Hi Willem; I guess I'm confused as to what you're saying here, so perhaps you can elaborate?…
I need to work between the two modes constantly. In order to convert an angular measurement in degrees into a unit vector, and vice versa, I sure do need to use radians. If you know of another way to do this, then can you share?… And, as I said, in order to stay sane while working with the code for vectors associated with objects and their rotation in an engine, I definitely need to use angular measurements in degrees. So what am I missing here? Yes, there's a lot of converting going on, but without using radians, I know of no other way to move between an angle in degrees and it's associated unit vector. Thanks so much and do have a lovely day!… Smiles, CQ :) On Dec 13, 2010, at 12:28 AM, dwill...@gmail.com wrote: I think there is too much converting back and forth. When debugging you can convert the angle before displaying, but besides that there is no need to have angles in degrees. The developer never really has to work with the radians. -original message- Subject: Re: [Audyssey] game objects in memory From: Cara Quinn <caraqu...@draconisentertainment.com> Date: 13/12/2010 10:10 am Willem; Not quite true, unless I'm not understanding you properly… We're not actually talking about any angles being displayed to the user here but working with angles in the engine itself, and interpreting those angles either explicitly or relatively to show / affect the placement / orientation of game objects as well as some behind-the-scenes uses in game play for the user. I.e. aiming and such. So the user will most likely only ever be aware of the actual angle an entity is facing in context of a compass heading. This is purely for the comfort of the developer so we can more easily work with game code and not lose our bloody minds doing so!… lol! -Know what I mean?… It's a whole lot easier working with 30 degrees rather than 0.5235987756 radians, yes? lol! Have a totally awesome night and hope the holidays are treating you and yours wonderfully! -Thanks for the great notes keeping this way cool topic happening!… Smiles, Cara :) On Dec 12, 2010, at 8:24 PM, dwill...@gmail.com wrote: Yes, but the actual value doesn't matter as long as you stick to using one or the other method. Under normal surcomstances it wont be shown anyway and only the angles that are displayed need to be converted. -original message- Subject: Re: [Audyssey] game objects in memory From: Cara Quinn <caraqu...@draconisentertainment.com> Date: 13/12/2010 1:53 am Hi Willem, right you are! -For me though, holy crap! I wouldn't feel at all comfortable dealing in radians all the time. lol! I prefer to work in degrees and just convert back and forth on the fly. I basically have two methods I send pointers to; one to get an angle which returns in degrees, and the other to set an angle which takes degrees. I personally just don't naturally think in radians, but there ya go. Have a terrific day!… Smiles, Cara :) On Dec 12, 2010, at 9:28 AM, Willem Venter wrote: Hi Cara and all. Thanks for the discussion. Reading all this was very informative and helpfull. An observation I might make is that if you work only in radians, multiplying and dividing with the constant (pi/180) becomes redundent. This will save some small calculation and simplify the code. If you really want to see the normal degree form of the angle you could just use standard functions to convert it back for displaying.
