Coordinate System
The point cloud is rendered in a right-handed coordinate system (see OpenGL description).
Bounding Boxes
The bounding box is internally represented with a centroid, three dimensions and absolute rotations in Euler angles. Rotations are counter-clockwise and inside 0° and 360°. The initial bounding box is oriented with the x-axis representing the length of the object. The bounding box vertices are ordered clockwise from bottom to top starting at the origin. The sequence is adopted from the bbox library.
| Point | Position (x, y, z) |
|---|---|
| 0 | left back bottom |
| 1 | left front bottom |
| 2 | right front bottom |
| 3 | right back bottom |
| 4 | left back top |
| 5 | left front top |
| 6 | right front top |
| 7 | right back top |
If the vertices label format is selected, the points will get exported in a list in this sequence.
When labelCloud shows the orientation, the arrow points at the right side of the bounding box (2, 3, 6, 7) and upwards (6, 7).
