Doodle

[stevepoole]

Hi Again,

Sorry, I forgot to mention the essentials :

Numpad Keys are : left(4), right(6), up(8), down(2), also fore(x), aft(s), (e)scape. This is because my french laptop won't correctly map all keys.

When I get home I may try to do a standard QL version ! Good luck...

Steve.

Hi,
Spook_bas, the 'PacMan' in 3D space program, took more time to do than the other Doodles, as it was hard to work out how to get clear graphical output.

If anyone knows why a few recalcitrant pixels remain on screeen, please let me know.

The next Doodle, (16), only took an hour or so, as I have to fit in all normal holiday activities in each summer day too...

It demonstrates recursive output, but having little time free, I did it using iteration, which requires less cogitation to develop !

Hi,
Doodle 17 was an attempt to get extra colours by XORing them and redrawing the scene shifting one pixel right to get three-colour stipples.

To demonstrate the effet, the following images were repeatedly drawn. For brighter hues, change line 240 to be o=rnd(0).

The side-effect is the 'ghosting' outlines, which cannot be avoided, but in the context is unimportant !

Ladies may enjoy the outputs.... and get ideas from them.

Hello Folks,

Doodle 19 : Can you cross the 'Devil's Bridge' ? Yes/No. (There are three possible outcomes...)

Nb Dilwyn : This was supposed to be situated in Scotland, according to the Python Team !

Hi again,

Doodle 20 is a 'selfie' with a twist ! But I get flickering on my 3-core laptop, and wonder if this would be the case on mono-cores ?

My summer vacation is coming to an end, so today I will attempt a final doodle, before getting back to other more important tasks....

Nice. The filling of the beard flickers a bit. Seems different if FILL is used with panning or scrolling. I am not sure, if there are other MC extensions for a smoother and faster FILL.

[stevepoole]

Hi Ralph,

I wonder if the cause of the flickering comes from FILLing the 'off-screen' part of the 'body'-ellipse ?

While one core is processsing the unwanted filled lines, another core may be doing the CLS ?

Again, does the flickering occur on mono-core systems ? When I get back home, I will try on my SGC QL...

Or, is it, as you suggest, a problem with the FILL routine itself ?

Regards, Steve.
