The exact order and functions 43 used depends on the test case. 44 45 For glCopyTexImage2D() and glCopyTexSubImage2D() usage the rendering target 46 is first filled with meaningful data by rendering a simple textured quad first. 47 48 Reference texture object is constructed by applying reference versions of the 49 same operations to a reference pixel buffer. 50 51 Finally both the constructed texture is rendered using a simple quad and the 52 resulting images are compared against the reference. Nearest-neighbor -filtering 53 is used. For cubemap textures each face is rendered separately and all are 54 verified. If mipmaps were constructed, texture is rendered multiple times 55 sampling texels from different mipmap levels. 56
