How to do 3D feature detection?

04 March 2015 - 10:04 AM

I was wondering if anyone knows of any companies or products that can do 3D feature detection.  I’m looking for any 3rd party software that I could license to do the heavy lifting for me.


As an example of what I’m looking for see the image below.  The 3D shape is made up of triangles.  The information that I have about the shape includes the locations of all the vertices, the faces for each triangle and their normals. What I would like to be able to do is detect interesting features about this 3D shape such as:

·         Where is the center location of the circular hole on the top face

·         Where is the midpoint of any “straight” edge on this shape




Do you know of any software tools that might be able to help me?

Is it possible to do Batch Rendering with 3D skeletal animation data?

22 November 2014 - 05:27 PM

I've implemented a batch rendering technique that is described in detail here:http://www.gamedev.net/page/resources/_/technical/opengl/opengl-batch-rendering-r3900

I'd like to extend it now to support 3D skeletal animation data, but I'm not sure what is the best way to do that so that the bone transformation can happen on the GPU rather than on the CPU. The Batches as they are defined right now depend on a transform matrix but that means that if I try to render a human, each limb would go into its own Batch, which means I would not get any performance gain by using the BatchManager as described in the article above.

Can someone suggest how to do batch rendering that works with 3D skeletal animation data?  Is that even possible?

Just wondering if there is anyone here who is/will be getting the PrioVR suit?


I'm getting one myself and plan on using it to do some motion capture for games and films.

Need help building HTPC

04 June 2014 - 06:43 PM

I've been using an old WinXP pc as my home theatre PC but now I'd like to upgrade to something smaller and quieter.  I use this PC for some light gaming and now that you can stream steam games over the home network I'm thinking I want some small hardware to run linux, xbmc and steam.
Any suggestions on hardware I can buy?  I'd like to spend no more than $300 for the new HTPC, so I've been looking at Zotac ZBox's.  Can anyone suggestion other good hardware?
