3D: Conversion into vrml files

[Nicolas, Y. (Yves)]

Hi,
I'd like to print rendering pictures obtained with ImageJ plugins in 3D , however the 3D printers normally use .vrml files (Virtual Reality Modelling Language), I wonder if someone would have a converter from Tiff file to vrml file.
Thanks
Yves

I think this problem is ill-posed: Tiff has raster data, i.e. volume data
sampled on a regular grid, whereas VRML handles vector data, i.e.
_surface_ with at least float precision.

If you want to extract an isosurface from a Tiff, and have that as a
VRML: that would be possible (I have the building blocks for such a
plugin, but no working plugin).

Ciao,

Hi there,

Since I am working on camera photo taking from real
field, it makes me more difficult to extract objects
from image accurately.

I tend to use substract function to get rid of
background image from original one, which I guess will
help me to extract object more efficiently.

I following the "test stack" sample in the following
plugin

http://rsb.info.nih.gov/ij/plugins/multitracker.html

to create background image, which essentially using
copy/paste a small piece of background to cover the
target object in image.

I wonder if there is other better way to generate
background image automatically.

thanks your time,

Michael,
