Create Hillshade from TIN

[MatthewBoyle]

Is there a way to create a hillshade from a TIN in ArcGIS 10?  Thanks!

Just to clarify, are you displaying the TIN in ArcScene (in 3D Analyst) and this is where you want to create the shades?

I'd like to display the TIN in ArcMap.  With 9.3 I thought there was a drop down in the 3D Analyst toolbar where you could create a hillshade from a TIN, but there isn't such an option with v10.  I looked through the toolbox for 3D Analyst but didn't see anything that looked similar.

Hi Matt

I don't think that you can do a hillshading on a TIN in 2D. I believe these are your options:

3D hill shading
Since you have the 3D Analyst extention you should be able to open your TIN in ArcScene. There you can perform a hillshading on the TIN. This is only for display in 3D.

2D hill shading
If you have the Spatial Analyst extention you can do the hill shading on a raster - in 2D. So you would have to first convert the TIN into raster.
