Detailed Description
A box (3 dimensions)
- Note
- LIMIT – the 3 primary axes must be x, y, and z
Constructor & Destructor Documentation
◆ SDFBox()
Constructor for box.
- Parameters
-
length The lengths of the box center The center of the box
Member Function Documentation
◆ grad_sdf()
Computes the gradient of the SDF.
- Parameters
-
pt Point at which to compute the gradient
- Returns
- the gradient
References MADNESS_EXCEPTION.
◆ sdf()
|
inline |
Computes the normal distance.
This SDF naively uses contours, and should be improved before serious usage. If far from the corners, the SDF is easy (similar to a plane), and is essentially what's implemented.
- Parameters
-
pt Point at which to compute the distance from the surface
- Returns
- The signed distance from the surface
