Detailed Description

A filter creating a normal-map/height-map from a height map image.

Constructor & Destructor Documentation

template<typename Extractor >

oglplus::images::NormalMap::NormalMap	(	const Image &	input,
		Extractor	extractor = Extractor()
	)

Creates a normal-map from the input height-map image.

Parameters

input	the height-map image to be filtered
extractor	the height map color component extractor (by default the RED component of the image is used as the height-map value used in normal-map calculation).

Member Function Documentation

GLsizei oglplus::images::Image::Dimension ( std::size_t  i ) const

inherited

Returns the i-th dimension of the image.
