07:36 rogerm sup guys!
07:36 rogerm every thing allright?
07:36 rogerm http://i.imgur.com/3HFYoH3.png  this happens 'cos the oflight is doing vertex ilumination right?

11:02 tgfrerer rogerm: this happens most likely because you're using gourand shading - i.e. vertex positions are shaded, then the fragment shader interpolates between vertex colours according to the mesh tesselation.

12:09 HarryParky hi all
12:10 HarryParky i have a question about vector
12:10 HarryParky if I have a vett(x,y)
12:11 HarryParky how can I store the component of the vector in two different variable???
12:11 HarryParky something like this
12:12 HarryParky x= componentx_of _vector
12:12 HarryParky y= componentY_of_vectori
12:12 tgfrerer HarryPark: are you talking about geometry vectors, as in ofVec2f, ofVec3f ?
12:13 tgfrerer or c++ data container vectors as in vector<float> ?
12:13 HarryParky Yes ofVec2f or ofVec3f not array
12:13 tgfrerer cool, then:
12:13 tgfrerer x=myVec.x;
12:13 tgfrerer y=myVec.y
12:13 tgfrerer ofVec2f myVec = ofVec2f(2.,4.);
12:14 tgfrerer you'll get 2.0 for x
12:14 tgfrerer and 4.0 for y
12:14 HarryParky oh thanks so much tgfrerer
12:14 tgfrerer no worries =)

19:50 jvcleave vade - am around now
19:52 vade So, I did the RPI update, etc, but haven't pulled the new OF from master
19:52 vade I still get some issues with USB not responding, but the camera isn't crashing now
19:52 vade just the app sort of, takes over
19:54 vade I'm going to try the new build later
19:56 jvcleave do you have any other usb devices other than the camera (kinda sounds like a power issue)
19:56 jvcleave I typically use a powered USB hub for the PS3eye
19:57 jvcleave sometimes I can get away without it but then sometimes weird shit happens (like the ethernet going away)
19:59 jvcleave but it sounds like you got OF to re-compile
