start reminder

Fig. 3 illustrates a schematic diagram of key frames of a water ripple animation of a starting reminder according to one or more embodiments of the present invention. Referring to FIG. 3 , the water ripple animation of the starting reminder is an inverted V-shaped water ripple. The inverted V-shaped water ripple first appears in front of the front of the car, then moves forward, fades and disappears at a certain position, and repeats this cycle.

In one or more embodiments, as shown in FIG. 4 , the three-dimensional model 300 generated in step 210 includes a plane 310 for attaching the stripe pattern. It should be noted that the three-dimensional model 300 shown in FIG. 4 is a plane, but it can be understood that the three-dimensional model 300 can be in any shape, as long as the surface for attaching the stripe pattern is a plane. For example, the three-dimensional model 300 may be a triangular prism, a quadrangular prism, a pentagonal prism, etc., and each of these three-dimensional models includes at least one plane for attaching the stripe pattern. Correspondingly, the stripe pattern is a pattern having a plurality of inverted V-shaped stripes arranged in layers, as shown in FIG. 5 . Wherein, the stripes in the stripe pattern gradually change in transparency from top to bottom.

In step 220 , the stripe pattern shown in FIG. 5 is pasted on the plane 310 in the three-dimensional model 300 by stepping along the first direction, so as to generate the water ripple animation as shown in FIG. 3 . Wherein, the first direction refers to the direction in which the water ripples advance. Among them, the stepping method means that before the water ripple fades and disappears, the stripe pattern in one frame of image is attached to the first position of the plane 310, and the stripe pattern in the next frame of image is attached to the second position of the plane 310 , the second position is more forward than the first position along the first direction. For example, a shader is used to attach a stripe pattern to a 3D model. Taking a vertex in the 3D model as an example, the vertex corresponds to the color of the UV coordinate (0, 0) of the texture pattern in the initial frame (that is, sampling ), the vertex corresponds to the color of the UV coordinate (0, 0.01) of the texture pattern in the second frame, the vertex corresponds to the color of the UV coordinate (0, 0.02) of the texture pattern in the third frame, and so on. That is to say, the direction in which the water ripples advance corresponds to the direction of the V coordinate axis. For the same vertex, as the number of frames increases, the V coordinate of its sampled texture pattern also increases accordingly.

In one or more embodiments, as shown in FIG. 6 , the three-dimensional model generated in step 210 includes two planes 320 , 330 for attaching the stripe pattern, and the two planes 320 , 330 are in an inverted V shape. It should be noted that the three-dimensional model 300 shown in FIG. 6 is two planes 320, 330 in the shape of an inverted V, but it can be understood that the three-dimensional model 300 can be in any shape, as long as the two planes for attaching the stripe pattern are in the shape of Make an inverted V shape. For example, the three-dimensional model 300 may be a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, and the like. Correspondingly, the stripe pattern is a pattern having a plurality of parallel straight stripes, as shown in FIG. 7 . Wherein, the stripes in the stripe pattern gradually change in transparency from top to bottom.

In step 220 , the stripe pattern shown in FIG. 7 is pasted on the two planes 320 , 330 in the 3D model 300 by stepping along the first direction, so as to generate the water ripple animation as shown in FIG. 3 . Wherein, the first direction refers to the direction in which the water ripples advance. Among them, the stepping method means that before the water ripple fades and disappears, the stripe pattern in one frame of image is attached to the first position of the two planes 320, 330, and the stripe pattern in the next frame of image is attached to the two planes. At the second position of 320, 330, the second position is more forward than the first position along the first direction. For example, a shader is used to attach a stripe pattern to a 3D model. Taking a vertex in the 3D model as an example, the vertex corresponds to the color of the UV coordinate (0, 0) of the texture pattern in the initial frame (that is, sampling ), the vertex corresponds to the color of the UV coordinate (0, 0.01) of the texture pattern in the second frame, the vertex corresponds to the color of the UV coordinate (0, 0.02) of the texture pattern in the third frame, and so on. That is to say, the direction in which the water ripples advance corresponds to the direction of the V coordinate axis. For the same vertex, as the number of frames increases, the V coordinate of its sampled texture pattern also increases accordingly.

lane change reminder

Fig. 8 illustrates a schematic diagram of key frames of a water ripple animation for a lane change reminder according to one or more embodiments of the present invention. Referring to FIG. 8 , the water ripple animation of the lane change reminder is the water ripple of straight lines. The water ripples of straight stripes first appear in one lane, then move forward, then move down to the adjacent lane and continue to move forward, move to a certain position and start to fade and disappear, and so on.

In one or more embodiments, as shown in FIG. 9 , the three-dimensional model 400 generated in step 210 is a curved three-dimensional model spanning adjacent lanes. The curved three-dimensional model includes a plane 410 for attaching the stripe pattern. It should be noted that the three-dimensional model 400 shown in FIG. 9 is a curved plane, but it can be understood that the three-dimensional model 400 can be in any shape, as long as the surface for attaching the stripe pattern is a plane. For example, the three-dimensional model 400 may be a curved rectangular body. In one or more embodiments, the stripe pattern is a pattern having a plurality of parallel straight-line stripes, as shown in FIG. 10 . Wherein, the stripes in the stripe pattern gradually change in transparency from top to bottom.

In step 220, the stripe pattern shown in FIG. 10 is pasted on the plane 410 in the three-dimensional model 400 by stepping along the first direction, so as to generate the water ripple animation as shown in FIG. 8 . Wherein, the first direction refers to the direction in which the water ripples advance. Wherein, the stepping method means that before the water ripple fades and disappears, the stripe pattern in one frame of image is attached to the first position of the plane 410, and the stripe pattern in the next frame of image is attached to the second position of the plane 410 , the second position is more forward than the first position along the first direction. For example, a shader is used to attach a stripe pattern to a 3D model. Taking a vertex in the 3D model as an example, the vertex corresponds to the color of the UV coordinate (0, 0) of the texture pattern in the initial frame (that is, sampling ), the vertex corresponds to the color of the UV coordinate (0, 0.01) of the texture pattern in the second frame, the vertex corresponds to the color of the UV coordinate (0, 0.02) of the texture pattern in the third frame, and so on. That is to say, the direction in which the water ripples advance corresponds to the direction of the V coordinate axis. For the same vertex, as the number of frames increases, the V coordinate of its sampled texture pattern also increases accordingly. .

In the present invention, the transparency gradient of the stripes in the attached picture is directly implemented in the picture without operating in the shader, which also reduces the complexity of the shader and reduces the performance overhead. In addition, the present invention utilizes the method of dynamically moving UV coordinates to map, which reduces the complexity of motion trajectory calculation.

In one or more embodiments, in step 220 , a shader is used to attach the stripe pattern to one or more surfaces in the 3D model. Specifically, it adjusts the texture coordinates corresponding to the first direction step by step to attach the stripe pattern to one or more surfaces in the three-dimensional model in a stepwise manner along the first direction.

In one or more embodiments, the method 200 for generating a water ripple animation on an automotive instrument panel is implemented on the graphics processor 112 of the automotive instrument panel 100 .
