intersect

intersect(dragConstraints: {}, viewport: IViewportApi, node: ITreeNode, ray: IRay): { matrix: mat4; dragAnchor?: IDragAnchor; dragConstraint?: IDragConstraint }

Intersect the provided drag constraints with the ray provided. Returns a matrix with the transformation of the node. The selection of the drag constraint works by taking the one with the closest distance to the ray.

It returns the dragConstraints that were used and the matrix that was calculated. If no dragConstraint was used, this entry is left empty.

Parameters
- dragConstraints: {}
  - [key: string]: IDragConstraint
- viewport: IViewportApi
- node: ITreeNode
- ray: IRay
Returns { matrix: mat4; dragAnchor?: IDragAnchor; dragConstraint?: IDragConstraint }
- matrix: mat4
- Optional dragAnchor?: IDragAnchor
- Optional dragConstraint?: IDragConstraint

setup

setup(dragConstraints: {}, viewport: IViewportApi, node: ITreeNode, ray: IRay, intersection: IIntersection, previousDragMatrix: mat4): { matrix: mat4; dragAnchor?: IDragAnchor; dragConstraint?: IDragConstraint }

Setup the provided drag constraints. The drag origin is set here and a first computation of the matrix is done.

It returns the dragConstraints that were used and the matrix that was calculated. If no dragConstraint was used, this entry is left empty.

Parameters
- dragConstraints: {}
  - [key: string]: IDragConstraint
- viewport: IViewportApi
- node: ITreeNode
- ray: IRay
- intersection: IIntersection
- previousDragMatrix: mat4
Returns { matrix: mat4; dragAnchor?: IDragAnchor; dragConstraint?: IDragConstraint }
- matrix: mat4
- Optional dragAnchor?: IDragAnchor
- Optional dragConstraint?: IDragConstraint
