A week ago, PixelAndPolygon went live. There’s a link on the page to download an early beta of Pico Pixel.
The beta version supports bmp, jpeg and png texture formats. The program relies on Windows native libraries to read these formats. Support for DxT and BCn textures is being planned.
The web site is still in construction, but this is a good time as any to try Pico Pixel. You will need a GPU with driver support for OpenGL 3.0. All GPUs from NVidia and AMD are good to go.
Intel’s driver fails to render Pico Pixel window properly. Reverting to regular window borders for this driver could be a solution.
