Quite a neat effect, I removed the syncrate of 50, just for fun

I ran it on DBC, froze up my pc and had to reboot, losing ~50 lines of code from my other program I know I should have saved, learned my lesson there.... I'm very unhappy with you....

This program only calculatetes a kind of sinus function
and writes results to sit() array. Then the program calculates
dot colors in memblock, converts memblock to image and
textures cube by this image. I tested both versions on
DB 1.13 and DBPro (don't remember version).

I found one problem in DB 1.13: TEXTURE OBJECT command
did not worked here as expected. That's why I delete
cube in main loop and then I create cube again.
But I don't think that I can crash computer by this simple
program anyway.

holy sit!
sit(sit((sit(2*i)+sit(3*j)+sit(k)) and 255))
i can't possibly wrap my head around that.

SIT is a precalculated sinus table of 256 elements.
sit(i)=int(127.0*(1.0+sin(i*360.0/256.0)))

The idea of this table is that argument lies in area 0-255
and result sit(arg) also lies in 0-255
This way we can create numerous fun working functions.
And in any case we stay in area 0-255, and then we use
a result as red, green and blue components of color.

sit is using here only as variable name and has nothing common
with illiterate words of any human language

I had a play around, and now i have a much better understanding of memblocks. in the image memblock, i take it that every fourth byte represents the alpha value of teh pixel. mabey i'm wrong though. The math was way beyond me!!! but it is one of the best sub 20 line programs i have ever seen. very well done m8.

regards, geecee3.

PS. this would be even better if applied to a pre made texture, only effecting the black areas or any other key colour. these mem block thingies really rock!!

Hmmm. I get an error.
5105 - memblock position out of range.

At this line:
write memblock byte 1,p,r:p=p+1:write memblock byte 1,p,g:p=p+1:write memblock byte 1,p,b:p=p+2

Maybe I'll restart and retry.

Your probably trying to write to an area that doesn't exist.
