exint SIM_RawIndexField::buildIndex ( const SIM_RawField surface,

Builds from a surface & collision field. -1 if inside collision, -2 if not in collision and not in surface, otherwise a unique number. Returns maximum index (which you can also get from getMaxIndex)

exint SIM_RawIndexField::buildPartitionedIndex ( const SIM_RawField surface,
const SIM_RawField collision 
)
exint SIM_RawIndexField::collapseClassIndices ( )

Given a set of connectivity classes, collapse into the minimal set and renumber from 0. myMaxIndex will be updated with the resulting maximum & the number of components returned.

exint SIM_RawIndexField::computeConnectedComponents ( const SIM_RawField surface)

Computes the connected components of the given field. Anything with a value < 0 will be considered "inside" and connected to each other. Voxels with a value >= 0 will be flagged as being in component -1. The maxIndex will store the number of connected components.

exint SIM_RawIndexField::computeConnectedComponents ( const SIM_RawIndexField idx)

Computes the connected components according to the given index values. Areas of -1, -2, and >=0 will be consdiered three different material types and connectivity computed respectively.

Returns the set of samples in this field which correspond to the given location & sampling pattern. ix, iy, and iz should be size 8. If you want the deltas for the sampling pattern, call with x, y, z zero and clamp to false.

UT_Vector3I SIM_RawIndexField::getVoxelRes ( ) const

Returns the resolution of the voxel grid that we are sampling. This is a count of voxels, so may differ for our different sampling methods.

void SIM_RawIndexField::getWorldOrigin ( int origx,

Consistently compute a world origin for what world space 0,0,0 would map to. A bit tricky as we want to avoid round off if we line up to 0.5... This is not necessarily 0,0,0.

int SIM_RawIndexField::getXRes ( ) const

Returns the actual number of samples in each resolution. Preferred over field()->getXRes() as it doesn't require a copy of the CE fields.

bool SIM_RawIndexField::isAligned ( const SIM_RawIndexField field) const

Returns true if the two fields are precisely aligned. This means that samples are matched so a given integer index into either field would give the same result.

bool SIM_RawIndexField::isAligned ( const SIM_RawField field) const
bool SIM_RawIndexField::isColocated ( const SIM_RawField field,
UT_Vector3I offset 
) const

Returns true if two fields have voxels aligned. They do not have to be of the same resolution or share origin. However, using the offset allows to access this field with index of the other field. i.e. field->indexToPos(index) == this->indexToPos(index + offset)

bool SIM_RawIndexField::isColocated ( const SIM_RawIndexField field,
UT_Vector3I offset 
) const
bool SIM_RawIndexField::isMatching ( const SIM_RawIndexField field) const

Returns true if the given field and this one match in terms of number of voxels and bounding box size. This means the voxel cells match - not necessarily the sample points!

int  y,
int  z

Returns true if the given x, y, z values lie inside the valid index.

void SIM_RawIndexField::makeConstant ( exint  cval)
