Bored programmer series

[kazymjir]

Hello!

I would to present you new series of "Bored programmer", where I will show my new interesting effects in 2D/3D, games and maybe something more.
Please comment my work, feedback will be very helpful for me

This thread will be update from time to time, when I create something new.

Bored programmer - part one (balls)
UPDATED LINK
YouTube link: http://www.youtube.com/watch?v=VnhRtcIoiX0
Please view in HD! Quality is important!

Everything is rendered in real-time of course, using Irrlicht.
It's very simple algorithm, which checking in main loop positions of balls and colors with destination positions, and correcting them in single steps.
Little example:

Code: Select all

if ( ball.x > dest.x )
   ball.x--;
(...)
ball->setPosition(vector3df(ball.x,ball.y,ball.z));

Same is for color changing.
Everything is about 320 lines of code.
Very simple and simultaneously looking nice.

That's amazing! Any chance you'll share the source?

[LosNir]

That's awesome!
If I'm right, you load a JPG file, split it into pixels, and each pixel is represents a ball?

[shadowslair]

Haha! So simple, but so nice! I like the "Bored programmer" name choice either.

That's amazing! Any chance you'll share the source?

You simply take an image of say 320x240 pixels, take a color sample for each pixel, create a sphere with material color the sample value took, position it at the same pixel Y position and perform the "very-very-simple-x-axis animation" aek already mentioned until it takes its correct position in the stack and you are done! You can use higher resolution image if you wish. If you put yourself a limit of say 10000 spheres and the image resolution would create more spheres, you do some check and take your sample from the average color of 10x10 pixels. You can put many kinds of optimizations like batch-per-material color rendering, use billboard nodes and on... You can do this very easily and you`ll be proud of yourself. Asking for source code for each project announcement may frigten some devs to work in the shadows forever... Just kiddin`...

[Virion]

nice!! can we include this into irrlicht examples lol.
anyway did you optimize anything? how was the performance?

[greenya]

Very nice looking!

[Mel]

Very interesting video! Looks cool!

[Kalango]

Pretty cool indeed, would be nice that these examples would come with irliht sdk....just fo fun...

i'm agree with this, if the author allow this. it can be an irrlicht performance test too.

I'm fully aware how you'd do it, but I was just curious to see his implementation and how/if he optimized it. I'd even go as far as doing some LOD - given that they're just spheres, it wouldn't be difficult at all.

Also, it looks like the balls are moving along two axes - unless I'm mistaken, they don't all take a straight path to their final destination. Is this true?

[hybrid]

Yes, I'd also vote this one for the next Irrlicht example.

[B@z]

it looks great!

but i dont agree putting it into the examples. it looks good, but not something what beginners want to learn. IMPO

[Kalango]

Not as a tutorial, but as a separate downloadable examples or as a performance test.

[Midnight]

you'd be surprised what you can do with code very simply if you use your imagination. likewise you'd be surprised what an individual can learn from something you'd otherwise want to keep a secret in all it's otherwise magical uselessness.

Interesting use of a single example to spread atheist/science propaganda, I love it!

edit, oh and WOW how could I miss the wonderful title of balls!

[Lonesome Ducky]

I wouldn't say he's "spreading atheist/science propaganda," his channel videos could just as likely be unrelated. I don't believe he ever gave a link to those videos or ever told you to view the channel either. Just my 2 cents BTW, here's another vote for an irrlicht example.

EDIT: Woops, I completely skipped a few parts of your post midnight, ignore me altogether
