k, here is what I have so far. The only bit of tech that is different in this demo compared to my other random projects is the fluid kernal function. So I guess my question is what is a laplacian used for? What about the gradient functions I read about everywhere? Are they related to other features ...

I seriously love fluid dynamics. I've read as many articles as I can over the last 12 months.... but I still don't have a stable SPH routine yet.. I'll let you offer your expertise if you like :) I was getting an error when trying to compile with the latest version of FB... had to add this line to t...

This is great!

I'm looking forward to the optimized version.

I'm inspired to try something similar.

Shader support in FreeBASIC would be very cool.

Maybe the glew library.

Some tips that I've used over time to help me stay productive at the PC. 1) Pen and paper. As things come up, write them down. You free up mental resources for the task at hand this way. For example, if I'm working on some rotation code, and I remember that I've got to fix the texture coords for the...

Very nice Rel.

I've tried to handle collisions a few times with varying degrees of success.

Thanks for the links and code examples.

Hey Joshy,

I think the English term you are looking for is: "The volume of a dome".

Normally a dome is just half a sphere, which is easy to calculate the volume of. But for other domes, that aren't half spheres you'll need the following:

Absolutely love it h4tt3n. I'm a sucker for graphics code, and specifically fluid dynamics at the moment. I've only breifly looked at the code, but a couple of things that may help: - Better broadphase collision detection (I see it on the TODO) - Do you need the SQR? Or can you just test on the squa...

How about we forget about adding a heap of new problems onto the library and fix the existing problems first? There are still unresolved tickets in the tracker. Spend more effort on ways to resolve those before we worry about adding new tickets to the tracker. I'd like to try my hand at fixing some...
