I'm taking a masters degree in informatics engineering, specifically in the areas of computer graphics and applications engineering at University of Minho, Portugal. I like digital arts and graphic design - http://cargocollective.com/joxnas - and I play guitar in my spare time. Occasionally I write a post in my blog too: http://imagine-random.blogspot.pt

comment Setting density for Android game
I never used canvas so I can't probably help you. In opengl you normally just need to care about the coordinates of things in the 'opengl world' . But one more thing, are you trying to achieve the same speed in terms of real world measures in all screens? Like 1inch per second? Cause its the only reason I see for using dpi here... If that's what you want its a little strange... Why would you need that instead of using the more common pixels per second, or even better, coordinates on which you abstract the notion of pixel..?

Just to make it completely clear, you aren't using opengl are you? And, when you talk about different performance, you mean different speed right? Cause it's not the same thing...

Your camera rotates around 1 or 2 axis? My answer only takes into account rotation around a single axis. I'll create an illustration of it.

@Larolaro I've added a graphical demonstration to my answer so you can understand it a little better.

I can provide the conditions and solutions with the multiplication sign (*) so it is easier for you to port them to your programming language (Then you would only need to replace the ArcTan[...],Sin[...],Cos[...],Sqrt[...] and eventually the power sign (^).
