Mechwarrior physics...

Idea for orbiter addon

Another idea for an addon

Houston, we have a problem...

Mechwarrior physics...

:rofl: I laughed out loud so hard at this I got strange looks here in the office.

Hahahaha, I'm enjoying this 'unixkcd'. (xkcd.com on april fools)
Apparently I'm a kitty, a cheater, and get free shipping... I'm trying out more commands. XD

I'm in awe at my own raytracer.
I added a plane. (And chose red/black checkerboard for color)
It totally changes the look of the image. The spheres aren't in an entirely empty black world. And because the spheres are so specular, there are TONS of reflections and shadows visible.
An observation: Antialiasing and fairly uniform shading of the 'checkerboard' makes the blocks of the plane seem strangely 'fake', as if it was drawn in Flash or something.
Another: OOOOH!!! Check out the reflection in the red sphere, of the yellow one floating. Something about that just looks cool!
I'm really liking how my raytracer is turning out.

I think the fake look of the checkerboard is largely due to the fact that we never saw such a giant plane with this pattern. Then again, I've never seen so many floating orbs either

Looking good!

I have no idea what a "ray tracer" is. Looks like a bunch of graphics to me...I also had no clue what the "mandelbrot" thread was all about...

Hehe. Assuming you aren't kidding: A ray tracer draws 3D graphics basically as realistically as possible. It's basically the opposite of tracking a photon on its way to a camera. Reflections, refraction, exact mathematics of the shape, etc. should be taken into account. The Mandelbrot set is the result of a recursive complex (complex plane) equation. The plain Mandelbrot set has points that are either part of it or not. So a real Mandelbrot set would be colored simply black and white for example. The psychodelic colors are based on how 'far' a point is from the Mandelbrot set usually. I 'made' (not much was original, it was mostly copied from pseudocode on wikipedia) a Mandelbrot drawer in Java too. But I never got it to color smoothly.

I'm basically done with the Mandelbrot for now. I've been working a lot on the ray-tracer. It's taken a lot of time and effort, but I've gone from a big blue circle to several reflective spheres over a plane about 99% on my own. Every little aspect has been a bigger programming challenge than I first suspect.

A blog record with pictures of a Foxtrot class submarine turned into a naval museum

After watching the BSG miniseries, I can't help thinking that turning a warship into a museum sounds like bad mojo.

Well, when they fire up the boilers on the New Jersey, let me know. I want to see some big gunnage.

Uh, okay, man, my head doesn't feel so well....

For any abandoned military and industrial hardware lovers here, a blog post with pictures of an abandoned Russian ABM A-35 rockets launch site not far from Moscow. Don't forget to watch the scary video!

Perfect! You just need to team up your ray tracing and Mandelbrot work for some 3D Mandelbulb action :thumbup:

Yes!!! I've seen that, and totally wanted to make one. But... it could be a while til then. lol
(And btw 'done with the Mandelbrot' means I'm just not working on it. It's hardly finished. lol)

Doing everything and anything Battlestar Galactica. I want my BSG!!!



note:
(though in reality bsg means BattleStar Group, not Galactica) Most sci-fi'ers call the show bsg..

Damn, was experimenting with making raytracers.

Rather simple one (spheres, plane, semi-unlimited reflections) on an 8-core CPU runs at 0.8 seconds per frame, and 4 seconds per frame on one core.
The same thing rewritten in GLSL to run on GPU gives 800 frames per damn second.

I knew, in theory, that graphic cards are way faster than CPU's, but that's the first time i got it in perspective just how much faster...

Now you know why I can't wait to start programming on the PowerXCell/8i processor card of the institute. :thumbup:

O_O I need to try this. :lol:
(I also need to get a decent GPU)

Quick_Nick "passed the Turing test", just noticed that, nice! Only on OF do you see so many geeky references! :thumbup:
