Over the past few months (off and on), TIny and I have been working on a 16-bits per pixel graphics library for the CE C toolchain. The library uses column-major mode to avoid screen tearing, and allows for logical frames by enabling / disabling framebuffer copies. This is particularly useful given the lack of a buffer when in 16-bpp graphics modes. Here's a list of some of the currently finished routines:

• Set/GetPixel
  
• Rectangles (filled, outline, clipping)
  
• Lines (horizontal, vertical, regular, clipping)
  
• Circles (filled, outline, clipping)
  
• Sprites (transparent, scaled, regular, clipping)
  
• Text (colors, scaling)
  
• A few other things (here's a full list)
  

Here's some eye candy as well:

Feel free to drop any suggestions for routines we should consider including in the library before release

Also thanks to calc84maniac for giving us some guidance when working with display modes!

Nice work guys, this is awesome

Nice work

Also a whole bunch of screenshots and not one showing 16bpp graphics

Interesting, good job!

Here's some fun color gradients (generated using the algorithm from Michael2_3B's color gradient generator):

This looks very promising. The gradients look great, I'm definitely not used to that sort of color fidelity coming from a CE screen haha.

Is this fast enough to be used for games and other real-time applications, particularly relatively complicated ones such as Oiram? Are you aware of a specific consistent point in which it noticeably begins to struggle? Seeing as this is all programmed in assembly, I assume it's reasonably well-optimized enough for most typical use cases.

Definitely going to try my hand at making a Processing-like tool using this. A live code sketch editor for the CE seems like a fun idea to try.

Oof data sizes lol!

But seriously this is great work, HQ visuals calc speaking for sure .

Maybe something like Myst would be a good use of this? (Though you might need the help of a USB drive).
