Author Topic: My Best Analog Chiming Clock (Read 7391 times)

SierraKen · « **Reply #15 on:** November 18, 2020, 08:12:14 pm »

Here is a MUCH better clock. I completely remade the clock hands and added a new graphical seconds clock hand as well. It took me a few minutes to make a smoothly animated seconds hand but it's incredibly easier than it seems. All you need to do to find the degrees for RotoZoom of the seconds hand is this: angle = 6 * TIMER. TIMER is how many milliseconds since midnight. I also softened the hand graphics to add dark shade around them to look more authentic. I used B+'s idea to make circles around the hours, minutes, and seconds. Tell me what you think everyone. I also changed the colors around, I like these better. I'll update the original zip file and picture above and remove the last one. Here it is also below. By the way, it feels really good to be able to draw these clock hands when I've never been an artist hardly before.

Nice @SierraKen

The hands are picking up a nice style to them and I really like the blue hour dots more in the middle!

Thanks B+, I really like it too. I'll be using this often. :)

Hi @SierraKen

It's all drawing from bas code (the minutes hand is moving as if a seconds hand)

BTW @_vince this fixes line at 3 0'clock:

Code: QB64: [Select]

'PSET (sw / 2, sh / 2), _RGB(100, 100, 100)
FOR a = 0 TO 2 * pi STEP 0.01
    x = 100 * COS(a) + 100 * COS(14 * a)
    y = 100 * SIN(a) + 100 * SIN(14 * a)
    IF a = 0 THEN PSET (sw / 2 + x, sh / 2 + y) ELSE LINE -(sw / 2 + x, sh / 2 + y), _RGB(35, 35, 35) '<<< pset here
NEXT

LOL I can't believe I did that. I only copy/pasted the code that I saw, I didn't scroll down on the rest of his code. lol

Vince this is awesome! Very nice design. It just needs to be added the real time to it. I looked briefly at the code and can't really figure it out yet, but I'll look a bit more.

I also found out Ken modified a perfectly fine rotozoom feeling need to change parameter name ;)

Nice, I was definitely inspired by Ken's clock hands and wanted to see how hard it would be to render those vintage style 'calligraphy' hands in a short tight curve parametrization. It turns out it is beyond me. I had my sights on something like this:
(https://image.shutterstock.com/image-vector/vintage-clock-dial-set-hands-600w-496516774.jpg)

I have no idea how you'd parametrize those spade like curves with all the loops and cusps. I am aware that there's an algorithm that can fit a sum of sinusoids expression to any arbitrary curve but it would not be as tight and elegant as the stuff here: https://mathworld.wolfram.com/HeartCurve.html - that math is beyond me. I'd be impressed if anyone can pull off a fancy spade clock hand curve with a similar expression. My hands are a sloppy few minutes of trial and error.

I am also aware that the program is a bit rough with mistakes and misalignment but had I polished all of that it would no longer be the cute 70-liner -- I would then be better off hand coding each roman numeral and so on. I would be down to code up the ultimate QB vintage clock some time, all the flourishings, calligraphy, fancy spirographs, true 3D shadows on hands, etc and no external images!

SierraKen · « **Reply #25 on:** November 19, 2020, 09:16:17 pm »

Thanks Vince. RotoZoom takes care of most of the math by just rotating the picture. I tried to add the real time to your clock this afternoon but no luck. Your math is beyond me there is why.

Don't worry about it Ken, I was proud to see you using a SUB! BTW hdl means rotozoom was looking for any image handle to scale and rotate.
