Detailed Description

Generic warping node.

This class implements the generic warping node model. In contrast to most other nodes, warpings are always unary nodes.

Constructor & Destructor Documentation

◆ TreeWarp()

TreeWarp::TreeWarp ( TreeNode * node = nullptr )

explicit

Create a warping node.

Parameters

node	Child node.

◆ ~TreeWarp()

TreeWarp::~TreeWarp ( )

virtual

Recursively destroys the structure.

Implicitly calls TreeUnary::~TreeUnary().

Member Function Documentation

◆ GetMaterial()

virtual Color TreeWarp::GetMaterial	(	const Vector &	,
		const Vector &	= Vector::Null ) const

pure virtual

Gets the color of a node at a point.

This function returns a default black material.

Reimplemented from TreeNode.

Implemented in TreeFrame, TreeRotate, TreeScale, TreeTaper, TreeTranslate, and TreeTwist.
