 # Content:

This dataset contains a test scene created and rendered with Blender [1] and the addon script [2] extended for Blender 2.8. We provide the Blender file and the rendered scene.

The scene contains a mirror reflective torus rendered in a regular camera array of 21x21 cameras.

In addition to the 3D model, we provide the images in the folder `parallel_cameras` : resolution of 2000x2000, the cameras are parallel, with a principal point at the center of the image.

The dataset contains:
 - a `camera.json` file in OMAF coordinates system (Camera position: X: forwards, Y:left, Z: up, Rotation: yaw, pitch, roll) [3],
 - a `parameters.cfg` generated with [2],
 - a `texture` folder containing the rendered views in png format,
 - a `depth` folder containing the associated depth maps in exr format.
