Class GLFunctionLoader_windows

panamagl.platform.windows.GLFunctionLoader_windows

All Implemented Interfaces:

panamagl.opengl.GLFunctionLoader

public class GLFunctionLoader_windows
extends Object
implements panamagl.opengl.GLFunctionLoader

Resolve OpenGL functions with wglGetProcAddress, falling back on the symbols exported by opengl32.dll (GL 1.1) for which wglGetProcAddress returns nothing. These symbols are looked up in opengl32.dll as already loaded by NativeLibLoader. A GL context must be current on the calling thread. Addresses may depend on the context pixel format, which is why each GL instance keeps its own cache.
