Geometric Shapes
   Overview
Basic Shapes
Shapes by macro + CSG
Shapes in "shapes3.inc"
Other Shapes by macros
3D text shapes

Other Shapes
  - blob
  - sphere_sweep
  - julia_fractal
  - Regulare Polyhedron
  ->Paraboloid, Hyperboloid
  - Polynomial equations
  - Cubic & Quartic shapes
  - Parametric shapes

Non CSG Shapes
height_field + HF macros
Isosurfaces
                                   

Paraboloid and Hyperboloid from the include file "shapes.inc"

Before you can use the following geometric shapes the according include file must be inserted in the scenery description file by:
#include "shapes.inc"

 

Paraboloids, in positive x direction)  
Paraboloid_X, Hyperboloid     (sadle, see left)
Paraboloid_Y      Hyperboloid_Y
Paraboloid_Z      (double cone in y direction, see in tne middle, and right turned by rotate<90,0,0>}
These are infinite surfaces which can be used in csg functions like "intersection" or "clipped_by" with finite shapes to get finite shapes of these kinds.
These regular geometric shapes are defined symetric to <0,0,0>. Sample for how to use them as "object" by:
object{ Paraboloid_Y
        texture{....}
        translate<...> }
