Finally the promised screenshot

SPH with symmetry

It’s not all that impressive to look at as I’ve restricted all the particles to 2d although it does use 3d calculations. I do this to help look for any issues in the code as I find it hard to spot errors in a 3d particle rendering.

This particular screenshot has 64000 particles that have been dropped into the box in a column formation and are now starting to slosh around at the bottom.

The unusual thing with regards to a CUDA implementation is that it is using symmetry in the interactions thereby decreasing the memory/processing load. I’ve still got more work to do but its showing a lot of promise in running superfast particle interaction simulations.

I’ve aso been doing a bit of work on my second version of my raytracer. I’ve once again stepped away from KD-trees and Octrees and am using a type of BVH, ray marching system. Screenshots once I have a decent scene rendered

In other news I’m now compiling all my new C++/CUDA code in 64bit with the CUDA 3.0 beta. Although I think putting in c++ object support into CUDA was a mistake the new version does produce decent code.

My little blog is officially one year old today!

Over the last year I’ve made many more posts than I was originally planning to make and judging by the number of subscribers and variety of institutions and people who visit it’s not entirely all rubbish, or so I like to tell myself.

Ongoing projects that will hopefully get completely or improved in the coming year are:

Thermal monitor - networking coming soon

More raytracing (of course) - linking PhysX to it (thanks to Timothy’s post here for inspiration) to improve on my rather primitive bouncing balls.

SPH and Lattice methods for fluid simulation

Sorting algorithms - I haven’t posted much on this lately but some decent results so far

Massive Data set processing.

Anything else that grabs my interest
