UVMeshable

A bit of programming

UVMeshable objects are shapes that provides the UVMeshable interface:

class UVMeshable
{
public:
  virtual void evalVertex( Vector3d& r, const DBL u, const DBL v )const;
  virtual void evalNormal( Vector3d& r, const DBL u, const DBL v )const;
  virtual void minUV( Vector2d& r )const;
  virtual void maxUV( Vector2d& r )const;
};

Which shapes are UVMeshable

So far the following shapes are UVMeshable:

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 )

Turning UVMeshable into mesh

#include "NurbsMesh.inc"
#declare UResolution = 92;
#declare VResolution = 92;
mesh {
     UVMeshable( UVMeshableObject, UResolution, VResolution )
     }
