C 3D-Projection

Warning: This project is still a WIP and not totally finished

This project is a simple 3D "engine" written in C for the Blackbox YSWS, which is centered around the theme constraints. It's a device with a resolution of only 8x8 pixels. The math is similar to my Python 3D projection projection.

Features

• Projection: Matrices for projection onto the display
• Rotation: Quaternions for rotation of the camera to avoiding gimbal lock.

Note: Currently using direct rotation matrix manipulation as a temporary fix!

Difficulties

These are a few of the technical difficulties I faced while working on this project. These features were not supported by the Blackbox editor at the time I wrote my code:

• No console for debugging:
• No external libraries: External libraries are NOT allowed, this project was made without:
• • math.h: sin(), cos(), pow(), sqrt()
• • stdlib.h: malloc(), realloc(), calloc(), free()
• No pointers: There are issues with * and &, no pointer were used
• No arrays
• No structs
• No function prototypes: Function prototyping does not seem to work
• No typecasts: ToInt() function had to be implemented
• No preprocessor directives: Don't seem to work
• Others: Some other convenience features of the C language are also not usable

How to Run

Option 1: You can access the project here on the Blackbox website. Warning: No longer works as the editor was updated.

Option 2: Copy the main.c file. Paste it into the editor.

Controls

• Arrow Key Up: 1: Move forward 2: Move Up
• Arrow Key Down: 1: Move backward 2: Move Down
• Arrow Key Left: 1: Move left 2:Look left
• Arrow Key Right: 1: Move right 2: Look right
• X: Switch between 1 and 2

To-Do

• Potentially add sound Won't be done unless I upgrade to the newer editor version
