[Fwd: obj importer uvw coordinate problem]

---------------------------- Original Message ---------------------------- Subject: obj importer uvw coordinate problem From: "sebastian pirch" <sonsofsol(a)gmx.net> Date: Tue, December 23, 2008 2:37 pm To: brandt(a)subnet.at -------------------------------------------------------------------------- dear MR IOhannes Zmöllnig ! {normally, at this time of the year someone writes a wishlist to the christkind, in my case im afraid, its only you who can help my out ; ) ...} my name is sebastian pirch and im playing with pd and gem for some time, and in the first place i want to thank you for the great software you guys developed. i come from the 3d (s max) corner and im trying to make some interactive installations with gem, so its obvious to use the .obj importer in gem. and right here is my problem: i couldnt manage to get the texture coordinates imported from max. It seems to me as if the obj importer just merryly ignores existing UVW coordinates and applies a generic planar mapping to the model. I tried everyting in my possibiliteis to find a workaround, tried different OBJ exporters, and in the end wrote a max script which exports all the U + V coordinates of every texture vertical to a .txt file, trying to re - apply the given mapping with gem's [pix_coordinate] object. But without any useable result. So my suspicion is that gem's OBJ importer assigns new vertical numbers to the geometry, and i have no idea how to fix that problem in that case. I think, this issue is kind of a missing link in a otherwise great OpenGL environment gem provides, and with correct coordinates lots of mind-blowing things would be possible. in fact, this would give gem nearly all key functionalitys of a game engine. Also i saw, there are a bunch of tools readmade wich are only waiting for this feature to be implemented, for example the [pix_displace] object. So i hope you find some time to help me with this issue. Maybee it would be enough to get the right verticle numbers assigned while import of the obj file, as then, it should be easy to re - assign the mapping, and open up other possibilities like apply skinning for characters as well. I know, you must have lots of interesting and importend stuff to do, so i dont expect you to jump up and send me a working exporter the next day. I ' m hoping you possibly know a solution for the problem, and i will certainly do all in my possibilitys to support you in finding a way to solve this. merry christmess lg sebastian pirch -- www.3rd-eye.at Sensationsangebot verlängert: GMX FreeDSL - Telefonanschluss + DSL für nur 16,37 Euro/mtl.!* http://dsl.gmx.de/?ac=OM.AD.PD003K1308T4569a

unpack~ clone (sort of)
by Jamie Bullock 23 Dec '08

23 Dec '08

Hi, I find pack~/unpack~ very useful, and I wanted to see if there was a pure pd approach. Attached is a first stab at an unpack~. It gives identical results to zexy/unpack if 'length >= blocksize'. For length < blocksize a_unpack~ zeros signal vector elements >= length and drops any additional lists that fall within the current block. zexy/unpack~ does the 'right thing' and includes elements from subsequent lists in the vector. Still a_unpack~ could be useful if you're like me and like to keep things as 'pure' as possible! Depends on list-abs for list-drip.

pack~ clone + a_blocksize~
by Jamie Bullock 22 Dec '08

22 Dec '08

Hi, Following my efforts to make pure Pd versions of some of the zexy essentials, I found some time over the weekend to knock together a pack~ clone. See attached. It seems to work OK, but like a_unpack~ posted recently it's horribly inefficient compared to the zexy original. It uses some other niceties: a_blocksize~ : reports the blocksize of the parent patch to its outlet a_pow2? : outputs 1 if the input is a power of two 0 otherwise Further contributions and refactoring welcome! Jamie P.S. requires list-rev and list-lastx from list-abs. -- www.postlude.co.uk http://www.linkedin.com/in/jamiebullock

[PD-announce] Pd-extended Intrepid package
by Ilias Anagnostopoulos 22 Dec '08

22 Dec '08

I have updated the Ubuntu Intrepid package for PD-extended and it no longer depends on any libraries that are not on the Intrepid repositories. The link has been updated on the PD page. Hans, if you had already uploaded the old one in the APT, can you change it with the new one? (Link: http://pd.ianagnostopoulos.postgrad.shef.ac.uk/pd-extended_0.40.3-intrepid6…) My 64-bit efforts are also postponed until mid-January, due to the Sound Studios moving to a new building. -Ilias _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

[templater] = Templates for Pd
by Luke Iannini 21 Dec '08

21 Dec '08

Hallo all! I think this is pretty cool - thanks to IOhannes' IEMguts, here is [templater]. Make and connect up some objects in a patch (for example, the common [f 0]X[+ 1] idiom) and save it as myobjects-template.pd somewhere in your pd path. Now, you can use [templater myobjects] to automatically construct and connect those objects within the current patch. There are two modes, relative and absolute, where relative spawns the objects just below the place where you created the [templater] object, and absolute just creates the objects exactly as they exist in the template file. I included two extremely simple templates to start things off (the oft-requested "metro with a toggle" and "f + 1 mod counter" idioms), but you can make the templates as complex as you like. The only current restriction is no subpatches, but I plan to remedy this shortly! I'd love it if anyone that tries this out posts their templates here - it could become a very nice way to share and refine pd idioms. The biggest drawback currently is that without ugly mouse-emulation hacks, there's no way for me to delete the [templater] object once it's spawned, so you have to do that by hand. Of course, it's still a ton faster than locating your template patch, opening it, selecting and copying its contents, pasting them, and closing the template. On that note, IOhannes, feel like making a [canvasdelete] object : )? (I of course don't know how easy/hard/safe this is) As mentioned above, [templater] requires IEMguts. I've included a build for Mac OS X Intel below. Best Luke

Re: [PD] undoing a dodgy cut and paste
by Matt Barber 21 Dec '08

21 Dec '08

I have avoided this by getting myself in the habit of moving stuff around with a shift-arrowkey rather than the mouse. It takes a second longer, but it's almost guaranteed to work (it also helps avoid that annoying problem you get when you paste something directly over what you just copied and you don't know which one you're grabbing with the mouse).

Possible to unselect radio buttons?
by Phil Stone 19 Dec '08

19 Dec '08

Is there any way to make there be *no* selection displayed in a radio button control? If not, this would be a very useful feature in that it would allow multiple banks of radio buttons to be tied together programatically. I.e., imagine a set of four hradio controls, stacked on top of each other. Any selection in any of the four becomes the current selection, but also turns off all other banks' selection indicators. Whereas a single 64-position radio control would be awkward to deal with graphically, 8 rows of 8-pos. hradio controls would be nice and compact. Phil Stone www.pkstonemusic.com
