tyre/tire selection

[zimluura]

The tire and wheel are 180° rotated around up-axis(z-axis). I haven't changed this yet. There are two ways to deal with it. Having four meshes and mirror them accordingly on setup using negative scale. Or keep two meshes front and rear and mirror them at draw time(mirror the scenenode). I am undecided which is the better way to do it. Do we want to have four distinct wheels(meshes)?

i had thought just two meshes (front, back) for tires (might be able to optimize that more, lots of cars have the same size tires f&r), and then two more meshes for front and back wheel, but alter the drawing routine depending on the content being rendered. would that mean a different scene node?

How should we deal with flangeDisplacement_mm? I have it hardcoded atm.

i had thought that each wheel style would have it's own definition file maybe. or maybe each style would be in one big definition file. and there the flangeDisplacement could be defined by the wheel artist, if they so desire.

There is a better idea. Create the spokes mesh assuming a rim width = 1.0. We will scale it using the real rim width to fit it to the tire.

this sounds like it will work. i think there might end be a problem when i get the brake rotor going...which i should go finish up now...maybe gotta get some caffeine first. i was leaning toward all the wheel vertexes being just barely on the + side of the x axis. thinking if we did it that way we might more easily be able to position the wheel_edge. but then we'll still run into problems with the rotors... i'm good for trying this, so long as none of these positional thoughts raise a red flag for you, i'll start doing more stuff after i get the rotor built.

Kind of obvious but width also needs to be handled.

i think width is handled for the time being. give it the tire size and it automatically spits out a perfectly sized wheel_edge. i'd like it to be more realistic, but i think there needs to be some kind of player parts inventory and part buying system before it can really be done the _right_ way. or am i misinterpreting you?

musing: a while back i was trying to make a garage scene in blender, maybe to one day turn into a track where you could see the cars you had bought. when/if there is a parts inventory we could have all the spare parts stack up in the garage to give it clutter.
