Hi all.
I'm currently working on a ROAM (Terrain optimisation) algo in Dirrector, but
Lingo seems to be realy slow with that kind of things.
Computing the ROAM BinTree is not realy a problem but when calling the
GenerateNormals et the Build command to create or refresh the mesh, I get a
200ms freeze in my script (per frame) (with about 1000 poly) ... arg !
The other problem is the CreateMesh function require the faces number when
called. And this number can't change. Unfortunatly, the ROAM algo don't give a
constant number of faces.
I tried many things but the only way I found is to Delete et Re-create the mesh
at each frame ... hugly ! ... and so slow.
Does anybody of you know an other way to create, handle and refresh a mesh
faster with director : may be by programming a Xtra.
I read in a previous post some comments about Virtools. Is this software's
script more efficient with the mesh handling. I studied a bit Virtools and saw
there is two way for programming it : the VSL script or the SDK by C++ DLLs.
But I'm not sure the user made DLLs can be linked and export to a Web based
movie.
Thank you for your help
Regards.
Candide
