void SIM_IndexField::addSmokeRepresentation ( const SIM_RootData root,
GU_Detail gdp 
) const

Adds a volume primitive version of our field to the given gdp.

bool SIM_IndexField::appearsToBeUnused ( ) const

True if we have a constant value. Ignores end conditions in determining this. Used as a rough guess that the field is unused.

Definition at line 143 of file SIM_IndexField.h.

GU_ConstDetailHandle SIM_IndexField::createSmokeRepresentation ( const SIM_RootData root) const

Creates a GDP with us as a Volume Primitive inside it.

void SIM_IndexField::getBBox ( UT_BoundingBox bbox) const

Controls the dimensions of where the field is properly defined in the field space.

UT_VoxelBorderType SIM_IndexField::getBorder ( ) const

Definition at line 63 of file SIM_IndexField.h.

UT_Vector3 SIM_IndexField::getCenter ( ) const
UT_Vector3 SIM_IndexField::getDivisions ( ) const

Calculate the size and divisions according to options such as 2d or equal sized voxels.

const SIM_RawIndexField* SIM_IndexField::getField ( ) const

Retrieve raw field.

Definition at line 132 of file SIM_IndexField.h.

exint SIM_IndexField::getMemorySizeSubclass ( ) const

Override this function to return an accurate representation of the amount of memory used by this piece of data. The size of subdata should not be included in this calculation.

Reimplemented from SIM_Data.

void SIM_IndexField::makeEqualSubclass ( const SIM_Data source)

myField aware copy constructor.

Reimplemented from SIM_Data.

void SIM_IndexField::matchField ( const SIM_ScalarField field)

Match this field to the given reference field. We will end up with the same size/divisions/twod/uniform, but not the same sampling pattern

void SIM_IndexField::resizeKeepData ( const UT_Vector3 size,
const UT_Vector3 center,
bool  keepdata,
const char *  address = 0,
int  port = -1 

Resizes our field keeping our field data. The final size will be an integer number of voxels matching our current voxel size. The final center will be an integer number of voxel offset from our current center. This allows us to do a perfect copy of the data.

void SIM_IndexField::saveSubclass ( std::ostream &  os) const

Saves our attributes, and our internal data if it has been set.

Reimplemented from SIM_Data.

void SIM_IndexField::setBorder ( UT_VoxelBorderType  border)
