I've tried a few different things with PLY files and no luck. Actually, I'm
not 100% sure if Blender really likes PLY files anyway - you can't even
export color easily in PLY format in Blender. So, I've given up on PLY and
have hacked together a bit of a messy OBJ exporter:
This looks nice. We should incorporate this, or a modified version,
into the AMRSurface object. We used to have a .obj file format
exporter, but I (incorrectly, it seems) thought the PLY format, which
can be in binary and is thus much smaller, had feature parity. Would
you be up for making this a bit more general, and then adding it to
the AMRSurface object?
I'm probably doing the colors wrong, since there's likely a nicer way to get
actual "face" values then just taking the value at 1/3 of the vertex values,
but it worked, so I didn't mess with it too much.
There is a simpler way, but honestly it's pretty non-intuitive and I
think the face/vertex sampling in the AMRSurface is a bit clunky. If
it will sample at the faces rather than the vertices. This is also
the default behavior for getting data through the dict-like method:
which should be face sampled.
A few other things: (1) in theory, this can set transparencies, but I
haven't got that working as of yet, (2) the default specular (ambient?)
color settings make for a bit of a washed-out view in sketchfab:
, (3) the .mtl file is a bit too long since I'm
essentially setting each face as a different material, when one would just
like to use 1 material per color and set all the faces with that color on a
specific surface plot to that material, but I haven't got that bit working
(2) Is this something that can be controlled by the materials editor
Quick followup -- by changing the "Rendering Options" to "Shadeless"
was able to see things a bit better on Sketchfab.
(3) Ah, interesting. One could do just 255 materials,
and then that is now the colormap.
This is definitely very interesting, and would be a huge upgrade for
our Sketchfab / Blender / etc capabilities. Thank you for sharing all
