BGL2 - An OpenGL 2.1 render backend for bevy.

BGL2 supports:

• OpenGL 2.1
• WebGL 1.0
• GLES 2.0 (theoretically, needs integration & testing)
• Polyfill for OpenGL on MacOS (Currently very cursed, needs work)

This project is mostly just a silly experiment for fun. I don't currently plan on actively maintaining this, and when I do work on it I will probably make erratic API breaking changes. Use at your own risk.

WebGL 1:

Run locally with bevy web cli

bevy run --release --example load_gltf web --open

Windows XP:

Tested with XP Pro SP3 32-bit on:

• VMware with Guest Additions OpenGL driver

GL_VENDOR   : VMware, Inc.
GL_RENDERER : Gallium 0.4 on SVGA3D; build: RELEASE;
GL_VERSION  : 2.1 Mesa 10.0 (git-5da4fa2)

• VirtualBox with Mesa for windows 17.0.0

GL_VENDOR   : VMware, Inc.
GL_RENDERER : Gallium 0.4 on llvmpipe (LLVM 3.7, 128 bits)
GL_VERSION  : 3.0 Mesa 17.0.0

To compile for Windows XP, use thunk. cargo install thunk-cli
