Please watch in HD. Title: Re: Mandelbulb flight Post by: twinbee on December 31, 2009, 05:46:44 PM Great fly-through over lush broccoli vegetation. All we need now is some music by Salomonsen ;)
Like to see some spline-like camera paths with this. Title: Re: Mandelbulb flight Post by: Snakehand on January 02, 2010, 07:35:18 PM I made another rendering using my dual GPU setup:
http://www.youtube.com/watch?v=qLX01LYS-24 I have tried to have some emphasis on zoom and close up action. Splines as suggested by twinbee are still on the todo list. Title: Re: Mandelbulb flight Post by: BradC on January 02, 2010, 10:05:41 PM Wow, that's an awesome flight. Implement splines! I used Catmull-Rom splines in this one and it wasn't as hard as I expected
http://www.youtube.com/v/osFmse_KycA&hl=en_US&fs=1& and your renderer looks better than mine. The quantities I interpolated were camera position (x, y, z) and lookat point (x, y, z). I used a key frame every 3 seconds or so. For camera roll, I kept the camera up vector as close to (0,0,1) as possible while still facing the lookat point. In other words, I tried to avoid roll because it was simpler, but roll looks good too.

Splines as suggested by twinbee are still on the todo list. Very nice indeed. Are you restricted by limitation to floats or can your GPUs/GPU code use doubles ? If possible I'd love to see a much deeper zoom - and obviously a much longer video - say a DVD's worth of flying round the Mandelbulb :D - well say a full 10minute HD video on YouTube anyway. Title: Re: Mandelbulb flight Post by: Snakehand on January 02, 2010, 11:33:00 PM Very nice indeed. Are you restricted by limitation to floats or can your GPUs/GPU code use doubles ? If possible I'd love to see a much deeper zoom - and obviously a much longer video - say a DVD's worth of flying round the Mandelbulb :D - well say a full 10minute HD video on YouTube anyway. Thanks. Newer GPUs have double support. On ATI each thread runs on a group of 5 float cores x,y,z,w,t - each core can perform a float opearation every cycle. ( 2 in the case of multiply and add ) - and transcendental instructions are limited to the t core. When calculating doubles, the x+y and z+w core can be linked up (leaving t unused). The 5850 then gets in the neighbourhood of 500 Gflops. But there are som practicalities, double vectors are limited in size to 2 elements (Brook+) so the vectorized code has to be restructured quite a bit. And binary search for DE etc. will have to do more iterations. I should perhaps try to use Newton-Raphson method first.

I'm hoping to acquire high-end video card/s sometime this year ;) Title: Re: Mandelbulb flight Post by: bib on January 03, 2010, 12:43:11 PM Wow! Excellent trip!
Title: Re: Mandelbulb flight Post by: jwm-art on January 04, 2010, 06:01:08 PM Love it!
Would though like to see further excursions inside some of the structures and a less angular flight path. Ok I see splines have been mentioned, but what about some dives, or a smoothed fractal flight path!? Title: Re: Mandelbulb flight Post by: Buddhi on January 06, 2010, 09:18:52 PM Snakehand, your animations are fantastic and rendering speed is incredible!
I don't want to be worse :tease2: and I also decided to render some long flight animation. After many (very many :'( ) hours of rendering I can present my work (1 frame / 10s) http://www.youtube.com/watch?v=xO5fXGqeM5c Title: Re: Mandelbulb flight Post by: twinbee on January 06, 2010, 10:07:38 PM We keep leap frogging each other don't we?
Buddhi, this is utterly remarkable. I've only seen a 1/4 of the video, because Youtube is *very* slow at the moment, but the amount I've seen so far is incredible. The resolution is great, but the colours, and special light glow are also amazing. You may have been exhausted over this, but how worth it has it been?! WOW^WOW^WOW. I'm also a teensy-weensy bit jealous now, so don't worry, I *will* attempt to re-leapfrog this (as I'm sure others will) :) , though you've given us a tough job - very cruel! ;) Title: Re: Mandelbulb flight Post by: cKleinhuis on January 06, 2010, 10:12:18 PM @buddi @bradc @snakehand
amazing videos ! and the last one i love because it is extremely long, has a cool lighting effect, and an interesting camera path ... well done! O0 Title: Re: Mandelbulb flight Post by: cbuchner1 on January 07, 2010, 12:07:29 AM I don't want to be worse :tease2: and I also decided to render some long flight animation.

Title: Re: Mandelbulb flight Post by: David Makin on January 07, 2010, 12:15:26 AM Most excellent - especially the end section :)

:alien: :alien: :alien: :o :o :o Title: Re: Mandelbulb flight Post by: kram1032 on January 07, 2010, 10:38:43 PM twinbee: You HAVE to watch the whole vid :D
It's amazing! I liked in the end that you didn't directly zoom into the "surface" of the brocoli-part but rather you zoomed deeper into the regions below the first brocoli. Under it there lies even more brocoli but it looked like the whole thing ended in a sperhical thing where all the brocoli-arms emerge from - maybe a true minibulb? if that's the case, you could zoom into the spine-region of that minibrot (the older pic named spine - I think it's from what equals a seahorse valley of a standard 8 degree Mset...) and from there look if the new details look any different :) However the whole video was really nice to watch. Great :D Title: Re: Mandelbulb flight Post by: mrrgu on January 08, 2010, 02:36:01 PM Wow..think that is the best flight path i've seen ;D
Title: Re: Mandelbulb flight Post by: twinbee on January 08, 2010, 02:57:40 PM Saw the rest - and awesome indeed.
Maybe I would've liked a little more speed sometimes in the middle to end section, but I'm nitpicking really :D Title: Re: Mandelbulb flight Post by: KRAFTWERK on January 08, 2010, 03:30:34 PM http://www.youtube.com/watch?v=xO5fXGqeM5c A mazing film indeed Buddhi, Thank you!!! On my whishlist is a deeeep zoom into "flowers" of "flowers" (not the broccoli) on one of the minibulbs, to see how long it continues to repeat itself, i made some images and will try to explain, I ran out of decimals in Subblues pixelbenderscript though... J Title: Re: Mandelbulb flight Post by: mrrgu on January 08, 2010, 03:44:11 PM Buddhi that is the best i've seen so far.. amazing!!!
Is this GPU or CPU ? Title: Re: Mandelbulb flight Post by: Buddhi on January 08, 2010, 06:37:57 PM Thanks for very nice comments.
Is this GPU or CPU ? It was rendered using only CPU. Unfortunately I still don't know how to write programs for GPU.Maybe I would've liked a little more speed sometimes in the middle to end section, but I'm nitpicking really :D About speed I have to improve it a little. In fact sometimes movement is too slow. On this animation speed was controlled automatically by distance estimation.Title: Re: Mandelbulb flight Post by: Buddhi on January 08, 2010, 11:10:38 PM I liked in the end that you didn't directly zoom into the "surface" of the brocoli-part but rather you zoomed deeper into the regions below the first brocoli. Under it there lies even more brocoli but it looked like the whole thing ended in a sperhical thing where all the brocoli-arms emerge from - maybe a true minibulb? I rendered static picture of Minibulb area in high resolution (last frame of animation).

I like a lot the shape of the bulbtree's branches :) Title: Re: Mandelbulb flight Post by: David Makin on January 09, 2010, 12:33:20 AM Super image !
Title: Re: Mandelbulb flight Post by: twinbee on January 11, 2010, 02:54:05 PM Any chance of rendering the ones (with the original colour scheme) at 16s and 1:17s? Those are my faves.
Title: Re: Mandelbulb flight Post by: kram1032 on January 11, 2010, 09:51:49 PM a great still :D
