I called this rain drops drawing algorithm becouse it is suppost to simulate rain drops falling into the water, but it also makes a nice chrome effect.
(I`m studying making fractals and using/creating algorithms for a texture generation utillity)



This WILL run in DBC as well, but i do not really suggest it, becouse it`ll take a while untill you see the actuall result.

I'll bet you can speed that up alot by using memblocks.

I made a nice change to it:

Cool I wonder why that code takes 2.7 secs on my fast machine at home and .5 secs on this slow work machine

Different patches maybe?

Same patches. Probably due to my hyperthreading processor limiting DBP to 50% usage at home I guess.

Oddly enough still the memblock version of that code runs the same speed as the dot version on this machine as well. The memblock is way faster on my machine.

Back on track though, Dodic you better pull a rabit out of a hat or something. Benjamin is winning LOL.

Winning what ? LOL, but yes, if anyone actually thinks that this algorithm...at least looks...nice, then i guess i`ll come up with a few more algoriths, sence it is for my texgen app, i`ll go for some "earthy" algorithm, and well, other algorithms i need for my app, though there will be many...algorithms before i get it right (the terrain one), so when i get something funny, or at least something that i think looks nice, i`ll post it.

p.s. nice "move" there, lol

edit :

It takes about 0.5-1 sec with the dot sistem on my machine...

p.s. A n00b question, Benjamin, when you added "lock pixels - unlock pixels" what does it actually do ? i mean it calculates it somewhere and then shows it i guess, but do you get faster calculation with it ?

Yes it make 2d drawing much faster. Check out the help files and example and you can write some pretty fast 2d stuff.

Quote: "LOCK PIXELS

This command will lock the current bitmap for faster reading and writing of visual data. Rather than use DOT and POINT to manipulate pixel data, use this command in combination with GET PIXELS POINTER to write directly to the memory storing the visual data."
