I am not able to use GL_MIRRORED_REPEAT and GL_CLAMP_TO_BORDER in TinyGL (MorphOS 3.12).
Does anyone know if next versions of TinyGL will support these texture wrapping methods? Is any chance or I should avoid the feature?

I think you need to be a bit more specific. Got sample code to illustrate the issue?

Quote:

OpenGL offers four kind of texture wrapping:
1. GL_REPEAT,
2. GL_MIRRORED_REPEAT,
3. GL_CLAMP_TO_EDGE (also known as GL_CLAMP),
4. GL_CLAMP_TO_BORDER.

Differences of these methods of wrapping are very well visualised there (in chapter “Texture Wrapping”):
https://learnopengl.com/Getting-started/Textures

TinyGL in MorphOS allows to use only methods 1 and 3 (code with GL_MIRRORED_REPEAT or GL_CLAMP_TO_BORDER can't be compiled in SDK because gl.h of TinyGL doesn't contain these defines).
I would like to know if reason no support GL_MIRRORED_REPEAT is in hardware or software (implementation of TinyGL). And if is any chance for add support of GL_MIRRORED_REPEAT.

If there are not chance for GL_MIRRORED_REPEAT in TinyGL, it won’t very big problem for me. I will modify a bit my code+textures for use GL_REPEAT instead ofGL_MIRRORED_REPEAT in one place in project. And I will avoid using GL_MIRRORED_REPEAT and GL_CLAMP_TO_BORDER.
