END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

Hi, I have posted a Win32 binary that requires an nVidia CUDA capable card (G92 chip or G200 chip) such as a GTX260, nVidia 8800GT or similar cards and a fairly recent driver (CUDA 2.3 supported). It renders the fractal in real-time and morphs through powers 1 (sphere) until power 10 (mandel-ball) and all the way back.

Press the space bar to start the animation.
Press "f" to go full screen (but this requires some horse power in your card).
Hit q or ESC to exit the demo.

Read the instructions in the DOS box to get information about the other key commands.

My frame rate in the VGA (640x480) sized window is between 30 and 10 during the animation on an nVidia 9600 GSO, depending on how big the fractal currently appears. The fractal is phong shaded, but in the future I intend to apply better materials (this thing is raytraced, after all).

To download the binary (or the source code which is in a post above) you will need an nVidia forums login, which is a free sign-up and can be quickly obtained.

i sent my registration details for the nvidia forums last weekend, still nothing at the end of this friday  :

still no email, and i can't contact anyone since you need to be logged in 

it's cool that you can now do RTRT using nvidia's own libraries! how have you found working with optix?

It's quite simple to get started based on the SDK samples. It offers a low level SDK for working with rays. Based on Optix you can implement various types of renderers with different feature sets or rendering and lighting techniques. The tutorials are quite accessible.

Just a shame that it's not yet meant for the consumer level GPUs (yet!). Getting it to run there is possible, but requires some hacks.
