Hey,

I was just searching my name on the web and noticed that you used my thesis to figure out the BSP stuff. When I was learning the stuff, I found it particularly difficult to find information about this subject… so I’m glad it was helpful.

You can simply import the obj in prefab. When building the bsp tree, it’ll generate the awd for you.

Ok, so I think I will use Prefab to do it. It seems simpler. But is there a way to change my models format from .obj to .awd?

Elie: I don’t recommend it (it can take a while and you’d have to wait on every load), but here’s a quick rundown of how it’d work:

1) Load your obj as usual
2) Create a BSP tree builder by calling BSPBuilder.generateBuilder(…); with the options you like (it’ll return an object of type IBSPBuilder)
3) setup listeners on the returned builder (see class BSPBuildEvent)
4) call builder.build(mesh.geometry.faces);
5) on build complete: add the tree (builder.tree) to the stage using the usual addChild();

For multiple meshes, you’ll first have to “bake” their transformations in the vertices and place the faces in one array before passing them to the builder.

Hello, I am building a 3D scene using away3d. I am using .obj file format to load the models. Can you provide a tutorial on how to use the BSP feature without using prefab3d and using .obj models?

Dimumurray: It’s a bit hard to explain, but it’s the same for most systems using a pvs. Check out the info on leaks on the Valve Dev Community: http://developer.valvesoftware.com/wiki/Leak

Could you clarify what you mean by “…your model must be completely sealed”…

[...] important to note that away3d has spent a significant amount of time to optimize 3d away3d support Binary Space Partitioning. Hopefully in future versions of PreFab we can import .bsp maps that would truly be the cats meow! [...]
