exprfill method of jit.matrix is not.

We could probably document this a bit better, but here is how your 

exprfill message will need to be formatted:

exprfill 0 "norm[0]",exprfill 1 "norm[1]", bang

the exprfill message takes an extra int(plane) argument before the 

expression to specify which plane is to be filled. This is slightly 

different from the way that jit.expr accepts messages.

Syntax for exprfill is different to support only writing into one plane.

If plane number is absent the same expression is written to all planes.

Sorry for this oversight in the documentation. Will fix.

I would like to be abble to xfade between 2 .obj files (matrixoutput 

1 send to a jit.gl.mesh for a geometric shape)

I tried the same trick as with gridshape and mesh but got strange 

So as .obj files describes forms based on triangles or etc. is there 

a way to extract info to make model work as gridshape

or do i have to make the mixing directly with the lines codes 

describing .obj files to achieve a kind of morphing?

Dear list,
I would like to be abble to xfade between 2 .obj files (matrixoutput

shapes out of it.

Every suggestions are welcome
Thanks

a) they have exactly the same number of vertices

b) the vertices you want to morph back and forth between are the same 

This sounds hard, but, what you should do is

a) create a large sphere with the maximum number of verts you will want

c) copy it as a seocnd file, open it and sculpt out the shapes you 

want by extruding and displacing the points/planes/surfaces of the 

d) do the same for the second model, and everything *should* line up.

Ive done this with Wings3D, and its basically worked.

a) they have exactly the same number of vertices
b) the vertices you want to morph back and forth between are the same  
index in the list.

a) create a large sphere with the maximum number of verts you will want
b) save it and dont loose it
c) copy it as a seocnd file, open it  and sculpt out the shapes you  
want by extruding and displacing the points/planes/surfaces of the  
sphere.
d) do the same for the second model, and everything *should* line up.

exprfill vs. jit.expr bug? misuse?
