 # Scene Class Reference

 Last update: 16.07.2025 

A class for 3D visualization of a structure Additionally, it can display palettes and text annotations as well as rich text labels. Internally, a representation in terms of triangles only is used. Qt separation: This class contains no functionality relying on Qt classes. All methods using Qt classes are virtual and have no implementation, calling DYNARDO\_LOG\_WARN instead. Their implementation is done in SceneQt, part of the sos\_qt\_extensions module. Class [Scene](class_scene.xhtml "A class for 3D visualization of a structure Additionally, it can display palettes and text annotation...") is NO QObject, but SceneQt is. Instances of [Scene](class_scene.xhtml "A class for 3D visualization of a structure Additionally, it can display palettes and text annotation...") or SceneQt are created with application\_makeScene(), implemented in the sos\_qt\_extensions or sos\_noqt\_extensions module respectively.

A class for 3D visualization of a structure Additionally, it can display palettes and text annotations as well as rich text labels. Internally, a representation in terms of triangles only is used. Qt separation: This class contains no functionality relying on Qt classes. All methods using Qt classes are virtual and have no implementation, calling DYNARDO\_LOG\_WARN instead. Their implementation is done in SceneQt, part of the sos\_qt\_extensions module. Class [Scene](class_scene.xhtml "A class for 3D visualization of a structure Additionally, it can display palettes and text annotation...") is NO QObject, but SceneQt is. Instances of [Scene](class_scene.xhtml "A class for 3D visualization of a structure Additionally, it can display palettes and text annotation...") or SceneQt are created with application\_makeScene(), implemented in the sos\_qt\_extensions or sos\_noqt\_extensions module respectively.
