Figure 1: backward or eye tracing consists of tracing rays from the eye through the center of each pixel of the image. If the ray intersects an object from the scene, the colour of the pixel the ray is passing through is set with the color of the object at this intersection point.

Ray tracing generates computer graphics images by tracing the path of light from the view camera (which determines your view into the scene), through the 2D viewing plane (pixel plane), out into the 3D scene, and back to the light sources.

I think the mistake is here: vec3 dir = look_at – eye + xp*u + yp*v; The image plane should have a normal vector w, and either be between the eye and the look at point (the more common way in ray tracers), or be behind the eye (more closely models an actual pinhole camera).So let's create a scalar zoom_factor.A positive number will put the plane in front of the …

6 I am currently working on ray-tracing techniques and I think I've made a pretty good job; but, I haven't covered camera yet. Until now, I used a plane fragment for view plane which is located between (-width/2, height/2, 200) and (width/2, -height/2, 200) [200 is just a fixed number of z, can be changed].

Ray Tracing and Camera Views - General Q & A - …

I am very perplexed by the lack of light in the interior physically based ray tracing camera. They always appear to be taken with all the interior lights off. What I have tried so far: - adjusting the camera exposure and brightness. - adding lights and light sources. - increasing the maximum number of lights on. - adjusting the sun angle, etc.

2 Ray Tracing in the real world Light is emitted from light source Bounces off of the environment Assumptions Light travels in straight rays Path of light changes based on object interaction. Can simulate using basic geometry. Some light will reach and be focused by camera onto film plane. Lots of light will not! In image synthesis, we are only interested in the
Unity - Manual: Rays from the Camera
https://docs.unity3d.com/Manual/CameraRays.html
Raycasting The most common use of a Ray from the camera is to perform a raycast out into the scene A Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
