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.
raycast width height /path/to/config.json /path/to/output.ppm
width: The width (>0 pixels) of the output imageheight: The height (>0 pixels) of the output imagejsonFile: A valid path, absolute or relative (to pwd), to the config json file.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.
make: Compiles the program into out/ as out/raycast
make clean: Removes all object code and the out/ directory altogether
- Because make compiles
raycasttoout/, in order to run it properly it should be used asout/raycast width height /path/to/config.json /path/to/output.ppm. - The output file should contain the line/comment "# Created with raycast (Christopher Philabaum <cp723@nau.edu>)" following the magic number.
