A mesh is specified by a grid of `columns' x `rows' vertices. Each grid cell represents a surface element with a vertex position. Additionally, at each position the normal, 4 texture coordinates and a vertex color can be supplied.
It is allowed to construct a mesh with an empty vertex iterator; in this case, columns or rows must be also zero, otherwise an assertion will occur.

| void VRS::Mesh::setVertexIterator | ( | unsigned int | columns, | |
| unsigned int | rows, | |||
| Iterator< Vector > * | iter | |||
| ) |
The mesh vertex data is specified by 'setVertexIterator'. This argument iterator must not be empty. The Mesh assumes that the other iterators (from PolygonSet) represent `columns' x `rows' data values. All iterators are expected to provide the values row by row. For standard OpenGL/VRS cullface settings (counter clockwise), vertices should be given from left to right and bottom to top, i.e.:
7 8 9
4 5 6
1 2 3
| virtual void VRS::Mesh::setType | ( | PolygonSet::PrimitiveType | primitiveType | ) | [virtual] |
the primitive type of a mesh is PolygonSet::TriangleStrip, and you cannot change that.
Reimplemented from VRS::PolygonSet.

This method constructs a normal iterator calculating surface normals for the mesh based on the current vertex iterator. If the mesh surface is conceptually closed, i.e., x borders and/or y borders are attached, the wrapping is set to 'true'.
| unsigned int VRS::Mesh::columns | ( | ) | const |
Return the number of mesh columns.
| unsigned int VRS::Mesh::rows | ( | ) | const |
Return the number of mesh rows.
