Detailed Description

Class to efficiently transform multiple attributes.

This class will transform attributes as efficiently as possible, depending on the attribute's properties. The transformer works on a single class of attributes (i.e. GA_ATTRIB_POINT).

Member Function Documentation

void GA_AttributeTransformer::addAttribute	(	GA_Attribute *	attrib,
		bool	keep_lengths = `false`
	)

Add a single transformable attributes to the handle list. When keep_length is set, normals and vectors will maintain their lengths under scaling.

void GA_AttributeTransformer::addAttributes ( bool keep_lengths = false )

Add all transformable attributes to the handle list. When keep_length is set, normals and vectors will maintain their lengths under scaling.

void GA_AttributeTransformer::addAttributes	(	const GA_AttributeFilter &	filter,
		bool	keep_lenghts = `false`
	)

Add a filtered selection of attributes to the handle list. The filter should filter out non-transforming attributes. When keep_length is set, normals and vectors will maintain their lengths under scaling.

void GA_AttributeTransformer::clearAttributes ( )

Clear the list of transformable attributes.

exint GA_AttributeTransformer::entries ( ) const

inline

Return the number of attributes which will be transformed.

Definition at line 234 of file GA_AttributeTransformer.h.

GA_Detail& GA_AttributeTransformer::getDetail ( ) const

inline

Return the bound detail.

Definition at line 238 of file GA_AttributeTransformer.h.

const Handle& GA_AttributeTransformer::getHandle ( exint i ) const

inline

Return the handle to the individual attribute.

Definition at line 236 of file GA_AttributeTransformer.h.

bool GA_AttributeTransformer::hasDouble ( ) const

inline

Check whether any attributes are single- or double-precision

Definition at line 270 of file GA_AttributeTransformer.h.

bool GA_AttributeTransformer::hasSingle ( ) const

inline

Check whether any attributes are single- or double-precision

Definition at line 269 of file GA_AttributeTransformer.h.

bool GA_AttributeTransformer::needInverse ( ) const

inline

Check whether any attributes require the inverse/quaternion transforms

Definition at line 263 of file GA_AttributeTransformer.h.

bool GA_AttributeTransformer::needQuaternion ( ) const

inline

Check whether any attributes require the inverse/quaternion transforms

Definition at line 264 of file GA_AttributeTransformer.h.
