[Interest] Understanding issues with Qt3D shadowmap example

[Volker Enderlein]

Hi,


I'm currently playing with the shadowmap example of Qt3D. When having a 
PlaneMesh at (0, -5, 0), a CuboidMesh (width=height=depth=1) above the 
PlaneMesh at (0, -4, 0), and a directional light source at (0, 30, 0) no 
shadow is visible on the plane. Because the CuboidMesh is above the 
plane I would expect a shadow to be cast on the PlaneMesh. Adding a 
small change in position of the light say (0.001, 30, 0) procduces a 
shadow on the PlaneMesh.

Do I miss something important?


Cheers Volker
