Any tricks to make 2D graphic looks much better?

Recommended Posts

I am fresh new in 2D graphics so what I can do now is just copy the image files to the screen... I am wondering if there are some software approach to enhance the visual quality beyond that? I remember in some snes emulators there are cool effect such as bump mapping. I am also thinking using normal map. But without hardware support and APIs (e.g. DirectX), I found I am really nothing... :( Sum up, my question is: are there any special effects or tricks to make an 2D image looks better, using only software algorithms, and can run in real-time(such as on a GBA)? Many thanks!

not really much you can do with 2d graphics,
some anti-alsing like smothing between objects,
also paralax backgrounds and some semitransparencey over multiple layers

Thank you relsoft! the demos are really instructive.
I am also interested in post-process on bitmap files, such as
add bump effect, or makes the picture looks "lighted". Are there
any good examples?
On a second thought, maybe I could just make the image looks
"bumpped" in photoshop, and just copy the final image to screen...

For best results, assuming you don't want realtime effects, yes. Bumpmapping using a 3rd party sofware is the best way to go. But if you wan't your title screen to look cool with multiple lights, a 2d bumpmapping algo would be the way to go. This one I made with BASIC(FreeBASIC.net) when it was still a closed beta(I was a beta tester) and I used graphics effects to find out lots of bugs in the compiler.

Bumpy

Enjoy. :*)

I could convert this to C/C++ anytime though.
