Dotsceneoctree and OgreOpcode

[jacmoe]

I am toying with the idea of creating a DotsceneOctreeCollisionShape in OgreOpcode.
I found the following functions:

Code: Select all

int DotSceneManager::GetNumMeshes( char* name ); 
float* DotSceneManager::GetVerticesPtr( char* name, int MeshIndex  ); 
int*  DotSceneManager::GetIndexPtr( char* name, int MeshIndex ); 
int DotSceneManager::GetNumVertices( char* name, int MeshIndex  ); 
int DotSceneManager::GetNumIndex( char* name, int MeshIndex );

If GetNumMeshes returns the number of meshes in the octree, I can generate all needed collision shapes for the level easily.

But how do I know which *mesh* the camera is currently in?

I suppose I could use something like this for each DotsceneOctree collisionShape:

Code: Select all

camera->isVisible( node->_getWorldAABB() ) 

Isn't there a more efficient way?
