feature request: 64 bit meshbuffers, and another one...

I think Irrlicht should have 64 bit meshbuffers so that if you needed a really large object in some situation that had a lot of polygons you could have it. What I also think would be good (since 16 & 32 bit meshbuffers are faster) is to make it possible to switch the meshbuffers between
16, 32, and 64 bit when you create the scene node, like have in " addMeshSceneNode(); " an option specifying the bit depth of the meshbuffer.

u know that u can have meshes with as many polys as u want. just not in one single meshbuffer. i think some of the loader automaticly split meshes when they are to big. And btw when u have such big meshes i think ur framerate will most likely drop rapidly.

You need more than 4.3 billion vertices in a single meshbuffer?

Where can I download your test model?

Since 64bit consoles are pretty old nowadays, and current hw targets 256bit, I guess we shouldn't bother with 64bit meshbuffers, but go all the way. Maybe we could make a point with 512bit meshbuffers

Ah hah! He wants to update his visualisation of the entire IPv4 address space to IPv6!

I didn't know that 32 bit meshbuffers allowed you to have 4.3 billion polys

heh. But what about the switching of the meshbuffer bit depth?

Yeah, what about?

3dman, you should learn what 32 bit means exactly. Crank out your calculator and see what 2^32 gives you. Switching the meshbuffer depth would be pointless. Correct depth is selected based on how many vertices there are. Otherwise you would get a bunch of topics from newbies a la "I have 2 million polies and my 16 bit mesh buffer doesn't work. bug0rzz!1"
