Sum of torque

Hi EOW,
Blitz3D is a basic compiler with an embedded 3D engine for DirectX. It is rather easy when you know a bit about programming. But it is not for free. Some years ago there was a free version with a 1000 lines of code limitation, but now I guess there is only a 30 days trial version.


There is also freebasic with some 3D extensions, but I  not sure if it has all the important features, like parenting one object to an other.


There may be other solutions, including Blender, although Blender is very unintuitive and hard to learn.

CORRECTION!!! BLITZ3D is now Freeware!!!

Totally reccommended! I paid 100$ and never regreted a thing!

Edit: BTW, here you should find several physic engine extensions, like Physix, Bullet and others:

The blitz3D compiler allows to use those 3rd party DLLs with a "wrapper".


Basicly it may be useful to search the forum using the word "physic"

With Blitz it's possible to have the sum of forces, the energy, etc ?

You have to add one of the physic engines (see my last posting), and then yes, to some degree they try to simulate physics. Some are really good, probably even with friction parameters.


Ok, this is not the best, because the best physics simulations usually cost $$$. But it is interesting and may be very useful.

With a stem with mass, the left half fixed circle can stop the stem. With a fixed spiral, the stem can have a massless, the spiral gives always a prependicular force to the stem. There is friction between the stem and the red disks. Forces F1 and F2 are forces from friction between the red disk and the purple stem. Forces F3 and F4 force the purple stem to be on the disk, F3 and F4 cancel themselves, the spring never move, it don't lost energy.

It's ok because S<pi*R
