View Full Version : shader output to texture

11 November 2006, 11:52 PM
I'm trying to do some sort of terrain growing, using some displacement and noise texture, BUT:

the noise needs to be animated. I could animate the time, but then a problem arrises - if a certain place was displaced a lot (high alpha value from the noise), I can't have it go back down. Which means that it needs always to grow up.
Imagine pouring sand on a table... sort of

what i was thinking, was to add a different small ammount of value every frame to the existing noise, but i need to be able to save the texture every frame and then reuse it and add to it some new values and so on.

So does anyone know how can I dynamically save a texture with every render?

Or if you have a different idea on how it could work, I'll be really happy if you share it.
