Haaaaaaaa!

Very cool, Carl!

You've got the 1st element of the crash nailed!

Get the impact rings, cycle parts, and add the glow and you'll have recreated a VERY authentic looking light cycle crash!

I can't wait to see the finished crash!

So glad you're playing with your light cycle models again!

Thanks... I was working from this...


The red out line is the exact shape of my 'splash' for lack of a better word. There are 3 crashes in the film and I believe they all use this exact same shape. In all it's only shown for the first 7 frames after the crash and I've even measured it's size in each frame. Looking at the mesured relative sizes between frames I found this interesting.

The second frame splash is 1.3 times bigger then the first.
The third frame splash is 1.288558844 times bigger then the second.
The forth frame splash is 1.343335827 times bigger then the third.
The fifth frame splash is 1.354222791 times bigger then the forth
The sixth frame splash is 1.288421138 times bigger then the fifth.
The seventh frame splash is 1.27968016 times bigger then the sixth.

This average comes to 1.30903646.

So I'm using 1.3 to the power 0 to define the size of my first, 1.3 to the power 1 to define the size of my second, 1.3 to the power 2 to define the size of the third and so on...

Considering the error in my measurement and the fact that shape isn't shown from strait on I feel I have the relative sizes calculated exactly the way they did.

The impact rings are next.
The cycle parts will come after that.
Then I'll work on the wall height going to zero.

The glow is something I'm still thinking about. Only in the first crash did the wall glow before it shrunk. To be honest I don't think the glow effect was something they modeled at all. I think it was done in post processing by hand. It could have been as simple as taking a pen light to large prints as they were exposed.

I do and I don't. To me half the fun is getting there. It wasn't that long ago that I thought I'd never be automating this code to the degree that I am. To be honest I simply didn't know how then. This sure has been a fun road to follow and I've learned alot along the way. POVRay is quite a powerful tool to play with when you get down to it. That said I've now also just found my second bug in the POVRay language itself. I've never found myself programming around bugs that weren't my own before.

TheReelTodd Wrote:So glad you're playing with your light cycle models again!

Me too... its funny I took a long enough brake away from them that I'm now looking at parts of my code and having to relearn what I did. Don't worry... it's coming back very fast. In fact just today I was digging through a piece of code trying to figure out what I was doing and upon figuring it out I realized I'd solved the problem the hard way the first time and I cleaned it up a bit and removed about 10 lines of unnecessary code. It does me alot of good some times to take a brake and come back to these problems with a fresh start. I see solutions now that I didn't see earlier because I'd gotten too close to the problem. I hope that makes sense...

Carl

Ok... I'm back to being me again. Someone really needs to fix that little grid bug.

Take a look in his gallery. He has much more stuff in there. ^^

Well, my take on it is that you seem to learn a lot more each time you play in the world of TRON. I love the stuff you do and can't wait to see this one completed. You really shouldn't look at completion as the end - because there are so many more things you will be able to create after this exercise, and the one after that, etc.

As for me, I personally enjoy the creative process (in my own works), but I REALLY love to see the completed project all done. There's just nothing like the feeling of viewing the final work, and getting people's reactions to it.

Yeah - I'm pretty sure the glow was not rendered as part of the image, but more likely manually animated back-lit enhancement to the elements that do glow.

It really isn't all that hard to recreate, given the tools you have to work with.

Here's a simple way of doing it:

Render the sequence twice. Once is a regular rendering. The second render will only be the elements that end up glowing. With the "glowing" elements, run a PhotoShop batch process on the frames. Remove the blank background (make sure it is not a flat image, but a single layer with no background so when you remove the BG it is transparent), and apply a light color overlay to the glowing elements (make sure it's set to screen), and then add a soft outer glow (like white, or very light blue and also set on screen) to it. In the video editing application of your choice, overlay the glowing element frames over the regular frames and set the glowing elements matte setting as brighten or screen or additive whatever setting your editor allows to make things look like they're glowing, or adding light to the image. You may need to play with the opacity of the glowing element layer to get the look right.

Ok, that's really simplified, but it will work. That's how I accomplished any glowing element in my On the Cutting Room Floor of Oblivion video. Anything that glows, is actually another layer of just glow applied to the layer under it.

Well, I hope that helped a little.

Grrr - short on time right now, Carl. I'll write more tomorrow.

Given the crap that Lucas has given us over the past six years now, my question is... who gives a sh**?

How did Star Wars get in to this? (Unless Th1rt3en posted something on it in his journal....)

wwwmwww Wrote:Simple!? I don't have a clue how to do what you descriped above or if I even have the software capable of doing that. I think I understand it all so maybe that's a step in the right direction. I do have an idea for how I might be able to render the effect in POV-Ray itself but it's probably far slower then your method but not if I take into account trying to find the time to learn how to do what you describe. I do have Paint Shop Pro 7 but can it even batch process frames... I don't know. To be honest I don't know how to do 99% of the stuff I assume it can do. I can't even make nice animations at the moment due to the problems I've talked about before. For these short ones I'll just post GIFs but I need to get that problem solved eventually too.

Sorry about that. The things I described are generally simple, but may sound more intricate if you've never tried them before. I believe you understand the logic I explained, the rest is just implementing it in the software you have at your disposal. Trust me - the things you are already doing in POV-Ray are far more intricate than what I described. I think you probably have what is needed to pull it off... except maybe the video-editing app. You'll need a video editor that allows multiple layers of video and can composite the layers in the style of your choosing - in this case, you'd want to composite the layers in "screen" or "additive" mode. If your video editor does not allow for multiple video track compositing, you can always simply combine the layers in your photo editing app., and then animate the completed composite frames.

Of course, if you do have a way of generating the soft glow in POV-Ray, that's probably the best way to go. Then you need only render the frames and compile the animation. That would be the most simple, and efficient way of going about it - fewer things to worry about and fewer things that have to be stitched together in post.
