Wireframe Quads, not Tri's?
Author
Just briefly, is it possible to get DX to draw wire-frame, but instruct it to skip drawing a particular part of the tri? I have a wireframe toggle in my map editor, and all the diagonal lines make things a little confusing. I suppose I could use a line-list but... that''s a lot more work than just FillMode=WireFrame.
If you want to render wireframe quads, your models must be composed of quads. Then you can have two custom calls. The one to draw regular quads would try triangles while the line one would generate a line list.

No...there is a thing you can set so it renders everything with lines. I''m not sure what it is though.

Right. It''s SetRenderState(D3DRS_FILLMODE, D3DFILL_WIREFRAME). But because Direct3D does not have native support for quads, rendering quads would turn out to be rendering two tris, which would have the diagonal.

You could use a texture that''s basically just a box. Then when you render normally it will look like "wireframes" of quads.

Uhhhhh! Thanks AP. Dunno how I missed that one. Just have to render it twice... once with the normal texture and then once with the quad texture. Doesn''t help so much with the meshes, but it''s a start.

OK, but with a line-strip you''d still get the diags, unless you create a seperate buffer to hold the line strip data.
This is really quite a minor bit of functionality, only visible to the map editors anyway so I''m not really willing to put in huge amounts of effort.
