Development of a Tracker node that monitors avatar position and orientation on a 2D plane. Improved functionality for collision detection between objects and subsequent behaviour specification. Normal specification is available for lighting in VRML but not in relation to object distance specification. This function would also enhance maintaining relative positions of objects. Gravity node Development of a modifiable Gravity node.
Gravity is a force that influences the behaviour of objects in the real world.
At present NavigationInfo tracks movement along a surface in WALK mode but does not allow definition of the forces imposed by individual objects. Example applications Gravity could also be used to move an avatar around a sphere by specifying a point force for gravity. Gravity forces of a surface should be accessible to drop an avatar at a 2D location on the surface. 2D object linking Many geographic phenomena are reported as 2D vector coordinates. The projection of these 2D coordinates onto the 3D surface would be useful.
