1) For a full 3D GIS, the better is GRASS GIS, look at Screenshots of 3D data management or From drone-aerial pictures to DEM and ORTHOPHOTO: the case of Caldonazzo's castle, from example. Some examples (interactive: you can scale, rotate the representation and many other things) : DEM with 3D points: Draped raster on the DEM Draped geological map ...

Tips: Note: Your computer has plenty of spec: Develop a full or partial disk cache whenever possible. Disk caches allow data to be pre-rendered for optimum ArcGlobe/ArcScene display performance. Store ArcSDE/ArcScene data sets using the Cube projection This will avoid pyramid resampling and data reprojection for ArcGlobe. ...

Have you ever created a building model using ArcMap? I'm confused as to why you would choose any of the ArcGIS products for this application, as it was designed for geographic data, not 3D modelling of structures. Google Sketchup is very easy to learn and there are some very good tutorials on their website and on YouTube - I'd highly recommend it and would ...

There is some VB code on EDN "This tool contains a toolbar providing functionality to create text labels in the 3D environment of ArcScene. The text and location of the labels of the toolbar can be originated from features in a layer, as well as by user defined positions via mouse clicks. Dialogs are provided to allow the modification of the rotation, ...

I have made ​​the experience that the problem can not always be solved completely. But if you use layer's drawing priority, it gets better. Please try to use the layer's drawing priority: In ArcScene you can change the drawing priority of each of the layers being displayed, so the more important layers will render on top of the less important layers. ...

You can also use ViziCities (in the browser using OpenStreetMap, WebGL and JavaScript), though it only supports 3D buildings and geographic features right now (data layers coming soon). Disclaimer: I'm the developer behind ViziCities, though my only intention is to let you know about it and let you decide which tool is best for you.

Take a look into QGIS Plugins for that purpose. qgis2threejs is a experimental python plugin that is getting better and better as we speak. It allows you to transform any internet browser with WebGL into a 3D visualization tool. You can check the code here: https://github.com/minorua/Qgis2threejs Also check this usage example done by Anita Graser: ...

When you downloaded the data what format did it come in? By definition, if the data is a raster format, it can be considered 3D data, as it has a x,y,z value. If you are looking to have it extruded in ArcScene then you will want to do a few of the following things. Assuming your data is in a usable raster format (ie: GeoTiff) then you will want to do the ...

You've got a projection issue. Chances are you've not specified the projection of the DEM correctly. There are typically two indicators to this and you have both: You have spikes. You have a cell size that looks like: 0.000278 (it should be a whole number). So make sure you've set the correct projection for the DEM as well as the drape (if memory serves, ...

From my experience (also not a remote sensing expert), it's very hard to get accurate building outlines. If it is not a huge area, it might be worth manually tracing the buildings and then doing a spatial join with the LIDAR data to get the building heights.

Try to convert polygons to lines.

The easiest way I know to do this is to digitize a path around the object in question in ArcScene (make sure your polyline contains z-values), then select this path and use the animations toolbar to create a flyby from path. When you do this, you should have your screen centered on the object you want to focus on. Right click on the object and select "Set ...

Perhaps one of these two methods will work for you: ArcMAP Select by Location 3D relationships and ArcScene Select by 3D Box How about Inside 3D (3D Analyst)? Since the output of Extrude Between is a feature class with multipatch 3D features, can you use this tool to identify the 3D Point features which are within the resulting soil horizons? Can you ...

You may want to look into LAStools, which can do a number of data conversions and basic visualizations of input LAS files, and conversions to both TIN and DEM. The same author also wrote a tool to visualize LIDAR data with Google Earth that may be of use.

As Craig says, OpenGL is the way to go for 3D. See Creating an ArcGIS Engine Application With C-Sharp and OpenGL. Earlier versions of ArcGIS Explorer also supported OpenGL calls, but last time I checked Esri no longer supports it. I don't know why they did this - OpenGL drawing really helped differentiate AGX from Google Earth. Update Even if your ...

Since for feature renderers, it is the property page that is registered so that it appears in the UI (renderers themselves are not registered), your best bet is to implement your own property page and relay all (or most) of its calls to an GraduatedColorPropertyPage instance. This class is the property page for class breaks renderers. Now, for the feature ...

How did you drape the vectors? I think you need to set the Base Heights. To do so: Right click the vector data layer and select Properties. Click the Base Heights tab. Select the radial button beside Obtain heights for layer from surface. The program automatically selects the DEM open in ArcScene. Click Apply, then move to the Extrusion tab. ...

I would use this approach: Add flood deep to DTM to create a new surface raster (use Plus (3D Analyst) tool). Drape the flood raster to the new surface.

I had the same problem using some SRTM DEMs. Besides from using some later and more correct version or another data source, I'd recommend setting all values below some chosen threshold (that will only select the hole pixels) to NoData (=erase them) and then re-interpolating them according to the surrounding pixels so that there will at least be no excesses.

It is amazing tool, it works in ArcScene 10.2 just follow this link http://wolfmapper.wordpress.com/2012/09/10/creating-feature-labels-in-arcscene-10-1/

The uncompressed AVI output was quite jerky There's a very good chance this has nothing to do with the quality of the video itself but that it is uncompressed. Uncompressed video is very large and I'd guess your computer simply isn't capable of reading it from the drive fast enough to be able to render it properly. A simple 1280*720 requires about 530 ...

You'll need the Quicktime codecs. You can either download and install quicktime from Apple. Or if you don't want all the junk that Apple bundle together, there's the QuickTime Alternative - though there's no guaranteeing that ArcGIS will pick that up. (See also, very bottom of - ...

Unfortunately, ArcScene has not been opened up to ArcPy like ArcMap has. There is an ArcGIS Idea to have this functionality added to which you might like to add your name.

The link in Devdatta's comment partially addresses how to simply drape the vectors, but despite this you can still experience the issues the OP mentions. I believe (personal hypothesis) that the mismatch is due to the difference in triangulation between your vectors and the underlying TIN. You notice this especially with large polygons where the ...

You should rather clean or smooth the source point data than generate a TIN or raster and try to clean later. Using ArcGIS Note that LAS data handling has greatly improved in ArcGIS 10.2. If 10.2 (with 3D Analyst) is available to you, try the build-in functions: There is a tool called Locate Outliers (part of 3D Analyst) which works perfectly for removing ...

You need to use the DTM as the base height for your flood depth raster and calculate a new height by adding the flood depths raster value to the dtm base height as a vertical offset. bearing in mind that water is flat (waves aside), you could also use a flat plane and calculate the flood limits as a height above sea level and set the height of the plane ...

ArcScene does not support vertex level editing for MultiPatch files, however ArcScene does not alert you to this fact. Source

I just had the same problem as you but had a different solution. In scene properties I changed the "Vertical Exaggeration" to "Geographic" (i know the question was asked a while ago but this offers another explanation. (Im using Arc Scene 10.1)
