Sine Waves Visualized

Learn how to use sin and cos waves. I use unity here but, but the math is agnostic

Sine and Cosine are fundamental to game development. Once you understand how Mathf.Sin and Mathf.Cos work, you'll find yourself reaching for them all the time. You can create circles and waves, make things hover, create orbits, add enemy behavior, etc.

REUPLOADED: My original voiceover was horrible quality and quite cringe. I also wanted to fix the low bitrate.

Great work! I'd love to see an extended demonstration on different waveforms. Such as square, sawtooth, triangle, and manipulating them further to get very specific patterns. Introducing noise to randomize Y.
Anyway, great video! Love your content. Beautifully designed :)

Amazing short video! I just love your animations. Seriously, one of the most beautiful ones on youtube. :)

I would love to see a "how I made my visualisations" video.

Also, Quaternions

Very useful functions. Thanks for the visual presentation.

[Arda-bjku]

Very cool visualization! Gives me Freya Holmer vibes.

I've done the rippling array of objects before with wave functions for sure. I also like to apply a wave function to Quaternion.AngleAxis and have the objects pitch as if riding the surface of the waves.

My best use of sine/cosine is certainly for text. Using both their circle and wave attributes, I give the text a fake 3d effect, by rendering many layers of the same text above each other, slightly offset as well as a grow/shrink pulse. For a final effect I render the very front and very back layers in a different color, with the layers in between transitioning between the two. The final result gives a very believable 3d effect. Imagine it like some microsoft word headline word art, but it's animated and not afraid to show you all its sides over a certain timespan.

Very very helpful video, and background music too...🎉

[francescagreetham]

You’re so cool. This was amazing. Short, snappy and beautiful

[clavesi]

waveforms can be so simple but so useful, it's really amazing.

I wish someone show me this when I was in school learning this, it would have made a big difference!

[PixelBlight]

Such a great and beautiful example of how math can be so fun to play around with! 👏

Understanding the unit circle helped tremendously with school trigonometry, because our teacher only mentioned it like one time for some dumb reason haha.

This visualization is epic, thank you so much!!! Finally, 15 years after high school, the sin function makes sense to me! (teacher back then didn't do a particularly good job at explaining things...)

[theReimy]

This is top level production quality. Great work!

[michaelnawrocki]

That makes so much sense with the visuals. However, I would love to see a practical demonstration on like a coin or jewel for us to follow. Keep up the great work 👍

[dragovscar]

Are you kidding me i wasted like 1 hour to calculate bobbing and stuff and this gets recommended after all that work

[Skeffles]

Excellent visualisation of how they map to circles!

[manimuridi]

It would be awesome if you can make a guide on how you created these visualizations. Great content and I love these series! Thank you.

Wow lot of quality, you definitely deserve more subs.
