Title: ScreenResolution and AspectRatio
Post by: va!n on July 29, 2010

I have a generall questions when it comes to think about the ScreenResolution and AspectRatio for creating 2D only, 3D only stuff...

In the past i used a 4:3 resoultion like 640x480 or 800x600... Since i have a Widescreen TFT, this resolutions looks bad on the TFT (left and right a black border... or the resoltion is stretched, where a circle looks like oval :(

So the question is, what is the best resolution (aspect ratio) to create the original scene (2D like Tilemapping or just a full 3D scene) that fits nice on 4:3 and on any other WideScreen resolution, so a circle still looks like a circle... and just only having possible black borders on top/button if needed? (depended on the user selected resolution for the game/demo)

Thanks for any infos and hints / tips to manage this in a nice and easy way...



Edit:
I thnk its a lot harder to get this work for 2D stuff only.... When having 3D only stuff, i think you have just to change the cam view!?

There are a few ways you can deal with it, but no perfect solution.
In my personal order of preference...
1) detect the aspect ratio of the screen (code here) (http://www.dbfinteractive.com/forum/index.php/topic,4751.msg63818.html#msg63818)
then change your render aspect ratio.  In LoMeDux it means that 4:3 users actually see less at the sides of the screen than 16:9 users.
2) render at 16:9, and letterbox top and bottom on 4:3 screens
3) render at 4:3 and pillarbox left and right on 16:9 screens

That's quite doable but your artist will kill you for that ;)
Imagine the screen content was designed to meet horizontally at the golden ratio (http://en.wikipedia.org/wiki/Golden_ratio) of 1,618:1.
When cropping the image horizontally from 16:9 to 4:3 the proportions end up at almost 2:1.

Are these the same artists that think 48, 257 and 255 are powers of 2? :P
