OpenGL ES 1.1 isosurface (metaball) question

Hi Everyone,

I’ve been working on a prototype of a water drop simulation iPhone app which when held horizontally mimics a real liquid drop moving on the screen based on accelerometer input.

The iPhone specific stuff is not a problem, but i’m wondering if OpenGL is the correct approach to solving this problem - and if it is, are there any tutorials, docs I should read.

I just recently stumbled across:


and am wondering if i’m working towards the right direction. Is OpenGL even needed in this situation or would a more procedural CoreGraphics solution work? My concern is frame-rate of course.

thanks for any help - this discussion group is great!
