Embodiment

[0048] 1) Make a virtual runner video and video background picture that includes animation effects. The steps are:

[0049] (1) Choose an environment with a static background and stable lighting;

[0050] (2) Take a background picture with a video camera;

[0051] (3) Keep the orientation of the camera unchanged, and shoot a character video with an animation effect, as a virtual runner in the game;

[0052] In addition to using a video camera to shoot video, the second way to create an avatar is: first create an animation model in a 3D modeling tool, and select a solid color background as the video background, and then render the video with animation effects.

[0053] 2) In the virtual scene of the game, create a billboard and display the video as a texture on the billboard. The steps are:

[0054] (1) Pass the video file name as a parameter to the video texture interface provided by the existing game engine;

[0055] (2) according to the position and the size of the virt...

Abstract

The present invention discloses a drawing method for a vedio texture-based virtual runner. The method is mainly applied in a game. Firstly, a virtual runner video comprising animation effect and a video background picture are manufactured; then the video is used as texture to be displayed on a billboard in a game scene; the video texture and the background picture are transferred into a pixel tinter, and a video background is eliminated; the switching of a character animation in a normal skinned mesh form and the video texture is realized in terms of the distance from a view point; finally, a series of key points are stored to be used as the moving path of the virtual runner. The present invention uses character modeling based on the video to replace a normally used skinned mesh, thereby greatly reducing game rendering expense; a video animation can draw material from the reality, thereby reducing the workload of 3D character modeling.

Description

technical field [0001] The invention relates to the field of game development, in particular to a method for drawing virtual runners based on video textures. Background technique [0002] In many racing games, virtual runners can compete with real user avatars in the scene, which enhances the realism and entertainment of the system. Simulation of virtual runners, a category of large-scale crowd simulation. [0003] Large-scale group motion simulation is to study the movement characteristics and laws of crowds in various environments and plots, establish a simulation model of large-scale group motion, and realistically display large-scale group motion in a three-dimensional manner in a computer-generated space (virtual environment). group movement process. Large-scale group motion simulation technology provides analysis and demonstration tools for crowd motion, and is widely used in a wide range of fields. Crowd simulation can be used to successfully establish a crowd flow...
