[WIP] '69 Dodge Charger

thomthom

I couldn't help myself playing around some more. Bulked out most of the read fender.

Contemplating how to approach the door - it's had some very complex geometry. I remember when I was doing the 3ds model seven years ago that I was bending my mind then as well.

Detail of the door:

Extract from the old 3ds max model: (The mesh has many problems - a lot of triangles...)

I think I need to print this out and trace over some paths with tracing paper. Not sure how to make the loops flow.

The 69 Chargers don't have a frame, just a few anchor points on the underside of the body. Here is a pic from the rear that shows the front rear spring mounts and the rear torsion bar mounts.

Hope it helps.

That's some good references.

That's a great start.
Few things that is good to keep in mind when using artisan :
1.Keep all the diagonals oriented in the same way
2.If you can't go all the way quads then you have to have all the way triangles(at least don't let single quads in the middle of triangles), otherwise the smoothed geometry won't be that nice .

Keep it going !

Thanks! That's good to know. I only did some quick tests with Artisan to see how smooth the edges where - around the wheel well etc. It did strike me how seemingly random the Artisan mesh was. I understand more what's going on now.

I haven't inspected the diagonals at all as I've worked mainly on the low poly topology in quads. (When I talk about quads I talk about QuadFace Tools quads which can be non-planar.) Would have been nice if Artisan understood these quads and could perform subdivisions based on that instead of the underlying triangulation.
I've been looking up Catmull-Clark subdivision and I'm tempted at trying to implement a version that makes use of QuadFace Tools's type of quads.

Go for it! I'd buy that

i'd buy that twice!

Thank to this:

I can now make this:
Catmull-Clark sub-divisions compatible with QuadFace Tools

Great day!!! Wow Thomas, I can only wait to see what comes next out of your mad scientist workshop!

Wow. Wow Again. Wow Some more

Now THAT is interesting. Thanks for the tip.

Well, that looks awesomely cool ! Very smooth and arranged geometry !

You are welcome , Bryan !**

The mesh is still the same as in the sample I posted earlier - lots of non-planar quads. But that doesn't matter - because the mesh is treated as quads. The underlying triangulation is ignored. One less thing to worry about.
If only I understood the math - Rich got me really interested in edge weighting vs crease loops. I'd be very nice to be able to the edge weight creasting instead.

Got a cold brewing - so no modelling today.

Next task is to work out the loops for that door.

i think you must see this one,, http://ixlrlxi.livejournal.com/113673.html#cutid1
but sorry in russia language,,but you can watch "the step by step" of his action.
(sorry my poor english),,

good luck man

Yea - that guy makes some amazing models and really nice renders. I've been following him on deviantArt for a while.

oh my god! a dream coming true.
i don't know if you will make this for free or commercial, but i will give you a donation in both cases.. i think you really deserve it!

The cold caught up with the and I'm home sick today. No working today either. Though I had to play around for a couple of minutes with the sub-divisions:

When you subdivide it should also be possible to transfer UV mapping. Which would be another cool thing.

But I digress - need to get back to modelling this car.

hope it passes quickly!

But think of all the cars (to say the least) the rest of us can model if this makes it out of your lab

I DL'd and I've been trying out a Catmull-Clark tool but it does not give such good results with or without quads. Sry but I can't figure out what ruby it is as it is not named clearly and doesnt show in any search of text.[/off:3dee1n0w]
