- Ray Tracing in One Weekend (raytracing.github.io)
I’ve taught many graphics classes over the years. Often I do them in ray tracing, because you are forced to write all the code but you can still get cool images with no API. I decided to adapt my course notes into a how-to, to get you to a cool program as quickly as possible. It will not be a full-featured ray tracer, but it does have the indirect lighting which has made ray tracing a staple in movies. Follow these steps, and the architecture of the ray tracer you produce will be good for extending to a more extensive ray tracer if you get excited and want to pursue that.
- Washington Pass (wa100.dnr.wa.gov)
Washington Pass—accessible only about half of the year—is a stretch of the North Cascades Highway boasting steep mountains, year-round glaciers, and a gorgeous alpine forest. This section of State Route 20 climbs to elevations over 5,500 feet and is covered by up to 40 feet of snow between late Fall and early Summer. A short side road near a hairpin turn leads to the Washington Pass Overlook, where visitors can enjoy a short paved trail leading to a spectacular viewpoint. Looming above the overlook are the slopes of a breathtaking array of alpine peaks and pinnacles, including the rounded dome of Liberty Bell and the twin peaks of the North and South Early Winter Spires. This landscape is immensely popular with rock climbers, who scramble up the sheer slopes to reach high vantage points with views of Kangaroo Ridge to the east and the glacier-carved Methow River valley to the north.
