Detailed Description
A cylinder (3 dimensions)
Constructor & Destructor Documentation
|
inline |
Constructor for cylinder.
- Parameters
-
radius The radius of the cylinder length The length of the cylinder axpt The central axial point of the cylinder (equidistant from both ends) axis The axial direction of the cylinder
Member Function Documentation
Computes the gradient of the SDF.
- Parameters
-
pt Point at which to compute the gradient
- Returns
- the gradient
References MADNESS_EXCEPTION.

inline |
Computes the normal distance.
This SDF naively uses contours, and should be improved before serious usage.
- Parameters
-
pt Point at which to compute the distance from the surface
- Returns
- The signed distance from the surface
