Detailed Description

FractureVoronoiDesc

Descriptor for Voronoi decomposition fracturing.

Member Enumeration Documentation

enum FractureTools::FractureVoronoiDesc::NoiseMode

Enum describing creation of displacement maps.

Constructor & Destructor Documentation

FractureTools::FractureVoronoiDesc::FractureVoronoiDesc ( ) [inline]

Constructor sets defaults

Member Function Documentation

void FractureTools::FractureVoronoiDesc::setToDefault ( ) [inline]

Sets the default values:

siteCount = 0; sites = NULL; chunkIndices = NULL; faceNoise.setToDefault(); instanceChunks = false; useDisplacementMaps = false; noiseMode = NoiseWavePlane; minimumChunkSize = 0.0f; materialDesc.setToDefault();

Member Data Documentation

const uint32_t* FractureTools::FractureVoronoiDesc::chunkIndices

Array of chunk indices to associate with each site. If this pointer is NULL, then all sites will be used to split all chunks relevant to the splitting operation. Otherwise, the chunkIndices array must be of length siteCount.

NoiseParameters FractureTools::FractureVoronoiDesc::faceNoise

Describes the characteristics of the interior surfaces. If the noise is 0, the cutting surface will smooth. Otherwise, there will be some variation, or roughness, to the surface.

Note: this noise is applied only to the graphics of the chunks. The chunks' collision volumes AND the chunks' children (if fractured further) will NOT be affected by this noise.

bool FractureTools::FractureVoronoiDesc::instanceChunks

If instanceChunks is true, corresponding chunks in different destructible actors will be instanced.

nvidia::FractureMaterialDesc FractureTools::FractureVoronoiDesc::materialDesc

Material application descriptor used for each slice. Note: the U-direction and UV offset in the descriptor will be ignored - UV mapping is done in arbitrary orientation and translation on each chunk face.

float FractureTools::FractureVoronoiDesc::minimumChunkSize

Smallest size allowed for chunks, as measured by their bounding sphere diameters. The sizes are interpreted as fractions of the unfractured mesh's bounding sphere diameter. Chunks created by fracturing which are smaller than this limit will be removed. Note - this will leave holes at the given depth. Default = 0, which disables this feature.

unsigned FractureTools::FractureVoronoiDesc::noiseMode

The noise mode. If displacement maps are enabled, NoisePerlin3D will be used.

unsigned FractureTools::FractureVoronoiDesc::siteCount

Number of cell sites in the sites array. Must be positive.

const physx::PxVec3* FractureTools::FractureVoronoiDesc::sites

Array of cell sites. The length of this array is given by siteCount.

bool FractureTools::FractureVoronoiDesc::useDisplacementMaps

If true, slice geometry and noise will be stored in a separate displacement offset buffer.
