Does anyone know of a site for a model of Mt. Everest. Or perhaps, a DEM file. If there is a DEM file, what is the best method for converting that into a Lightwave object? Thanks in advance.

Have a look at this:
The link is basically an extension to google Earth that allows you to download parts of the globe as TIFF elevation data.

Accutrans 3D (micromouse.ca) is the best (almost) free way to get DEM into LW without another CAD or 3D app that I know ...

Hey Mike - how would you propose turning that tiff into an accurate 3dmodel :) ?

Well, the SRTM data are just geotiffs, so you can crop in Photoshop, displace in Layout and then reduce the polygons in Modeler if you need to.

There are plenty of options here though- my favourite is using TextureScape using a displacement image: http://amber.rc.arizona.edu/lw/texturescape.html

I have been only using grayscale displacements (256) .. does LW automatically see the coloured goodness? (Sorry about all the questions, this is a whole lotta good news for me ...)

Coloured... no. But (depending on the image format) it can read more than 8 bits (256 values) of greyscale.

MIcro dem is the way to go - free and easy to use. You can export the DTED/DEM file into a OBJ and then merge and reduce polygons. Just goggle microdem.

cheers

Thanks Martyn - how's the weather in the capital?

Well its fine and sunny today - I actually live on a Farm 85km South of Canberra and commute everyday - due to the drought (need the money to feed the stock -don't know what will happen now there is no grain crop), it was cool and foggy down there at 6 oclock this morning when I left.

Sorry to hear about the stocks and crop, are you still working at Defence Dept?

No - the Public Service is not the place for me, or should I say my type, I work for a company making simulation data bases and doing imagery analysis tasks in support of the RAAF and the Emergency Services - not looking forward to the fire season this year.
