Title: Buf3D Multiresolution Technology (video)
Post by: buf3d on November 12, 2013, 08:57:56 PM
A new video about the technology implemented in Buf3D is available in

     http://www.youtube.com/watch?v=1NrAW5SeQg0

This video demonstrates the use of the GPU to display massive multiresolution models without CPU cost (does not require regeneration of triangles)
A single call to glDrawArraysInstanced enables progressive display of multiple instances of the same geometry, each with the desired level of detail.

The models used for the demo are:
* Bunny.ply (stanford - Triangles 69K)
* Happy.ply (standord - 1M triangles)
* Xyzrgb_dragon.ply (stanford - 7.2 M triangles)
* Lucy.ply (stanford - 28M triangles!)

All the models are generated and displayed in a low end notebook AMD-1215B (only 80 shaders)

I'm interested this demo. :) Please do you put here or PM (private message) download for Windows?

My specs are i5-2500K@4.5GHz, 2x4GB RAM DDR3@1600MHz, GeForce GTX 480 and Windows XP x86 SP3/7 x64 SP1.

Hello nuninho1980

I'm evaluating the option of leaving an executable demo.
For this  I need to disable some unnecessary options.
Briefly hope to have a "correct" version.

It will be interesting to see his performance in a powerful graphics card.
Currently the Radeon-6310 generates 54M triangles/s (demo Geeks3D instances)
But in this graphics card, Geometry Shaders drastically reduces performance, so by this multiresolution technlogy only 20M triangles/s are generated, but with the desired level of detail :)

Is you are interesting, another (very technical) video are available on
