|
|
*
|
|
* This code is originated from the modules/glshared/glsTextureTestUtil.hpp
|
|
* and it is tightly coupled with the GLES and Vulkan texture tests!
|
|
*
|
|
* About coordinates:
|
|
* + Quads consist of 2 triangles, rendered using explicit indices.
|
|
* + All TextureTestUtil functions and classes expect texture coordinates
|
|
* for quads to be specified in order (-1, -1), (-1, 1), (1, -1), (1, 1).
