This directory contains select snippets adapted from the ones included with PhysX SDK.
Generally speaking little has been done to make these C#-like, instead preferring to have them closely match the original snippets to make it easier to compare and contrast between the C++ and C# versions.
Note that since much of this code is basically copied straight from the PhysX SDK, it falls under a different license than the rest of this repository. See the notice at the top of relevant files for details.
First make sure you have built and generated bindings as described in the main project readme. Once that's done you can build and start the samples using dotnet or from Visual Studio.
Each snippet has a description of what it does at the top of their main file. Most snippets render an output, but a handful do not for one reason or another.
All snippets with a visual output can be navigated by pressing the WASD keys and clicking+dragging the mouse on the window. A handful of the snippets have additional controls, see below.
The following preprocessor conditionals can be toggled at the top of the snippet:
| Conditional | Description |
|---|---|
USE_REDUCED_COORDINATE_ARTICULATION |
Disabling this will use PxArticulation instead of PxArticulationReducedCoordinate. |
CREATE_SCISSOR_LIFT |
Disabling this will activate a differnet simulation involving a ball tied to a rope. Enabling requires USE_REDUCED_COORDINATE_ARTICULATION. |
This snippet does not have a renderer. It demonstrates an optimization technique for actors with thousands of shapes. The overly simplistic renderer used for the snippets doesn't support this and fails with an assert.
You can view this sample using PVD, although it is not particularly interesting to look at.
Additional controls:
- B will create an additional stack of boxes
- [Space] will shoot a ball
Additional controls:
- [Space] will shoot a ball
You can toggle gUseBinarySerialization in the main file to choose between XML and binary serialization.
You can use USE_FILES in Program.cs to toggle between serializing the objects to memory or files. (This is specific to the Mochi variant of the snippet.)
This snippet can be configured by toggling OVERLAP_COLLISION_AND_RENDER_WITH_NO_LAG and OVERLAP_COLLISION_AND_RENDER_WITH_ONE_FRAME_LAG in the main snippet file. See the snippet's description for details.
Additional controls:
- F1 - F9 will select between different variants of the snippet.
Toggle BLOCKING_SWEEPS in the main file to change how wheel scene queries are performed.
Toggle the index used to initialized gLengthScale between eLengthScaleInches and eLengthScaleCentimeters to use two different vehicle scales.
