POWhat looks to be wrong with this DirectX renderred model where you can only see the inside walls but the outer ones are transparent?
 

Note that there are some explanatory texts on larger screens.

    <p>This has been surprisingly difficult to diagnose for whatever reason, but I figure someone here will be able to tell what's wrong really quickly.</p> <p>To me, it looks like the polygons are being drawn with counterclockwise winding when they should have clockwise winding, that is, they are facing inwards and not outwards. I'm wondering if there's another way (other than creating redundant polygons) to make directx fill polygons on both sides (front and back).</p> <p>Here are multiple screenshots of the rendered model (it's an elk toy):</p> <p><img src="https://i.stack.imgur.com/pyoLI.png" alt="enter image description here"></p> <p><img src="https://i.stack.imgur.com/7JQkB.png" alt="enter image description here"></p> <p><img src="https://i.stack.imgur.com/oQ3IL.png" alt="enter image description here"></p> <p><img src="https://i.stack.imgur.com/Qj9u5.png" alt="enter image description here"></p> <p>For comparison, another model renders correctly and looks like this:</p> <p><img src="https://i.stack.imgur.com/qetoc.png" alt="enter image description here"></p> <p>Thank you for taking a look</p>

    1. COIt almost looks to me like you don't have depth testing working properly. It looks like parts of the model that should be behind others, aren't. Can you provide screenshots from other angles? Without knowing how it's meant to look it's tricky to tell what's up.

    2. COYes I can, I had that thought too, but I don't know much about DirectX's Z-buffering. I'll provide more screenshots. One moment. EDIT: Done

    3. COSince it looks like it's a winding issue, why can't you just reverse the winding?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
