Hi,
I've been toying around with the samples from the AdrenoSDK and I'm curious as to know how the shadow volume extrusion can be realised purely in a vertex shader without the CPU. My main question is about the prepared meshes with the "Edges" prefix, is there a special tool which is used to make these mesh edges? I don't quite understand this part.
Thanks!
Hi Alex, the challenge with using shadow volumes is that you need a way to generate the edge meshes, and the tool used for the Adreno SDK samples is not available. It is recommended that you use a different method, and both Projective Shadows and Shadow Maps are samples available in the Adreno SDK that you can take a look at.
