openvdb::v1_1_0::tools::internal Namespace Reference

Classes
class	TileSampler
	A TileSampler wraps a grid sampler of another type (BoxSampler, QuadraticSampler, etc.), and for samples that fall within a given tile of the grid, it returns a cached tile value instead of accessing the grid. More...
struct	TileSampler< PointSampler, TreeT >
	For point sampling, tree traversal is less expensive than testing bounding box membership. More...
struct	TileSampler< StaggeredPointSampler, TreeT >
	For point sampling, tree traversal is less expensive than testing bounding box membership. More...
class	PointTransform
class	PrimCpy
class	FogVolumeOp
class	InteriorMaskOp
struct	Tolerance
class	MeshVoxelizer
	TBB class object to voxelize a mesh of triangles and/or quads into a collection of VDB grids, namely a square distance grid, closest primitive grid and a intersecting voxels grid (the voxels intersect the mesh). More...
class	ContourTracer
	TBB Class object that slices up the volume into 2D slices that can be processed in parallel and marks the exterior contour of disjoint voxel sets in each slice. More...
class	IntersectingVoxelSign
	TBB Class object that traversers all the intersecting voxels (defined by the intersectingVoxelsGrid) and potentially flips their sign, by comparing the 'closest point' directions of outside-marked and non-intersecting neighbouring voxel. More...
class	IntersectingVoxelCleaner
	TBB Class object that removes intersecting voxels that where set by rasterizing self-intersecting parts of the mesh. More...
class	ShellVoxelCleaner
	TBB Class object that removes non-intersecting voxels that where set by rasterizing self-intersecting parts of the mesh. More...
class	ExpandNB
	TBB Class object to expand the level-set narrow-band. More...

void openvdb::v1_1_0::tools::internal::propagateSign ( DistTreeT &  distTree, typename DistTreeT::template ValueConverter< bool >::Type &  intersectionTree, InterruptT *  interrupter = NULL  )

inline

Does a sparse iteration on the distance grid to find regions with inconsistent sign information. The surfaceTracer method is then used to resolve the sign inconsistency in these regions.

Parameters

distTree	signed distance field to operate on
intersectionTree	tree that defines the surface boundary for the surface tracer
interrupter	an object that implements the util::NullInterrupter interface

std::vector<typename GridType::Ptr> openvdb::v1_1_0::tools::internal::segment ( GridType &  grid, InterruptType *  interrupter = NULL  )

inline

Segmentation scheme, splits disjoint fragments into separate grids.

Note

This is a temporary solution and it will be replaced soon.

void openvdb::v1_1_0::tools::internal::surfaceTracer ( const Coord &  seed, DistTreeT &  distTree, typename DistTreeT::template ValueConverter< bool >::Type &  intersectionTree  )

inline

Surface tracing method that flips the sign of interior marked voxels, will not cross the boundary defined by the intersecting voxels.

Parameters

seed	the coordinates of a interior marked seed point
distTree	the distance field to operate on
intersectionTree	tree that defines the surface boundary
