THE PLACE FOR ALL THINGS BRYCE - GOT A PROBLEM? YOU'VE COME TO THE RIGHT PLACE


Subject: Realistic motion blur? It may be easier than you think.

Weeeeeeeeeellll... sorry, but I thought the best image to do this with was a metaball one. I am using a metaball model I made a while ago. for this experiment I animated it for 10 frames ( I know woopdee doo ) I tried to get a realistic motion going so that I could see how well this blurring attempt worked... Anyway, onto the juicy stuff. I rendered the 10 frames to a bitmap sequence, then I deleted the floor and rendered the first 9 frames with an object mask. Now, onto photoshop: I used a batch processing macro I made a while back to quickly chop out the metaballs on the first 9 frames using the object mask as a reference. IE anything white on the mask gets deleted. But, you can do this with the magic wand tool if you wanted. I then aranged the images, frame 10 on the bottom layer, frame 9 on the second. And because each frame is offset a little, and the top ones have the background cut out, you can see how it progresses. (I'll do another one so you can see because I don't have this stage of the project anymore) I then set the transparency of the top 9 layers to 10% and applied a gaussian blur to them, And voila, instant...well not so instant and actually a little bit annoying to set up...motion blur

Here's the second example I made. You can see the motion blur better in this one (that it's not just like doing a radial blur in photoshop. The faster moving area in the center is much more blurred than the slower moving splash/outward moving ring.

Ornlu.... You are doing some amazing studies in Bryce lately. I really like seeing what you are doing with Bryce. I am very intrigued with your way with metaballs.... This is a very interesting way to implement motion blur. ~ Swade ~

oops, here's the second image. The main thing about the 9 layers that you blur (only blurred very slightly) is that all you can see is the object that is moving, everything else is either chopped out with the magic wand or the distance mask.

I think I get how you made the motion-blur, but how do you make those nice fluid systems?

Very clever - how many metaballs do you have there? I assume most of the splatter effect is using a procedural transparency.


Ornlu ( ) posted Mon, 21 July 2003 at 10:36 AM

RayRaz: patience =P lots of tiny metaballs that bring my computer to the brink of castrating itself. (because it can't stand the sight of meta"balls" anymore, get it, wink wink nudge nudge) It's really not that dificult. All I do is make a cylinder of metaballs. then randomize it some. for the splash I multireplicate them outward in a cone like direction then randomize. And the ring is just that. make a ring, do some control-D control-D control-D untill you get a ton of metaballs, then randomize. Obviously the randomization is not just... well... random.. You do it with a design or goal in mind. (and you don't randomize the whole thing. Modeling things like this is mainly about patience. and the willingness to have your computer hate you for the rest of its existance. Phantast: umm, that's 8,000 metaballs, not quite as many as my other images, but a faster render for sure. And no it's not a procedural transparency, it's all metaballs. All this scene is..is a single omni light, 8k metaballs and the default ground plane.

cool. Simplicity is powerfull.

I'm more and more amazed. It seems you come out with something cool each day, pal.

Since my metaball fluids always seem to cause a stir, I thought I'd De "box" one of my earlier metaball liquids. This was one of my first. My newer ones are WAY too complicated to de-box (I do the metaballs in sections and box each metaball then box each section) so the newer ones just look like cubes =P And when I tried to unbox even the 8k metaball one above, bryce stalled for 30 minutes then crashed. This one has 2268 metaballs, and unboxed it's really a burdon on my cpu. I wish I could show you my later designs, because this really isn't my best work. But it lets you see how it is basically set up.

I redid the pic 2 shots up. I mainly took more samples so the blur has a finer look to it. Enjoy.

that is really good...insane...but good.

Wow. I mean, really, wow. Not only do I wish I had the patience, I wish I had the time. It's great to see what you do with Bryce--I've learned so much from you in the past few weeks (not that I've tried DOING what you do, but I understand the concepts). Thanks for sharing--I for one truly appreciate it!

Why thank you Mloates. Compliments are always accepted =P. Here's the gallery image. I don't really think it was 100% ready, but I felt like putting it there, so I did.

You know, I just realized you're supplying to us the particle system that Bryce lacks :) S.


Slakker ( ) posted Mon, 21 July 2003 at 3:22 PM

Man...no offense, but it looks projectile vomit. "Dang, clyde, i thought i told you to stop eatin' that there chalk!" Just kidding, looks like a good effect...except my P3 800 wouldn't be happy with me.


isulaelu ( ) posted Mon, 21 July 2003 at 3:41 PM

great tuto... i make my flow metaball now. thanks for let us see how do you make this awesome technique!


shadowdragonlord ( ) posted Mon, 21 July 2003 at 7:27 PM

Wow, Ornlu! I love your meta-creations...! (hah hah!) Meatballs are totally cool, but I hope they put an "energy" setting in the "next" version... (smirks) But particle system? Hmm, I think it's a cool effect DoubleCrash, but a system would have parameters and some way to control such silliness... Physics, something I'd love to see in Bryce. RayDream even had physics! But that was a "Studio" program... Still, I've played with the randomizer a bit, it's pretty cool! Never really thought about coupling it with meatballs and multi-replication...! Good job Ornlu.


Ornlu ( ) posted Mon, 21 July 2003 at 7:42 PM

I've seen fluid models made using programs like thinking particles, in cinema 4d, maya, etc. And frankly I don't think they look as good as what you can do manually with metaballs.


Phantast ( ) posted Tue, 22 July 2003 at 5:20 AM

Incroyable. I'm impressed.

You could make a nice DTE texture for the challenge for that. Great idea for people who have an inspiration block.
