AOI scene projection
====================

An [AOI3DScene](../../../argaze/#argaze.AreaOfInterest.AOI3DScene) can be rotated and translated according to a pose estimation before to project it onto camera frame as an [AOI2DScene](../../../argaze/#argaze.AreaOfInterest.AOI2DScene).

![AOI projection](../../img/aoi_projection.png)

``` python
...

# Assuming pose estimation is done (tvec and rmat)

# Project AOI 3D scene according pose estimation and optic parameters
aoi2D_scene = aoi3D_scene.project(tvec, rmat, optic_parameters.K)

# Draw AOI 2D scene
aoi2D_scene.draw(frame)
```
