In this 2013 GDC talk, Intel’s Stan Melax shares some useful tools for programmers to help render avatars that can interact with 3D Geometry in games.

GDC talks cover a range of developmental topics including game design, programming, audio, visual arts, business management, production, online games, and much more. We post a fresh GDC video every weekday. Subscribe to the channel to stay on top of regular updates, and check out GDC Vault for thousands of more in-depth talks from our archives.

I am a web application Developer(Java) and I realise how dumb I am compared to these guys. All we web developer do is learn frameworks, use API's built by people smarter than us and do CRUD operations with a Database.

I think we should stop calling ourselves developers, its an insult to real developers. 🙁

Excellent talk it's been always a mystery to me how physics engines work, and this talk provided great insight! Would definitely buy a book written by this guy. Thanks sir <3

I have talked a lot with ppl on reddit 3d graphics subreddit and many

others about if it would be possible to do today what Carmack did in the

90's in term of 3d engine development etc and trying to build a engine

who would/could rival Unreal 5 etc the consensus I received was that

it's impossible to build a large engine alone theses days because they

are 100x more complex than in the 90's and there is over 100 dev working

on Unreal all time .. but it would be possible for a 3d graphics

programmer to build a small 3d room like a 3d shooter to show all the

examples he learned kinda like a portfolio if you want… mirror,

reflection, water, light etc etc

I wanted what's your opinion

about all this and if it's a waste of time to learn 3d graphics theses

days if the industry as a whole is standardizing on Unreal…

Thank you for your time

Does anyone have the presentation slides from this?

my college math class?

To get the normal and the area of a triangle without picking an odd man out, use `Area = 1/2* |a×b+b×c+c×a|` and ` n = unit(a×b+b×c+c×a)`.

30:16, I'll try to finish the course!

Sololearn?

fantastic talk, theme and speaker. Thanks for the upload, it was very insightful!

I believe a third of what he said aren't even used in 99.9% of 3D Computer graphics. Examples: nobody calculates outer product. Moment of inertia very rarely. Tetrahedron covariance?? Inertia tensor??? Jacobian??

A good in depth talk, although self-indulgent level of complication was introduced.

Thank you for this awesome overview, I learned a lot, but please, Runge is pronounced somewhat like Roongeh, my ears ^_^.

Oh, cool! I've had that numerical drift problem happen to me without realizing the name for it! I was implementing some orbiting bodies, and at first I did it by setting their velocity normal to the vector between their position and the origin, but they (as the name implies) slowly drifted away. I didn't even realize it until I walked away from my computer while it was running, and came back and saw their orbits had dramatically grown, haha.

1:14 Yep, if a math illiterate like John Carmack can succeed then basic school math should suffice.

Oh Stan you bantersaurus!

Fantastic Lecture. It's nice to see just how many different ways relatively basic Trig and Linear Algebra can be used to solve these kinds of problems. It really encourages you to think outside the box of your preconceived notions of how math is supposed to be applied to 3D game geometry and showcases how rewarding some lateral problem solving skills can be.

Every day I discover a new way in which all the math I picked up in college is inexhaustibly useful.

2:20 HELP! I'm already lost!

Nice, got to dig into the implicit Euler stuff.

I guessed he was a professional body builder but i think i was wrong

Hey that's the guy that programmed MDK! He's got another talk about how they did collision in that game.

Lost me 15 minutes in. Shows what I know. Time to brush up it seems.

thakns for this overview. it is exactly the list of referencable topcis i am looking for right know. perfect timing.

hey, im programmer and 3d student, this will fill well.

I've been developing 3D games for 2 years and Modding for longer, I've run into problems with the Geometry of shapes before sure, but this just seems way to complicated. Why not use the hundreds of tools available to do this for you? I've spent hundreds on tools to assist with shading, physics, and scripting. I've never heard of this in my life. What modern game dev has to do this from scratch anymore? This just seems like a huge waste of time.
