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 232 of file GA_AttributeTransformer.h.

GA_Detail& GA_AttributeTransformer::getDetail ( ) const
inline

Return the bound detail.

Definition at line 236 of file GA_AttributeTransformer.h.

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

Return the handle to the individual attribute.

Definition at line 234 of file GA_AttributeTransformer.h.

bool GA_AttributeTransformer::hasDouble ( ) const
inline

Check whether any attributes are single- or double-precision

Definition at line 268 of file GA_AttributeTransformer.h.

bool GA_AttributeTransformer::hasSingle ( ) const
inline

Check whether any attributes are single- or double-precision

Definition at line 267 of file GA_AttributeTransformer.h.

bool GA_AttributeTransformer::needInverse ( ) const
inline

Check whether any attributes require the inverse/quaternion transforms

Definition at line 261 of file GA_AttributeTransformer.h.

bool GA_AttributeTransformer::needQuaternion ( ) const
inline

Check whether any attributes require the inverse/quaternion transforms

Definition at line 262 of file GA_AttributeTransformer.h.

void GA_AttributeTransformer::transform ( const GA_Range &  range,
Transform< fpreal32 > &  m 
) const

Perform the transformation on all attributes.

Note
The Transform reference is non-const. The methods are mostly thread safe (provided threads access unique pages of data). However, since the Transform object is non-const, the Transform should not be shared across threads.
void GA_AttributeTransformer::transform ( const GA_Range &  range,
Transform< fpreal64 > &  m 
) const

Perform the transformation on all attributes.

Note
The Transform reference is non-const. The methods are mostly thread safe (provided threads access unique pages of data). However, since the Transform object is non-const, the Transform should not be shared across threads.
void GA_AttributeTransformer::transform ( const GA_Range &  range,
Transform< fpreal32 > &  m32,
Transform< fpreal64 > &  m64 
) const

Perform the transformation on all attributes.

Note
The Transform reference is non-const. The methods are mostly thread safe (provided threads access unique pages of data). However, since the Transform object is non-const, the Transform should not be shared across threads.
void GA_AttributeTransformer::transform ( GA_Offset  offset,
Transform< fpreal32 > &  m 
) const

Perform the transformation on all attributes.

Note

void GA_AttributeTransformer::transform ( GA_Offset  offset,

) const

Perform the transformation on all attributes.

void GA_AttributeTransformer::transform ( GA_Offset  offset,
Transform< fpreal32 > &  m32,
Transform< fpreal64 > &  m64 
) const

Perform the transformation on all attributes.
