[osg-users] ViewDependentShadowMap improvements

[Daniel Schmid]

Hi Wang

 

In your latest submission update, there is the possibility to set splitvalues. I somehow have a hard time to figure out how to use it.

In my settings I calculate shadows up to 500 m max distance, with two shadows for my sun-light. Can’t I just say that I want a shadowmap going from 0..100m and the second one covering the rest up to 500m?

How do I have to set the splitvalues to achieve this?

With the different shadow maps I expect the scene to be culled in each shadow pass according to the split distance said. This means for me that I my first split is pretty close to the viewer I have my first shadow map working at a high resolution for close objects. The further I move the split value, the more triangles are taken into that specific shadow pass…

 

Hope you can explain it in some more detail…

 

Regards

Daniel
