Constructor Detail

Compiler

public Compiler(MaterialGraph materialGraph)

Parameters:

materialGraph - MaterialGraph to compile into GLSL shader code

See Also:

compile()

Compiler

public Compiler(MaterialGraph materialGraph,
                int shaderVersion)

Parameters:

materialGraph - MaterialGraph to compile into GLSL shader code

shaderVersion - GLSL version targeted (version numbering as defined by #version of the GLSL spec), or -1 for default
Note: the Compiler may increase the version number depending on the MaterialGraph requirements. However, at time of writing, none of the build-in GraphNode will requires more than the default GLSL version 110.

compile()
