from
DeLorme, around $100 per U.S. state for 6 CDROMs or 1 DVD - consists of the normal USGS DRGs, optionally draped on rather low-resolution elevation
- you can only view one quad at a time, rather than flying seamlessly over the whole state
- appears to use Direct3D: "3D map view not supported on Windows NT"
- can network with GPS and PDA units
- related DeLorme product Topo USA® 4.0 ($70) does only non-realtime rendering, but adds some impressive capabilities such as rendering trees on the green areas of the DRGs
- suite of software, for Windows, including assembling scenes and a runtime engine
- pricing depends on application
- reads elevation from "all kinds of ASCII format", model from 3DS, images from TIFF/BMP/JPG
- the focus is on applications like engineering, architecture, civil defense, emergency management, impact studies
- they also distribute, for all Italian territory, Orthophoto, Aerials and DTM ready for use in the software
-
"3D
Worlds" from Italian company
GeoMind, spun off
from Infmedia in 2004 - their technology takes elevation, imagery and 3D models as input, and produces scenes which are viewed in Macromedia Shockwave
- primarily intended for service work, not as a product for sale
- an option exists to use server-side rendering (!) where the 3D frames are sent down as a series of JPEG images
- their shockwave demos exhibit smooth but awkward navigation: the lack
of speed control were somewhat frustrating, and strict "minimum height"
and prevention of window resizing felt very constraining
- update 2003: they have fixed gimble lock on mouse rotation, and minimum height now bounces rather than sticking, so navigation is better
- still they 'do not allow window resizing because the reallocation [..] can cause some problem on machines with less RAM.' which seems reasonable for low-end system support
- $20 Windows program
- as described on their Landscapes page, it can import some grid formats (Scenery Animator, VistaPro, 1-degree DEM and GTOPO30) and export to a traditional 3D modeller format (around 20 formats)
ArcView
with
3D Analyst- $1000 + $2500 from ESRI
- purchased it and did a detailed evaluation
- summary: many problems and limitations, not recommended for virtual terrain work
- the latest incarnation of this software, for the Arc 8.x product line, is called ArcGIS 3D Analyst, which consists primarily of an 3D application called ArcScene; surely much improved since the old 3D Analyst, it should be reviewed
- two products from Sjöland&Thyselius Virtual Reality Systems AB (STVRS) of Sweden
- Blueberry3D Terrain Editor ($quote) is a plugin for MultiGen-Paradigm's
Creator Terrain Studio,
which
can be used to add procedural detail to existing scenery, within the context
of standard FLT files- includes a map editor for designing terrain, reads ESRI binary/ASCII grids, DEM, DTED, SHP, GeoTIFF and many image formats
- Blueberry3D Development Environment ($quote) is a plugin for MultiGen-Paradigm's Vega Prime, which allows procedural detail to be created at runtime
- email them for price requests, "price will vary depending on location and distributor"
- previous features of the Blueberry3D project (see the Evaluation of Blueberry Realtime Viewer as of 2001) including realtime shadows and photorealistic movie rendering, were apparently dropped in 2002 in favor of working closer to Vis-sim standards
- Geoformer is €1000 from Bitmanagement Software GmbH, test version is a free download
- Reads most image and heightfield formats, writes terrain scenes to the special extended-X3D/VRML file format that is supported by their web plugin viewer BS Contact Geo

- this is the same program as MultiGen's SiteBuilder 3D (see below)
- high-end, around $10,000 from MultiGen (as of 2000)
- expensive terrain tools, once SGI-only, are now integrated into Creator, available for NT
- advantages
- creates an optimized triangulation (Delaunay) for each patch
- builds a regular quadtree, yet maintains edge coherence
- disadvantages
- can't join more than one source DEM
- at highest detail, it still doesn't use the raw data points
- artifacts are produced by their LOD edge coherence approach
- very expensive
Cruiser- suite of terrain visualization software, proprietary server and client, from Greek company Talent
- the client is Java-based and theoretically is portable, although as of June 2006 it was only available for Windows
- you don't buy the software, instead you hire them to assemble and host your content as a "channel", so the price can vary greatly depending on what you want to host
- the client has a typical 3D navigation interface, not unlike World Wind, etc.
- their demo content (only content existing as of June 2006) is Greece on-line, whose interactivity consists of the usual flight, toggling of layers, measuring distances, lightweight 2D features
EarthVision
- $? from Dynamic Graphics, Inc.
- for building 3D models of underground data; primarily used by the petroleum industry

- geographic data is preprocessed in GeoBuilder 2D, an ESRI ARC/INFO based tool
- aerial photographs and satellite images are processed with SOCET SET from GDE Systems
- EaSIEST (NT and Unix)
- seems to be combination of MultiGen's Creator 3D, Arc/Info GIS from ESRI, and PhotoShop
- seems to target a lower-end market than Integrator
- how these packages fit together is not entirely clear
-

- pricing isn't mentioned, presumably far less expensive than the planetarium hardware it's designed for
- works on single-display PC platforms, fisheye PC platforms and multichannel SGI and PC platforms.
vGeo
- Virtual Global Explorer and Observatory- from VRCO, high-end, Linux, Irix and Windows
- pricing is specific to each customer
- an "interactive data fusion and visual analysis tool" for general data visualization, which includes some terrain functionality
- supports primarily scientific data formats such as netCDF and HDF, but not common terrain formats such as DEM
- Microsoft's 3D terrain visualization software.
- It apparently does not have a website of its own, only exposed to users as a component inside the maps.live.com site.
- Only runs as an OCX inside Internet Explorer (not standalone, no other platforms or browsers).
- Content is static. No way to display your own data or turn features on/off as there is with Google Earth.
- Includes attractive 3D models of landmark buildings for 15 US cities (from Harris Corp's RealSite)

$2475
from 3D Nature, for Windows, dongle-protected - non-realtime terrain rendering package, more fully-featured version of World Construction Set (see Artificial Terrain page)
- adds a very large number of features, including support for diverse projections, georeferenced imagery, queries to feature databases, randomizing of objects, procedural generation of walls and simple buildings, OpenGL preview, irregularly shaped terrain, more
- 3DNWorld is a user's community site for users of WCS and VNS to exchange components, share tutorials and show off their work - some is artwork and fantasy, but an increasing amount is accurate, non-realtime terrain visualization!
- they have a useful page of Sources for DEM and Vector Data
VWorldTerrain- expensive (starting at $50k to license) proprietary terrain engine with a huge list of features
- paging of elevation/imagery databases, landscape terraforming (deserts, rain forests, mountains, etc.) with local vegetation, variable weather conditions (wind, temperature, snow, rain, mist, sandstorms, etc.) and advancing time (dawn, daylight, dusk, night), autonomous animals and vehicles, blended procedural textures, extrusion of buildings for rapid urban scenes, and much more
- this is the engine used in the Eingana edutainment title (2000-2002, see Tourism page) which has continued development since that time
- WorldPerfect ($13000) generates scenes and VRSG ($5000) provide the runtime and SDK
- from MetaVR, Inc.
- expensive tools which appear to be mostly oriented toward military customers
- claims to support massive data such as large areas at 1m resolution
- add-on tools for interfacing with maps ($7000) only mentions military map formats
