GLUT --> openGL ES help!!!

[Nitrex88]

Ok I'm trying to learn fluid simulation and the best I could find was using the navier stokes equations for fluid simulation in gaming. A very in depth article about this was created by Jos Stam. The article can be found here...

Along with this article (on Jos Stam's website) I found a link to a full C project written in openGL and GLUT creating this fluid simulation. You can download it yourself from his website if you want. I went ahead and packaged it in an xcode project already and you can see it here...

www.nitrexpro.com/GLUT_Fluid_Example.zip

Just build and go to run. To add density you right click and hold and then click with left mouse button to apply forces. You can also hit "V" to see a line version of the velocity.

Anyway I'm trying to port this to iPhone which does not have GLUT and i am having some trouble. I know it can be done and a video using this exact code ported to iPhone can be seen here...

Therefore i know it can be done but i cannot figure out the transition. If any of you are up for the challenge and have some spare time can you try to make the changes in code so it will run on iPhone. I dont need the velocity view with the lines and stuff, just the stuff with adding density and pushing it around (you will see). If not can you perhaps give me some pointers on what needs to be changed and where to look or start. This forum has been super helpful so hopefully someone can solve this problem too. Thanks a ton!

I could be wrong, but I don't believe that video shows the code actually running on an iPhone. Based on the author's comments below the video, it sounds like he was using the iPhone only for the accelerometer and multitouch inputs to the application, which is running on another machine.

I don't think it's possible AFAIK. There is the Glut|ES project but I haven't been able to get it to compile all the way through. I get some conflicts with data types. Try Mesa instead.

Hey I was able to somewhat successful do what i was trying too but i got some new issues that i posted in a new thread (only because the question is different from the one im really asking in this thread). Go check it out here...

Can you guys help some more now that I have the code in objective-C working on iPhone?

Hi Nick,

Is there any chance that GLUT_Fluid_Example.zip or other similar source is still available for download somewhere? I've been trying to implement the navier-stokes solver, and could use the help.

Any help would be greatly appreciated.
Cheers,
Dan.
