Point of View
Just a quick doodle type of thing I did t’other day, I think it’s pretty cool:
I’m rendering a 141 frame (5.64s) fluid simulation at the moment - it’s taking aaaaaaaaaaaaaaaaaaages!! On average it’s taking like 4 minutes per frame! Anyway I’ll probably post that up by tommorow.
As I mentioned before I’ve been trying to get this optical flow effect to work in Blender using the displace composite node. I tried it out on some real ‘live action’ footage (as opposed to the cube I used before). It didn’t really work that well - mainly because the shot contained some very dark spots where you couldn’t really make the effect out. Also I think the clip was too short, so you barely noticed the effect at all. I think I might try and make it work by looping some fire footage and duplicating it a lot of times. Another possibility is to use a development version of Blender, which has enhanced particle effect features (see the progress here), to use a technique called billboards, which means that you use particles to control a certain video, which in this case would be the looping fire footage. This would mean that I could have a controlled randomness to the fire footage. Unfortunately I’m having trouble getting the billboards to work without crashing Blender! Anyway, hopefully I should have a nice optical flow effect to show by… the end of the year!
