Ray Tracing | NVIDIA Developer

Ray casting is the process in a ray tracing algorithm that shoots one or more rays from the camera (eye position) through each pixel in an image plane, and then tests to see if the rays intersect any primitives (triangles) in the scene.

The ray that travels parallel to the optical axis refracts so that it appears to be coming from the focal point on the object’s side of the lens. The ray that travels through the center is not deflected. The ray that would pass through the focal point on the far side of the lens refracts to become parallel to the optical axis. The Optical Axis

Tracking every light ray from the light source down means that many rays will go to waste because they never contribute to the final image as seen from the eye. Forward ray tracing is also known as light ray tracing and photon tracing. Backward Ray Tracing To make ray tracing more efficient, the method of backward ray tracing is introduced.

Full Ray-Tracing • For each pixel – Compute ray direction – Find closest surface – For each light • Shoot shadow ray • If not shadowed, add direct illumination – Shoot ray in reflection direction – Shoot ray in refraction direction Dielectric if (pis on a dielectric) then r= reflect (d, n) if (d.n< 0) then refract (d, n, n, t) c = -d.n

Draw the refracted ray at 0 degrees (i.e., trace the incident ray straight through the first boundary). At the second boundary, the normal line must be drawn (labeled N) and the angle of incidence (between the incident ray and the normal) must be measured. This is shown on the diagram at …

https://www.physicsclassroom.com/class/refln/Lesson-3/Ray-Diagrams-Concave-Mirrors
Pick a point on the top of the object and draw two incident rays traveling towards the mirror. Using a straight edge, accurately draw one ray so that it passes exactly through the focal point on the way to the mirror. Draw the second ray such that it travels exactly parallel to the principal axis.
Ray Diagrams for Lenses - Georgia State University
http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/raydiag.html
Ray Diagrams for Lenses. The image formed by a single lens can be located and sized with three principal rays. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length. The "three principal rays" which are used for visualizing the image location and size are:
