Description:
|
|
|
|
Texture image specification tests build a complete 2D or cubemap texture
|
|
using the texture image specification functions. The exact order and functions
|
|
used depends on the test case.
|
|
|
|
For glCopyTexImage2D() and glCopyTexSubImage2D() usage the rendering target
|
|
is first filled with meaningful data by rendering a simple textured quad first.
|
|
|
|
Reference texture object is constructed by applying reference versions of the
|
|
same operations to a reference pixel buffer.
|
|
|
|
Finally both the constructed texture is rendered using a simple quad and the
|
|
resulting images are compared against the reference. Nearest-neighbor -filtering
|
|
is used. For cubemap textures each face is rendered separately and all are
|
|
verified. If mipmaps were constructed, texture is rendered multiple times
|
|
sampling texels from different mipmap levels.
