Detailed Description

Todo:

think about how to model blend functionality. subclass that provides blend func related state , in opaque case force opaque options?

Constructor & Destructor Documentation

webgl1es2_material()

gdk::webgl1es2_material::webgl1es2_material	(	shader_ptr_type	pShader,
		material::FaceCullingMode	aFaceCullingMode,
		material::render_mode	aRenderMode
	)

constructs a webgl1es2_material. non-shader pipeline state and uniform values are 0 constructed, given default values specified by the opengl standard however a shader must be provided at ctor time, since the pipeline cannot be invoked without first using a shader logically, a webgl1es2_material without a shader_program implies a pipeline without a programmable vertex shader stage nor a programmable fragment shader stage, which is not a valid pipeline

Member Function Documentation

setTexture()

virtual void gdk::webgl1es2_material::setTexture ( const std::string &  aName, texture_ptr_type  aTexturePointer  )

overridevirtual

assigns a texture to the material.

Note

note that this is passed by pointer, not value
