Title:
Coding Adventure: Ray Marching
By: Sebastian Lague
Description:
Introduction to the concept of ray marching with some open available projects.
Overview
This video covers some of the basics of ray marching while also visualizing their approach and creating some interesting visual effects and renders with the math of signed distance along with ray marching logic. The major ray marching method they show is sphere tracing, which radiates circles/spheres out from a point until anything is collided with. Then, the point moves along the ray direction until it reaches the radius of that sphere projection and emits another sphere. This process is repeated until it radiates a very small threshold radius sphere, which is when a collision is determined.
The resulting project made is available, and I think it would be very useful and interesting to explore. The Youtube video description also holds many links to various sources used to create all the tools and effects in the video, which could also be beneficial for further research into these topics.
