IModelJson.AxesProps Interface
- There are multiple ways to specify an orientation
- A "Best" among these is application specific.
- An object with AxesProps should only specify one of the variants.
- YawPitchRollAngles uses 3 angles.
- Cases where only one of the 3 is nonzero are intuitive
- Cases where more than one is nonzero have difficult interactions and order issues.
- xyVectors uses a vector along the x direction and a vector into positive xy plane along any direction not parallel to x.
- In most cases, users supply a normalized x and the actual normalized y vector.
- zxVectors uses a z vector and another vector into the positive zx plane.
- In most cases, users supply a normalized z and the actual normalized x vector.
Properties
| Name | Type | Description | |
