Some months ago I was working on a conversion of an OpenGL Quake 1 model viewer I did years ago, it must have been 2000 or 2001 or something, to Papervision3D. The overall conversion went pretty smooth because all of the difficult stuff I already did when I was building the OpenGL version and the code was documented pretty well.
When doing the conversion there was one problem I had at the time and that was the texturing. I just couldn’t get the texturing to work correctly with Papervision3D. I read the Papervision3D documentation and searched the web from top to bottom and inside out to find an example of the correct way to apply a texture to a Face3D object. At one point I just gave up and the code started to collect dust on my hard drive.
Until today. For a commercial project I’m currently working on I’m going to use Papervision3D and since I could spend paid hours on figuring out what the problem was with this code it seemed the right opportunity to dust off the Quake 1 model viewer code and fix this issue once and for all. And behold, after a day of debugging and bending my brain over and backwards, I seemed to have fixed the problem.
Basically, and I will not bore you with the details, I figured out that the Papervision3D documentation wasn’t that clear since the Face3D class constructor didn’t expected an array of {x,y} objects for the UV coordinates but an array of NumberUV objects. Second, the UV coordinates had to be given in percentage, something I lucky remembered from my OpenGL programming days.
So, there you go. You can checkout the Quake 1 model viewer here (might take a couple of seconds to load) and please let me know what you think…
