Maybe I'm just being pedantic:) (but it is the morning and I can't deal with anything more complex)

but 360degrees is equal to 0 degrees so you'd want to go from 359 to 0 or 360 to 1.

All the Best, Ed.

Hello,

Perhaps I'm crazy here, but there are only 360 degrees in a circle. Shouldn't your line go from 360 to zero? Or do you somehow want 720degrees of rotation?

I would link a metro to a counter to a [mod 360] (the result would be 0 to 360 forever and ever and ever)

Regards, Dave

Hi folks

been fooling with GEM and loving it. Making cool .obj files in Wings3d etc..

But i would like to have a simple spinning object for demo purposes

How can i set a line to go from 360 to -360 etc.. i am sure this is a simple question but i am a simple kinda guy...

Please disregard my previous post about how to load obj files in gem!, I was a little bit tired this morning and my brain was not functioning the best!

And to correct myself in my earlier message,

[mod 360] actually produces numbers between 0 and 359 forever and ever and ever.

You're not being pedantic, you're being wrong, and I'm the real pedantic this morning ;-)

If you want to make a full circle but so that the circle function is a bijection from a real segment onto a circle, then you need a half-open interval of length exactly 2*PI radians, or 360 degrees.

So 0 to 360 degrees, with either of the bounds excluded, is a proper interval for that. If, for example, we pick the one that excludes the 360 bound, the set has theoretically no maximum, but in the float32 approximation, 359.99997 is the maximum, as it is 360*(1-2^-24).

Have a good day :-)

Hi folks

i am pretty limited on my linux A/v side save for cinelerra so i am focusing my GEM tests on WinXp and OSX. I think i have aquired the most up to date version for OSX but where do i locate the newest for windows? I was having incredible performance from GEM with my Sony digital 8 on OS X. and Fantastic luck with the tutorial examples.

I would like to see how this stacks up with the windows version.

cheers~

Hi Pat,

The latest build of the CVS version of GEM for Windows is available at www.bogusfront.org

You'll find the performance for patches with lots of texture transfers to be a little disappointing on Windows I suspect, as Microsoft has not optimized this path as much as Apple. Please post the results of your comparisons.

Cheers, Daniel

Direct Show works nice on Windows. But there really is little comparison GEM G4 is loading 2 7.3GB videos dumped out of Final Cut and randomizing,tweaking size etc..

wowee zowee this computer stuff is fun

Yes very disappointing compared to my G4 I am grabbing the CVS binjaries right now. I have gotten msdn Visual.NET for compiling on windows but all the folks at school look at th einterface and say "oh wow microsoft really screwed it up.

Is there a simple how to for compiling with this monster?

funny you should mention a chroma key because keying has been on my mind. Just started using zmatte for post work.. RTalpha subtraction and convolution as you mentioned will be a wonderful tool as well. what i would love to see is the ability for GEM to read different file types like .flt, .iv, .pfb etc.. and have be able to tweak those inside a gemwin...

and of course a way to dump out to .mov or .mpg or avi is a must at some point

Hi Pat

Good to see that you are having a nice experience with the OSX GEM stuff - Jamie and I have put a lot of work into making it run well. I have just finished adding some Alitvec versions of the chroma_keyer and convolution function and will be working on some more optimizations and also finally starting on the RGB side of things. Oh and if you are using pix_video right now try yuv_video and it should speed up about 2.5 times. We need to sort out the YUV and RGB defaults and switching soon.

What machine are you running GEM on? I would like to compile a better set of recommended setups for GEM on a Mac.

Also, what further tutorials would you like to see? I have a short list of 'advanced' ones that include color-space, texture coordinates and the particle system - it's just a question of sitting down and doing them.

I would like to see how this stacks up with the windows version.

Hi So we today successfully got spatialised audio running via socket with OpenAL and Performer. with a flypoints program dumping xyz coordinates to a text then hardcoding in the OPenGL map locations.

I would still like to be able to read these coordinates on the fly. I realise OSC seems to be the way to go but i am unsure how we would set up Perfly to spit out the properly formatted info for OSC/pd to read. I have talked to a few folks on the msp list and they say they are using OSC successfully but i am a network newbie when it comes to these things

anyone else in this area

bueller...

it's true, you get numbers between 0 and 359. but it's possible that you reach an overflow ... in these cases it's not continuous... well, overflows won't happen that often, but you should be aware of this ;-) that's why i'd prefer the couter that's reseted when reaching 360...

Overflow will never happen.

It will stop at 16777216.

For, do this:

[16777216( | [+ 1] | [& 255] | [print]

print: 0

This is because 16777215 is the last odd integer available in float32 format.

Note: if you save the patch and reload, the result will be much different:

print: 241

but that's because PD does a little too much rounding while saving the patch. but with binary<->decimal conversions, it's either too much or too little: the "number of significant (decimal) digits" is not integer.

And here's a patch that works with negative numbers at 1/100 precision.

if you need a modulo that works with floats, probably try [wrap] from zexy (quite new; use the cvs-version or get the latest from ftp://iem.at/pd/Externals/ZEXY ) it is also useful, if you not only want to wrap between [0, 360), but, say, between [-180, 180), or [3, 4) (maybe not that useful with degrees)

but then i am glad, people sent real pd-patches and not references to externals.
