Description:
|
|
|
|
Rendering tests create a texture buffer object and render to the default
|
|
framebuffer using the texture buffer as different data sources. The texture
|
|
buffer object is used as vertex array, index array, vertex texture and fragment
|
|
texture. Rendering using the texture buffer object simultaneously in different
|
|
ways is also tested.
|
|
|
|
Modifying tests create a texture buffer object, modify it and render it to the
|
|
default framebuffer using it as fragment texture.
|
|
|
|
Modify render tests will create texture buffer object, modify it and render it
|
|
to the default framebuffer.
|
|
|
|
Render modify tests will create a tests buffer object render it to default
|
|
framebuffer, modify it and render it again to default framebuffer as fragment
|
|
texture.
|
|
|
|
All textures use RGBA8 format and buffer data is always used as unsigned bytes.
|
|
Used values for bytes are also limited to simplify verification. Verification
|
|
is always performed at the end of the test.
