# Multithreaded Ray Tracer
|
||
|
||
## Ray Tracing in One Weekend
|
||
|
||
This project is an implementation of Peter Shirley’s
|
||
[*Ray Tracing in One Weekend*](https://raytracing.github.io/books/RayTracingInOneWeekend.html),
|
||
the first book in the Ray Tracing trilogy series, written in C++.
|
||
|
||
In addition to single threaded implementation, I've added multithreading to keep the render time reasonable.

## Performance Benchmark
|
||
|
||
My CPU is Intel Core i9-13900H with 8E and 6P cores (20 logical threads). The above image was rendered in about 5m 20s with all of the logical threads saturated and CPU utilization at ~95% with a base clock of 2.8GHz. The image consists of 500 samples per pixel, 50 Max recursion depth at 1200 x 675 resolution. The original PPM image was converted to PNG format using ImageMagick.

||
| Mode | Render Time |
|
||
|-------------------|------------|
|
||
| Single-threaded | 2 hours 59 minutes |
|
||
| Multithreaded | 5 minutes 20 seconds |
