driver mesh

yeah, i'm basing my opinion on mass from how the driver adjustments are happening. 'cause his position *is* based on a mass position...

i assumed his visual reference model was being drawn where the mass is as far as the physical calculations are. but if they're not, i can't look into it too much without source diving. unless maybe i could try to make the driver weigh a few tons and then position him high and to one side to see which way the car tips...wow that sounds like a fun test to do.

<a>
so my 9000kg driver caused the car to fall through the track. probably stressed the suspension so much the car bottomed out in less than 1 frame and that took the collision box below the track...of course after that it was pretty much a mess.

<continued>
with a 400kg driver 2 meters up and 4 meters to the negative x the car seems to do a wheelie when accelerating forward. with a 200kg driver 4 meters positive x when i brake i get the back wheels into the air and the car does a forward somersault.

so i think x is maybe forward and back now, with negative being towards the back

when i place a 200kg driver 3 meters up and -4 meters of Y, the suspension on the right side seems compressed. and with positive 4 Y the suspension on the left compresses.

the nature of these tests does assume that positive z is up. which seems to jive with how the car handles with a 200kg driver 5 meters underground. and also how it's very easy to flip with a 200kg driver 5 meters up.

so my revised idea on how mass positioning currently works is this:
x = back and forward, negative being back
y = right and left, negative being right
z = down and up, negative being down


// edit
for the record, i'm in favor this:
x = left and right, negative being left
y = back and front, negative being back
z = down and up, negative being down

also if all the coordinate systems get all synchronized. then the driver-view position can be computed from his mass position + a vector for every vehicle. and that vector can be set in a .driver file...though i think it should probably get the extension .ini, or maybe .cfg, or .config, or some other something. mostly because on a file system if you see something with a .driver after it you're going to wonder what the hell driver model that it. solaris maybe?? ok i'm digressing to the point of useless rambling. i'll stop now.
