It won't work on bitmapped graphics like Photoshop documents. You need vector graphics like Illustrator documents. And just putting the psd into Illustrator won't work: you need real vectors.
Now, you could engage in a bit of trickery by using the photoshop document for the face, and the edge of the graphic (filled in) built in Illustrator for the extrusion.
Expect very long render times. Ray tracing is a bear, and that's no joke.
However, in MY program the geometry options that come up are Curvature and Segments.
That's perfectly normal for a raster image. Only shape layers may be extruded or Vector layers without raster effects that are converted to shape layers, and text layers may be extruded.
