Writing a Ray Tracer in Go - Part 5

This is the 5th and final post of my series on writing a ray/path tracer in Go. Check out the previous parts 1, 2, 3 and 4. I’m roughly following the e-book Ray Tracing in One Weekend, but translating all of the code into Go. All of the code for this post can be found on my Github. Last time we added metal and matte materials, giving us the ability to render the following image: »

Writing a Ray Tracer in Go - Part 4

This is part 4 of my series on writing a ray/path tracer in Go. Check out parts 1, 2 and 3. I’m roughly following the e-book Ray Tracing in One Weekend, but translating all of the code into Go. All of the code for this post can be found on my Github. Last time we added the ability to shade our sphere and added anti-aliasing to make everything look better. »

Writing A Ray Tracer in Go - Part 3

This is part 3 of my series on writing a ray/path tracer in Go. Checkout parts 1 and 2. I’m roughly following the e-book Ray Tracing in One Weekend, but translating all of the code into Go. All of the code for this post can be found on my Github. Last time I covered the basics of creating rays, spheres and calculating if a ray intersects a given sphere. In order to visualize our sphere, last time we colored a pixel red if a ray intersected it and some shade between blue and white if it did not. »

Writing A Ray Tracer in Go - Part 2

This is part 2 of my journey to try and write a ray/path tracer in Go. Checkout part 1 here. I’m roughly following the e-book Ray Tracing in One Weekend, but translating all of the code into Go. In the previous post we covered how a path tracer works and got an image to display on the screen by blending red, green and blue into a cool looking gradient. This time around we’ll draw a sphere instead, but by actually sending rays into the scene and marking the pixels where they hit the object. »

Writing a Ray Tracer in Go

I’ve been wanting to learn Go for awhile now. I bought a book, read several blogs and tutorials, but I still didn’t feel like I was really getting anywhere with the language. A few weeks ago I went with my a few of my co-workers to the Triangle Golang meetup hosted by my friend Brett, and met some great people. One of the guys demoed an amazing project he had worked on, building a ray tracer in Go. »
