Platform based Shaders

The API allows the creation of Shader objects from within Lua. The ‘Shader.new()’ constructor takes five arguments:

• The vertex shader - filename (no extension) or code within a string.
• The fragment shader - filename (no extension) or code within a string.
• A set of numerical flags or 0 if none.
• An array of uniforms/constants descriptors.
• An array of attributes descriptors.

Gideros will search the assets for a file with the supplied name, automatically adding the extension relevant for the target platform: .glsl for OpenGL, .cso or .hlsl for DirectX. The Flag 'Shader.FLAG_FROM_CODE' can be used to let Gideros know that the string is actually Shader code, not contained within a file.
