This repository contains a collection of shader samples for the GX2 graphics API of the Wii U. The current examples show you the very basics of how to write a shader for the Wii U and how to use it to draw a triangle or a textured quad, but I might expand them in the future. A basic understanding of OpenGL is required, this just shows the Wii U-isms a bit.
These GX2 samples use the new CafeGLSL shader compiler which finally allows Wii U homebrew developers to use their own shaders without having to use hand-assembled shaders.
- Triangle - Draws a triangle
- Textured Quad - Draws a texture on a full-screen quad
Tank Trap(releasing soon!) - A game-jam game made that also uses CafeGLSL!- Immaterial (Blog Article) - A Wii U demo for Slipstream with 3D graphics rendered using a custom Wii U engine.
- We Are Outdated - A follow-up from the previous Wii U demo which additionally has framebuffer readback and other framebuffer effects.
- Super Mario 64 Port - A port of Super Mario 64 to the Wii U showing general GX2 usage.
- GTA3 Wii U port - A port of GTA3 to the Wii U that unfortunately got DMCA'd, although the source code is probably still somewhere online.
- angle - A work-in-progress port of ANGLE which brings OpenGL ES support to the Wii U. This contains a lot of GX2 code and could help with porting OpenGL code.
- rio - A game development framework for the Wii U, although it doesn't use CafeGLSL yet.
- ... probably more!
