Detailed Description

An array to handle indirect references (i.e. shared items)

This class takes two GT_DataArrays. The indirect array should be an array of integers which are used to perform indirect lookup into the shared data array. For example:

GT_DataArray        VertexList =  [ 1, 4, 2, 3 ]
GT_DataArray        &PointAttributes;
GT_DAIndirect       attribs(VertexList, PointAttributes);

This allows the point attributes to be referenced by vertex number.

Member Function Documentation

const char* GT_DAIndirect::className ( ) const

inlineoverridevirtual

Implements GT_DataArray.

Definition at line 58 of file GT_DAIndirect.h.

int64 GT_DAIndirect::getDataId ( ) const

overridevirtual

Return the "data id" associated with the data. The data ID will be incremented if the data is modified. An ID less than 0 indicates that the data ID should always be considered unique and will never be the same across evaluations. This data ID can be used to detect whether attribute data has changed in similar tesselations.

Reimplemented from GT_DataArray.

const GT_DataArrayHandle& GT_DAIndirect::getIndirect ( ) const

inline

Definition at line 73 of file GT_DAIndirect.h.

GT_Size GT_DAIndirect::getTotalArrayEntries ( ) const

inlineoverridevirtual

Total number of array elements if this is an array attribute. Sum of each entry's array length, as each entry's array length can vary.

Reimplemented from GT_DataArray.

static int GT_DAIndirect::getUnmapThreshold ( )

static

void GT_DAIndirect::init	(	const GT_DataArrayHandle &	indirect,
		const GT_DataArrayHandle &	data,
		bool	flatten_nested
	)

Initialize data from an indirect array of indices and a data array.

bool GT_DAIndirect::isValid ( ) const

inlineoverridevirtual

Data array is valid; can be sampled from.

Reimplemented from GT_DataArray.

Definition at line 60 of file GT_DAIndirect.h.

GT_Size GT_DAIndirect::itemSize ( GT_Offset ) const

Return the number of elements in the array for the given item.
