Gfx Module

Overview

The Oryol Gfx module is a thin portability wrapper for 3D-APIs and shader languages. The feature set is defined roughly by GLES3 (WebGL2) with a fallback to GLES2 (WebGL). The programming model is similar to Metal, but with even more simplified resource management.

Sample Code

The most important and detailed documentation of the Gfx module is the Samples source code.

Looking at those four samples should give you most of the information necessary to work with the Gfx module:

• Clear Sample
• Triangle Sample
• Shapes Sample
• Texture Loading
• Offscreen Render Targets

Topics

• Rendering Backends
• A Simple Render Loop
• Resource Objects
  • Meshes
  • Textures
  • Render Passes
  • Shaders
