Constructor & Destructor Documentation
◆ SDFClone()
Create a virtual clone ofthe sub-tree, and locate it at the argument frame.
This is equivalent to copying the sub-tree, adding a frame node on top of the copy and creating the union of the two sub-trees, but more memory efficient.
SDFNode* n; // Sub-tree
Frame frame(Matrix::Rotation(Vector(1.0 / Math::Sqrt2, 1.0 / Math::Sqrt2, 0.0)), Vector(0.0, 0.0, 4.0)); // Transformation
SDFNode* c = n->Copy(); // Copy sub-tree
static const double Sqrt2
static Matrix Rotation(const Vector &)
- Parameters
-
n Sub-tree. f Frame.
