Happy Sysadmin Day

Ah. I was thinking more of:

Not enough CSS transition.

I don't know enough Blender to animate HSV instead of RGB.
Hue rotation through RGB is easy: just go through all the values between the minimal and maximal RGB coordinate.
Have a look at what happens to the RGB fields in [photoshop|whatever] when you drag the hue slider.
-
That only works if you have fully saturated colors, but that shouldn't be a problem in this case.

Maybe, but it's easier to just use HSV. It gives me a better notion of how fast I'm rotating around the hues without having to think it through. In particular, I can be reassured that I'm not moving back on the wheelThis new GIF feels (to me at least) much smoother, although it still needs work. But maybe it's just me:

Bah, stupid thing still interpolates over RGB even though I've given it colors on HSV:
Also time interpolation is wrong, but that's my fault.

Changed renderer:
And that's enough balls for today, I think.

You'd have about $1.20 in change.

Well, there's that but I was assuming the unspecified qualifier of 'if I had a nickel for every time this has been said'... in which case he'd have more than $0.05 but somewhat less than the unstated hyperbole value implied.

...in which case he'd have more than $0.05 but somewhat less than the unstated hyperbole value implied.
Heteronormativity strikes again.
-
I'm sorry, was I supposed to go through and explicitly state 'he, she, they' because for the sake of brevity I chose to omit the extra qualifiers?
-
What? No. Just underestimating the interaction with balls.
I used to be a catcher. Make of that what you will.

No, no, we concluded that 'it' was offensive in the misandry thread, didn't we?
-
"We" may have concluded that, but I didn't. And I'm not really sure what "we" concluded, because I skipped large parts of that
threadtopic.Filed under: If it is offensive, all the more reason to use it, especially when referring to @Nagesh.
-
This guy is offended that some find his name offensive!
-
That only works if you have fully saturated colors, but that shouldn't be a problem in this case.
It works all the time. Use the current max and min RGB value.

'it'
The correct form is “s/he/it”. We don't want to unduly exclude anyone meriting that term, do we?
-
-
If I had another nickel for every time that I had a nickel for recursion...
-
You might have to supply the colour mapping function yourself. “Fortunately”, Wikipedia has far more information on this than you might possibly want.
-
alter the hue while maintaining constant Luma;
That's gonna be tricky. Not even all graphics programs agree on which luma to assign to the different hues when greyscaling*.
) greyscaling is not the same process as desaturating*. Greyscaling takes into account that RGBCMY all have different perceived brightnesses. Compare 100% yellow and 100% blue, for example.
**) I don't know if I'm splaining things to people who already know this shit, but it's an inb4, I guess.

Grainy Cycles is grainy. Needs more passes.
Not just that. The conversion to (256 colors) GIF was unforgiving. The frames are badly dithered.It was either that or the mother of all color bandings (still with grain).
-
The bonus thing is that having a grainy render will reduce banding, like a pre-compression dither.
-
The frames are badly dithered.
Upload the original somewhere, and I'll convert it to a much nicer-looking GIF.
-
Here's 2000 passes (up from 200), still using the Gimp to make the GIF (Open as Layers, Export to, .gif, as animation)
Straight export:
With Optimize for GIF (in this particular case it looks worse and makes the file larger):
After converting to 256 colors with normal dithering, no optimization:
"Reduced color bleeding" dithering:
Positioned dithering:
An unconverted puke green frame:
Blue balls, they almost look like they're glowing:
Have some red ones too:
@ender Zip of PNG frames (frameskip is at 5, hence the numbering): https://www.dropbox.com/s/q1mehumesj128f6/ballsy.zip
Will gladly upload .blend if anyone wants it too.

You're really not ruining Sysadmin Day.

@PJH If you want to grab my balls then go right ahead.
I'll move the camera to make them match your avatar more. If you're not interested then that's cool too.@dkf Thanks for the link. I'll read it when I have the time.
See you guys later.

True, but you don't have to be exact. If you're really doing it right, you have to get into screwing around with the CIE colorspaces, and they're… non-trivial and require knowledge of the target display device and the viewers' lighting environment too. Luma's a reasonable approximation.
-
Well, it looks like I should ditch Gimp and just use ImageMagick's convert:
-
Is that light color you're changing or animating the texture btw?
-
Looks like it's texture animation. The surface underneath isn't a perfect mirror, so light changes would show up.
-
I'm changing diffuse color of the ball's material.
-

Real world logic, yes. 3D renderer logic, not necessarily.
IIRC, you can set a material to accept only some lights and ignore others. CBA to install/start Blender to check though.

Which makes
you@dkf (because Discourse will not decide this is a reply to no-one in particular) right, but it is possible to do it with lights as well.And I'd change the diffuse myself, but I suck at it so I wondered if it's a good idea at all.

Well, it looks like I should ditch Gimp and just use ImageMagick's convert:
I'm pretty sure that GIMP doesn't handle local palettes. Also, GIMP 1.2 has much better colour reduction algorithm than 2.x.Here's what I came up with:
- With dithering:
- Without dithering:
-
Wow, your balls look way much better than mine.
How did you make them? GIMP 1.2 or something else entirely?
-
How did you make them?
GIF Construction Set Professional. It'd take too much work with GIMP (since I'd have to manually convert every image to indexed).

You're having far too much fun with balls.
-
Magic!

Hmm you could make a coloring book for adults out if it ... the Big Balls coloring book or something
-
IIRC, you can set a material to accept only some lights and ignore others. CBA to install/start Blender to check though.
Yes. I've never used it, and I can't remember whether it's under material or texture options (and CBA to open blender to check), but it's definitely there somewhere.
-
I CBA either, but I think objects are put in layers and you can tell lights to only affect certain layers.
At least I think that's the situation with the "internal" renderer. The new Cycles renderer is graph-based, I'm sure it's even more flexible than that.
