## Detailed Description

This class describes a convex mesh made of faces and vertices.

The faces are made of polygons (not only triangles).

## Member Function Documentation

## ◆ getBounds()

const AABB & ConvexMesh::getBounds | ( |  | ) | const

Return the bounds of the mesh in the x,y,z direction.

Returns
  The three mimimum bounds of the mesh in the x,y,z direction

## ◆ getCentroid()

RP3D_FORCE_INLINE const Vector3 & reactphysics3d::ConvexMesh::getCentroid | ( |  | ) | const

Return the centroid of the mesh.

Returns
  The centroid of the mesh

## ◆ getFaceNormal()

RP3D_FORCE_INLINE const Vector3 & reactphysics3d::ConvexMesh::getFaceNormal | ( | uint32 | faceIndex | ) | const

Return a face normal.

Parameters

  faceIndex | The index of a given face of the mesh
