If you want to contribute to Babylon.js (What an _excellent_ idea!), you should try to align your code with the following naming conventions:

- Private variables are named starting with \_ : `_myVariable`
- Camel case is used for non-static properties/functions/variables: `var myUberUsefulVariable`
- Pascal case must be used for static functions: `BABYLON.Vector3.Project`
- Braces \{\} must be used for every block, even when there is only one line:

```
if (condition) {
    this.doSomething();
}
```

- Braces start on the same line and end on the next one
- Each new file must contain only one class
