Christmas Day (music box)


Christmas Day is a free Palm OS™ software, working like a 3D animated music box. While the 3D scene is rendered, some Christmas songs are played in background.

The Story

I've always been fascinated by the 3D graphics. In 2008 I decided to learn more about the technologies used for 3D rendering (math for 3D transformations, algorithms used to fill polygons with a texture, algorithms used for applying light on surfaces such as Gouraud and Phong, and so on), then I wrote my first 3D rendering engine based on ray casting (Delphi language). The following month, I decided to use it for applications running on Palm OS and I started porting the code in C (ARM code). Since then, I've never used this code for any type of application because I found it too slow to render 3D scenes in real-time on devices running Palm OS. Finally, I've decided to use it to create an application using the 3D rendering and playback of MIDI music: a music box for Christmas. It has been a very exciting experience!
