sphere resolution hack?
« on: Oct 24^th, 2003, 4:22pm »

i am wondering if there is a way to change the resolution of a sphere...?

something like sphereResolution(10); would be nice, or alternatively sphere(radius, resolution);. which would allow each sphere to be drawn with it's own resolution.

...has anyone discovered a built-in command for this, or does anyone have an idea as to how you can hack it?

nope, can't hack it at the moment as it's still hardcoded via a "static final" value (30). i think a flexible resolution has been proposed before though and AFAIK it should be in the pipe...

maybe you should have posted this under "suggestions"! wink...

allright.. the reason for my question about "changing the resolution of a sphere" is because of the problems i have encountered with the following:

i want to make 3D worms... i was playing with movement using curvePoints, and ended up making a sphere make a work-like trail in 3D space (funny how the sphere can HIDE behind a trail ... i guess this is a feature (maybe even bug?) of Bagel?).. anyway, here's a link:
http://proce55ing.beyondthree.com/testing/animated_worm_trails/index.htm l

So... I thought i would be nice if the length of the worm would be limited, to say 20 spheres... however, this ended up being a heavy processor task, which forced me to go to low resolution and REALLY poor framerate:
http://proce55ing.beyondthree.com/testing/animated_worm_memory/index.htm l

...i exported the last example as a movie:
http://proce55ing.beyondthree.com/testing/animated_worm_memory/yellow_wo rm.mov (1.5 mb.)

anyway .... to achieve a mixture of the two - a high-resolution worm where the length of it is of limited dimension (and not infinite as the first example) I really need to be able to control the resolution of the spheres

...anyone?

ahh shit toxi ... double posting again!...

you're right - this has turned out to be a SUGGESTION! (hello... operator.. feel free to move this!)

hey mikkel, i hope you'll pleased to see this

http://www.toxi.co.uk/p5/xsphere/

it's not a hack as such, but a rewrite of my old lingo code i used for macronaut. it's not properly optimized yet (not using TRIANGLE_STRIPs) but once this is done, i'll try to get ben to integrate this instead of the current sphere() function...

btw. move left-right to change res, click to toggle filled/stroked only

I went playing with Toxi's xsphere code and I ended up doing a little applet I put on my site: http://koeniedesign.com/?p=about

I mapped an image of a worldmap on the sphere, but you can put any image you like around it. Source is here: http://koeniedesign.com/globe.pde

(fwiw, this code was added by toxi to the main graphics engine around rev 6
