Member Function Documentation

◆ AddColor()

void FACET::AddColor ( const SGCOLOR & aColor )

Add the given RGB color to the internal list.

For per-face coloring only a single color needs to be specified. For a per-vertex coloring the color must be specified for each vertex.

◆ AddVertex()

void FACET::AddVertex	(	WRLVEC3F &	aVertex,
		int	aIndex
	)

Add the vertex and its associated index to the internal list of polygon vertices.

◆ CalcFaceNormal()

float FACET::CalcFaceNormal ( )

Calculate the normal to the facet assuming a CCW orientation and perform the calculation of the angle weighted vertex normals.

Returns: is the max. magnitude of any component of the normal or zero if there is a fault or the normal has already been calculated.

◆ CalcVertexNormal()

void FACET::CalcVertexNormal	(	int	aIndex,

	)

Calculate the weighted normal for the given vertex.

Parameters

aIndex	is the VRML file's Vertex Index for the vertex to be processed.
aFacetList	is the list of all faces which share this vertex.
