Detailed Description
Hemisphere-disk skeletal primitive.
This complex skeleton is defined as the Minkowski sum between a hemisphere and a disc.
Example of how to code a hemisphere-disc:
TreeNode *halfsphere=new TreeHemisphereDisc(Vector(0.0),Vector(1,-1,1),4.0,1.0,new BlendCubic(2.0,1.0));
TreeHemisphereDisc(const Vector &, const Vector &, const double &, const double &, BlendCompact *)
Create a hemisphere-disc element.

Constructor & Destructor Documentation
◆ TreeHemisphereDisc()
| TreeHemisphereDisc::TreeHemisphereDisc | ( | const Vector & | c, |
| const Vector & | a, | ||
| const double & | r, | ||
| const double & | s, | ||
| BlendCompact * | blend | ||
| ) |
Create a hemisphere-disc element.
The total radius of the shape is defined as the sum of the radius of the disc and the radius of the half-sphere.
- Parameters
-
c Center of the hemisphere. a Axis of the hemisphere (will be normalized internally). r Radius of the disc. s Radius of the half sphere. blend Falloff function.
