Detailed Description

This class is the base class for all absolute transform nodes.

An absolute transformation provides an own and explicit transformation independent form parent nodes.

Member Enumeration Documentation

◆ TransformationType

enum Ocean::Rendering::AbsoluteTransform::TransformationType

Defines different transformation types.

Enumerator

Member Function Documentation

◆ headUpRelativePosition()

virtual Vector2 Ocean::Rendering::AbsoluteTransform::headUpRelativePosition ( ) const

virtual

Returns the relative screen position of the head-up node.

The default value is (0.5, 0.5)

Returns: Relative screen position, with range [0.0, 1.0] for each axis, -1.0 neglects this definition

Exceptions

NotSupportedException Is thrown if this function is not supported

See also: setHeadUpRelativePosition().

Reimplemented in Ocean::Rendering::GLESceneGraph::GLESAbsoluteTransform.

◆ setHeadUpRelativePosition()

virtual bool Ocean::Rendering::AbsoluteTransform::setHeadUpRelativePosition ( const Vector2 & position )

virtual

Sets the relative screen position of the head-up node.

Parameters

position Relative screen position, with range [0.0, 1.0] for each axis, -1.0 neglects this definition

Returns: True, if succeeded

Exceptions

NotSupportedException Is thrown if this function is not supported

See also: headUpRelativePosition().

Reimplemented in Ocean::Rendering::GLESceneGraph::GLESAbsoluteTransform.

◆ setTransformation()

virtual void Ocean::Rendering::AbsoluteTransform::setTransformation ( const HomogenousMatrix4 & absolute_T_children )

pure virtual

Sets an additional transformation which is applied on top of the absolute transformation.
