Horizontal / diagonal wheels

[Daniel3D]

Something in the shape ideas topic that should have its own.

I don't think i did anything wrong, but the game crashes as soon as the car begins to move.

How odd. I have tried replacing the STLM02.P3S with the 3SH you have attached, and it worked fine here; no crashes. (The flickering of the wheel primitive is a fair bit more noticeable when it is on the top of the car, but I guess there isn't much we can do about that.)

I cant get my test copy back to normal. but the zakstunts copy does run fine.
found the bug, i inverted the wheel on top.

fixed that and now it looks fine.

Here is proof that you can place a wheel horizontally.

Did some more testing (while working on the crash sprite bug).
If you can do the calculations, (don't have to be exact) you can place a wheel at any angle.

I did this rotation without calculating, just looked ok enough.   

So in theory you can make a steering wheel out of it.

The ellipses of that wheel are at an angle in the view. That contradicts my hypothesis that wheel deformation occurred because the ellipse-drawing primitive Stunts uses might only be able to draw them with their axes aligned to the screen. I'm amazed that Stunts is actually using a routine that can draw tilted ellipses and still be so fast!

[Daniel3D]

It does make sense because it's an 'open' track area. With ramps and all kinds of camera possibilities.
So odd angles are to be expected.
But if you rotate the free camera around the car you see there is a redrawing every X amount of degrees.
So (I think) it is kinda like your hypothesis but more elaborate with several orientations but a limited number of options.

Makes me think if a dune buggy with a roll cage made out of stretched wheels and spheres at the connections would work..
Only 6 vertices for a beam, saves a lot of vertices, but don't know how the engine will handle it.

How you calculate it ?

[Daniel3D]

I didn't. I used some grid pattern paper. Placed an transparent sheet on top. Drew a side view of the wheel on it. Then rotated the sheet and used that as indication for the new coordinates.

Ok finally I used a 10 polygons for the propeller of Airwolf

It's a better solution for this than a wheel I think.
