The vertex shader thus requires an extra layout specification for its inputs so we can link it with the vertex data. It is also possible to omit the layout (location = 0) specifier and query for the attribute locations in your OpenGL code via glGetAttribLocation, but I'd prefer to set them in the vertex Ver mais GLSL has, like any other programming language, data types for specifying what kind of variable we want to work with.

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.
