Detailed Description

A 3D object.

Introduction

SceneObject exists as a foundation for 3D objects in Torque. It provides the basic functionality for:

A scene graph (in the Zones and Portals sections), allowing efficient and robust rendering of the game scene.
Various helper functions, including functions to get bounding information and momentum/velocity.
Collision detection, as well as ray casting.
Lighting. SceneObjects can register lights both at lightmap generation time, and dynamic lights at runtime (for special effects, such as from flame or a projectile, or from an explosion).
Manipulating scene objects, for instance varying scale.

An Example

Melv May has written a most marvelous example object deriving from SceneObject. Unfortunately this page is too small to contain it.

See also:: http://www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=3217 for a copy of Melv's example.

Container Interface

When objects are searched, we go through all the zones and ask them for all of their objects. Because an object can exist in multiple zones, the container sequence key is set to the id of the current search. Then, while searching, we check to see if an object's sequence key is the same as the current search key. If it is, it will NOT be added to the list of returns since it has already been processed.

Public Member Functions

SceneObject ()

virtual ~SceneObject ()

virtual bool prepRenderImage (SceneState *state, const U32 stateKey, const U32 startZone, const bool modifyBaseZoneState=false)

If global bounds are set to be true, then the object is assumed to have an infinitely large bounding box for collision and rendering purposes.

Collision and transform related interface

The Render Transform is the interpolated transform with respect to the frame rate. The Render Transform will differ from the object transform because the simulation is updated in fixed intervals, which controls the object transform. The framerate is, most likely, higher than this rate, so that is why the render transform is interpolated and will differ slightly from the object transform.

The SceneGraph traversal is recursive and the traversal state of an object can be one of three things:

Pending - The object has not yet been examined for zone traversal.
Working - The object is currently having its zones traversed.
Done - The object has had all of its zones traversed or doesn't manage zones.

Note:
These states were formerly referred to as TraverseColor, with White, Black, and Gray; this was changed in Torque 1.2 by Pat "KillerBunny" Wilson. This code is only used internal to this class
