The primary motivation is moving +shaders to OpenGL languages on the fly. The developer deals with \"profiles\" +that represent various target languages, such as GLSL or ARB_*_program. + +This allows a developer to manage one set of shaders, presumably written in +Direct3D HLSL, and use them across multiple rendering backends. This also +means that the developer only has to worry about one (offline) compiler to +manage program complexity, while MojoShader itself deals with the reduced +complexity of the bytecode at runtime. + +MojoShader provides both a simple API to convert bytecode to various profiles, +and (optionally) basic glue to rendering APIs to abstract the management of +the shaders at runtime.") + (license license:zlib)))) |
