Mondrian, next try to get a TOPIC ...

Now, last post got lost in translation ...

This video inspired me to build this for CPC (6* ..) in MODE 0

[AMSDOS]

I could probably recreate this in Hisoft Pascal if this is an invitation to code in ones favourite language, I even wrote a Fill routine earlier (based on what I wrote in BASIC), though faster for being compiled, squares are straight-forward.

Well, it is just a quickhack from me to show CPC could do that fast and nice in Loco.

Of course everyone can try to write it in his favourite language (JAVA with javagrinder ) for CPC and we would have the most variant oldtimer art computer

Indeed, definitely another one to put next to the QuickBASIC example on Rosetta Code!

One query, unfortunately while I was trying to work out the if number of filled areas were important, I looked up some of that art and noticed the problem it presents of drawning the Black Lines as a series of Squares and Rectangles, which means Lines don't completely run up and/or across the screen  Some of the examples I saw had shapes running at different spots, forming differnt size squares or rectangles. I tried coding this, which kinda works, though I was trying to remove the L shape (which Mondrian doesn't do), by adding Lines 1041 & 1042, though it's not quite working. The idea with this is to draw a line from the shape and look for an intersecting line, unfortunately I can only post as a Screenshot.


Update: I made some improvements on what I coded last night, it's still not 100% perfect, though seems to be behavouring itself on the most part with the occasional L shape creeping in. I'd also had some additional variables, which didn't seem to be doing anything, I think I was trying to use them as a counter and if a certain number was reached, lower the ypos down the screen, though didn't make much difference without.
