UVMeshable
A bit of programming
UVMeshable objects are shapes that provides the UVMeshable interface:
class UVMeshable
{
public:
virtual void evalVertex( VECTOR r, const DBL u, const DBL v )const;
virtual void evalNormal( VECTOR r, const DBL u, const DBL v )const;
virtual void minUV( UV_VECT r )const;
virtual void maxUV( UV_VECT r )const;
};
Which shapes are UVMeshable
So far the following shapes are UVMeshable:
nurbs(see User:Le_Forgeron/nurbs)rational_bezier_patch(see User:Le_Forgeron/rational_bezier_patch)sphereas a proof of concept
Access to data of UVMeshable objects
- Returns the minimal uv-coordinates uv_min( UVMeshableObject )
- Returns the maximal uv-coordinates uv_max( UVMeshableObject )
- Returns the vertex vector that corresponds to the given uv-coordinates uv_vertex( UVMeshableObject, Ucoordinate, Vcoordinate )
- Returns the normal vector that corresponds to the given uv-coordinates uv_normal( UVMeshableObject, Ucoordinate, Vcoordinate )
