                                mesh.vertices = [[0,0,0],[1,1,0],[0,0,-1]]
                                mesh.coords = [[0.0,0.0],[1.0,1.0],[0.0,0.0]]
                                mesh.traingles = [[0,1,2]]
                                mesh.computeNormals()
                                mesh.compile()

)

Creates a vertex Buffer for example: this.addVertexBuffer('normals', 'gl_Normal');

Parameters:

  • name String

    Name of buffer

  • attribute String

    gl name

checkRepeat

()

Check if there are two vertices in the same place( useful to recognize bad import)
