Site model not smooth

Recommended Posts

I am creating a DTM from a third party survey. It seems accurate enough and there are plenty of points but the resulting DTM is "creased" and looks awful.

There is a "smoothing" section under the properties of the DTM but this only seems to effect the 3d contours.

How do I smooth out the mesh object?

This may be same as Matt's, or not, but I am curious how to round out the flattened contours on the DTM. I highlighted a few of them on the DTM. Source data is rounded and has plenty of points.

Sorry, my DTM now looks passably smooth and I'm not sure when it happened.

I was working on some texture beds and I suddenly noticed the creases had gone.

Maybe it takes a few "updates" to make it happen, maybe the "smoothing" did work.

Sorry I can't be more helpful. I'm baffled but happy with the result.

Basically it looked like a piece of paper someone had folded and then unfolded. There were sharp steps up where the changes in gradient occurred.

Basically it was going to have to be camouflaged to get away with it..

But now it isn't and I still haven't got a clue why...

if mesh smoothing is not working, it could be an indicator that your model is too complicated. if that's the case, try simplifying the original site data.

cheers,

Tamsin,

I did turn it on but it seemed to be saying that it only applied to the 3d contours. It certainly didn't make any difference to the mesh object.

At least, not immediately. It seemed to work after a few more updates.

And then stayed smooth after I turned it off again.

I must say I don't understand quite what happened...

I'm having this same issue, turned smoothing on and I can see a slight difference in contours but not mesh model... hoping if I update a few more times something miraculous will happen!!
