Re: LOGO-L> 3D Logo source ?

[George Mills <mills@softronix.com>]

Sorry I could not reply to <roy@unice.fr>

Your request is a little ambiguous so I'll try to cover all
the bases.

There is source for an implementation of Logo with 3D
capabilities called MSWLogo available at www.softronix.com
(this is Borland 5.02 C++ source code).

There is Logo code written FOR a Logo implementation
that supports 3D called MSWLogo that is included with
the installation of MSWLogo at www.softronix.com.

However the current release only supports "wireframe"
3D modeling and requires you to redraw
each "frame" as you fly the turtle "eye" through 3D
space. But you can record each frame and play them
back at as fast as your computer can go.

The new pending release of MSWLogo 3D V6.3 will
support solid shaded objects and requires a certain
skill level (Grade 10 math or so?) to define 3D surfaces.
Another advantage is that you can fly the turtle
through your scene without having to redraw it. However
if you have even a moderately complex scene it will
take time for each frame and you'll have to resort to
recording each frame. See the recent post I just did
that shows a 3D shaded box being folded into
the shape of a box.

This latest release is available as a BETA
(very little documentation on the new "shading"
capabilities, just several examples) and the Borland C++
source is not available as yet. The release version
with shading capabilities should be avilable in
a few weeks.

You might want to look back at several of the posts
on comp.lang.logo that I just did.
