Yes, and shave off about anywhere from 60% to 80% of our load if done right, lol.

ok, but are you re-arranging the 8 childnodes in a binary way or re-calculating everything with a partition plain -like BSP?

Take into account that the binary tree should be balanced in order to get an increase in performance.

It's like BSP, attempting to sucessively cut the data set in half.

Relax I'm doing a dirty test right now (yes, for a v4.02 release). Lost in thought has already confirmed a 7.25 ms speed on my optimized ray routine (before the trees I'm working on now).

New test ran with beta Matthew (nuclear glory) sent me are really close. Here are the averages per cast out of 81 samples on a 130050 poly object in differnt positions and directions. Each test used the same sets of positions and directions. A 3 by 3 point grid evenly spaced on the object and ran rays from each point's x and z to each other in all combinations (even straight down) making a 3D web mesh pattern through the object. Shoting from 10 units over the highest point in the object to 10 units below the lowest point in the object.

Sparky's : 0.508 ms
NGC 4.02 Beta : 0.783 ms
MGC 2.03 : 22.271ms

NGC 4.02 beta was faster than Sparky's on some samples and Sparky's fatser than NGC 4.02 beta on others. If the sample were shifted a bit the times may have shifted the other way they were so close on some. Looking really good.

As Sparky said :

I just sent Lost in Thought a new version. So, we'll see if that changes anything. I'm seeing a significant decrease in load on the latest v4.02 beta (considering I just rewrote it again, lol)

0.562 ms for new 4.02 beta average with those settings and about 547 for Sparky's (my computer must be slowing down after running so many tests)

Sparkys test


NGC 4.02 beta test


You can copy them in 2 text windows to compare each test side by side as they were ran in the same order with all the same end and start points for each ray.

Keeps locking up when editing that last post so... Just found out the threshold was locked at 1000 with the latest 4.02 beta (was using 450 beore). When setting Sparky's to 1000 it averages 1.1ms per cast compared to NGC's 0.562. I'll have to wait a bit before setting them both back to 450. I use 450 as there are 450 polys per limb and the trees would be more even.

Okay, everyone who lost faith in NG raise your hands high so I can see you.

I'll tell you tomorrow. I'm taking the day off. Right now, I'm estimating no later than next week Friday (the 24th).

Ok guys this is verging on hijacking. Please move to another thread for discussing Nuclear Glory....even comparig these two plugins can be done there, just at the moment people with questions for sparky will get swamped with Nuclear Glory talk.
thanks

M.I.A is pending

Yeah, sorry about that I was about to post the same thing, it's my fault. The results posting has already been moved to the NGC forum under their benchmarking thread and a new thread will be created in the Program Announcements for NGC 4.02 when it is released which will contain the final results. The tests will be quite extensive not to favor either side. I will post the best, worse, and averages of each. So if anyone wants any info on this test will you please go to and post about it here: http://www.nuclearglory.com/php-bin/forums/view_topic.php?id=392&forum_id=2 Thank you.
