Ray tracing - texture and phong lighting - Stack Exchange

1 Answer1. Show activity on this post. I don't exactly understand how would ray-tracing change anything, here is how it usually goes: You can have a texture for any parameter you like, but the most common is a diffuse (color) map, so you just sample this based on the texture coordinates and use the texture in place of the single-color diffuse.
"Specular" color with phong shading and raytracing …

Vec3f reflected = light_ray_dir - 2 * (light_ray_dir * hit_normal) * hit_normal; where light_ray_dir is calculated as: Vec3f light_ray_dir (current.pos - intersection); With current being the name of the light_source and intersection being the point of encounter of the ray with the triangle. It always worked fine when it did only diffuse light.

Chapter 3 Ray Tracing 3.1 Local vs. Global Illumination

The Phong lighting model that we discussed in the previous chapter is called a local illu-mination model. In the model, the shaded color or the illumination at a point of a surface ... To follow the paths of light rays, ray tracing makes use of the characteristics of light: 1.Light rays travel in straight lines. 2.Light rays do not interfere ...

What is the difference between all these techniques? I know what a lightning model does, eg Phong, Flat, Gouraud. As far as I know both Ray Tracing and Global Illumination are just lighting models different from the classic ones mentioned above that simulate physical light more accurately, taking into account light ray bouncing, indirect light etc.
