I've no clue what you're doing but i like your accent. Couldn't tell you're indian if I wouldn't have seen your comment. Good luck with your videos tho :D

Very nice video. You are a godsend for a beginner like me.

I have a question about your codestyle.
Is there a reason that (eg. on line 63 of this program) you used a float in a loop rather than an integer?
In CPU programming usually integers are used. I am also worried that floating point errors might cause you to miss or gain a loop depending on the number of repetitions.

Secondly, you frequently use expressions in the style of `x = x + n` rather than `x += n`. Is this just your preferred style, is it for beginner friendliness or is there a deeper reason?

great video. Can you make a video on tangent space normals with noise? And is there an optimized way to calculate the normals that doesn't entail having to call the noise function 4 times?

is there a way to add a domain warp strength value, if so how?
