for the spec of the meshmap file it indicates the first value can be 1 or 2. The value one is panorama, two is fisheye imagery.
In the vuo warp fisheye module, does it process #1? Does the first value alter the xy-uv processing? Is the first value actually used for something besides metadata tag?
Is there a way to put a
Is there a way to put a comment line in the file?
for example, '#' in column 1?

Paul Bourke wrote the spec for this format: http://paulbourke.net/dataformats/meshwarp/. As far as we know it's just metadata; in Vuo, at least, its value doesn't affect the rendered output.
The spec doesn't include a way to add comments.
The response from Jean Marie
The response from Jean Marie above is correct, the first number indicates the type of image projection the mesh is intended for. The way the warping is performed is not dependent on that value, it was originally added as a way of indicating other things, in particular - For some image projections wrapping may be applicable while for others it isn't, eg: circular panoramas vs fisheye. - It can be used to indicate what forms of navigation are appropriate, for example "roll" may be applicable for a fisheye but not a perspective image.
And yes, I forgot to add the ability to insert comments. The format was dreamt up as something I imagined only I would use for my own projects/software. Then it "escaped" at which point I couldn't add features without breaking code others had written ... including the implementation in QuartzComposer. If I had thought ahead a bit more I would have included comments. Sorry about that.
