file | ChangeBackground.h [code] |
| Efficient multi-threaded replacement of the background values in tree.
|
|
file | Clip.h [code] |
| Functions to clip a grid against a bounding box or against another grid's active voxel topology.
|
|
file | Composite.h [code] |
| Functions to efficiently perform various compositing operations on grids.
|
|
file | Dense.h [code] |
| This file defines a simple dense grid and efficient converters to and from VDB grids.
|
|
file | DenseSparseTools.h [code] |
|
file | Diagnostics.h [code] |
|
file | Filter.h [code] |
| Filtering of VDB volumes. Note that only the values in the grid are changed, not its topology! All operations can optionally be masked with another grid that acts as an alpha-mask.
|
|
file | GridOperators.h [code] |
| Applies an operator on an input grid to produce an output grid with the same topology but potentially different value type.
|
|
file | GridTransformer.h [code] |
|
file | Interpolation.h [code] |
|
file | LevelSetAdvect.h [code] |
| Hyperbolic advection of narrow-band level sets.
|
|
file | LevelSetFilter.h [code] |
| Performs various types of level set deformations with interface tracking. These unrestricted deformations include surface smoothing (e.g., Laplacian flow), filtering (e.g., mean value) and morphological operations (e.g., morphological opening). All these operations can optionally be masked with another grid that acts as an alpha-mask.
|
|
file | LevelSetFracture.h [code] |
| Divide volumes represented by level set grids into multiple, disjoint pieces by intersecting them with one or more "cutter" volumes, also represented by level sets.
|
|
file | LevelSetMeasure.h [code] |
|
file | LevelSetMorph.h [code] |
| Shape morphology of level sets. Morphing from a source narrow-band level sets to a target narrow-band level set.
|
|
file | LevelSetRebuild.h [code] |
|
file | LevelSetSphere.h [code] |
| Generate a narrow-band level set of sphere.
|
|
file | LevelSetTracker.h [code] |
| Performs multi-threaded interface tracking of narrow band level sets. This is the building-block for most level set computations that involve dynamic topology, e.g. advection.
|
|
file | LevelSetUtil.h [code] |
| Miscellaneous utilities that operate primarily or exclusively on level set grids.
|
|
file | MeshToVolume.h [code] |
|
file | Morphology.h [code] |
| Implementation of morphological dilation and erosion.
|
|
file | ParticlesToLevelSet.h [code] |
| This tool converts particles (with position, radius and velocity) into a signed distance field encoded as a narrow band level set. Optionally, arbitrary attributes on the particles can be transferred resulting in an additional attribute grid with the same topology as the level set grid.
|
|
file | PointAdvect.h [code] |
| Class PointAdvect advects points (with position) in a static velocity field.
|
|
file | PointIndexGrid.h [code] |
| Space-partitioning acceleration structure for points. Partitions the points into voxels to accelerate range and nearest neighbor searches.
|
|
file | PointPartitioner.h [code] |
| Multi-threaded space-partitioning scheme for points.
|
|
file | PointScatter.h [code] |
| We offer three differet algorithms (each in its own class) for scattering of point in active voxels:
|
|
file | Prune.h [code] |
| Defined various multi-threaded utility functions for trees.
|
|
file | RayIntersector.h [code] |
| Accelerated intersection of a ray with a narrow-band level set or a generic (e.g. density) volume. This will of course be useful for respectively surface and volume rendering.
|
|
file | RayTracer.h [code] |
| Defines two simple but multithreaded renders, a level-set ray tracer and a volume render. To support these renders we also define perspective and orthographic cameras (both designed to mimic a Houdini camera), a Film class and some rather naive shaders.
|
|
file | SignedFloodFill.h [code] |
| Propagates the sign of distance values from the active voxels in the narrow band to the inactive values outside the narrow band.
|
|
file | Statistics.h [code] |
| Functions to efficiently compute histograms, extremas (min/max) and statistics (mean, variance, etc.) of grid values.
|
|
file | ValueTransformer.h [code] |
|
file | VectorTransformer.h [code] |
