Description
Brace yourself for a fun challenge: build a photorealistic 3D renderer from scratch! It's easier than you think. In just a couple of weeks, build a ray-tracer that renders beautiful scenes with shadows, reflections, brilliant refraction effects, and subjects composed of various graphics primitives: spheres, cubes, cylinders, triangles, and more. With each chapter, implement another piece of the puzzle and move the renderer that much further forward. Do all of this in whichever language and environment you prefer, and do it entirely test-first, so you know it's correct. Recharge yourself with this project's immense potential for personal exploration, experimentation, and discovery. The renderer is a ray tracer, which means it simulates the physics of light by tracing the path of light rays around your scene. Each exciting chapter presents a bite-sized piece of the puzzle, building on earlier chapters and setting the stage for later ones. Requirements are given in plain English, which you translate into tests and code. When the project is complete, look back and realize you've built an entire system test-first! There's no research necessary -- all the necessary formulas and algorithms are presented and illustrated right here. Dive into intriguing topics from fundamental concepts such as vectors and matrices; to the algorithms that simulate the intersection of light rays with spheres, planes, cubes, cylinders, and triangles; to geometric patterns such as checkers and rings. Lighting and shading effects, such as shadows and reflections, make your scenes come to life, and constructive solid geometry (CSG) enables you to combine your graphics primitives in simple ways to produce complex shapes. Play and experiment as you discover the fun of writing a ray tracer. Accept the challenge today! What You Need: Aside from a computer, operating system, and programming environment, you'll need a way to display PPM image files. On Windows, programs like Photoshop will work, or free programs like IrfanView. On Mac, no special software is needed, as Preview can open PPM files.

Let's be real: 2020 has been a nightmare. Between the political unrest and novel coronavirus (COVID-19) pandemic, it's difficult to look back on the year and find something, anything, that was a potential bright spot in an otherwise turbulent trip around the sun. Luckily, there were a few bright spots: namely, some of the excellent works of military history and analysis, fiction and non-fiction, novels and graphic novels that we've absorbed over the last year.
Here's a brief list of some of the best books we read here at Task & Purpose in the last year. Have a recommendation of your own? Send an email to ja...@taskandpurpose.Com and we'll include it in a future story.
Missionaries by Phil Klay
I loved Phil Klay’s first book, Redeployment (which won the National Book Award), so Missionaries was high on my list of must-reads when it came out in October. It took Klay six years to research and write the book, which follows four characters in Colombia who come together in the shadow of our post-9/11 wars. As Klay’s prophetic novel shows, the machinery of technology, drones, and targeted killings that was built on the Middle East battlefield will continue to grow in far-flung lands that rarely garner headlines.

Battle Born: Lapis Lazuli by Max Uriarte
Written by 'Terminal Lance' creator Maximilian Uriarte, this full-length graphic novel follows a Marine infantry squad on a bloody odyssey through the mountain reaches of northern Afghanistan. The full-color comic is basically 'Conan the Barbarian' in MARPAT. [Buy]
