[Dev-C++] Direct 3D help please!

[Daniel G. <sp...@ho...>]

<html><div style='background-color:'><DIV>
<P>Here is the problem - I'm using the tutorial here ( <A href="http://www.wksoftware.com/publications/d3dim.html">http://www.wksoftware.com/publications/d3dim.html</A>&nbsp;) to create a 3D triangle that spins. The problem I have is this... I am getting errors that tell me that "struct IDirect3D has no member named lpVtbl". I am 100% sure this is because in C++ you pass a REFERENCE to a GUID to IDirectDraw::QueryInterface. For example:</P>
<P>C code:</P><PRE>// pass address of IID_IDirect3D to QueryInterface
lpDD-&gt;lpVtbl-&gt;QueryInterface( lpDD, &amp;IID_IDirect3D, ( LPVOID * ) &amp;lpD3D );
</PRE>
<P>Whereas in C++ you must have code like this: <PRE>// pass reference to IID_IDirect3D
lpDD-&gt;QueryInterface( IID_IDirect3D, ( LPVOID * ) &amp;lpD3D ) ;
</PRE>
<P>Below are the troublemakers - HOW DO I FIX THEM?</P>
<P>&nbsp;</P>
<P>Failing that has anybody wrote a tutorial about putting 3D images on screen in C++ that works on Dev-C++ ?</P>
