Web11 de jan. de 2012 · 11. Using more than one shader in a scene is quite simple; change the shader, set the values for it, then render the object. Beware, however, switching shaders can be costly, so shader switching should be kept to a bare minimum. There are a few ways to reduce this impact while getting all of the effects you want. WebVertex Shader. Our first shader is the VERTEX_SHADER, which must calculate a vertex position for each vertex which is to be generated. Normally this is one vertex for each vertex we pass into the GL, but with geometry shaders and the like more vertices could be created.
