Web7 de abr. de 2009 · First: OpenGL will perform conversions from any format/type to the internalformat, with only a couple of exceptions (spelled out by i.e. EXT_texture_integer, ARB_depth_texture etc.) So there is no single mapping of client format/type to something like GL_FORMAT_R16G16B16A16_FLOAT. These are all valid mappings:
