3D Graphics: Crash Course Computer Science #27

Today we’re going to discuss how 3D graphics are created and then rendered for a 2D screen. From polygon count and meshes, to lighting and texturing, there are a lot of considerations in building the 3D objects we see in our movies and video games, but then displaying these 3D objects of a 2D surface adds an additional number of challenges. So we’ll talk about some of the reasons you see occasional glitches in your video games as well as the reason a dedicated graphics processing unit, or GPU, was needed to meet the increasing demand for more and more complex graphics.

Pre-order our limited edition Crash Course: Computer Science Floppy Disk Coasters here!

Best explanation of Anti-Aliasing ever.

The study of 20 years converted into 12 minutes

"Triangles for the win!, " is a phrase I never expected to hear in my lifetime. Great episode. Thanks for sharing!

[ihcho]

Most fundamental 3D modeling techniques are explained just in 12 minutes in crystal clear way. Wow! I'm so much impressed.

"We live in a 3D world and I am a 3D girl." Said so seriously I almost didn't catch, amazing.

An enormous amount of computing. I just completed a clip that runs 1 minute, 21 seconds (Blender 2.8). It took 2 1/2 days to render.
This video explains why. Great work.

Carrie Ann, please make this series go forever

[typograf]

I'm impressed on how you can present a rather complicated subject so that people get a good idea about what is going on. I presume.

[vietquoc]

great respect! finally I got an overview of all the terms used in GPU in a very well explained manner. LESS is MORE, SIMPLICITY is a KEY... Please keep going the good work!

I'm not sure where to put this comment, but I've been super impressed by this whole series! The topics are pretty textbook, but they are presented very well: great graphics, inflective speaking (without it sounding intentional or patronizing), historical context, and in my opinion this is in comparison to the other crash courses y'all have done as well. (sorry to the other crash courses =P ) Anyhoo, good on you! Can't wait for more! =D

[Hambonillo]

Very cool. The humor/speed/content ratio is perfect, and I loved the audio effects.

[SilverAura]

Man, this episode is actually incredibly well done. I mean all of these are, but the way you guys simplified this was especially well done.

[mayank]

Great way of introducing an amazing technique like back face culling as "speaking of glitches".

[TheTomexification]

Thank you PBS and everyone that finances it, this is a great show.

[Danielevans]

This series is no lie, ONE OF THE BEST PARTS of my week

[markanderson]

thank you for this series, its super helpful to have someone easily lay out everything from the bare metal architecfture the way up to high level programming languages and various technological applications

[expansivegymnast]

Just wanna say this series is amazing and keeps on giving. This is a great first introduction to all of these topics.

[micafe]

This video was very helpful. I've just started learning 3D graphics and this helped me understand how it works. Thanks!!

[Jony]

Very well made video with nice simple explanations while also mentioning the more complex ones, good job

[lobachevscki]

As a mathematician specialized in computer graphics, thanks for this.
