count mesh triangles

[Flo]

how do i easily find out (during irrlicht runtime) how many triangles a specific mesh has?

[Boogle]

You could get a TriangleSelector for the mesh (smgr->createTriangleSelector(mesh,node)), then call selector->getTriangleCount(). Or you could read the source code of CTriangleSelector to see how it generates the triangle list, and copy that method to get your count.

momentary i make a meshbuffer and get the triangle count with getIndexCount(); ... but i don't know if this is right o.o

but now, i'll try your variant


----
edit: another prob:
i've got the indices pointer with getIndices();, but how do i get the indices themselves so i can do something like that o.o?

Code: Select all

for(i=0;i<indexcount;i++){
	triangle[i].indices[0] = >insert index i*3 here<;
	triangle[i].indices[1] = >insert index i*3+1 here<;
	triangle[i].indices[2] = >insert index i*3+2 here<;
}

Code: Select all

u16* Indices = myMesh->getMeshBuffer (0)->getIndices ();

Triangle count is actually indices size / 3.

ok, thx

but i'm still stuck on the other problem
