How to create "ASCII Scene Export" files from a MATLAB mesh

Hi,

I would like to generate an ASE (ascii scene export) file from an image that I've read into MATLAB and plotted as a mesh.

Ideas, anyone?

Hi,

Assuming that you have access to something that can render such
models, I suppose you can save them as well. As I have no experience
with this format, what I would suggest, is to create a plane in the X-
Y plane (a flat rectangular surface) with side lengths set to 1 and 10
vertices per dimensions (so that it has 10 by 10 vertices on a uniform
grid) in one such editor, save it as ASE, and try to understand the
result.

If you did this, and are capable of generating rectangular meshes in a
certain size, and with a certain number of vertices, than all you need
to do, is to create such a file with the Z coordinates of the
respective vertices set to the intensity values of the image (or some
transformed version of it).

Hi,

Thanks for the response. This is what we're currently trying to do, writing our own export function.

I was hoping, though, that someone out there already did this, since this is really only a small part of a bigger project.

Anyway, thanks!
