Detailed Description

cGenericArray implements an abstract class for describing geometrical elements composed of vertices.
Example of elements include points, segments, or triangles. Each element shall be composed on one or more vertices (point=1, segment=2, triangle=3).

void chai3d::cGenericArray::compress ( )

bool chai3d::cGenericArray::getAllocated ( const unsigned int a_index ) const

inline

Is the element passed by argument currently allocated.

Returns: true if the element is allocated, false otherwise.

virtual unsigned int chai3d::cGenericArray::getVertexIndex	(	const unsigned int	a_elementIndex,
		const unsigned int	a_vertexNumber
	)		const

inlinevirtual

This method returns the index number of a vertex for a selected element. The element is identified by passing its index number as argument. The vertex is selected by passing its vertex number. For a triangle. this number shall be 0,1, or 2.

Parameters

a_elementIndex	Index number of the element.
a_vertexNumber	Vertex number.

Returns: Index number to the requested vertex.

Reimplemented in chai3d::cTriangleArray, chai3d::cSegmentArray, and chai3d::cPointArray.

cVector3d chai3d::cGenericArray::getTexCoordAtPosition	(	const unsigned int	a_elementIndex,
		const cVector3d &	a_localPos
	)

inline

This method returns the texture coordinate at the nearest point on the element from an input location.

Parameters

a_elementIndex	Index number of selected element.
a_localPos	Location of point on element.

Returns: Interpolated texture coordinate at desired location.
