  Any "parameterised" modellers (Message 1 to 6 of 6)

When I create objects I like to declare names for all the dimensions so that
I can easily adjust the model later. Often the relative placement of objects
is
calculated mathematically from these variables (e.g. to ensure tangency or
whatever).

Are there any 3D modellers that allow you to do the same thing? My
experience
is very limited with modellers so perhaps I just overlooked the feature, but
it
seemed to me that I was always required to specify precise dimensions,
without
any kind of indirection.

Not that I mind writing the script myself, but such a tool could be useful.

Windows or Linux will do.

Thanks.

Don't know if I understood right, but in Moray you can declare the objects
(of course;), give them names, and group them ...

when in groups, the objects are placed relative to their parent objects...
furthermore, every object has it's own relative coords, that can be adjusted
...

but maybe I understood wrong ...

Sorry if I was a bit woolly. I want to do the equivalent of this:

#declare Major = 3.0
#declare Minor = 1.0

torus{ Major, Minor translate<0, 0, Major*Minor>}

Now I can alter the model just by changing the values of
Major and Minor. IIRC Moray requires me to enter all the
dimensions as numbers - no expressions allowed.

Thanks

THIS is the one thing i'm missing as well ...

Sced may be able to do what you want.

Obviously, the best and most useful software is only available for Unix ...
(except POV, of course)
