11:06 radiodario is there a tutorial anywhere on how to apply normals + texture + specular to a sphere?
11:07 radiodario i'm trying to build an earth visualisation but i'm having little success
11:07 radiodario (my textures are upside down and backwards atm)
11:13 fuerstP joined #openframeworks
11:16 radiodario i tried following this example https://github.com/kalwalt/OFexamples/​tree/master/FractalFloatTerrainExample
11:21 radiodario sorry the gl_FragColor was set to alpha zero lol it works now
11:25 radiodario still my textures are back to front and upside down :/

11:28 kritzikratzi hey macos people!
11:28 kritzikratzi i’ve made a tiny tool to update xcode project files
11:29 kritzikratzi it can only add and remove addons
11:29 kritzikratzi so far it adds the src and include folders, and adds a line to the script phase, so that the data folder of the addon is copied
11:30 kritzikratzi ah, and it adds the .a files to the linker flags
11:30 kritzikratzi it’s not really a replacement for the project generator, just a quick hack if you need to add an addon, but want to leave the rest of your project intact
11:30 kritzikratzi code
11:30 kritzikratzi + binaries are here: https://github.com/kritzikratzi/ofxcode
11:30 kritzikratzi short demo here https://www.youtube.com/watch?v=t9fSUULIiDs

17:57 alski_ I am wondering, while performing rotations, when you specify axis, ((1,0,0) or something), is it just as simple as x,y,z? Or is there something more at play? I am looking at an example somebody has for yaw, and it involves (1,0,1), which actually brings me a little closer to my desired rotation...
17:58 lampd1 i think if you're just talking vec3f rotation you have degrees (x,y,z)
17:58 lampd1 and the negative and positive denote which way to turn around specified axies
17:59 lampd1 i'm still working on grokking quaternions/3d rotational transforms too though alski_
18:00 lampd1 working with a 3axis accelerometer is proving to be tougher than I was hoping :P
18:01 alski_ Do you think it's because of the serial parsing you were doing?
18:01 alski_ Or is it a matter of getting the angle and rotation just right?
18:05 alski_ Well, apparently while multiplying the three quats, the order in which you do it actually matters... I should have realized that earlier.
18:06 lampd1 i think it's more getting the angle and rotation just right
18:06 lampd1 yeah
18:06 lampd1 i think i need to work out my order of operations a bit more
18:06 lampd1 and use the proper methods
18:06 lampd1 you using setOrientation with your output quat?
18:07 alski_ getRotate, then ofRotate. Based on how it was being done in the quat arc ball example.
18:07 lampd1 i'm stuck either getting a reflection of accel movement but without rotation or getting the rotation angle in, but it never stops rotating
18:08 lampd1 within ofxeasycam?
18:08 lampd1 or is there actually a quat arc ball example
18:08 alski_ There is actually a ball example, in the 3d examples folder.
18:09 lampd1 cool, i'll check that out today once i can get back to this project
18:09 lampd1 was trying this https://gist.github.com/reidb​lomquist/4ceb1bd3d380a2c33c33
18:09 lampd1 that will get me the basic behavior i'm looking for, but never stops rotating
18:12 alski_ Have you checked to see if your accel data is acting the way you expect? Might be good to monitor all of that data if you aren't already
18:13 lampd1 yeah i have
18:14 lampd1 before i ever pulled the data into of i used a quick and dirty processing app to gauge the output
18:14 lampd1 and have been cout'ing data between what's set in of and what's being transmitted over serial
18:14 pizthewi_ joined #openframeworks
18:15 lampd1 hoping i can understand things a bit better by EOD today, but have a bunch of other stuff to work on :P
18:16 lampd1 have you done much w/ data in OF/C++ - thinking i'm going to be indexing some data to models/meshes and just kind of tossing the idea around and trying to pick a DB engine
18:16 lampd1 was probably just going to roll w/ mysql or something as a test
18:17 lampd1 suppose i could just write to xml
18:17 alski_ Ah, awesome. Yeah, for me these things have worked well in the juggling act of my other projects. I'd like to see how you would get it set up with mySQL, I haven't seen anything with DBs and OF.
18:19 alski_ if I ever end up having to use mySQL in OF, my work and my art will stop being separate haha.
18:35 pizthewiz joined #openframeworks
18:37 lampd1 ;)
18:37 lampd1 I'm playing with OF for work
18:37 lampd1 prototyping an idea
18:37 lampd1 tbh it's nice when you can make both worlds meet and get paid to make art ;)
18:39 alski_ Oh yeah, I would love more of that. I am a web programmer for a university, so the programming becomes a little less spectacular, OF lets me feel more passionate about programming.
18:40 alski joined #openframeworks
18:41 lampd1 ah, cool - I'm an engineer at an agency and was recently tasked with doing some R&D/exploration in my "down time" :P
18:41 lampd1 haven't worked with C++/C# in years till a month or so ago
