Unigine::NodePivot Class

This class adds a pivot node that can serve as a pivot point for its children and allows for easy control over their transformation. It has two matrices: one sets the basis of rotation (the pivot point transformation matrix), and another one describes local transformation for children nodes relative to the pivot point.

static NodePivotPtr create()

Creates a pivot node (with the pivot and local transformation matrices equal to mat4_identity).

Ptr<NodePivot> cast(const Ptr<Node> & node)

Casts a NodePivot out of the Node instance.

Arguments

• const Ptr<Node> & node - Pointer to Node.

Return value

Pointer to NodePivot.

void setLocalTransform(const Math::mat4 & transform)

Sets a matrix that controls local transformations of children nodes.

Arguments

• const Math::mat4 & transform - Local transformation matrix.

Math::mat4 getLocalTransform()

Returns the current matrix used to control local transformations of the child nodes.

Return value

Local transformation matrix.

void setPivotTransform(const Math::mat4 & transform)

Sets a matrix that controls the basis of rotation of the child nodes (the pivot point transformation matrix).

Arguments

• const Math::mat4 & transform - Pivot transformation matrix.

Math::mat4 getPivotTransform()

Returns the current transformation matrix used to control the basis of rotation of the child nodes (the pivot point transformation matrix).

Return value

Local transformation matrix.
