I am going to pause here, and answer any questions, and hope that I have not made massive errors in my calculations. There are many free Poser vehicles if you would like to test the calculator and make an animation, and on Tuesday I will be releasing the tank in the first post for free, so you can test the tank animation part of the calculator. I hope to have the whole tutorial up by Tuesday, by I am leaving the calculator to last in case people need some alterations, or added functions. So please, ask if you need a better explanation, that is the only way I can tailor the calculator to your needs. PS. The calculator will be free, just in case you were wondering.

Well, first off, for the Yanks, could you also include Imperial measurements (probably be better as a separate file). Also, someone with OpenOffice.org should give this a try to make sure Calc can use it properly.

Thanks Cath. I am making improvements to the calculator as I go along, and hopefully I will be able to add another few useful functions, such as a Poser units convertor (although this will only be useful when moving the vehicle along the x or z axis, not a combination). I am also going to see about uphill and downhill calculations. If you can think of any other useful functions that need to be calculated for Poser, or converted, will you let me know. R_Hatch, I think for the Yanks I will just make a seperate version with everything in those primitive units, lol. I will sub-name this one the metric version. I am going to test it on a few other spreadsheet programs to see how well it runs. I doubt if it will work on many, as things like Pi are not standard in all spreadsheets. Thanks for the input.

Moving tank tracks at last YAY...just a quickie qtn Helgard...I'm afraid mathematics was not my strong point in school, but what is Pi???? Cheers, keep up the good work :-)

"what is Pi???" Now THAT'S going to be a long answer!!!! ;-0 -jjsemp

Pi is ratio of the circumference to the diameter of a circle

Ooops, I made a mistake. That's what happens when you don't sleep for two days. Pi is the ratio of the circumference to the diameter of a circle. In my Pi calculator I made it the radius, not the diameter. My original idea was that it would be more accurate to measure the radius than to measure the diameter and make sure it passes through the centre, but I forgot to add in the multiplication to get the figure back to diameter. Good thing I didn't release the calculator yet. OK, tutorial will continue in a few minutes, just need to get some drugs (caffeine and nicotine). As to the question of "What is Pi?". Pi is a number that has still not ever been calculated properly. The closest mathematicians have come, is a number 400 000 000 000 digits long. The number was first used by the Babylonians (2000BC), who calculated it at 3.125, and for modern use the number 3.14159 is considered acceptable for everyday use (Everyday use? Yeah, like we do use it everyday, lol!!).

OK, there is one more thing before you can render. Something specific to Poser. If anyone can guess what it is, they will win a free copy of the free JagdPanther. I will keep you in suspenders for a while, because I have to make some more pages of this tutorial.

I have received an e-mail asking about the differing opinions as to Poser units' values. This is one case where this does not matter. You are trying to achieve a believable speed for your vehicle, and a relative motion when compared to the rest of your scene, so that your wheels do not spin in one place, or move to slowly for the forward motion. So whatever scale and Poser utility you are using, your calculations will be correct, because you are calculating a relative motion. I will see if I can make an example using differing scales to show you that this does not matter.

Here is a simplified version of the final calculator. The final version will look better and have many more functions. So this is just a beta test version for you to find all my mistakes, lol.

Wow! This is an incredible tutorial. Thanks for sharing. I hope everyone remembers to celebrate Pi Day, 13 days from now. That's right, on 3/14, you should bring a pie into work and share it with your co-workers. P.S. I don't mean to spoil your mini-contest, but the JAGD Panther is available for free for everyone to download. :) --John

I'm really interested in how to make non uniform tank treads for a sci-fi character. Are the tank tracks separate objects, or are they a "loop"? Sounds like something fun to tinker with.
Way too many people take way too many things way too seriously.
