raycast is a software-renderer-based raycaster that takes in an indefinite amount of scene objects such as planes and spheres provided by a JSON file, and outputs the scene as a P6 PPM image file.

Note:

• This program chooses to output the PPM file as a P6 raw binary format.

Usage

raycast width height /path/to/config.json /path/to/output.ppm

parameters:

1. width: The width (>0 pixels) of the output image
2. height: The height (>0 pixels) of the output image
3. jsonFile: A valid path, absolute or relative (to pwd), to the config json file.
4. outputFile: A valid path, absolute or relative (to pwd), to the output ppm file.

All parameters are required and not optional. All parameters must be used in the exact order provided above.

Compile

make: Compiles the program into out/ as out/raycast

make clean: Removes all object code and the out/ directory altogether

Grader Notes

• Because make compiles raycast to out/, in order to run it properly it should be used as out/raycast width height /path/to/config.json /path/to/output.ppm.
• The output file should contain the line/comment "# Created with raycast (Christopher Philabaum <[email protected]>)" following the magic number.
