I watched 'The Drive Home' at shadertoy, and amazed by its simplicity(well, I find it's not now) and lifelikeness. thanks for shareing and your creativity!

[bjarkebech]

so so so so cool. thank you so much for taking the time to explain and share this. i've never had this much fun coding.

Thanks for sharing, but where can I find the explanation of CloestPoint emmm...

Very nice tutorial! Possibly you addressed this in a later video, but I think you ought to normalize the right and up vectors in your GetRay function. As you have it, your camera is looking horizontally, and all is well, but if you decide to look up or down your cross product with the global y axis will not be of unit length, and you will find yourself zooming in more than anticipated. It's looking really good though, I want to skip to section 6 to see your raindrops :-)

Hi, do I should to watch "How to create a camera" before starting with this tutorial?

[leunam]

Hi!This is amazing and Im so excited to learn!Im very new to shader and code and programming, is this based on C++ (Sorry silly question!)Thanks a lot!!!Amazing work!

Why using a 3D space for this effect ? Is this only for the raindrop effect at the end ? Couldn't it be achieved in 2D ?

[anassrazik]

thanks for the video, and i hope to do some sphere tracing and ray tracing techniques, and maybe some other camera setups (perspective, ortho, field of view) keep up :))

Isn't smoothstep undefined for edge1 < edge0?

wtf you turned into a ventriloquist at 15:06

What are the main differences between the camera setup here vs the simpler camera setup in an earlier tutorial?
