44e5c31af7Sopenharmony_ciDescription:
45e5c31af7Sopenharmony_ci
46e5c31af7Sopenharmony_ciRendering tests create a texture buffer object and render to the default
47e5c31af7Sopenharmony_ciframebuffer using the texture buffer as different data sources. The texture
48e5c31af7Sopenharmony_cibuffer object is used as vertex array, index array, vertex texture and fragment
49e5c31af7Sopenharmony_citexture. Rendering using the texture buffer object simultaneously in different
50e5c31af7Sopenharmony_ciways is also tested.
51e5c31af7Sopenharmony_ci
52e5c31af7Sopenharmony_ciModifying tests create a texture buffer object, modify it and render it to the
53e5c31af7Sopenharmony_cidefault framebuffer using it as fragment texture.
54e5c31af7Sopenharmony_ci
55e5c31af7Sopenharmony_ciModify render tests will create texture buffer object, modify it and render it
56e5c31af7Sopenharmony_cito the default framebuffer.
57e5c31af7Sopenharmony_ci
58e5c31af7Sopenharmony_ciRender modify tests will create a tests buffer object render it to default
59e5c31af7Sopenharmony_ciframebuffer, modify it and render it again to default framebuffer as fragment
60e5c31af7Sopenharmony_citexture.
61e5c31af7Sopenharmony_ci
62e5c31af7Sopenharmony_ciAll textures use RGBA8 format and buffer data is always used as unsigned bytes.
63e5c31af7Sopenharmony_ciUsed values for bytes are also limited to simplify verification. Verification
64e5c31af7Sopenharmony_ciis always performed at the end of the test.
