RayTracing

This is a very basic raytracer and it is for learning purposes. This project is still in progress.

Threading to improve performance

Used this library to make a thread pool CTPL.

Basic config?

• Modify samples_per_pixel and max_depth with your prefered values, less values means better performance.
• Modify image_width and aspect_ratio with your prefered values.
• num_of_threads is the number of threads in the pool, choose a suitable number (Default: All available)
• lines_per_thread is the number of lines that each thread should handle (line is just a single row of pixels of the image width)

How to use?

to make the raytracer

make

to output the image, this redirects the program output to a file called image.ppm

make image

You can view the image using your any image viewer that supports ppm, if it doesn't support ppm below command to ouput a png image

make jpeg

• notice that this would make your CPU an inefficient heater, Mine got to 95C. and if you didn't use the optimizer it would take ages to finish.
