I could not reproduce the issue. Did you modify the example with a new combo box?

Edit: Are you running Windows 10?

vedamsudhakar commented 8 years ago

Actually I am getting index Out of range exception with Quads as default option. So I changed to Triangles as a default Mesh Topology. @smischke: Yes I am running in Windows 10.

@objorke : Also PRECOMPILED_SHADERS is removed from conditional compilation symbols ( HelixToolkit.Wpf.SharpDX project). I thinking that tessellation effect is not properly compiling. please help me.

Hi Stefan Mischke,

I am aware of those kind of exceptions. but this time it is not giving any exceptions just model rendering is missed. In this rotating mouse wheel to zoom in and zoom out , camera info also is updating. Please help I need tessellation sample to run.

Please try one of the issues in the example browser. It has a better error reporting. [image: hxsdxexception] https://cloud.githubusercontent.com/assets/8622962/11532518/970442e8-9904-11e5-9175-8238a3a19089.png

Have you installed the DirectX Runtime?

@objorke : can you please send your running tessellation sample

vedamsudhakar commented 8 years ago

Hi I found the rendering problem. :) in my code following line is problem. if (geometry == null) in Attach(IRenderHost host) in PNPatchGeometryModel3D class it should be if(geometry!=null)

Thanks
