field line. In specific implementation, each of the first number of magnetic field lines included in the first magnetic field region can be used as the current magnetic field line in turn, and then the current magnetic field line is generated through the following steps 20-22:

[0064] Step 20, obtain the minor axis radius and major axis radius of the specified ellipse corresponding to the current magnetic field line, construct a first ellipse with a major axis radius of a first value and a minor axis radius of a second value, and construct a second ellipse with a major axis radius of the first value and a minor axis radius of a third value.

[0065] When the planet is not affected by the virtual storm, the magnetic field lines of the planet are elliptical, but under the influence of the virtual storm, the ellipses corresponding to the magnetic field lines in the first magnetic field region of the planet will be compressed. The present invention uses two semi-ellipses with different minor axis radii to combine to reflect this compression phenomenon. Therefore, each magnetic field line in the first magnetic field region needs to be composed of two ellipses, so that the magnetic field display parameters include: two ellipses corresponding to each magnetic field line, and the size of the major axis radius and the minor axis radius corresponding to each ellipse.

[0066] Specifically, by obtaining the sizes of the major axis radius and the minor axis radius of the two ellipses corresponding to the current magnetic field lines from the magnetic field display parameters, the first ellipse and the second ellipse can be obtained, wherein the first ellipse and the second ellipse have the same major axis radius and different minor axis radii, which is beneficial for the subsequent splicing of the semi-ellipse of the first ellipse and the semi-ellipse of the second ellipse, and can reflect the compression phenomenon of the magnetic field lines.

[0067] Step 21, select the semi-ellipse of the first ellipse and the semi-ellipse of the second ellipse, and combine the semi-ellipse of the first ellipse and the semi-ellipse of the second ellipse into a closed combined ellipse.

[0068] In specific implementation, the Y axis (equivalent to the vertical axis) of the first ellipse and the second ellipse is used as the dividing line. The upper half of the first ellipse and the lower half of the second ellipse can be selected, or the lower half of the first ellipse and the upper half of the second ellipse can be selected. The specific determination is based on research and development needs. Then the selected half ellipse of the first ellipse and the half ellipse of the second ellipse are spliced ​​with the Y axis as the splicing line to obtain a closed combined ellipse. Figure 4 FIG. 1 is a schematic diagram of a combined ellipse provided by an embodiment of the present invention. Figure 4The upper half ellipse is the half ellipse of the first ellipse, and the lower half ellipse is the half ellipse of the second ellipse, wherein the major axis radius of the first ellipse and the second ellipse is a (equivalent to the above-mentioned first value), the minor axis radius of the first ellipse is b1 (equivalent to the above-mentioned second value), and the minor axis radius of the second ellipse is b2 (equivalent to the above-mentioned third value).

[0069] In practical applications, after selecting the semi-ellipse of the first ellipse and the semi-ellipse of the second ellipse, and combining the semi-ellipse of the first ellipse and the semi-ellipse of the second ellipse into a closed combined ellipse, it is also necessary to stroke the combined ellipse to obtain an edge contour with a specified width around the combined ellipse; then set the edge contour to a third color. The above-mentioned specified width can be set according to research and development requirements, for example, it can be set to 10cm or 5cm, etc., and the specific color of the above-mentioned third color can also be set according to research and development requirements. Figure 5 The figure shows a schematic diagram of a stroked combined ellipse provided in an embodiment of the present invention. The combined ellipse can be used to characterize the magnetic field lines. Stroke the combined ellipse can further distinguish the boundaries of each magnetic field line. After stroking the combined ellipse, the preliminary shape of the magnetic field line can be obtained.

[0070] In specific implementation, the stroke can be a combined ellipse that is repeatedly generated, except that the major axis radius is slightly enlarged to obtain a slightly larger ellipse, and finally the small ellipse is subtracted from the large ellipse to obtain the edge effect. Specifically, the specific process of stroking the combined ellipse to obtain an edge contour with a specified width around the combined ellipse includes: adding the first value to the first threshold to obtain a fourth value; adding the second value to the second threshold to obtain a fifth value; adding the third value to the third threshold to obtain a sixth value; constructing a third ellipse with a major axis radius of the fourth value and a minor axis radius of the fifth value, and constructing a fourth ellipse with a major axis radius of the fourth value and a minor axis radius of the sixth value; selecting the semi-ellipse of the third ellipse and the semi-ellipse of the fourth ellipse, and combining the semi-ellipse of the third ellipse and the semi-ellipse of the fourth ellipse into a closed combined ellipse; combining the semi-ellipse of the third ellipse and the semi-ellipse of the fourth ellipse into a closed combined ellipse, subtracting the combined ellipse formed by the semi-ellipse of the first ellipse and the semi-ellipse of the second ellipse, and obtaining the edge contour with a specified width corresponding to the combined ellipse formed by the semi-ellipse of the first ellipse and the semi-ellipse of the second ellipse.

[0071] The first threshold, the second threshold and the third threshold can be set according to research and development requirements. Generally, the larger the threshold is set, the thicker the stroke is.

[0072] Step 22, respectively setting the color and transparency inside and outside the combined ellipse, and determining the set combined ellipse as the current magnetic field line in the first magnetic field region.

[0073] In a specific implementation, the color inside the combined ellipse can be set to the first color, the color outside the combined ellipse can be set to the second color, and the transparency inside the combined ellipse can be set to a preset value; wherein the transparency inside the combined ellipse is used to indicate the magnetic field strength, and as the major axis radius of the combined ellipse increases, the value of the transparency setting inside the combined ellipse becomes smaller.

[0074] The first color, second color and preset value can be the default value set according to the research and development requirements, or can be the specific value input by the user according to the requirements. Specifically, the larger the radius of the major axis of the combined ellipse, that is, the larger the magnetic field radius of the magnetic field line, the smaller the value of the transparency setting in the combined ellipse. Generally, the smaller the value of the transparency setting, the more transparent it is, which can also be understood as the lighter the color here; at the same time, the smaller the value of the transparency setting, the smaller the magnetic field strength.

[0075] Step 11, combining the generated first number of magnetic field lines to obtain a first magnetic field region; wherein the magnetic field radius of the magnetic field lines in the first magnetic field region increases from inside to outside, and the magnetic field radius matches the major axis radius of the specified ellipse corresponding to the magnetic field line.

[0076] In a specific implementation, the location of the target planet is taken as the combination center, and in the relative direction between the target planet and the virtual storm, a first number of magnetic field lines are combined in order from the magnetic field radius of the magnetic field line to the largest to obtain a first magnetic field region. Figure 6 FIG. 1 is a schematic diagram of a first magnetic field region including three magnetic field lines. Figure 3 The location where the three magnetic field lines intersect is the center of the target planet.

[0077] Step S308, based on the size parameters of the designated ellipse and the tangent parameters of the designated ellipse included in the magnetic field display parameters, a second magnetic field region generated by the target planet blocking the virtual storm is generated.

[0078] In the specific implementation, according to the size and tangent parameters of the ellipse specified in the magnetic field display parameters, multiple ellipses with different eccentricities and tangents of some of the multiple ellipses can be obtained. Then, by combining the ellipses and tangents, multiple closed magnetic field lines and multiple open magnetic field lines of the planet can be simulated, and then the second magnetic field region generated by the target planet blocking the virtual storm can be obtained. The second magnetic field region can also be understood as the magnetic field region behind the target planet.

[0079] In practical applications, the second magnetic field region includes a near magnetic field region generated by the target planet blocking the virtual storm, and an infinite magnetic field region generated by the target planet blocking the virtual storm, wherein the near magnetic field region contains closed magnetic field lines, the shape of which can be a closed ellipse-like shape, and the infinite magnetic field region contains open magnetic field lines, which are open and composed of a semi-ellipse and a tangent. Based on this, the magnetic field display parameters also include: the second number of closed magnetic field lines contained in the near magnetic field region, and the third number of open magnetic field lines contained in the infinite magnetic field region; the size parameters of the specified ellipse in the magnetic field display parameters include: the size parameters of the specified ellipse corresponding to each closed magnetic field line, the size parameters of the specified ellipse corresponding to each open magnetic field line, and the tangent parameters of the specified ellipse.

[0080] Based on the above description, the above step S308 can be implemented by the following steps 30-33:

[0081] Step 30 , for each closed magnetic field line in the near magnetic field region, generating a current closed magnetic field line based on the size parameters of the specified ellipse corresponding to the current closed magnetic field line.

[0082] The magnetic field display parameters include the second number of closed magnetic field lines set in the near magnetic field area, and the size of the minor axis radius and the major axis radius of the specified ellipse required for generating each closed magnetic field line. In a specific implementation, each of the second number of closed magnetic field lines included in the near magnetic field area can be used as the current closed magnetic field line in sequence, and then the current closed magnetic field line is generated through the following steps 40-42:

[0083] Step 40, obtaining a target ellipse according to the size parameters of the designated ellipse corresponding to the current closed magnetic field line.

[0084] The size parameters of the designated ellipse corresponding to the current closed magnetic field line include: the size of the major axis radius and the minor axis radius of the ellipse; according to the size of the major axis radius and the minor axis radius of the ellipse, an ellipse can be obtained.

[0085] Step 41, scaling the target ellipse to obtain a sheared ellipse.

[0086] Scaling the target ellipse can also be understood as deforming the target ellipse. In order to meet the actual magnetic field effect, the horizontal coordinate value on the ellipse is usually scaled in the vertical axis direction as the vertical coordinate value of the target ellipse increases. Specifically, the horizontal coordinate value of the target ellipse is enlarged as the vertical coordinate value increases, and the ellipse after the enlargement operation is determined as the shear ellipse, such as Figure 7 FIG. 1 is a schematic diagram of a shear ellipse provided in an embodiment of the present invention. Figure 7The ellipse in the middle is the target ellipse, and the teardrop-shaped ellipse outside the target ellipse is the shear ellipse.

[0087] In practical applications, after scaling the target ellipse to obtain the shear ellipse, the shear ellipse needs to be stroked to obtain an edge contour with a specified width around the shear ellipse; then the edge contour is set to a third color. The above-mentioned specified width can be set according to research and development requirements, for example, it can be set to 10cm or 15cm, etc., and the specific color of the above-mentioned third color can also be set according to research and development requirements. The shear ellipse can be used to characterize the closed magnetic field lines. Stroke the shear ellipse can further distinguish the boundaries of each closed magnetic field line. After stroking the shear ellipse, the preliminary shape of the closed magnetic field line can be obtained.

[0088] In a specific implementation, the stroke process can be to repeatedly generate a shear ellipse, except that the major axis radius of the target ellipse is slightly enlarged to obtain a slightly larger shear ellipse, and then the smaller shear ellipse is subtracted from the larger shear ellipse to obtain the stroked shear ellipse.

[0089] Step 42, setting the color and transparency inside the shear ellipse, and setting the color outside the shear ellipse, and determining the set shear ellipse as the current closed magnetic field line.

[0090] In a specific implementation, the color inside the shear ellipse can be set to the first color, the color outside the shear ellipse can be set to the second color, and the transparency inside the shear ellipse can be set to a preset value; wherein the transparency inside the shear ellipse is used to indicate the magnetic field strength, and as the size of the shear ellipse increases, the value of the transparency setting inside the shear ellipse becomes smaller.

[0091] The first color, the second color and the preset value can be the default values ​​set according to the research and development requirements, or they can be the specific values ​​input by the user according to the requirements. Specifically, the larger the size of the shear ellipse, the smaller the value of the transparency setting in the shear ellipse. Generally, the smaller the value of the transparency setting, the more transparent it is, which can also be understood as the lighter the color here; at the same time, the smaller the value of the transparency setting, the smaller the magnetic field strength.

[0092] Step 31, combining the generated second number of closed magnetic field lines to obtain a near magnetic field region; wherein the magnetic field radius of the closed magnetic field lines in the near magnetic field region increases from inside to outside, and the magnetic field radius matches the size of the specified ellipse corresponding to the closed magnetic field line.

[0093] In a specific implementation, the position of the target planet is taken as the combination center, and in the direction where the target planet shields the virtual storm, the second number of closed magnetic field lines are combined in order from the magnetic field radius of the closed magnetic field line to the largest, to obtain the nearby magnetic field area. Figure 8The figure shows a schematic diagram of the nearby magnetic field region containing two closed magnetic field lines. Figure 8 The position where the two closed magnetic field lines intersect is the center position of the target planet.

[0094] Step 32 : for each opening magnetic field line in the infinite magnetic field region, generate the current opening magnetic field line according to the size parameters and tangent parameters of the specified ellipse corresponding to the current opening magnetic field line.

[0095] In the specific implementation, according to the size parameters of the ellipse and the tangent parameters of the specified ellipse in the magnetic field display parameters, multiple ellipses with different eccentricities and two tangents corresponding to each ellipse can be obtained. By combining the ellipses and the tangents of the ellipses, multiple open magnetic field lines of the planet can be simulated, and then the infinite magnetic field area in the direction of the virtual storm shielded by the target planet can be obtained.

[0096] The above magnetic field display parameters include the third number of open magnetic field lines set in the infinite magnetic field region, the size of the short axis radius and the long axis radius of the specified ellipse required to generate each open magnetic field line, and the parameters for generating the tangent corresponding to each specified ellipse. In specific implementation, each of the third number of open magnetic field lines contained in the infinite magnetic field region can be used as the current open magnetic field line in sequence, and then the current open magnetic field line is generated through the following steps 50-53:

[0097] Step 50, obtaining the designated ellipse according to the size parameters of the designated ellipse.

[0098] The size parameters of the designated ellipse corresponding to the open magnetic field line include: the size of the major axis radius and the minor axis radius of the ellipse; according to the size of the major axis radius and the minor axis radius of the ellipse, a designated ellipse can be obtained.

[0099] Step 51, determining two tangent lines of the designated ellipse according to the tangent line parameters, and making the two tangent lines tangent to the designated ellipse.

[0100] The above tangent parameters include the position coordinates of two tangent points on the specified ellipse, and then the two tangent lines of the specified ellipse can be generated using the tangent equation.

[0101] Step 52, determining two tangent points between the designated ellipse and the two tangent lines, and combining the tangent lines above the two tangent points and the portion of the designated ellipse below the two tangent points into an open arc.

[0102] like Fig. 9 The diagram shows a schematic diagram of an open circular arc, which is composed of tangent lines above two tangent points and a portion below the two tangent points in a specified ellipse.

[0103] In practical applications, after obtaining the open circular arc, it is also necessary to stroke the open circular arc to obtain an edge contour with a specified width around the open circular arc; then the edge contour is set to a third color. The above-mentioned specified width can be set according to research and development requirements, and the specific color of the above-mentioned third color can also be set according to research and development requirements. The open circular arc can be used to characterize the open magnetic field lines. Stroke the open circular arc to further distinguish the boundaries of each open magnetic field line. After stroking the open circular arc, the preliminary shape of the open magnetic field line can be obtained.

[0104] In a specific implementation, the stroke can be an open arc that is repeatedly generated, except that the radius of the major axis of the specified ellipse is slightly enlarged to obtain a slightly larger open arc, and then the smaller open arc is subtracted from the larger open arc to obtain the stroked open arc.

[0105] Step 53, setting the upper part of the opening arc to the first color, setting the lower part of the opening arc to the second color, and setting the transparency of the upper part of the opening arc to a preset value, and determining the set opening arc as an opening magnetic field line; wherein the transparency is used to indicate the magnetic field strength, and as the opening width of the opening magnetic field line increases, the value of the transparency setting becomes smaller.

[0106] The first color, the second color and the preset value can be the default values ​​set according to the research and development requirements, or they can be the specific values ​​input by the user according to the requirements. Specifically, the larger the opening width of the opening magnetic field line, that is, the larger the opening width of the opening arc, the smaller the value of the transparency setting in the opening arc. Generally, the smaller the value of the transparency setting, the more transparent it is, which can also be understood as the lighter the color here; at the same time, the smaller the value of the transparency setting, the smaller the magnetic field strength.

[0107] Step 33, combining the generated third number of open magnetic field lines to obtain an infinite magnetic field region; wherein the opening widths of the open magnetic field lines in the infinite magnetic field region increase from inside to outside.

[0108] In the specific implementation, the position of the target planet is taken as the combination center, and in the direction where the target planet shields the virtual storm, the third number of open magnetic field lines are combined in sequence from the opening width of the open magnetic field lines small to large to obtain an infinite magnetic field region.

[0109] Step S310, combining the first magnetic field region and the second magnetic field region according to the relative directions to obtain the magnetic field region of the target planet under the action of the virtual storm.

[0110] In specific implementation, with the location of the target planet as the center, a first magnetic field region is set in the relative direction between the target planet and the virtual storm, and a third magnetic field region is set in the direction where the target planet shields the virtual storm, to obtain the magnetic field region of the target planet under the action of the virtual storm. Fig.10 Shown is a schematic diagram of the magnetic field region of the target planet under the influence of the virtual storm.

[0111] The simulation method of the planetary magnetic field in the above virtual scene can use a combination of several ellipses with different eccentricities to generate the magnetic field area of ​​the planet facing the virtual storm; use a combination of semi-ellipses and shear ellipses to generate the near magnetic field area behind the planet; use a combination of semi-ellipses and semi-ellipse tangents to generate an infinite magnetic field area with an opening. This method quickly generates the magnetic field of the planet under the influence of the virtual storm in the virtual scene based on the size information of the planet. At the same time, this method visualizes the magnetic field of a single planet, which improves the richness of the game screen.

[0112] The embodiment of the present invention also provides another method for simulating the magnetic field of a planet in a virtual scene. The method is implemented on the basis of the above embodiment. The method focuses on describing the specific process of simulating the magnetic field effect of the planet under the action of the virtual storm of the star in the local coordinate system corresponding to the target planet; Fig.11 As shown, the method comprises the following specific steps:

[0113] Step S402, obtaining the position information and size information of the target planet.

[0114] Step S402, constructing a local coordinate system with the position of the target planet as the origin, the direction of the line connecting the position of the target planet and the star as the vertical axis direction, and the direction perpendicular to the vertical axis direction as the horizontal axis direction.

[0115] In the specific implementation, since there are multiple planets in the virtual scene, in order to quickly obtain the magnetic field effect corresponding to each planet, each planet is required to take itself as the origin, the direction of the line connecting the star and the planet as the vertical axis, and the left side of the vertical axis as the horizontal axis to construct the local coordinate system corresponding to the planet.

[0116] Step S406, determining the angle between the longitudinal axis of the local coordinate system and the longitudinal axis of the world coordinate system where the star is located.

[0117] Step S408: multiply the angle by a preset rotation matrix to obtain the coordinate value of the pixel point in the virtual scene in the local coordinate system.

[0118] Since the planets and stars are initially set in the world coordinate system, that is, each pixel in the virtual scene is also set in the world coordinate system, by substituting the angle into the preset rotation matrix, the coordinate value of each pixel in the virtual scene in the local coordinate system can be calculated, so that the magnetic field area of ​​the target planet under the influence of the virtual storm can be obtained in the local coordinate system later.

[0119] Step S410, determining the relative direction between the virtual storm caused by the star and the target planet according to the position information of the target planet.

[0120] Step S412: determining the magnetic field display parameters of the target planet based on the size information of the target planet.

[0121] The above-mentioned magnetic field display parameters may include: a first number of magnetic field lines contained in a first magnetic field region of the target planet facing the direction of the virtual storm, a second number of nearby magnetic field regions generated by the target planet blocking the virtual storm, and a third number of infinitely far magnetic field regions generated by the target planet blocking the virtual storm, as well as size parameters of a specified ellipse used to generate the magnetic field region of the target planet and tangent parameters of the specified ellipse.

[0122] Step S414, obtaining the magnetic field region of the target planet under the virtual storm according to the magnetic field display parameters, the relative direction and the coordinate values ​​of the pixel points in the virtual scene in the local coordinate system.

[0123] For the first magnetic field region of the target planet facing the direction of the virtual storm: first, two ellipses are determined according to the coordinate values ​​of the pixel points in the virtual scene in the local coordinate system and the major axis radius and minor axis radius of the specified ellipse; then, with the Y axis as the dividing line, 1 / 2 of each ellipse is taken to form a combined ellipse; then, the combined ellipse is stroked to obtain a stroked combined ellipse (one combined ellipse corresponds to one magnetic flux line); the above operation is repeated to generate a first number of stroked combined ellipses, and the stroke color of each combined ellipse and the color inside the ellipse (that is, the color of the pixel point) are set, and then the first number of color-set combined ellipses are merged to obtain the first magnetic field region.

[0124] For the infinite magnetic field region generated by the target planet blocking the virtual storm: first generate an ellipse, then use the tangent equation to generate two tangents of the ellipse, set the part above the tangent and inside the ellipse to white, and the part below the tangent and the ellipse to black; then stroke the part above the tangent point of the tangent and the part below the ellipse to obtain the stroked magnetic field lines. Repeat the above steps to obtain the third number of open magnetic field lines, and combine the third number of open magnetic field lines to obtain the infinite magnetic field region.

[0125] For the near magnetic field region generated by the target planet blocking the virtual storm: first, construct the target ellipse according to the ellipse size parameters, and then in the Y-axis direction, as the y value increases, enlarge the coordinates of the target ellipse in the X-axis direction to obtain the shear ellipse; repeat the above steps to obtain a second number of shear ellipses of different sizes, combine and stroke the second number of shear ellipses to obtain the near magnetic field region, where one shear ellipse corresponds to a magnetic field line.

[0126] Finally, by combining the above three magnetic field regions, we can obtain the magnetic field effect of the target planet under the influence of the virtual storm.

[0127] The simulation method of the planetary magnetic field in the above virtual scene visualizes the planetary magnetic field. At the same time, it uses layers of gradient colors to further accurately express the concepts of safe zones and magnetic fields. At the same time, this method produces logical planetary safe zone effects according to the real physical phenomena of the planetary magnetic field, which is conducive to improving the player's gaming experience.
