Simplifying meshes, Managed Dx C# help
Author
Hi, i am working my way through Managed Direct x 9 kickstart by tom miller and there are some differences in the code. I can correct most of them myself but i am having a problem simplifying meshes.
i am using the latest direct x and .net
pg 125. this is what i have atm.
it gives me an exception.
An unhandled exception of type 'System.NullReferenceException' occurred in microsoft.directx.direct3dx.dll
Additional information: Object reference not set to an instance of an object.
the problem is in trying to simplify and not the loading, the last method throws the exception.
any help would be much appreciated. Thank you

It looks like mesh != null, check that adj != null and maybe the argument where you put null should not be null.
Hope this helps

Not entirely sure on this one, but I believe that on this line:
Mesh tempMesh = Mesh.Clean(CleanType.Simplification,mesh,adj,adj);
if the cleaning fails, it returns the same mesh, and probably the "adjacencyOut" which is your adj graphicsstream get filled with a null value, cause the cleaning failed.
that's just my guess by looking at the directx docs
Mesh tempMesh = Mesh.Clean(CleanType.Simplification,mesh,adj,adj);
if the cleaning fails, it returns the same mesh, and probably the "adjacencyOut" which is your adj graphicsstream get filled with a null value, cause the cleaning failed.

This is thread starter, rivierakid
in the text book the overload is
Mesh.Clean(mesh,adj,adj);
but it seams the last updates have changed the overload
so i wasnt really sure what to do instead.
why would the clean fail?

Once, Clean for me found some 'bowie' vertex ordering or sharing or something that it couldn't fix.
Don't dispose the mesh...just assign the mesh like :
mesh = tempMesh;
There seems to be a problem with the disposing of the original mesh also disposing the tempMesh (although they are not the same reference).
It's not really a memory leak since the GC will eventually get to it.
