Detailed Description

Off is a simple geometry file format storing positions, indices, and optionally colors.

Function Documentation

template<int N, typename FT , typename IT , typename CT , typename Interface >

void Euclid::read_off	(	const std::string &	filename,
		std::vector< FT > &	positions,
		std::vector< CT > *	vcolors,
		std::vector< IT > *	findices,
		std::vector< CT > *	fcolors
	)

Off file can store positions, indices, vertex colors and face colors. Note that index count can vary per face, but it's asumed to be fixed for all faces by this reader. Also note that off file format can store edge indices, which is often 0, thus omitted by this reader.

Template Parameters

N	Number of vertices per face.
FT	Type of floating point value.
IT	Type of index value.
CT	Type of color value.
Interface	User should never specify the type for it.

Parameters

filename	Input file name.
positions	Vertex positions.
vcolors	Vertex colors, including r, g, b, a. Use nullptr if you don't want to read them.
findices	Face indices. Use nullptr if you don't want to read them.
fcolors	Face colors, including r, g, b, a. Use nullptr if you don't want to read them.

Note

Proper overloading functions are implemented so that it's not necessary to provide template parameters even if nullptr is used.
