Re: What am I doing wrong ?

Hi,

I have created a mesh class in visual studio 6.0 c++.

I can create a device, render objects and can edit the objects by for
instancnce selecting a cluster of vertices and processing the vertices
and can do this multiple times on a sinlge vertex cluster.

The problem I have been encoutering is that, if I select a second
vertex cluster and try to edit that , the program crashes.

I have re-written the application from passing pointers to the mesh
object to functions to an application that passes references but I
still get the same type of problem.

in my current version, I declare a reference, m_ref and then pass
this object to the following sequence of function calls :

create sphere ( my_mesh& p_mesh ) returning p_mesh.

select_vertex_cluster ( my_mesh& p_mesh ) returning p_mesh.

Edit_vertex_cluster (( my_mesh& p_mesh ) returning p_mesh.)

If I call the Edit_vertex_cluster , for a second time, it just cannot
find any data, that has been created previously within the object.

I am loosing quite a lot of hair with this one and I have inplimented
a copy constructor but , really I am so confused right now that I just
have no idea what I should be doing .

Can anyone see what type of thing I may be doing wrong here?

I really would appriciate some help with this.

Thanks in advance,
