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.

Member Enumeration Documentation

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().

void vtkParametricFunctionSource::SetScalarModeToY ( void  )
inline

Get/Set the mode used for the scalar data. The options are: 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_FUNCTION_DEFINED, the scalar is set to the value returned from EvaluateScalar().
