Detailed Description

Surface Shader class.

You might want to take at look at the Surface shader chapter for usage instructions

Constructor & Destructor Documentation

SurfaceShader()

oe::render::SurfaceShader::SurfaceShader	(	const std::string &	source_code,
		const std::string &	name = ""
	)

Create a new shader instance.

Parameters

source_code	Surface shader source code, check the documentation for the inputs/outputs
name	Name of the shader (will be used in error messages)

Member Function Documentation

setDepthFunctionName()

void oe::render::SurfaceShader::setDepthFunctionName ( const std::string &  name )

inline

Set a custom function to use for getting alpha.

Parameters

name	Name of the function in your surface shader to run when in depth mode

Note

The function definition must be like void name_parameter_value(in SurfaceInput surface_input, inout float alpha)
