3D Rotation & Projection using Python / Pygame

Показать описание

This video was inspired by pythonista's 3D projection video. Link is included in the references section below.

In this tutorial I go over the math behind 3d projection/rotation and write code to display the projection of a rotated cube onto a pygame window.
If you followed the tutorial fully, thank you! You can also try creating your own 3-D points by making a new list of 3-d coordinates and iterating through those points instead of the points in cube_points! (ex. try a pyramid shape!)

Hi everyone,

Thank you all for the kind comments. I see all of them and appreciate every one. I never expected this video to reach so many people.
If I didnt' respond to your question, it unfortunately means I don't know the answer and I don't want to invest the time to figure out the answer - sorry.
Although the space is still very fascinating, Game development/math is no longer my main topic of interest since I started web development professionally.

I originally decided to make the 3D projection video because there weren't a lot of videos on YouTube explaining both the math and the code behind it.
Although I'd be happy to upload videos on web development, there is already so much content out there that it feels redundant.

That said, I'm pretty curious about your guys' main topic of interest so it would help a lot if you could leave a comment here on what kind of content you'd like to see, if any.
Depending on whether my knowledge/interest and your guys' interests align or not, I'll try coming up with another video idea for the future.

Thank you all again

yutaa.

just what I was looking for. Very clear explanation. This guy deserves more recognition

The Time I spent trying to find a video like this that explains the maths behind it!

EDIT:
You need more subs this is AMASING

Very clear. Next step how to fill the polygons of the cube with a solid color or texture please

Oh wow, what a journey! I really enjoyed this video! Thanks for helping me understand how pygame generates 3D objects!

genuinely one of the best tutorials ever
thanks!

Great video! Just one correction for the newcomers: remove the key detection from the event loop and put it inside the main loop, so it doesn't depend on the amount of events coming in.

Good tutorial! Thanks! I was playing around with PyGame a little today, and I was wondering how to do something like this. I was already familiar with rotation matrices and matrix calculation in general, but wasn't sure how to actually code it in Python. This helped a lot!
You, sir, have got yourself a subscriber!

Iv watched so many videos and this is the first one that I actually understood about 3d. Thank you seriously

Finally understood matrices after this thank you

This is amazing video with great explanation math behind it, which is really important to understand. Thank you

I havent tested your code but its calculated in the same way as many other python tutorials which cover up a fatal flaw by using a cube. The issue is that in certain conditions the polarity of the value of the z axis flips in all points which is invisible on a cube
