ConvexMeshShape collision not working properly.

[frcandela]

Hi,
I am having issues making ConvexMeshShape colliders collide properly and not overlap/go through each others.
I have put together a system to reproduce the issues.
Here are the steps :

• In the testbed, open ConvexMesh.cpp and generate the polygon vertex array using the following code:
  `
  openglframework::Vector3* vertices = new openglframework::Vector3[6];
  vertices[0] = {-2.992055, -1.803289, -0.496232};
  vertices[1] = {-2.992055, -1.803289, 0.496232};
  vertices[2] = {-2.992055, 1.803289, -0.496232};
  vertices[3] = {-2.992055, 1.803289, 0.496232};
  vertices[4] = {2.992055, -1.803289, 0.000000};
  vertices[5] = {2.992055, 1.803289, 0.000000};

    int* indices = new int[18];
    indices[0] = 0;  indices[1] = 1;  indices[2] = 3;  indices[3] = 2;
    indices[4] = 2;  indices[5] = 3;  indices[6] = 5;
    indices[7] = 4;  indices[8] = 1;  indices[9] = 0;
    indices[10] = 2; indices[11] = 5; indices[12] = 4; indices[13] = 0;
    indices[14] = 5; indices[15] = 3; indices[16] = 1; indices[17] = 4;
  
    rp3d::PolygonVertexArray::PolygonFace* faces = new rp3d::PolygonVertexArray::PolygonFace[5];
    faces[0] = {4,0};
    faces[1] = {3,4};
    faces[2] = {3,7};
    faces[3] = {4,10};
    faces[4] = {4,14};
  
    mPolygonVertexArray =
            new rp3d::PolygonVertexArray(6, vertices, sizeof(openglframework::Vector3),
                                         indices, sizeof(int),
                                         5, faces,
                                         rp3d::PolygonVertexArray::VertexDataType::VERTEX_FLOAT_TYPE,
                                         rp3d::PolygonVertexArray::IndexDataType::INDEX_INTEGER_TYPE);
  

`

• Set testbed/meshes/convexmesh.obj with the following data (same vertices and indices as the previous step)
  o Wedge
  v -2.992055 -1.803289 -0.496232
  v -2.992055 -1.803289 0.496232
  v -2.992055 1.803289 -0.496232
  v -2.992055 1.803289 0.496232
  v 2.992055 -1.803289 0.000000
  v 2.992055 1.803289 0.000000
  s 1
  f 1 2 4 3
  f 3 4 6
  f 5 2 1
  f 3 6 5 1
  f 6 4 2 5
• Set the NB_MESHES=50 in ConcaveMeshScene.h. Set the other collisions shapes numbers to zero
• Start the testbed, open the ConcaveMesh Scene
• play the simulation and observe the wedge convex shape overlapping with the terrain
