| transformation | This matrix is allowed to contain a translation and a rotation |
| scale | Apply a uniform scaling as well |
| virtual void nvidia::apex::DestructibleAssetAuthoring::applyTransformation | ( | const PxMat44 & | transformation | ) | [pure virtual] |

| ) | [pure virtual] |
Builds a new ExplicitHierarchicalMesh from an array of triangles, externally provided by the user. Note: setRootMesh and setCoreMesh may be implemented as follows: setRootMesh(x) <-> buildExplicitHierarchicalMesh( getExplicitHierarchicalMesh(), x) setCoreMesh(x) <-> buildExplicitHierarchicalMesh( getCoreExplicitHierarchicalMesh(), x)
| hMesh | new ExplicitHierarchicalMesh |
| meshTriangles | pointer to array of ExplicitRenderTriangles which make up the mesh |
| meshTriangleCount | the size of the meshTriangles array |
| submeshData | pointer to array of ExplicitSubmeshData, describing the submeshes |
| submeshCount | the size of the submeshData array |
| meshPartition | if not NULL, an array of size meshPartitionCount, giving the end elements of contiguous subsets of meshTriangles. If meshPartition is NULL, one partition is assumed. When there is one partition, these triangles become the level 0 part. When there is more than one partition, these triangles become level 1 parts, while the union of the parts will be the level 0 part. |
| meshPartitionCount | if meshPartition is not NULL, this is the size of the meshPartition array. |
| parentIndices | if not NULL, the parent indices for each chunk (corresponding to a partition in the mesh partition). |
| parentIndexCount | the size of the parentIndices array. This does not need to match meshPartitionCount. If a mesh partition has an index beyond the end of parentIndices, then the parentIndex is considered to be 0. Therefore, if parentIndexCount = 0, all parents are 0 and so all chunks created will be depth 1. This will cause a depth 0 chunk to be created that is the aggregate of the depth 1 chunks. If parentIndexCount > 0, then the depth-0 chunk must have a parentIndex of -1. To reproduce the effect of the old parameter 'firstPartitionIsDepthZero' = true, set parentIndices to the address of a int32_t containing the value -1, and set parentIndexCount = 1. To reproduce the effect of the old parameter 'firstPartitionIsDepthZero' = false, set parentIndexCount = 0. Note: if parent indices are given, the first one must be -1, and *only* that index may be negative. That is, there may be only one depth-0 mesh and it must be the first mesh. |
| virtual uint32_t nvidia::apex::DestructibleAssetAuthoring::buildSliceMesh | ( | const ExplicitRenderTriangle *& | mesh, |
| const FractureTools::NoiseParameters & | noiseParameters, | ||
| const PxPlane & | slicePlane, | ||
| uint32_t | randomSeed | ||
| ) | [pure virtual] |
Builds a mesh used for slice fracturing, given the noise parameters and random seed. This function is mostly intended for visualization - to give the user a "typical" slice surface used for fracturing.
| virtual void nvidia::apex::DestructibleAssetAuthoring::cacheChunkOverlapsUpToDepth | ( | int32_t | depth = -1 | ) | [pure virtual] |
Ensures that the asset has chunk overlap information cached up to the given depth. If depth < 0 (as it is by default), the depth will be taken to be the supportDepth given in the asset's destructibleParameters. It is ok to pass in a depth greater than any chunk depth in the asset.
| virtual bool nvidia::apex::DestructibleAssetAuthoring::calculateCutoutUVMapping | ( | PxMat33 & | mapping, |
| const nvidia::ExplicitRenderTriangle & | triangle | ||
| ) | [pure virtual] |
Calculate the mapping between a cutout fracture map and a given triangle. The result is a 3 by 3 matrix M composed by an affine transformation and a rotation, we can get the 3-D projection for a texture coordinate pair (u,v) with such a formula: (x,y,z) = M*PxVec3(u,v,1)
| mapping | resulted mapping, composed by an affine transformation and a rotation |
| triangle | triangle |
| virtual bool nvidia::apex::DestructibleAssetAuthoring::calculateCutoutUVMapping | ( | PxMat33 & | mapping, |
| const PxVec3 & | targetDirection | ||
| ) | [pure virtual] |
Uses the passed-in target direction to find the best triangle in the root mesh with normal near the given targetDirection. If triangles exist with normals within one degree of the given target direction, then one with the greatest area of such triangles is used. Otherwise, the triangle with normal closest to the given target direction is used. The resulting triangle is used to calculate a UV mapping as in the function calculateCutoutUVMapping (above).
The assumption is that there exists a single mapping for all triangles on a specified face, for this feature to be useful.

| bool | keepCachedFlag = false |
||
| ) | [pure virtual] |
Clears the chunk overlap cache.
| depth | Depth to be cleared. -1 for all depths. |
| keepCachedFlag | If the flag is set, the depth is considered to be cached even if the overlaps list is empty. |

| meshTriangleCount | the size of the meshTriangles array |

| submeshCount | the size of the submeshData array |
| meshPartition | if not NULL, an array of size meshPartitionCount, giving the end elements of contiguous subsets of meshTriangles. If meshPartition is NULL, one partition is assumed.

| meshPartitionCount | if meshPartition is not NULL, this is the size of the meshPartition array. |
| parentIndices | if not NULL, the parent indices for each chunk (corresponding to a partition in the mesh partition). |
| parentIndexCount | the size of the parentIndices array. This does not need to match meshPartitionCount. If a mesh partition has an index beyond the end of parentIndices, then the parentIndex is considered to be 0. Therefore, if parentIndexCount = 0, all parents are 0 and so all chunks created will be depth 1. This will cause a depth 0 chunk to be created that is the aggregate of the depth 1 chunks. If parentIndexCount > 0, then the depth-0 chunk must have a parentIndex of -1. To reproduce the effect of the old parameter 'firstPartitionIsDepthZero' = true, set parentIndices to the address of a int32_t containing the value -1, and set parentIndexCount = 1. To reproduce the effect of the old parameter 'firstPartitionIsDepthZero' = false, set parentIndexCount = 0. Note: if parent indices are given, the first one must be -1, and *only* that index may be negative. That is, there may be only one depth-0 mesh and it must be the first mesh. |

If cellColorCount is less than siteCount, the cell colors will cycle. That is, site N gets cellColor[NcellColorCount]. |
| cellColorCount | the number of cell colors (the length of cellColors array) |
| bounds | defines an axis-aligned bounding box which clips the visualization, since some cells extend to infinity |
| cellIndex | if this is a valid index (cellIndex < siteCount), then only the cell corresponding to sites[cellIndex] will be drawn. Otherwise, all cells will be drawn. |
