<0> So, are you saying when applying the quaternion to a child, add the translation of the parent to the quaternion first??
<0> I didn't think translations could be added to quats
<1> You're not adding it to the quat
<1> a rotation is a rotation
<0> right..
<1> q1q2 <= the new rotation
<1> + t1q2 + t2 <= position
<1> so you rotate t1 by q2 then add the new offset
<1> just like you would with matrices
<0> hmm.. ok.. I'll try a few things, you going to be around a while?
<1> Hm. Perhaps. But very off-and-on
<1> If I'm not around I apologize in advance. I have to get a shared memory GL client/server app coded tonight.
<0> lets go through a couple quick cases to make sure I understand..
<0> Say I have 1 joint.. Currently, I set its position to origin, apply quaternion, set its position back to where it should be.. that works fine
<0> Now, if I go to joint2 which is attached to joint 1, I p*** joint2 joint1's rotation quat, but you're saying I should also p*** the position of joint1 to joint2 to apply to it after I rotate it?
<1> you'll need the position and rotation of the joint1 node
<1> so yes
<1> you have q1 and t1 from joint 1
<0> ok.. now if I get the joint3, which is attached to joint 2 (joint1->joint2->joint3), and rotate joint1 .. So, I p*** along rotation and position to joint2 to add to its position.. Then, I p*** joint1 + joint2's position to joint3 (as well as joint1rot * joint2rot)
<1> yeah
<0> ok, cool, I'll give that a try
<1> as far as i did the quick math, anyway.
<1> :)
<0> thanks. I'll let ya know how it goes
<1> cool
<1> if you're still having trouble the guy to talk to would probably be return0
<1> he wrote animadead
<0> thanks
<1> oh, also : http://www.devmaster.net/forums/showthread.php?t=4590
<1> Looks like someone else has done the same thing.
<1> :P
<0> heh, yep
<0> Still there dr nick?
<0> Here's what I'm trying to do based on what you said: boneOrientation.setPosition(queuedParentRotations.multiplyVector(bonePosition)).add(queuedParentTranslations));
<0> the child joints shoot off the screen...
<2> right to da moon?
<2> just p*** the matrix
<2> you gotta rotate the last point anywayz
<0> eh/
<0> ?
<3> WHAT IS THE MATRIX
<2> you need to rotate your point by the sum rotation before you add it to the total translation
<2> and you need to rotate it around the rotated point from the last translation
<3> that's what they did to neo
<2> StoneCyqh: the Matrix is some craq.... here, go smoke some
<3> i don't do craq, i do smaq
<2> smaq, craq, it's all for da thwaq
<4> the poo nevar endz in the matrex
<2> Oblivion is the current form of the Matrix
<3> Uh Buh Guh Duvion
<2> StoneCyqh has obviously smoked teh smaq
<3> hence, on my arm, the traq
<1> anyone here know where to find values for mode_t (posix)
<2> RTFM?
<1> yeah, if there was one
<2> ;D
<2> posix has no manual?
<1> its a standard
<1> there's probably an iso spec for it somewhere
<2> yah
<1> yeah. googles not so helpful
<0> dr nick
<0> see what I'm trying to do? I"m a little confused about the T1 and T2 in the equation...
<0> hrm, no idea about mode_t
<2> http://ecos.sourceware.org/docs-2.0/ref/posix-files-and-directories.html
<2> not so terrific
<1> :D
<2> they must not think anyone uses posix ;)
<1> heh
<1> yeah, you know. not 3/4 of the world or anything.
<2> exactly
<2> that's why they leave it up to the reader to decide what it means
<1> curmo - bone.setRotation(q1*q2); bone.setPosition( t1*q2 ).add( t2 );
<2> you doing file operations? or am I in a totally different place
<1> Ghaleon - err yes but only because a shared memory object is represented by a file descriptor
<2> it says some of the functions ignore the mode
<1> So I've got my shared memory stuff working with shmget
<1> but I'd like to use shm_open and go Posix instead of system v
<2> http://www.gnu.org/software/libc/manual/html_node/Testing-File-Type.html
<2> that might be able to help
<1> hrmmm
<1> thanks
<1> that linked to this :
<1> http://www.gnu.org/software/libc/manual/html_node/Permission-Bits.html#Permission-Bits
<1> and thats what i need
<2> yah
<1> ah. ok this is simple enough
<1> sweet.
<1> Hrm.
<2> sweet, the sticky bit means completely opposite things on some systems
<2> way to be compatable
<2> how can a game damage a monitor...
<2> Quake 4 patch 1.1 recalled
<5> ?!
<5> Quake 4 1.1 patch can damage monitor?
<5> LOL
<5> how?!
<2> I don't know!
<2> says it can damage widescreen monitors
<4> lol wtf?
<3> uh
<3> i haven't heard of a monitor that attempts bad inputs since the cga era
<3> back way way back in teh day, on Pc Jr., there was an early virus which set the vertical refresh to several hundred hertz
<2> maybe a cga widescreen monitor? it was so before its time
<3> and ancient primitive man's flint-and-animal-skin CGA monitors just said "hur hur okay i'll try that"
<3> fires occasionally ensued
<2> that'z my mess
<3> and i mean
<3> don't get me wrong, i'm all for the virus hate
<3> but a virus that can actually catch your **** on fire
<3> you've just got to respect that
<3> EGAD
<3> MY ****
<3> I WAS IN THE CAN TAKING A ****
<3> AND IT CAUGHT ON FIRE
<3> AND NOW MY *** IS ALL BURNED
<2> pwnzd
<3> THANKS A LOT, GHALEON
<2> teach u to eat fire
<3> YOU RUINZED DA BAQ
<2> apparently Quake 4 doesn't properly detect resolutions / refresh rates
<3> well, the windows driver is supposed to put up the hand what says halt
<3> so it's technically the driver's fault, not quake's
<3> though, that is a significant gaying of quake's record
<2> Quake 4 ****ed either way really
<2> ;D
<2> I just think it's pretty lame of it to be like dat
<2> trying to figure out why it can bust monitors
<2> I wonder if they mean widescreen TV's used as monitors
<2> cuz like all widescreens I've seen are LCDs

<4> lol
<4> wheres a link to the story about the Q4 patch
<2> I only saws it on GlideUnderground
<2> so I'm guessin it was an emails sent out to registered owners of Q4
<5> bloody hell
<5> Ants made a nest inside my scanner
<6> thats ghetto dude
<6> who does that
<7> Dr_Rambo: hehe, one of my coworkers had his laptop infested with ants on a trip to the philippines a few years ago, thousands of them
<4> lol
<4> DUDE
<4> press scan
<4> i wanna see it
<6> gross man
<4> lol
<6> ants are cool species though
<4> so is your mom
<3> huhhuhu
