r	Cylinder radius.
blend	Falloff function.

◆ TreeCylinder() [2/2]

TreeCylinder::TreeCylinder	(	const Vector &	a,
		const double &	h,
		const double &	r,
		BlendCompact *	blend
	)

Member Function Documentation

◆ Intensity()

double TreeCylinder::Intensity ( const Vector & p ) const

virtual

Computes the intensity at given point in space.

Parameters

p Point.

Reimplemented from TreeNormal.

◆ K()

double TreeCylinder::K ( const Ray & ray ) const

virtual

Returns a local Lipschitz constant along a ray.

Returns the Lipschitz constant of the element if argument ray intersects the element's bounding box.

Parameters

ray The ray.

Check the intersection with the box, then with the capsule.

Reimplemented from TreeElement.

◆ Rotate()

TreeNode * TreeCylinder::Rotate ( const Matrix & r )

virtual

Rotates a cylinder element.

Instead of inserting a rotation node in the tree, this member simply updates the vertices of the cylinder as well as its internal parameters.

Parameters

r	Rotation matrix.

Reimplemented from TreeNode.

◆ Translate()

TreeNode * TreeCylinder::Translate ( const Vector & t )

virtual

Translates a cylinder element.

Parameters

t	Translation vector.

Reimplemented from TreeNode.
