Description

Technical Field

[0001] This invention relates to the field of simulation technology, specifically to a method, apparatus, equipment, and storage medium for simulating the motion of a scrolling screen. Background Technology

[0002] To shorten R&D cycles and improve user experience, automakers need to use visualization software to create virtual reality engineering prototypes for quality assessment. Deltagen software, a high-end visualization content creation tool from Dassault Systèmes, can handle large amounts of virtual reality engineering prototypes and run them smoothly, supporting real-time review.

[0003] Currently, rollable screens are used in the mobile phone industry and will be used in the automotive industry in the future, as virtual reality engineering prototypes need to simulate their motion states.

[0004] Existing technologies for displaying complex movements of engineering machinery products in visualization software include a method for virtual visualization of engineering machinery products in an immersive virtual reality environment. This method proposes importing the CAD engineering data of the engineering machinery product into Deltagen to generate a virtual visualization model; exporting the motion component model group that needs to be animated; importing the exported file into the animation editing software Maya, animate the motion component model in Maya, exporting the edited animation model as a .wrl file; and importing the exported .wrl animation data into Deltagen to realize the virtual visualization model display.

[0005] The limitations of this technology:

[0006] ① High learning cost: It requires the use of other software to edit complex animations, and requires the production staff to master multiple software programs;

[0007] ②Long production cycle: The animation production cycle is increased in the process of "Deltagen export - Maya import - Maya editing - Maya export - Deltagen import";

[0008] ③ Difficult to modify: Since the animation cannot be edited in Deltagen, the above steps must be repeated if modifications are required. Summary of the Invention

[0009] This invention provides a method, apparatus, device, and storage medium for motion simulation of a scrolling screen, which allows for real-time observation and modification of the motion simulation effect, improving the efficiency and quality of motion simulation and solving the problems of needing to learn additional software to create animations, long animation production cycles, and difficulty in modifying animations.

[0010] The technical solution of this invention is described below in conjunction with the accompanying drawings:

[0011] In a first aspect, embodiments of the present invention provide a method for simulating the motion of a rollable screen, comprising:

[0012] Step 1: Import the 3D model of the scroll screen into Deltagen software;

[0013] Step 2: Subdivide the 3D model of the scroll screen with uniform precision. After subdivision, retopologically analyze the 3D model of the scroll screen with uniform precision.

[0014] Step 3: Check the surface normal direction of the 3D model of the scroll screen and adjust the model surface with incorrect normal direction to the correct direction;

[0015] Step 4: Classify the scrollable screen components;

[0016] Step 5: Assign materials to the scrollable screen components;

[0017] Step 6: Calculate the UV coordinates of the component's material;

[0018] Step 7: Create a motion simulation process for the motion components, and set keyframes for the extreme positions of the scroll screen.

[0019] Step 8: For the material change component, set the transparency property; adjust the scroll animation to the two extreme positions, adjust and record the UV parameters at each point;

[0020] Step 9: Design the program in the logic network editor to match the animation state at the extreme positions with the corresponding material UV state;

[0021] Step 10: The scrolling screen motion simulation is complete, triggering the model display.

[0022] Furthermore, in step two, the precision of the scroll screen 3D model is set to 0.1 for subdividing according to a uniform precision; the precision of the scroll screen 3D model topology is also set to 0.1 according to a uniform precision.

[0023] Furthermore, in step four, the scroll screen is first classified into moving components and fixed components;

[0024] The motion components include material-changing components and material-invariant components; the material-changing components are grouped according to their material; the material-invariant components are also grouped according to their material.

[0025] The fixing components are grouped according to their materials.

[0026] Furthermore, in step five, changes in material properties are not considered, and no transparency property is added.

[0027] Furthermore, the specific method for step seven is as follows:

[0028] The frame rate is set to 25 frames per second;

[0029] Create a new timeline, select the motion component, and then create a new animation;

[0030] At frame 0, adjust the scrolling screen to its maximum state and set a keyframe;

[0031] Adjust the scroll screen to its minimum state at frame 50 and set a keyframe.

[0032] Furthermore, in step eight, a black and white texture is selected for the transparent texture. After inserting the black and white texture into the material editor, the maximum state of the scroll screen is obtained. The parameters are adjusted to ensure that the screen is fully displayed, and the UV parameters are recorded at this time. After inserting the black and white texture into the material editor, the minimum state of the scroll screen is obtained. The parameters are adjusted to ensure that the part of the screen that exceeds the scroll screen is hidden, and the UV parameters are recorded at this time. Thus, the UV parameters of the two extreme positions of the scroll screen animation are obtained.

[0033] Furthermore, in step nine, the designed program includes three functions: forward and reverse playback of motion components, material fading and revealing, and synchronized revealing and disappearing of motion components and materials.

[0034] The method for obtaining the forward and reverse playback function of the motion component is as follows:

[0035] a1) Add a trigger and set the trigger mode;

[0036] a2) Add a counter, set the maximum value to 2, the increment to 1, and count in a loop;

[0037] a3) Add a signal separator, using the counter result as the selection condition and the trigger as the input;

[0038] a4) Add motion component animation. When the counter is 1, it plays forward; when the counter is 2, it plays backward. After playing backward, the counter is reset to obtain the forward and backward playback function of the motion component.

[0039] The method for obtaining the material fading and revealing functions is as follows:

[0040] b1) Add a timer and set the period;

[0041] b2) Add a time percentage module, with the period as the denominator and the timer duration as the numerator;

[0042] b3) Add a two-dimensional vector and set its value to the UV difference;

[0043] b4) Add a multiplication module, using the time percentage module and the number module from steps b2) and b3) as inputs, to obtain the UV adjustment value;

[0044] b5) Add a two-dimensional vector, and set its value to the initial UV parameters;

[0045] b6) Add an addition module, using the UV adjustment values ​​and initial UV parameters from steps b4) and b5) as inputs, to obtain the forward UV parameters;

[0046] b7) Add the appropriate material;

[0047] b8) Add a two-dimensional vector and set its value to the final UV parameter;

[0048] b9) Add a subtraction module, using the final UV parameter as the minuend and the UV adjustment value as the subtrahend, to obtain the reverse UV parameter;

[0049] b10) Add the corresponding material to obtain the material fading and revealing functions;

[0050] The method for obtaining the function of synchronizing the movement of components with the visibility of materials is as follows:

[0051] C1) Add a counter, set the maximum value to 2, the increment to 1, and count in a loop;

[0052] C2) Add a two-dimensional vector;

[0053] C3) Add a judgment module, which takes the count value and vector X value (0) of steps C1) and C2) as input, and judges whether the counter is 0. If it is 0, the output signal is "true".

[0054] C4) Add a condition selection module, taking the vector Y value (1) from steps C2) and C3) and the judgment output signal as input. If the counter is 0, output 1 to reset the counter.

[0055] C5) Add a signal selector, which takes the count value of step C1), forward UV parameters and reverse UV parameters as input, and outputs the results to the material module to realize the function of coordinated linkage between the component and material changes during the movement.

[0056] Secondly, embodiments of the present invention also provide a scrollable screen motion simulation device, comprising:

[0057] The import module is used to import 3D models of scrollable screens into Deltagen software;

[0058] The topology module is used to subdivide the 3D model of the scroll screen with uniform precision, and then topologically reshape the 3D model of the scroll screen with uniform precision.

[0059] The inspection module is used to check the surface normal direction of the 3D model of the scroll screen and adjust the model surface with incorrect normal direction to the correct one.

[0060] The classification module is used to classify the scrollable screen components;

[0061] The Material Assignment module is used to assign materials to the scrollable screen components;

[0062] The calculation module is used to calculate the UV mapping of the component's material.

[0063] Create a simulation module to simulate the motion of moving components, and set keyframes for the extreme positions of the scroll screen.

[0064] Adjust the recording module to set the transparency property for components with material changes; adjust the scroll animation to two extreme positions, adjust and record the UV parameters at each point;

[0065] The design module is used to design programs in the logic network editor to match the animation state at extreme positions with the corresponding material UV state.

[0066] The trigger module is used to trigger the model display after the scrolling screen motion simulation is completed.

[0067] Thirdly, embodiments of the present invention also provide a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement a scrollable screen motion simulation method as described in any of the embodiments of the present invention.

[0068] Fourthly, embodiments of the present invention also provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements a scrollable screen motion simulation method as described in any of the embodiments of the present invention.

[0069] The beneficial effects of this invention are as follows:

[0070] This invention solves the problems of needing to learn additional software to create animations, long animation production cycles, and difficulty in modifying animations. Furthermore, since all operations are completed in Deltagen software, the effects of motion simulation can be observed in real time and modified at any time, thus improving the efficiency and quality of motion simulation.

[0078] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0079] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0080] Example 1

[0081] Figure 1 This is a flowchart of a scrollable screen motion simulation method provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of scrollable screen motion simulation. The method can be executed by the scrollable screen motion simulation device in this embodiment of the present invention. The device can be implemented in software and / or hardware. The method specifically includes the following steps:

[0082] Step 1: Import the 3D model of the scroll screen into Deltagen software;

[0083] Step 2: Subdivide the 3D model of the scroll screen with uniform precision. After subdivision, retopologically analyze the 3D model of the scroll screen with uniform precision.

[0084] The precision of the scroll screen 3D model is set to 0.1 for subdividing the model with uniform precision; the precision of the scroll screen 3D model topology is also set to 0.1 for uniform precision.

[0085] Step 3: Check the surface normal direction of the 3D model of the scroll screen and adjust the model surface with incorrect normal direction to the correct direction;

[0086] Enable the normal display check mode to check if the normal direction is correct. If it is incorrect, adjust the normal direction using the shortcut key "N" to ensure that the direction of all surfaces in the model is correct.

[0087] Step 4: Classify the scrollable screen components;

[0088] See Figure 2 The scroll screen is first classified into moving components and fixed components;

[0089] The motion components include material-changing components and material-invariant components; the material-changing components are grouped according to their material; the material-invariant components are also grouped according to their material.

[0090] The fixing components are grouped according to their materials.

[0091] Step 5: Assign materials to the scrollable screen component; do not consider material changes and do not add transparency properties.

[0092] Adjust the scroll screen to its minimum state. In the "Transparency texture" property, select "Clamp" for "Repeat mode" and adjust the "Translation" parameter to ensure that the part of the screen that exceeds the scroll screen is hidden. Record the UV parameters at this time.

[0093] Step 6: Calculate the UV coordinates of the component's material;

[0094] UVs are calculated separately for each component. The "Planar" preset is used for planar components, and the "Triplanar" preset is used for non-planar components to ensure that the texture of each component is correct.

[0095] Step 7: Create a motion simulation process for the motion components, and set keyframes for the extreme positions of the scroll screen.

[0096] The specific method is as follows:

[0097] 1) The frame rate is set to 25 frames per second;

[0098] 2) Open the "Animation list" window, create a new "Timeline", select the motion component, and create a new "Animation";

[0099] 3) Adjust the scrolling screen to its maximum state at frame 0 and set a keyframe;

[0100] 4) At frame 50, adjust the scrolling screen to its minimum state and set a keyframe;

[0101] Step 8: For the material change component, set the transparency property; adjust the scroll animation to the two extreme positions, adjust and record the UV parameters at each point;

[0102] This section uses a screen as an example to illustrate the material adjustment process.

[0103] 1) Open the material editor for the "Screen";

[0104] 2) Check the "Transparency texture" property, and select "From file" for "Source";

[0105] 3) Insert a black and white texture, see Figure 3 ;

[0106] 4) Adjust the scrollable screen to its maximum state. In the "Transparency texture" property, select "Clamp" for "Repeat mode" and adjust the "Translation" parameter to ensure that the screen is fully displayed. Record the UV parameters at this time.

[0107] 5) Adjust the scroll screen to its minimum state. In the "Transparency texture" property, select "Clamp" for "Repeat mode" and adjust the "Translation" parameter to ensure that the part of the screen that exceeds the scroll screen is hidden. Record the UV parameters at this time.

[0108] Step 9: Design the program in the logic network editor to match the animation state at the extreme positions with the corresponding material UV state;

[0109] See Figure 4 The designed program includes three functions: forward and reverse playback of motion components, material fading and revealing, and synchronized revealing and revealing of motion components and materials.

[0110] The method for obtaining the forward and reverse playback function of the motion component is as follows:

[0111] 1) Add a trigger and set the trigger mode to "Click on Scroll Screen";

[0112] 2) Add a counter, set the maximum value to 2, the increment to 1, and count in a loop;

[0113] 3) Add a signal separator, using the counter result as the selection condition and the trigger as the input;

[0114] 4) Add motion component animation. When the counter is 1, it plays forward; when the counter is 2, it plays backward. After playing backward, the counter is reset to obtain the forward and backward playback function of the motion component.

[0115] Using screen material as an example, this explains how to obtain the functions of material fading and fading:

[0116] 1) Add a timer with a period of 2 seconds, and input the trigger signal from the "Motion Component Forward and Reverse Play Program" to "Start";

[0117] 2) Add a time percentage module, with the period as the denominator and the timer duration as the numerator;

[0118] b3) Add a two-dimensional vector and set its value to the UV difference;

[0119] b4) Add a multiplication module, using the time percentage module and the number module from steps b2) and b3) as inputs, to obtain the UV adjustment value;

[0120] b5) Add a two-dimensional vector, and set its value to the initial UV parameters;

[0121] b6) Add an addition module, using the UV adjustment values ​​and initial UV parameters from steps b4) and b5) as inputs, to obtain the forward UV parameters;

[0122] b7) Add screen material and input the current UV parameters into "Translation value";

[0123] b8) Add a two-dimensional vector and set its value to the final UV parameter;

[0124] b9) Add a subtraction module, using the final UV parameter as the minuend and the UV adjustment value as the subtrahend, to obtain the reverse UV parameter;

[0125] b10) Add screen material, input the reverse UV parameters to "Translation value" to obtain material fading and revealing functions;

[0126] Taking screen material as an example, this explains how to achieve the function of synchronizing the visibility of motion components with the material:

[0127] 1) Add a counter, set the maximum value to 2, the increment to 1, and count in a loop. Input the trigger signal from the "Motion Component Forward and Reverse Play Program" to "Increase";

[0128] 2) Add a two-dimensional vector with values ​​set to (0, 1);

[0129] 3) Add a judgment module, which takes the count value and vector X value (0) from steps C1) and C2) as inputs to judge whether the counter is 0. If it is 0, the output signal is "true".

[0130] 4) Add a condition selection module, taking the vector Y value (1) from steps C2) and C3) and the judgment output signal as input. If the counter is 0, output 1 to reset the counter.

[0131] 5) Delete one of the two screen material modules in the "Material Fade and Reveal Procedure", leaving only one material module (two material modules are added to the program to facilitate understanding of the two independent processes of fading and revealing. In actual applications, only one material module is needed, and this step is unnecessary).

[0132] 6) Add a signal selector, which takes the count value of step C1), forward UV parameters and reverse UV parameters as input, and outputs the results to the material module to realize the function of coordinated linkage between the component and material changes during the movement.

[0133] Step 10: The scrolling screen motion simulation is complete, triggering the model display.

[0134] Click on the scroll screen to see its dynamic expansion and contraction effects.
