Class PlainTriMesh

  • public class PlainTriMesh
extends TriMesh

    a triangle mesh representation that maintains a list of simple triangles.

    This class is templated and can be setup with different types of triangle storage.
    Mainly this concerns single or double precision but also number of normals in each Triangle.
    Check out Triangle.hpp to get an idea of the different types.

    The PlainTriMesh can be used as follows
    // create trimesh PlainTriMesh<TriangleN1<float> > mesh; // add data mesh.add( TriangleN1<float>(v1,v2,v3) ); mesh.add( TriangleN1<float>(v1,v2,v3) ); mesh.add( TriangleN1<float>(v1,v2,v3) ); // and access the mesh TriangleN1<float> tri_index1 = mesh[1]; Vector3D<float> normal = mesh[2].getFaceNormal();

    To convert the plain trimesh to a more efficient mesh representation take a look at
    TriangleUtil::toIndexedTriMesh().
