Hi all.

Does anyone know how i could go about creating a wireframe model ..
(eg, like what you see in wireframe mode) ?
Preferably a quick and easy way, the model i want would be a 36 sided
torus - that's a lot of faces to do cut out !!

Cheers all.
Pete

Drawing wireframe vs solid is a render state, not necessarily a model you create. So you'd have your torus, and in whatever engine or other software you use, you specify it to be drawn wireframe.

Essentially what the GPU is doing when you enable this state is it draws the geometry as it normally does - the outlines, but does not fill in the surface when the shape is rasterized. Afterall, you define your torus as a set of vertices, so it makes sense you should be able to tell the GPU how to rasterize that shape into a bunch of pixels.

An alternative would be to specify your torus as a bunch of lines (e.g. linestrip or a linelist), then quite obviously it would appear to be wireframe, although I'd just stick with the method I described above.

So in summary, this is really up to whatever software you're using outside of DeleD.

You could do it by creating your model. Go into face mode select all faces then click inset and in 3d view move your mouse very little so faces inset inwards. While faces selected press delete. There you have a wireframe type model.

Of course depending if the engine you are putting model in can show 2 sided textures on polys or not, this might not be what you need. To then extrude edges and fill faces would be a pain if it cant.

Yay !
that's what i wanted, thanks fik

(except it needs to be in polygon mode - not face mode - to get
the inset option !)

(thanks starnick, i did actually want a frame type effect just like
fik suggested.)

Cheers

Not reaaaally wireframe, at least in the way you likened it to DeleD's wireframe mode. However, I see where you're going with fik's suggestion (it's kinda faking it and giving you the ability to control how thick the lines can be somewhat or giving you the ability to texture it).

To deal with 2-sided polygons, you can either turn off back face culling in your app -or- clone the model and flip all the polygons if you want them to use a different texture, maybe shrink the cloned model a bit so you won't run into any Z-buffer flickering issues (or tweak the zbuffer states when you're rendering it).

A 'Cheaper' method would be to select all the edges and extrude them by a very small amount, making the faces two sided. This should at least save on polygons. Delete all the large polygons, to reveal the 'wireframe' shape.
Selecting all the vertices, then in properties, set the colour to whatever you want, should render as you see it in DeleD, in most programmes.

I've added this screenshot:

Thanks AWM, when you say delete all the large polygons .. is there
any way to delete them all in one go ?
I've tried a few things but they always delete the whole model.
I'm all for saving polygons !

Thanks for the offer AWM, but i may have to re think the plan ..
I've tried most of the tricks you chaps have suggested, and they all
look good, but my polygon count is starting to get a bit high, deled
is getting abit laggy and blitz3d is giving me memory access violation
messages ...
The thing i'm looking to create is a coloured glass torus with
either 36 or maybe 108 (to facilitate extrusion) segments, but
with the edges a different colour so as to give some structural support
(it'll be the cover of the monorail track going round my space station.)

Here are some screen shots :-
From outside...



From the track (where the monorail will be)...



Cheers all.

For that, wouldn't it be easier to make a texture with 2 layers?

Layer 1 would be your wire frame.

Layer 2, blue with transperancy set to 50 (or however it looks best to you.)

This way, you don't have all the polys. Those frames are being changed into a ton of polys.

Edit for clarity: Just make your tourus with the number of faces you want. (make the minimal amount) then texture the tourus with your new texture.

Edit2: EGADS. 30 minutes to load the forum???

Ok...now for the real edit:

This is a quick and dirty (very) example of what I was refering too above:

Make a tarus in deled, set hollow and texture.
segs: 16
polys per seg: 12
outer: 3
inner: 1

Total polys: 384
Don't mind my texture. It sucks as I am no artist.

Here's the pic:


Hope that makes things a tad clearer.

Moving forward with Truckers idea, I've created a similar sample, but also the texture that may best suit you. Anyone is free to use this texture, it is a PNG format, which must be set to Alphablend in DeleD to work correctly.

You are going to have to spend time in UV mapping to get the texturing orientated correctly.
Try using the latest 'Projection Mapping' plug-in (see http://www.delgine.com/forum/viewtopic.php?t=4535)

Or, use this Texture mapping plug-in http://www.delgine.com/plugins/viewPlugin.php?catid=41&catdesc=Extensions&contentid=34 whichever suits your workflow.

Screenshot (Not pretty, but shows what I/we mean)


The texture I created and used, which anyone is free to use anywhere.

Simply Right Mouse Button click the picture, choose 'Save Picture As', to your HD. It is a PNG format, so you can edit it in your favourite graphics programme, and alter the colouring.

EDIT:
To reduce polycount further, all the polygons faces beneath the solid floor on the inside of the Torus, you can delete as they are not seen.

I really do wish I had an artistic thread in my body. That looks absolutely awesome AWM.

Nice one AWM Mars
I love the way you take the time to help .
