Yet another update on progress towards the next version (probably out at
the end of this year, or the start of January). The 'next big thing' is that I've
added
a scripting language to the next version of RsdANIM (so folks can write their
own plugins to get specific effects) - it's only integrated a few days (I'm using
RsdANIM as a testbed for a JavaScript interpreter I'm writing for my day job),
but adding some specific support classes just for doing 3D modelling, animation
and Playstation stuff (just to annoy George, I've included an ActionReplay
class that allows you to talk to the Playstation from JavaScript/R-Script
plugins).

Craig.

Change Log:

[6/11/98]
o Fixed a bug in the "Delete Polygon" function that was causing it to
  delete polys that weren't actually selected....
o Bugfixed the solid/textured display of Poly4's.

[16/11/98]
o The axis locks now affect the resize tool.
o New 'stretch' tool added. To use, select some bits of the model then select one of
the
  axis locks (X, Y or Z only). Now select the stretch tool and you can 'stretch' the
selected polys
  along the axis you locked.

[2/12/98]
o Re-worked the Project manager dialog. The buttons that were in it now get their
own
  dialog/toolbar (so you can turn them off if you want - many people didn't use them
anyway).
o New 'magnet' tool added. Let's you sort of pull an object in a direction. Pretty
cool, not
  sure what I'll use it for yet, but hey.....never mind that eh? The effect is a lot
like the rubber
  Mario face on the intro screen to Mario64.
o The project manager now uses a tabbed dialog. The first tab is the familiar tree
view.
  The 2nd tab is a text edit pane, which you can type JavaScript into.
o Integrated my JavaScript interpreter engine into RsdANIM. Ok, it's missing a bit
of the
  JavaScript language - no worries, I'm working on the interpreter for a comercial
project
  so the RsdANIM version will track the development of that pretty closely. There's
no actual
  interface classes done yet anyway....so you cann't achieve much with it. Look for
big things
  RSN though....we'll call it R-Script in future, so folks don't expect to be able
to do
  WWW access and browser style stuff from it.

[3/12/98]
o Added new pane to the project window. All R-Script functions appear as buttons in
this window
  when you load them (or type them direct into the edit pane), and are run when you
click on the
  button.


[4/12/98]
o Started coding some interface classes for the R-Script interpreter.
  - RSvertex : A floating point vertex/vector class
               This has pretty much the whole functionality of RsdANIM's own
internal C++ Vector
      class.
  - RSrsdanim : A core class to control the user interface with. At the moment it's
only
                got a method to open the About dialog, but it proves the point....
  - RSmodel : Class that's going to represent a whole RSD model. Doesn't do a lot at
the moment though...
  - ActionReplay : Communications class, allows you to send stuff to the Playstation
via a Datel Action Replay.

Sample R-Script Code:

var v=new RSvertex(2.0f,2.0f,2.0f);
var v2=new RSvertex(1.0f,2.0f,3.0f);
var app=new RSrsdanim();

app.AboutRS();

function VPRINT()
{
 app.writeln(v.x);
 app.writeln(v.y);
 app.writeln(v.z);
}

function VSCALE()
{
 v.Scale(2);
}

function VADD()
{
 v.Add(v2);
 app.writeln(v.x);
 app.writeln(v.y);
 app.writeln(v.z);
}

function VDISTANCE()
{
 app.writeln(v.Distance());
}

function VCrossProduct()
{
 var cr;

 cr=v.CrossProduct(v2);

 app.writeln(cr.x);
 app.writeln(cr.y);
 app.writeln(cr.z);
}
