Hi !

With the permission of Vahur, I've released a new version of POVMan with
an updated version of the cloth patch.

Sources update, a windows exe, and an updated documentation are
available at:

http://tofbouf.free.fr (clothray section)

English version of 2 first tutorials are also available.

This version also fixes 2 bugs:
- the #default directive parsing bug I've pointed out some days ago.
- the tranformable warp crash found by Fabien Mosen (somewhere in this
group).

Comments and bug reports (even in documentation) are welcome.

Bouf.

Hi,

I'm using the new Windows exe version 0.71.3. Having lots of problems with
Clothray stuff.

I downloaded 'nappe.pov' from the English tutorial, and it won't run...I got
the
following error:

#declare vect = clothsim <----ERROR

C:\Program Files\POV-Ray for Windows v3.1\Clothray\wpovman\nappe.pov:42:
error: Cannot assign uninitialized identifier.

It seems this scene file is for the earlier version of Clothray, and hasn't
been updated. I tried changing the file by following the tutorial, but had
lots of problems. gravity -.4*y and damping .9 give errors when used. I
finally got the simulation to run, but then received an error saying that
there were no triangles in the mesh.

Also, there are many spelling mistakes in the actual code on the tutorial
i.e

simcloth {
    environment Table
    friction 0
    gravity -.4*y,
    damping .9,
    intevals 0.03   /// Missing the 'r' in intervals
    iterations 50
    input "nappe.cth"
    output "nappe.cth"
    mesh_ouput "nappe.msh" // Missing the 't' in output
    smooth_mesh on
    uv_mesh on
}


Help please.

Yes, that was the case. Updated now.

What kind of errors ?
If it's errors in the resulting triangles (coordinates like +INF.000000
(that's the "NaN is not a number" equivalent....)), try lowering
"intervals".

Hu ?  Try the updated scenes, I've just run them without problems on a
unix platform, and I think that it's OK on Windows (I see no reason it
won't).


Thanks for typos, corrected now.

Bouf.
