The edited chat transcript of this lecture is below: October 19, 2020 12:00 PM from ilkim oğul to everyone: how does it determine when it doesn't hit anything? is there a boundary to the space or a length llimit for the ray? October 19, 2020 12:00 PM from Anas Osman to everyone: If we want to make the camera a fisheye, do we curve the image plane into a spherical sector or is the image plane always a 2D shape? October 19, 2020 12:03 PM from Bugra to everyone: Will we reflect the ray when it touch a object? October 19, 2020 12:03 PM from Bugra to everyone: an object* October 19, 2020 12:06 PM from Anas Osman to everyone: How are objects made of transparent materials like water or glass traced? October 19, 2020 12:06 PM from Bilal Said Duman to everyone: is it expensive to cast shadows? October 19, 2020 12:06 PM from Tolga Can to everyone: refraction October 19, 2020 12:09 PM from Bugra to everyone: No there can be another object in front October 19, 2020 12:12 PM from Bugra to everyone: If an object has a lot of triangles we intersect the ray with all of them one by one right? October 19, 2020 12:13 PM from Anas Osman to everyone: Are the aperture, ISO, shutter speed/framerate, etc adjustable in the camera like a real one? October 19, 2020 12:14 PM from ilkim oğul to everyone: are we technically tracing the rays from the light sources that happen to hit both the focal point and the image plain like our eyes do, or do the rays originate from the focal point in way that is possible only virtually? October 19, 2020 12:22 PM from Tolga Can to everyone: uxv October 19, 2020 12:28 PM from ilkim oğul to everyone: is there any reason to not do that? other than wanting multiple cameras? October 19, 2020 12:30 PM from Bugra to everyone: isn't it more expensive in terms of computation October 19, 2020 12:30 PM from ilkim oğul to everyone: have multiple cameras and switch between them real quick to make it look like movement. October 19, 2020 12:30 PM from Anas Osman to everyone: Can the world coordinates move to produce certain effects? October 19, 2020 12:33 PM from Anas Osman to everyone: But since the position and size of the camera and the image plane depend of the world coordinates, changing or moving them should have no effect on the produced image right? Unless the camera is linked to another set of world coordinates October 19, 2020 12:34 PM from Anas Osman to everyone: Understood, thank you sir
