Detailed Description

Rotations in a frame node.

Rotation nodes change the whole geometry of their children nodes.

Example of how to code a rotation node:

TreeNode *element=new TreeNodeEdge(Vector(1,0,-1),Vector(1,0,1),new BlendCubic(2.0,1.0));

TreeNode *framed=new TreeRotate(element,Matrix::Rotation(Vector(Math::Pi/6,0.0,0.0)));

BlendCubic

Normalized blending functions (1-r2)3.

Definition: blend.h:114

Math::Pi

static const double Pi

Matrix::Rotation

static Matrix Rotation(const Vector &)

TreeNode

The generic nodes with some pure virtual functions.

Definition: blobtree.h:27

TreeRotate::TreeRotate

TreeRotate(TreeNode *, const Matrix &=Matrix::Identity)

Creates a rotation node in the tree structure.

		const Vector &	v = `Vector::Null`
	)

explicit

Creates a rotation node in the tree structure.

Parameters

v	Vector of Euler rotation angles.

◆ TreeRotate() [3/3]

TreeRotate::TreeRotate	(	TreeNode *	node,
		const Vector &	a,
		const Vector &	b
	)

explicit

Create a rotation node in the tree structure given two vectors.

Parameters

◆ ~TreeRotate()

TreeRotate::~TreeRotate ( )

virtual

Destroy a frame node in the tree.

Implicitly calls the destructor TreeWarp::TreeWarp() that recursively destroys its child node.

Member Function Documentation

◆ Cut()

TreeNode * TreeRotate::Cut ( const Box & b ) const

virtual

Cuts the node to simplify its structure inside a box.

Parameters

b The box.

Implements TreeNode.

◆ GetMaterial()

Color TreeRotate::GetMaterial	(	const Vector &	p,
		const Vector &	n = `Vector::Null`
	)		const

virtual

Compute the texture parameters.

Transforms the point into the local frame, and compute the texture descending into the tree recursively.

Implements TreeWarp.

◆ Gradient()

Vector TreeRotate::Gradient ( const Vector & p ) const

virtual

Compute the gradient.

Returns the transformed gradient computed by the child node after framing the point into local space.

Parameters

p Point.

Reimplemented from TreeNode.

◆ Intensity()

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

virtual

Returns the intensity computed by the child node after transforming the point into local space.

Parameters

p Point.

Implements TreeNode.

◆ K() [1/4]

double TreeRotate::K ( const Box & b ) const

virtual

Computes the Lipschitz constant within an argument box.

Basically tests if the argument box intersects the box of the node, and returns the Lipchitz constant of the tree structure if intersection occurs.

Implements TreeNode.

◆ K() [2/4]

double TreeRotate::K ( const RayStep & raystep ) const

virtual

Computes the Lipschitz constant of the frame node intersecting a segment.

Parameters

raystep The segment.

Reimplemented from TreeNode.

◆ K() [3/4]

double TreeRotate::K ( const Segment & segment ) const

virtual

Computes the Lipschitz constant of the frame node intersecting a segment.

Parameters

segment The segment.

Reimplemented from TreeNode.

◆ K() [4/4]

double TreeRotate::K ( const Sphere & sphere ) const

virtual

Computes the Lipschitz constant of the frame node intersecting a sphere.

Parameters

sphere The sphere.

Reimplemented from TreeNode.

◆ Rotate()

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

virtual

Rotates the node in the BlobTree.

Instead of inserting a rotation node in the tree, simply updates the rotation matrix of the node.

Parameters

r	Rotation matrix.

Reimplemented from TreeNode.
