Member Function Documentation

getShader() [1/2]

virtual u32 IShaderSource::getShader ( const std::string & name, const ShaderConstants & input_const, video::E_MATERIAL_TYPE base_mat, IShaderUniformSetterRC * setter_cb = nullptr )

pure virtual

Generates or gets a shader.

Note that the input constants are not for passing the entire world into the shader. Use IShaderConstantSetter to handle user settings.

Parameters

name	name of the shader (directory on disk)
input_const	primary key constants for this shader
base_mat	base material to use
setter_cb	additional uniform setter to use

Returns

shader ID

Note

base_material only controls alpha behavior

Implemented in ShaderSource.

Helper: Generates or gets a shader for common, general use.

Parameters

name	name of the shader
blendAlpha	enable alpha blending for this material?

Returns

shader ID
