[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] like Figure 1 As shown in Figure 3, a method for generating a graphics rendering animation according to a first aspect embodiment of the present invention includes:

[0032] S100, Establish the display layer and the handwriting rendering layer;

[0033] S200: Obtain the target graphic to the display layer, and form the anchor point outline of the target graphic on the display layer according to the target graphic;

[0034] S300, Use the display layer as a mask for the handwriting rendering layer;

[0035] S400, the handwriting rendering layer uses the anchor point outline as the boundary to confirm at least one rendering path;

[0036] S500: Render the target graphic step by step according to the rendering path;

[0037] S600 records the rendering process of the handwriting rendering layer to form an animation file.

[0038] Specifically, this can be achieved using Adobe Illustrator. Create a canvas in Adobe Illustrator, then create two layers: a presentation layer and a handwriting rendering layer. Place the handwriting rendering layer on top of the presentation layer, and export the generated AI file as an SVG file.

[0039] The generation method of this invention first forms anchor point outlines based on the input target graphic, then uses the anchor point outlines on the display layer as a mask for the handwriting rendering layer, and then confirms the rendering path based on the anchor point outlines as boundaries, so that the rendering path is basically consistent with the shape of the target graphic, and then performs rendering and generates animation. The anchor point outlines are on the display layer and will not have any impact on the display of the handwriting rendering layer. This design can improve the smoothness of the generated target graphic and improve the generation effect of text graphic animation.

[0040] In some embodiments of the present invention, such as Figure 2 As shown, in step S400, the handwriting rendering layer confirms at least one rendering path bounded by the anchor point outline, including:

[0041] S410. Set multiple rendering points within the anchor point outline along the extension direction of the target graphic.

[0042] S420. Connect two adjacent rendering points among multiple rendering points to obtain at least one rendering path.

[0043] It should be noted that after obtaining the target graphic, this system can identify the trend of the extension of the target graphic outline, and then randomly arrange multiple rendering points within the anchor point outline. The rendering path is obtained by connecting two adjacent rendering points. The rendering path is relatively smooth. Using the rendering path to guide the rendering process can make the rendering of the target graphic smoother and improve the animation presentation effect.

[0044] Specifically, there can be multiple rendering paths. For example, if you input the letter "a", you can split the letter "a" into two rendering paths: "c" and an inverted "L". If you input the letter "l", you can directly generate a single rendering path. Of course, you can also input letter strings such as "all". For letter strings such as "all", you can analyze different letters and then split them into different rendering paths.

[0045] In some embodiments of the present invention, such as Figure 3 As shown, step S500, rendering the target graphic step by step according to the rendering path, includes:

[0046] S510. Determine the beginning and end of the rendering path according to the set rendering direction.

[0047] S520. Determine the circumferential neighboring region of each first pixel point as the center of each first pixel point on the handwriting rendering layer of the rendering path, wherein the circumferential neighboring region is the area range that is less than a first set spacing away from the first pixel point.

[0048] S530 constrains the circumferential adjacent regions based on the anchor point contour to form a rendering region corresponding to each first pixel.

[0049] S540. From the beginning to the end of the rendering path, gradually color the uncolored second pixels within the rendering area corresponding to each first pixel.

[0050] It should be noted that the handwriting rendering layer is composed of an array of pixels. The rendering is guided by the rendering path. The first pixel is formed at the position where the rendering path overlaps with the handwriting rendering layer. During rendering, the second pixels around each first pixel are gradually colored together, thereby gradually coloring the area within the anchor point outline along the rendering path. This makes the rendering process orderly and improves the animation effect.

[0051] Specifically, the rendering direction can be set by the user, such as from the top of the handwriting rendering layer to the bottom of the handwriting rendering layer, or from the left side of the handwriting rendering layer to the right side of the handwriting rendering layer.

[0052] The first preset spacing can be set by the user, and is generally the width of the stroke within the anchor point outline. The circumferential adjacent area is equivalent to the area within the circumference obtained by taking the first pixel as the center and using the first preset spacing as the radius.

[0053] In some embodiments of the present invention, gradually coloring the uncolored second pixels in the rendering area corresponding to each first pixel includes: sequentially coloring the uncolored second pixels in the rendering area corresponding to each first pixel at a set time interval. Specifically, the set time interval can be set by the user, so that the rendering area is gradually colored at a constant gradient rate, thereby improving the animation effect of the rendering.

[0054] In some embodiments of the present invention, constraining the circumferential adjacent region according to the anchor point contour to form a rendering region corresponding to each first pixel includes: determining whether any position of the circumferential adjacent region is within the anchor point contour; if not, deleting the position of the circumferential adjacent region below the anchor point contour to form a rendering region.

[0055] After obtaining the circumferential neighboring region, the regions in the circumferential neighboring region that are not within the anchor point outline are deleted, and the remaining regions form the rendering region. This allows the rendering region to fill the region within the anchor point outline without exceeding it, making the strokes smoother and improving the animation rendering effect.

[0056] In some embodiments of the present invention, setting multiple rendering points within the anchor point contour along the extension direction of the target graphic includes: sequentially setting rendering points along the extension direction of the target graphic, and setting the next rendering point at a position within the anchor point contour at a second predetermined spacing from the previously set rendering point.

[0057] This system can make a basic determination of the extension direction of the target graphic. For the setting of multiple rendering points, an initial rendering point can be randomly set within the anchor point outline. The next rendering point is selected at intervals of the second set distance along the approximate extension direction. The position of the rendering point is then determined to see if it is within the anchor point outline. If it is, the rendering point is determined to be formed. If not, the position of the next rendering point relative to the previous rendering point is adjusted to form another rendering point. The system then checks whether the rendering point is within the anchor point outline again. This process is repeated until the next rendering point is located within the anchor point outline.

[0058] In some embodiments of the present invention, the rendering process of the handwriting rendering layer is associated with a timeline to form an animation file.

[0059] Specifically, by linking the rendering process with the timeline, users gain more control over the playback of animations, such as pausing playback, callbacks, and specifying playback positions, thereby optimizing the animation playback effect.

[0060] The generation system according to the second aspect of the present invention, such as Figure 4 As shown, it includes: an input module 100 for inputting a target graphic; and a processing module 200 connected to the input module 100. The processing module 200 establishes a display layer and a handwriting rendering layer. The processing module 200 acquires the target graphic into the display layer and forms the anchor point outline of the target graphic on the display layer based on the target graphic. The processing module 200 uses the display layer as a mask for the handwriting rendering layer. The handwriting rendering layer confirms at least one rendering path based on the anchor point outline. The processing module 200 renders the target graphic step by step according to the rendering path. The processing module 200 records the rendering process of the handwriting rendering layer to form an animation file.

[0061] The input module 100 can be composed of a touch screen or a mouse and display screen, while the processing module 200 can be composed of an MCU or CPU and auxiliary circuits.

[0062] The generation system of this invention can improve the smoothness of the generated target graphics and enhance the generation effect of text and graphic animation.
