Paddle Steamer engine

Lol. Classic
Interesting thing about using gears to decelerate, it actually cools the engine really quicjkly. If you ever get to the top of a large hill, (or mountain ;) ), and vehicle is overheating, dont stop at top of hill to allow engine to cool. (they actually get hotter doing that). Best thing to do is go down the other side, using engine/gears as brakes. Used to do a small mountain here, (takaka hill), would be overheating at top, then go down in second gear and engine was back to 'below running temp' in only 5 or so minutes. Could 'literally' watch the temp gauge drop'. (funny that)
The '7 litre' is in my bus. Its a Ford Commander, 11.5 metre 'home'
Slightly off topic here, hope you don't mind, but was revisiting Terranim8or yesterday.
(Leslie done awesome stuff there. Needs more recognition. Should be linked at Anim8or Home page.)
Was thinking, when it comes to 'Fire' for your 'steam engine', maybe worth a revisit.

(but then, you probly got some other 'magic' way of making fire... ;)

Yep, Carrara I would expect for Steam, smoke and (heaven Forbid Fire!!) If I Know Tony ;)
ENSONIQ5:
Carrara is very tempting... but if possible I'm really trying to keep this all within Anim8or so I don't have to re-jig the motion (also just because it's been ages since I've done an Anim8or-only project.... though I am remembering why that is!). I've done smoke before in Anim8or, it was a bit rough but the concept might be transferable. In fact, since these engines burn redgum blocks (Redgums are massive Eucalypts that grow along the banks of the Murray River) rather than coal they don't actually smoke much when nice and hot. I haven't really thought about the fire yet, mostly it'll just be an orange/yellow glow with a few flicking tongues of flame licking out when the door is opened which shouldn't be too hard to simulate. Some experimentation is in order for this I think... which is the enjoyable bit about projects like this!

Don`t know if you have this controller script , but may be useful to dissect. Originally posted by Kubajzz on CG-Nation which has now evaporated.
--- Code: ---/*--Pendulum script - created by Kubajzz--*/
float $Period, $AxisAngle, $Amplitude, $Brake, $Decrease, $time, $finalamplitude, $stopmoment;
/*--Replacable parameters below--*/
$Period = 1; /* Enter value in seconds */
$Amplitude = 0.2; /* Set the range of the movement */
$AxisAngle = 0; /* Set the horizontal angle of the axis */
$Decrease = 0.3; /* If you want the pendulum to lose it's energy, set enter any value higher than 0 (values 0 - 0.5 recommended); set 0 for constant motion */
$Brake = 0.05; /* Maybe you want the pendulum to stop swinging when ti loses it's energy; set value 0 - 1 (values lower than 0.1 recommended) */
$finalamplitude = $Amplitude*(1-tanh(time*$Decrease));
$stopmoment = ($finalamplitude/$Amplitude)*1/$Brake;
if ($stopmoment<1) $time = 0;
else $time = 0.7854*$finalamplitude*cos(time*3.1416/$Period);
$orientation = (sin($AxisAngle*0.0174533)*sin($time), 0, cos($AxisAngle*0.0174533)*sin($time), cos($time));

ENSONIQ5:
Thanks Kev, it all makes sense in terms of operation. Just having trouble understanding quaternions...slips straight through my head without leaving any impression at all! That's not quite true, I understand the basic concept, but wrangling quaternion/roll+pitch+yaw conversions requires a higher level of mathematics than my hardened old synapses can handle. I'm pretty much abandoning scripts for some things and instead making use of invisible rotating objects and the point-at function, which is far easier to manage and adjust. I'll still be using scripts for some things (rotations, reciprocal sliders).
