Visualization Lecture 11.2. Ray Casting, Ray Functions, Transfer Functions, Direct Volume Rendering

Here we introduce several topics and terms including: ray casting, ray functions, classification, transfer functions, gradients, 1D
transfer functions, 2D transfer functions, gradient-dependent
transfer functions.
Ray functions include: maximum intensity projection (MIP), compositing, x-ray, first hit

Thank you so much for this video! I was very lost in my professors lecture for this topic as I had never dealt with anything like this but I found this video and it is a perfect! You are awesome!

I love your videos! Never dreamed I'd find another professor doing very similar content... A suggestion could be to mark in the comments of the video where each main topic comes up so we can click when we are reviewing for exams and such or just need one quick concept
:D

Almost clear about Transfer function, opacities role and thanks for the outstanding slides and way of teaching. :)
Regarding front-to-back vs back-to-front ray casting, which one is better and why?

I thought raycasting/tracing had to do with a point at the origin (0, 0, 0) and the vector representing the direction to each pixel...

Difficult to hear when you walk to the projection.
