P4_ripplingShader
« on: November 15, 2016, 01:32:08 PM »
Project 4 was somewhat open ended, we were asked to make a shader that simulates animated ripples and incorporate it with a short segment of live action footage.

For my project in particular, I decided to use a glass door and then composite a 3D plane (with the ripple shader)  in its place.  I will post pictures ASAP, the ones I have are over the forum limit at the moment.

Sounds like a great idea. I can't wait to see it.

Here's a still of my ripple so far.  I have it animating how I like because it degrades as it gets bigger over time, but I'm still having a bit trouble getting the sine wave-based ripples to work.  At this point I might have to scrap that gem.

**Not pictured, I was able to let the user pick how many ripples are created and randomize the position for each one.  I can upload a picture of that later.

**Color is subject to change.

Here's another still, this time showing my randomly placed ripples that the last (purple) picture didn't show.

The colors are subject to change because this is a normal pass, which I'll use to distort my live action plate in order to fake a refraction in Nuke.

Still no working sine waves.

Good job getting multiple ripples in at the same time. Can't wait to see your refraction.

I really like your process shots. What you showed in class today is far off from where you were. Make sure you upload your final so that future students can benefit.

I think your colorgrade down the center of your final was a little strong but your concept and execution were very strong.
