I am trying to plot the phase shift of perpendicular and parallel waves with variable angle of incidence, 0 to 180 degrees. The waves are travelling from index of refraction of 1.33 to medium with index of refraction of 1.5. i used the following…

I am building a raytracer in C for the school. Yesterday I successfully implemented my first recursive refraction, however I am not very satisfied with the result. a picture of my raytracer with 2 reflective spheres I find that the water ball…

I'm not a shader specialist, but I'd like to pass the color value to the shader that could maybe blended with the env map color. var shader = THREE.FresnelShader; // Thank you WestLangley for that trick var uniforms =…

I am writing a code to simulate the behaviour of a five-layer dielectric structure. The method used is the TMM methods.. Inputs are the incident angle on the structure. With this strcture, what I expected is a zero transmission after the critical…
