Ten Minute Physics

This is the page accompanying my youtube channel Ten Minute Phyics.
In short episodes of about ten minutes I explain the basic concepts
of physically based simulation. Each time I write a little javascript
demo that runs in any browswer.

Write a cool standalone html demo based on one of the tutorials. Send
me the html file, your name, country, short description and a
thumbnail (640 x 360) to matthimf at gmail dot com. If you like you
can also send me a link to your personal page. I will then put your
contribution online here.

     17 How to write an Eulerian Fluid Simulator with 200 lines of
     code.
[17] In this tutorial I explain the basics of Eulerian, grid-based
     fluid simulation and show how to write a simulation engine based
     on these discussed concepts.

     16 Simulation on the GPU
     In this tutorial I give a short introduction to simulating on
[16] the GPU. I use python in connection with the nvidia python
     extension warp as a simple way to write GPU simulations.

     15 Self-collisions, solving the hardest problem in animation
     In this tutorial I give you 5 tricks for stably handling cloth
[15] self-collisions. We use the cloth simulation of tutorial 14 and
     the hash grid introduced in tutorial 11.
     Video Code Demo Notes (PDF)
     14 The secret of cloth simulation
     In this tutorial I reveal the secret of cloth simulation. I use
[14] it to write a very fast and stable cloth demo that simulates
     6400 triangles at more than 30 fps on a cell phone in
     javascript.

     13 Writing a Tetrahedralizer for Blender
     In this tutorial I explain how to create a tetrahedral mesh for
[13] a surface mesh using the incremental Delaunay method. I also
     briefly discuss the implementation as a python blender plugin.

     12 100x speedup for soft body simulations
     In this tutorial I show how to speedup soft body simulation by
[12] 100x by embedding a high detail visual mesh into a low
     resolution tetrahedral simulation mesh.

     11 Finding overlaps among thousands of objects blazing fast
     In this tutorial I show how to find overlaps among thousands of
[11] objects using spatial hashing. In addition to explaining the
     method, I also show how to implement it in a very efficient way.
     Video Code Demo Notes (PDF)
     10 Simple and unbreakable simulation of soft bodies
     In this tutorial I show how to simulate soft bodies with in an
     unconditionally stable and simple way. Using a discrete rather
[10] than a continuous model and a local instead of a global solver
     removes almost all difficulties of traditional methods and
     yields a simple, short and fast algorithm. I recommend to watch
     tutorial 9 first.

     09 Getting ready to simulate the world with XPBD
     In this tutorial I introduce general extended position based
     dynamics or XPBD, a simple and unbreakable method to simulate
[09] almost everything. The tutorial is self contained. However, I
     highly recommend to watch tutorial 7 first to refresh your 3d
     math.

     08 Providing user interaction with a 3d scene
     In this tutorial I show how to enable the user to pick up move
[08] and throw objects in a 3d scene. For this I introduce the
     concepts of a mouse ray and ray casting.
     Video Code Demo
     07 Intuitive 3d Vector Math for Simulation
     I give an introduction to 3d vector math, the math that we need
     to write 3d simulations. In the compact presentation I focus on
[07] the part used in simulations. In addition to the definitions of
     the concepts, I explain my personal intuitions behind the
     concepts which I developed over time.

     06 Writing a triple pendulum simulation is simple
     I show you how to handle hard distance constraints with Position
     based dynamics. They can be used to simulate a large variety of
[06] objects like cloth, ropes, hair, fur, sand and many more. To
     demonstrate the accuracy of PBD we will write a triple pendulum
     simulation.

     05 The simplest possible physics simulation method
     I introduce the Position Based Dynamics method to simulate
[05] constraints. I apply it to the circle on wire problem and
     compare it to the analytic solution to demonstrate its accuracy.

     04 How to write a pinball simulation
     I show you how to handle ball - capsule collisions and
[04] collisions against arbitrary boundaries represented by segments.
     I also show how to handle touch and mouse events.

     03 - Ball collision handling in 2d
[03] I show how to handle collisions of balls in 2d while creating a
     billiard scene.

     02 - Introduction to 3d and VR web browser physics
[02] We make our cannonball 3d and turn it into a VR demo using the
     graphics engine THREE.js.

     01 - Introduction to 2d web browser physics
[01] I give a brief intoduction to this channel and to physics. After
     that we write a 2d cannonball simulation.
