Aliens (Scanner scene)

GLSL Shadertoy Shader

Another Aliens-themed shader, motivated by me watching this clip from the movie.

I try to add add something new each time I make a shader, and this time it was the ‘frost’ effect on the cryo pod and the noise in the ‘laser’.

The reflective helmet glass and laser effect were calculated using ray-sphere ray-plane intersections, allowing me to keep the ray-marching loop simple and fast.

The GLSL shader source can be found here.
