Detailed Description This is the state interface to access the internals of a thing mesh object and factory (both). Member Function Documentation void iThingState::CheckFrustum ( iFrustumView * fview, iMovable * movable ) [pure virtual]   Check frustum visibility on this thing. First initialize the 2D culler cube. @@ Does this belong here? void iThingState::CompressVertices ( ) [pure virtual]   Compress the vertex table so that all nearly identical vertices are compressed. The polygons in the set are automatically adapted. This function can be called at any time in the creation of the object and it can be called multiple time but it normally only makes sense to call this function after you have finished adding all polygons and all vertices. Note that calling this function will make the camera vertex array invalid. void iThingState::DeleteVertex ( int idx ) [pure virtual]   Delete a vertex. Warning this will invalidate all polygons that use vertices after this vertex because their vertex indices will no longer be ok. void iThingState::DeleteVertices ( int from, int to ) [pure virtual]   Delete a range of vertices (inclusive). Warning this will invalidate all polygons that use vertices after these vertices because their vertex indices will no longer be ok. This function does bounds-checking so an easy way to delete all vertices is DeleteVertices(0,1000000000). void * iThingState::GetPrivateObject ( ) [pure virtual]   @ UGLY. @ void iThingState::ReplaceMaterials ( iMaterialList * materials, const char * prefix ) [pure virtual]   Replace the materials in this thing with new materials that are prefixed by some name. For example, if a polygon in this thing uses a material 'blabla' and the prefix is 'pref' then the new material that will be used is called 'pref_blabla'. If that material cannot be found then the original material will be used. void iThingState::SetMovingOption ( int opt ) [pure virtual]   Control how this thing will be moved. There are currently three options. CS_THING_MOVE_NEVER: this option is set for a thing that cannot move at all. In this case the movable will be ignored and only hard transforms can be used to move a thing with this flag. This setting is both efficient for memory (object space coordinates are equal to world space coordinates so only one array is kept) and render speed (only the camera transform is needed). This option is very useful for static geometry like walls. This option is default. CS_THING_MOVE_OCCASIONAL: this option is set for a thing that is movable but doesn't move all the time usually. Setting this option means that the world space vertices will be cached (taking up more memory that way) but the coordinates will be recalculated only at rendertime (and cached at that time). This option has the same speed efficiency as MOVE_NEVER when the object doesn't move but more memory is used as all the vertices are duplicated. Use this option for geometry that is not too big (in number of vertices) and only moves occasionally like doors of elevators. CS_THING_MOVE_OFTEN: this option is set for a thing that moves very often (i.e. almost every frame). Setting this option means that the object->world and camera transformations will be combined at render time. It has the same memory efficiency as MOVE_NEVER but the transforms need to be combined every frame (if the object is visible). Use this option for geometry that moves a lot. Also very useful for objects that often move and have lots of vertices since in that case combining the transforms ones is a lot more efficient than doing two transforms on every vertex.
