Course: Pixar in a Box>Unit 15

Lesson 1: Rendering 101

Start here!

Welcome to Rendering!

Welcome to Rendering!

In this topic we are going to explore how pixels are painted by solving systems of linear equations.

This topic contains two lessons:

Lesson 1: Rendering 101

• Appropriate for all grades 5+

Lesson 2: Mathematics of Rendering

• Appropriate for the senior high school level
• Discover the equations used at Pixar to calculate intersection points in three dimensions

• Just about how long does it take to create a full movie like that?
• It takes Pixar anywhere between four and seven years to make a movie.

• This is a great effort by Pixar to spread education about the industry. The content is helpful to even those already working in the industry. My question, being a Lighting artist is that does Pixar consider employing people who do not possess educational qualification on paper, but have gained knowledge say via Khan Academy or other experiences?
• In simple terms, what is rendering?
• Rendering is the process of making an image. You start with a 3D model of the scene, characters and lights as code in the computer. Rendering takes those elements and "draw" the image of how they would appear on the camera.
• I have a good question, becuase I'm doing animation for the first time, within my own curiosity I would like to know if "Is it always necessary within having to ("RENDER") an animation in order for it to act as real as seen in movies and short films? If so then I would like to know more about it. Thanks.
• Am I the only one having issues with the interactives for this lesson? The Ray Tracing interactive hangs in an infinite loop. The Matching Properties of Lighting also seems to not be working correctly. I have submitted an error report, directly, but since this has been an issue for several weeks, I'm beginning to wonder if it's me.
• How long does it take to position the camera for the epic scenes?
• Mostly definitely from 15 minutes to an hour if you are deadset to capture that epic scene

• How long did it take to make the incredibles?
• The Incredibles 2 Took 14 Years To Finish.
I don't have a very good answer but Producer John Walker simply told GameSpot that "We all had other movies to make and other things to do, and also life goes faster than you think."
I hopes this helps!😊
• I'm a graphic designer, and I was wondering, how do they manage to render so quickly?
• I'm in a science research class and I am looking to do something in the field of computer graphics and animation. I asked my teacher about it and she was confused as to what kind of research I would do. Do you have any ideas?

• I assume you don't need original research (something that's never been invented before). Off the top of my head:
Image filtering and anti-aliasing.
Uses of imaging other than making pictures of visible light. This could touch on X-Rays, digital elevation maps, thermal imaging, heat maps, etc.
The Bi-Directional Reflectance Function—a mathematical approximation of how light interacts with a surface.
Techniques of Global Illumination.
High Dynamic Range imagery (HDRi).
The physics of color: Additive and subtractive colors and their relationship to one another.
Simulation and dynamics engines: Modeling physical systems in a virtual environment. Fire, smoke, falling and colliding objects, and so on.

There are topics in that list for any level of complexity from middle school to college undergraduate, and several have adjustable levels of scope that could occupy a two-week research project up to a full semester, or even longer.
