• In shading calculation, when you need a texture value you perform a texture lookup • Convert (u, v) texture coordinates to (i, j) texel coordinates, and read a value from the image – simplest: round to nearest (nearest neighbor lookup) – various ways to be smarter and get smoother results • What if i and j are out of range?

Ray Tracing: Texture Mapping

https://ray-tracing-conept.blogspot.com/2015/01/texture-mapping.html

Algorithm: The easiest way to texture map onto a sphere is by defining v to be the latitude of the point and u to be the longitude of the point on the sphere. This way, the texture image will be "wrapped" around the sphere, much as a rectangular world map is wrapped around a globe. Figure 8. Mapping a rectangular world map onto a globe. Figure 9.

I have set up a simple ray tracing in C++. I wanted to add the texture mapping to the sphere. It basically just map the texture from a PPM file to the sphere. Below are my code for the part. //Call shaderay from trace ray function // index_of_winning_object = index of scene object array // point = intersection point Color shadeRay (int index_of ...

Introduction. A new article of our ray-tracing series describes how to apply texture images on triangles. The process is based on R 2 and R 3 points distance calculations and its proportions, using again the method tAlgebra.GetCoord already known from the last articles.. We have. 2 triangles formed by 3 points in R3 each: P1, P2, P3

Recursive Ray Tracing • The classic ray tracing algorithm includes features like shadows, reflection, refraction. • A single primary ray may end up spawning many secondary and shadow rays, depending on the number of lights and the arrangement and type of materials • These rays can be thought of as forming a tree like structure
