Detailed Description

AbsoluteTransform is a transform node that provides a 4x4 matrix that is used to position subgraphs in absolute coordinate frame. During the RecordTraversal the matrix is directly pushed to the State::modelviewMatrixStack stack without the normal multiplication. After the subgraph is traversed the matrix is popped from the State::modelviewMatrixStack.

Member Function Documentation

◆ clone()

ref_ptr< Object > vsg::AbsoluteTransform::clone ( const CopyOp & copyop = {}) const
inlineoverridevirtual

clone this object using CopyOp's duplicates map to decide whether to clone or to return the original object. The default clone(CopyOp&) implementation simply returns ref_ptr<> to this object rather attempt to clone.

Reimplemented from vsg::Object.

◆ compare()

int vsg::AbsoluteTransform::compare ( const Object & rhs) const
overridevirtual

compare two objects, return -1 if this object is less than rhs, return 0 if it's equal, return 1 if rhs is greater,

Reimplemented from vsg::Object.

◆ read()

void vsg::AbsoluteTransform::read ( Input & input)
overridevirtual

Reimplemented from vsg::Object.

◆ transform()

dmat4 vsg::AbsoluteTransform::transform ( const dmat4 & mv) const
inlineoverridevirtual

Return the transform matrix, multiplying local transform matrix against the matrix passed into the transform(..) method. Typically one pre multiplies local transform against the matrix passed in, which during a RecordTraversal will be the previous modelview matrix inherited from above.

Implements vsg::Transform.

◆ write()

void vsg::AbsoluteTransform::write ( Output & output) const
overridevirtual

Reimplemented from vsg::Object.
