Validating shaders, allows us to find errors on run-time instead of the shader failing and producing corrupt output. HLSL does this upon compilation inside XNA, but we have to wait until out shader compiles, which happens at run time.GLSL
Validating shaders, allows us to find errors on run-time instead of the shader failing and producing corrupt output. HLSL does this upon compilation inside XNA, but we have to wait until out shader compiles, which happens at run time.GLSL is the OpenGL Shader Language, and is the OpenGL version of HLSL for DirectX. It allows us to manipulate the scene on a per vertex and per fragment basis, giving us total control.
