Detailed Description

how to determine the sign of distances from a mesh

The constants are static fields of this class. value holds the underlying value, so this can also hold values that aren't named constants.

Member Data Documentation

HoleWindingRule

final SignDetectionMode meshlib.SignDetectionMode.HoleWindingRule = new SignDetectionMode(4)

static

computes robust winding number generalization with support of holes and self-intersections in mesh, it is the slowest sign detection mode, but it CAN be accelerated with CUDA if this mode activated e.g. in OffsetParameters.fwn

OddCrossings

final SignDetectionMode meshlib.SignDetectionMode.OddCrossings = new SignDetectionMode(3)

static

a point is inside if the surface is crossed an odd number of times on the way from the point to infinity, triangle orientation is ignored (as InsideMeshRule.OddCrossings in makeInsideMeshVolume); for meshes with holes, the result depends on the ray direction (+X); signedDistanceToMesh casts a ray from every point, while the volume functions (e.g. meshToDistanceVolume) cast one ray per row of voxels, which is much faster; this mode does NOT have CUDA acceleration at this moment

OpenVDB

final SignDetectionMode meshlib.SignDetectionMode.OpenVDB = new SignDetectionMode(1)

static

sign detection from OpenVDB library, which is good and fast if input geometry is closed

ProjectionNormal

final SignDetectionMode meshlib.SignDetectionMode.ProjectionNormal = new SignDetectionMode(2)

static

the sign is determined based on pseudonormal in closest mesh point (unsafe in case of self-intersections)

Unsigned

final SignDetectionMode meshlib.SignDetectionMode.Unsigned = new SignDetectionMode(0)

static

unsigned distance, useful for bidirectional Shell offset

value

final int meshlib.SignDetectionMode.value

WindingRule

final SignDetectionMode meshlib.SignDetectionMode.WindingRule = new SignDetectionMode(3)

static

< old name of OddCrossings
