Implementing a Path Tracer so that I can teach myself the Go language.
Now with more concurrency! ✨
Following the E-book by Peter Shirley 'Ray Tracing in One Weekend', but in Go instead of C++.
I also wrote a series of posts chronicling the process on my blog.
$ ./bin/go-trace -help
Usage of ./bin/go-trace:
-a value
camera aperture (default 0.010000)
-cpus value
number of CPUs to use (default 8)
-fov value
vertical field of view (degrees) (default 75.000000)
-h value
height of image (pixels) (default 500)
-n value
number of samples per pixel for AA (default 100)
-o value
output filename (default out.png)
-version
show version and exit
-w value
width of image (pixels) (default 600)
-x float
look from X (default 10)
-y float

-z float

$ make
go build -o bin/go-trace github.com/markphelps/go-trace/cmd/go-trace
$ ./bin/go-trace
Rendering 600 x 500 pixel scene with 486 objects:
[4 cpus, 100 samples/pixel, 75.00° fov, 0.01 aperture]
[==========----------------------------------------------------------------------] 12.80%
$ make test
The default output format is PNG and the default filename is out.png.
This can be changed by using the -o flag as described in the help output.
Ex: $ ./bin/go-trace -o output.jpeg
Current supported file extensions:
- .png
- .jpg
- .jpeg
