Detailed Description

tessellate parametric functions

This class tessellates parametric functions. The user must specify how many points in the parametric coordinate directions are required (i.e., the resolution), and the mode to use to generate scalars.

Thanks:
Andrew Maclean a.maclean@cas.edu.au for creating and contributing the class.

Member Enumeration Documentation

enum vtkParametricFunctionSource::SCALAR_MODE
 

Enumerate the supported scalar generation modes.

 SCALAR_NONE,
      (default) scalars are not generated. SCALAR_U, the scalar is set to
      the u-value. SCALAR_V, the scalar is set to the v-value. SCALAR_U0,
      the scalar is set to 1 if u = (u_max - u_min)/2 = u_avg, 0 otherwise.
      SCALAR_V0, the scalar is set to 1 if v = (v_max - v_min)/2 = v_avg, 0
      otherwise. SCALAR_U0V0, the scalar is set to 1 if u == u_avg, 2 if v
      == v_avg, 3 if u = u_avg && v = v_avg, 0 otherwise. SCALAR_MODULUS,
      the scalar is set to (sqrt(u*u+v*v)), this is measured relative to
      (u_avg,v_avg). SCALAR_PHASE, the scalar is set to (atan2(v,u)) (in
      degrees, 0 to 360), this is measured relative to (u_avg,v_avg).
      SCALAR_QUADRANT, the scalar is set to 1, 2, 3 or 4 depending upon the
      quadrant of the point (u,v). SCALAR_X, the scalar is set to the
      x-value. SCALAR_Y, the scalar is set to the y-value. SCALAR_Z, the
      scalar is set to the z-value. SCALAR_DISTANCE, the scalar is set to
      (sqrt(x*x+y*y+z*z)). I.e. distance from the origin.
      SCALAR_USER_DEFINED, the scalar is set to the value returned from
      EvaluateScalar().

SCALAR_U0, the scalar is set to 1 if u = (u_max - u_min)/2 = u_avg, 0 otherwise. SCALAR_V0, the scalar is set to 1 if v = (v_max - v_min)/2 = v_avg, 0 otherwise. SCALAR_U0V0, the scalar is set to 1 if u == u_avg, 2 if v == v_avg, 3 if u = u_avg && v = v_avg, 0 otherwise. SCALAR_MODULUS, the scalar is set to (sqrt(u*u+v*v)), this is measured relative to (u_avg,v_avg). SCALAR_PHASE, the scalar is set to (atan2(v,u)) (in degrees, 0 to 360), this is measured relative to (u_avg,v_avg). SCALAR_QUADRANT, the scalar is set to 1, 2, 3 or 4 depending upon the quadrant of the point (u,v). SCALAR_X, the scalar is set to the x-value. SCALAR_Y, the scalar is set to the y-value. SCALAR_Z, the scalar is set to the z-value. SCALAR_DISTANCE, the scalar is set to (sqrt(x*x+y*y+z*z)). I.e. distance from the origin. SCALAR_FUNCTION_DEFINED, the scalar is set to the value returned from EvaluateScalar().
