Raymarched Reflections

In this video we'll go over how to do proper raymarched reflections.

funny story; I been building robots n stuff; so someone who wanted to get into coding messaged me about how to start; and they shared me one of your videos and I laughed my guts out. This is no intro to coding channel lol.

:O I didn't know the reflect() function existed until now! Up until watching this video I was just doing it like this:
ray = normalize(ray-normal*vec3(2.)*dot(normal, ray));
Yay thanks for teaching me this!

It's really nice, that you're so straight to the point, and go a little bit down the roads, that intuitively would work (such as recursion), and then backstep and implement it the way, that's possible. Superb. Again.

You make real quality tutorials for shaders. Awesome work!!

[DeanEdis]

Thanks very much! Clear and useful, as ever!

Really good video as always!:) Would be really intresting to see a video about this principle with lower optimised reflections as the iteration goes up! or shader rendering optimisation tricks in general;)

[danb]

will you do a video about refractions too?

[Igor_Zdrowowicz]

now its time for multiple bounces using raymarching :D

[DB]

hey anyway you can cover emissive materials? been trying to make emissive materials for a few weeks now sadly most examples are for pathtracers on shader toy

[MrlegendOr]

Is raymarching better than other techniques for reflection/Shadow/GI?

[Bleenderhead]

shouldn't you displace the new ray origin along the reflected direction, not the normal?

This guy is a little green behind the ears!

@27:20 why do you write clamp(1-dot) and not 1-clamp(dot)?
