Tutorials written in the scripting language Python
All Python based tutorials can be found in <agxDir>/data/python/tutorials.
Most of the scripts can be started both with the native python and agxViewer.
To run these tutorials, AGX needs to be installed on the
computer. The .agxPy file suffix is associated to
the application agxViewer which will be executed for
the links below.
If you want to start one of the scripts manually in a command window, just write:
agxviewer tutorials\tutorial1_graphics.agxPy
agxViewer starts by default in paused mode. Remember to press 'e' to start simulation.
Press '1' to reload the scenes.
Tutorial: Granular bodies
This tutorial demonstrates how to create granular bodies within a container, setup a conveyor belt which transports the granular bodies. At the end of the belt, there is a shovel that will move the granular bodies left/right

Tutorial: Granular bodies and material
This tutorial demonstrates how to create and use GranularBodies, an efficient implementation of 6-DOF spheres. The granular contacts are simulated using a hertzian contact model with coulomb friction and rolling resistance.

Tutorial: Two-way interaction between Granular bodies and rigid bodies
This scene shows granular and RigidBody two-way interaction. A simple machine is driven by a granular flow. Some simulation parameters can be changed by the user during the simulation.

Tutorial: RigidBodyEmitter
This demonstrates how to use the agx.RigidBodyEmitter to spawn rigid bodies with any shape.

Tutorial: Using JSON files for data specification
This tutorial demonstrates how to create particle disitributions and set contact material parameters from extenal sources using Python's JSON library. By enabling the parallel Gauss Seidel solver the performance will scale well with the number of threads. You can change # threads with ALT+[number] Remember, using more threads than #hw cores will degrade performance.

Tutorial: Buffer access
This tutorial demonstrates how to access and manipulate the underlying data buffers for granular bodies and granular contact data via the BufferWrapper utility class that can create numpy arrays that maps directly to memory data in C++. We can then use this function to effecticley read/write particle and contact data without having to go through the high level Entity layer. This significantly increases performance when doing analysis on large amount of granular data in Python.

Tutorial: Granular contact data
This tutorial demonstrates how to access the contact data in the Python interface for granular bodies.

Tutorial: Granular field
This tutorial demonstrates how to create and visualize granular fields in python
