Hi,
do you remember this?
I worked again on it and moved most of the work on the gpu.

Would be cool if could download this small benchmark and post the calculation times for the different calculation modis and you pc spec.

simply press 'c' to create a new tower, write down that calculation time, press 'm', press 'c' again, and so on.
Would be really cool. Btw, this is optimized for DualCore Cpus but it works also on single cores, and please close alls background programs to get correct numbers.
Oh and you need a graphic card with shadermodel3.0 support (Geforce6, Radeon X1000 and up).
A small screenshot to make you wet:


To make this post looking even more professional and scientific a pie chart for you:


[edit]
I forgot to mention you need the latest directx dlls (november2008?), you can find it somewhere on microsoft.com.

That seems to be some very well commented code :P

For those it doesn´t start, download the latest dx version here: http://www.microsoft.com/downloads/detai...;DisplayLang=en

cpu + density map on gpu: 23,675sec the result runs with about 55fps
gpu: 3,211sec but there are several faces missing and it runs with "only" 20fps
gpu + weld on cpu: 54,041sec runs also with about 20fps and is also missing faces...

It looks very cool :P
I am just missing some blur and disortion of the "clouds"

oh - this seems very cool
with cpu +density i get 5,151sec (and ca 70 fps)
with gpu 1,32 sec -> but only 20 fps
and a image like this:
same with gpu+weld on cpu (there it needs 12,185 sec ; 28 fps)

edit: o my specs are: Core 2 Duo E8500 3.8 Ghz (overclocked)
4gig RAM
GF 8800 GTS 512 MB (overoverclocked - with special coolingsystem XD )

Thx so far, there seems to be a problem with some gpus.
Please don't forget to mention your pc specifications.

That looks fantastic! Almost a game: Try to get up this tower, and find secret caves where you put items and hints for other gamers...

EDIT: Can't be of help, because my grafikcard doesn't support shader 3.0.

CPU Intel Q9300 QuadCore @ 2.50GhZ
GPU ATi Radeon HD 3870 X2

gpu
~25fps
2.039 seconds
Clutters

gpu + weld on cpu
30fps
3.716 seconds
Clutters

cpu + density map on gpu
89fps
6.205 seconds
No Clutters

These aren't the most exact as I have some background programs open.

I love this kind of stuff! Mathematical toys

You had to do a lot of things directly with directx, right? because 3dgs doesn't provide tools for actually create geometry.

Having same visual display as Revo
I see this on,
gpu + weld on cpu
gpu
Cpu: intel q6600 2.4 ghz,
Gpu: ATi HD3870

cpu + density map on gpu
127 fps
10.356 seconds

gpu + weld on cpu
28 fps
4,089 seconds calc

gpu
22 fps
1.041 sec calculation time


and as Inestical
but running plenty of background programs

Nvidia 9600GT (runing on Win7 Beta Drivers - i will switch to newest vista drivers and give it another try)

Q9300 quadcore at @ 2.50

screens:


EDIT: apperentally, i was not on latest win7 drivers, i will try with latest win7 and vista drivers

same problem as quadraxas
cpu + density map 9.181 secs >200fps
gpu 1.793 secs 60fps
gpu + weld on cpu 19.6 secs 40fps
