Not quite sure if this is the right section. I downloaded POVRAY today ( http://www.povray.org) in the ongoing quest for the perfect page turn POVRay is something I used to play with years ago. Anyhow I worked out how to place an image map onto an object in the ray tracer and animate this. At the moment I've just mapped onto a torus - which I know can be done in other ways. My goal is to map to more useful or interesting shapes - say a flag or page or similar. Here's what I have so far using VMS 10 and POVRAY 3.7 rc3: [wmvvideo]http://muvipix.com/cpg/albums/userpics/10215/torus_map.wmv[/wmvvideo] Basic technique (deep breath) - export video as a series of images to use as "image maps" on POVRAY with the frame number for each frame then export back out a series of images to import as an image series into Vegas. If I get something more useful I'll come back with detailed instructions. You could potentially use this to do some of the fancy 3d compositing that after effects manages - although it would be a lot more manual.

Wow - that's wild! Not sure where I'd ever use it.

Not sure I follow the details .. but very cool looking.

OK - this is not quite the same thing but it's using the same tools. A small title animation using POVRay. It's not that clear on the video but the text is made of Orange glass with a soft shadow including simulated caustics. [wmvvideo]http://muvipix.com/cpg/albums/userpics/10215/muvipix_text%7E0.wmv[/wmvvideo] I think there's potential in this program. I've got some more seroius 3d stuff that I'm going to try. Anyhow - here's the source POV file for the title above. - Code: Select all
#include "colors.inc" #include "textures.inc" global_settings { photons { count 100000 autostop 0 jitter .4 } } camera { location <0, 0, -6> look_at <0, 0, 0> } plane { z,1 pigment { colour White } } light_source { <2.5-clock*4, 3.5-clock*7, -6+clock*2> colour White area_light <0.25, 0, 0>, <0, 0.25, 0>, 5, 5 adaptive 1 jitter photons { refraction on reflection on } }
text { ttf "cyrvetic.ttf" "Muvipix.com" .3, 0 translate x*-2.5 texture { Orange_Glass } photons{ target reflection on refraction on collect on } }
And this in the accompanying ini file use to render it. - Code: Select all
; Persistence Of Vision raytracer version 3.5 ini file. Antialias=On Antialias_Threshold=0.3 Antialias_Depth=3
Input_File_Name=text.pov
Output_File_Name=muvipix
Initial_Frame=0 Final_Frame=89
Initial_Clock=0 Final_Clock=1

I like the sparkle to the glass. Is this a stand alone program?

Oh, I'll bet you could have all KINDS of fun with that program! Very cool!

Yes, it's stand alone - although there are lots of support programs. I've never really played with animation with this before - I think there's a lot of potential with titles. Because it's a Ray Tracer it does things like glass and mirrors and shadows very well. Here's the "hall of fame" of user created images. http://hof.povray.org/

Here's another slightly higher resolution example. Shows a bit more detail. I've also tweaked the font, colour and camera movement slightly. (the ivdeo is actually 640x480 - but I can;t make it appear in the post - Help Ron?). Download for a better look in the meantime. [wmvvideo1]http://muvipix.com/cpg/albums/userpics/10215/muvipix_text_2.wmv[/wmvvideo1] And the .pov file: - Code: Select all
#include "colors.inc" #include "textures.inc" global_settings { photons { count 100000 autostop 0 jitter .4 } } camera { location <0, 0, -6+clock/2> look_at <0, 0, 0> } plane { z,1 pigment { colour White } } light_source { <3.5-clock*6, 5-clock*11, -6+clock*2> colour White area_light <0.25, 0, 0>, <0, 0.25, 0>, 5, 5 adaptive 1 jitter photons { refraction on reflection on } }
text { ttf "JOKERMAN.TTF" "Muvipix.com" .3, 0 translate x*-3.15 texture { NBglass pigment{ gradient x color_map { [0.00 color rgbf <1,0,0,0.8>] [1 color rgbf <0,.25,1,0.8> ] } scale 6.5 translate -3.15 } } photons{ target reflection on refraction on collect on } }

OK - next attempt. [wmvvideo1]http://muvipix.com/cpg/albums/userpics/10215/POV_Video.wmv[/wmvvideo1] This is a scene using POVRay and three imported videos from the background collections. Not quite as I'd hoped but reasonably pleased with the results.
