Include

#include "Chaos/ConvexFlattenedArrayStructureData.h"

Syntax

template<typename T_INDEX, typename T_OFFSETINDEX>
class TConvexFlattenedArrayStructureData : public Chaos::Legacy::FConvexFlattenedArrayStructureData

Remarks

A container for the convex structure data arrays. This is templated on the index type required, which needs to be large enough to hold the max of the number of vertices or planes on the convex.

T_INDEX: the type used to index into the convex vertices and planes array (in the outer convex). Must be able to contain max(NumPlanes, NumVerts).

T_OFFSETINDEX: the type used to index the flattened array of indices. Must be able to contain Max(NumPlanes*AverageVertsPerPlane)

Variables

Name Description

Public variable

TArray< FIndex ...

 

PlaneVertices

A flattened ragged array. For each plane: the set of vertex indices that form the corners of the face in counter-clockwise order.

Public variable

TArray< TPair< ...

 

PlaneVerticesOffsetCount

Array of [offset, count] for each plane that gives the set of indices in the PlaneVertices flattened array.

Public variable

TArray< FIndex ...

 

VertexPlanes

A flattened ragged array. For each vertex: the set of plane indices that use the vertex.

Public variable

TArray< TPair< ...

 

VertexPlanesOffsetCount

Array of [offset, count] for each vertex that gives the set of indices in the VertexPlanes flattened array.
