OpenGL 2.1
handicraftsman opened this issue · comments
Any plans on supporting PCs with OpenGL 2.1? Aforementioned Minecraft supports it and its widespread across old PCs like mine.
Does it run on your machine? It should run on GLSL 100+ and any OpenGL with display list support, which im pretty sure 2.1 does. As for future support/plans, I want to support the oldest GL version possible by keeping things simple, just plain old display lists and vertex arrays.
Okay, i will try that in few dayz (cannot use my pc atm).
OpenGL 2.1 is being depreciated for OpenGL 3
You should look into googles Angle - it supports mapping opengl es 2.0 calls to all popular graphics apis, even to metal or webgl. OpenGL ES 3.0 (supported too) doesnt work on webgl, directx 9 and similar old api versions though. Was writing this issue because my pc did not support opengln 3+.
Google Angle looks useful, just writing OpenGL ES and having it work anywhere. However, I do not currently have the resources in order to try it out at the moment.
As for supporting 2.1 and 3.0, it should be simple enough to support display lists and vertex arrays.
Yeah, i understand the resources problem - i have a teapot instead of a proper computer 😄.
Sucle currently renders to either a 2.1 display lists or 3.* vertex buffers, meaning that 2.1 should be supported now.
