beginLineStrip()

void beginLineStrip

(

)

Send a line strip's worth of vertices.

Begin a strip, send as many vertices as you want, and then end the strip.

endLineStrip()

void endLineStrip

(

)

generate()

void generate	(	int	startIndex = 0,
		bool	addToState = true
	)

initGenerator()

void initGenerator

(

int

initialNum = 100

)

lineStripVertex() [1/2]

void lineStripVertex

(

const int32_t

pointIndex

)

Send a line strip's worth of vertices using indexed vertices.

NOTE: must be called after setupIndexedVertexArray().

Definition at line 83 of file SoTangentBundle.h.

lineStripVertex() [2/2]

void lineStripVertex

(

const SbVec3f &

point

)

Definition at line 67 of file SoTangentBundle.h.

set() [1/2]

void set	(	int32_t	numTangents,
		const SbVec3f *	tangents,
		SoTangentBindingElement::Binding	binding,
		int	startIndex = 0
	)

set() [2/2]

void set

(

SoTangentCache *

tc

)

setupApproxShapeSize()

void setupApproxShapeSize

(

int32_t

approxNumVertices

)

Resets the approximative number of vertices that we have to generate tangents for.

These correspond to the same parameters in the constructor, but allows setting them after creation.
Note: Must be called before first call to polygonVertex or triangle calls..

Definition at line 88 of file SoTangentBundle.h.

setupIndexedVertexArray()

void setupIndexedVertexArray

(

const SbVec3f *

pointArray

)

Specifies a pointer to the array of points that will be used in subsequent calls to polygonVertex(index) and triangle(index1,index2,index3).

Using this mode allows reusing vertices, avoiding data copy and increasing performance. IMPORTANT NOTE:

• This function should be called before any call to polygonVertex/triangle functions.
• The data should remain valid until generate() has ended.
• Once setupIndexedVertexArray has been called, only "by index" functions are valid.

~SoTangentBundle()

virtual ~SoTangentBundle ( )

virtual

Class: SoTangentBundle.

Bundle that allows shapes to deal with tangents and tangent bindings more easily. This class provides a fairly simple interface to tangent handling, including tangent generation.
