Introduction

Grouping nodes organize objects in an X3D world in various ways. There existe several grouping nodes that have different functions.

• Group and StaticGroup collect related nodes together. This way one can reuse it as a whole
• Transform is probably the most important node. It controls position, orientation and scale of its children
• Inline loads other X3D scenes
• LOD (level of detail) provides different levels of geometry quality according to the user's viewpoint
• Switch can be animated to select different children, one (or none) at a time
• Anchor allows to define URL links to another X3D scene or other page in a web browser
• Billboard allows to create a group whose geometry always faces the user
• Collision provides collision detection properties between child geometry and the camera.
