Shader programs are written in Cg/HLSL language, by embedding “snippets” in the shader text, somewhere inside the Pass command. The rest of this page will assume shaders that do not interact with Unity lights (e.g. For some examples, take a look at Vertex and Fragment Shader Examples. OpenGL Core has the following minimum requirements: Mac OS X 10.8 (OpenGL 3.2), MacOSX 10.9 (OpenGL 3.2 to 4.1) Windows with NVIDIA since 2006 (GeForce 8), AMD since 2006 (Radeon HD 2000), Intel since 2012 (HD 4000 / IvyBridge) (OpenGL 3.2 to OpenGL 4.5) Linux (OpenGL 3.2 to OpenGL 4. If you want to write shaders that interact with lighting, take a look at Surface Shaders documentation. Here we’ll call the low-level hardware shaders shader programs. Take a look at shader tutorial for a basic introduction. As such, OpenGL has many language bindings, some of the most noteworthy being the JavaScript binding WebGL (API, based on OpenGL ES 2.0, for 3D rendering. The actual programmable shaders - like vertex and fragment programs - are just a part of the whole ShaderLab’s “shader” concept.

They describe properties that are displayed in the Material Inspector, contain multiple shader implementations for different graphics hardware, configure fixed function hardware state and so on. To add support for OpenGL ES 2. ETCRGB4 is a part of OpenGL ES 2.0 and is supported by all OpenGL ES. ShaderLab shaders encompass more than just “hardware shaders”. OpenGL ES 2.0 Unity doesn’t include OpenGL ES 2.0 in its built-in set of graphics APIs for Android by default. This is the default Texture format for Android projects in Unity.
