Detailed Description


In general, each curve and surface has a parametric function that describes its minimal natural definition.

To represent other circles and planes, the following items are sequentially applied to each curve and surface (except for NURBS curves and NURBS surfaces):

  1. Trim
  2. Parametric transformation (an affine function)
  3. Cartesian transformation

For example, the following equation shows the application of these modifications:

PointOnCurve = CartesianTransformation( F(CoefA * Parameter + CoefB) )

Where the equation components have the following characteristics:
