Update: Added option to allow viewing model using a cross eyed method, as well as the original "wall eyed" method.
This program renders two images of a simple model from separate camera positions. When viewed similar to a Stereogram image it produces a TRUE 3 Dimensional view of an object. No special viewing devices are needed to view in full 3D. (See the help file for how to view it properly.)
This example uses custom D3DTLVertex (Transformed and Lit Vertices) for rendering. The program is responsible for the transforming and lighting of the 3D scene and only sends the screen coordinates, rhw, and color of each vertex to D3D for rendering.
This program implements most functions needed for 3D rendering in SOFTWARE including:
3D Object Rotation using 3X3 Matrix Transformation
Surface Normals
Backface Culling
3D Projection to 2D screen
Z Sorting
Dynamic Lighting (Flat Shading and Gouraud Shading.)

All I can say is WOW!
One interesting thing...
When I look at the sphere (globe), I
see it 'concave', whereas my wife sees
it as normal ... must be a right-brain
left-brain thing?
5 stars on this one!

Thanks for the positive feedback. You are probably right about the left/right brain thing (in a way.) What is really happening is that you are looking at it cross eyed as if the image was in front of the monitor. However, the program is setup to be viewed as if the image was inside, or beyond the screen (wall eyed.)
After doing a little research I am starting to realize many more people view stereoscopic images cross eyed than I originally thought. Personally, I am not able to view them cross eyed no matter how hard I try.
I will be making an update very soon (probably tonight) that adds the ability to swap the images to allow for cross eyed viewing as well.
Again, thanks for the feedback.

Great code.
How can I import WRL(VRML2.0) files to this program from Photo Modeler Lite ?

I have DirectX8 but get Automation error. Any idea what this might be?

My Automation error was caused by not having the Graphics Performance set to maximum. I usually have it down a notch or two because not all VB graphics will work at maximum!!

Robert, I sent you an e-mail requesting a little more info. Thanks for reporting the error.
mwcStudio, I only intended to use custom models so I could have more control over the rendering. I have however checked out some .wrl files
and think I may be able to write a conversion program. There will be quite a few limitations though. I'll post again after I take a better look at it.

Where can I download DX8? I can't find a download on msdn.microsoft.com. If possible, could someone just send me the library (DX8VB.dll or something)?

Great Demo, reminds me of a 3d demo we used in mech eng which utilized the red/green lines...images stand off a flat surface, you reach for and think you can touch them. As in 3d photography where two images are taken at different angles similar to the space between our eyes thus crossing of the eyes is necessary to see the image in true 3d visual. Again, good demo and I will try to write someting that displasy the version I mentioned. keep up the good work.

Exellent!!
But I don't know how do you make *.def files..
Whether Exporting Vertex Data from CAD / 3D Max or other tools...
Please Help.. Show me a course of Convert 3d-files into [*.def file]
send me your sample or data or method.....if you send that...i will very very thanks.. ^^

I just stumbled across this code while searching for "gouraud" and I have to say this is quite possibly the most incredible visual feast VB has ever given me. It's like VB meets iMax. I must've played with the BoxFrame object, eyes crossed, while staring at the screen for about an hour. Utterly mesmerising. (*)(*)(*)(*)(*)
