How do polygonal models work? | Computer Graphics Essentials

In this video, I explain one of the most important concepts in computer graphics - polygonal models.

This is so well-explained and demonstrated that it feels illegal to watch for free. Thank you Vojtech :)

[JohnR]

This is gonna blow up, thank you so much for creating this!

Happiness is watching a youtube channel growing from the beginning!
All the best❤

This is amazing! I'm shocked your channel isn't bigger, so underrated

triangles are always used by GPU to render the object to the screen, but in 3d modeling triangles are not good, you can't loop easily, select a poly ring, do proper edge flow etc. so in modeling people are using quads and simply avoiding edge cases where quads might break, which is not that often tbh, quads are only breaking when a 3d modeler is a beginner and he/she can't produce quad only mesh.

Vertices edges and faces are not the most simple representation.

The edges are redundant.

Faces can be represents as triplets of vertices. No need for edges.

10:30 confusing wording, correct wording should be - a vector perpendicular to the face of a polygon.
