Project File and Objects Emulate Windows XP/2000 Folder and Icons

• Find a Project File in any directory as a folder icon.

• Open, close, resize, move Project File folder as any Microsoft folder or window.

• TNT objects appear as icons in this window.

• TNT folders appear as folders in this window.

• View folder contents in 5 Windows modes: Icons, List, Thumbnails, Tiles, and Details.

• Select TNT object icon with left mouse button to open a TNT products and view it
  (i.e., if Project File’s *.rvc extension registered as application for the TNT products).

• Select TNT group or layout icon with left mouse button to view that group or layout
  (i.e., builds view of the entire map from all the objects defined by the group or layout)

• Use right mouse button on object’s icon to open pop-up menu choices such as:

  • “Get Info” on a folder or object to view system-level details and thumbnail view,

  • “Open With” to browse to a particular TNT products to view the object,

  • Add object as a layer to any open view window,

  • Open the object in TNT display or edit mode,

  • View object properties (i.e., metadata accessed by “Info” icon in Project File Maintenance),

  • Browse into subobjects (i.e., masks, tiers, histograms, styles) and view details,

  • Delete or rename an object,

  • Drag object to another Project File folder, and so on.

Integration with Existing Selection Methods

• Use any of the other methods to open the TNT products and then select the object(s).

• Opening via an icon still opens all advanced layer control dialogs and edit tools.

• Add an object via its icon to a composite view opened by any available method.

• Use any object opened/added from the icon just as before
  (i.e., this is just another method of viewing or editing objects).

Auto-Open other TNT Supported Geodata Formats

• Select the geodata file’s icon with left mouse button to open it in a TNT spatial display
  (i.e., behaves like any other registered file type in Mac OS X and Windows).

• Use right mouse button to “Open With” TNT if file extension registered to some other products.

• Automatically uses TNT link file with pyramids, styles, … if available.

• Automatically makes TNT link file if none is available.

• Use pop-in dialog to optionally add TNT data not automatically provided by the format
  (e.g., add pyramids, specify CRS, …).

• Use as new alternate, but integrated, object selection procedure to start a TNT products
  (i.e., after selection in this fashion, this is just another TNT object in the view).

TNTatlas

• Use method familiar to Windows/Mac user to start from any supported geodata icon.

• Use method familiar to Windows user to start from any TNT object, group, or map layout.

• Fast use of all supported formats and objects regardless of size
  (e.g., huge JP2 or MrSID images, large shapefiles, …).

• Fast subsequent viewing of other geodata formats after first use
  (i.e., poor or inefficient design of other formats resolved when TNT link file automatically built for first use of any supported file, e.g., builds and saves pyramid layers, indexes ...).

• Provides a suite of built-in interactive tools: measurement, selection, region analysis, ...

• Automatically highlights the element(s) providing the contents of the DataTip
  (e.g., show polygon in its color style using solid or transparent fill or boundary only).

• User interface can be customized to focus on a specific use.

• Add interactive analysis tools via SML: Tool Scripts, selection dialogs, web URL access, …

• Easy installation program available for Mac OS X or autostart or install for Windows. 

New Direct Use Geodata Formats

• DWG files from AutoCAD 2005 and earlier versions (*.dwg).

• DXF files from AutoCAD 2005 and earlier versions (*.dxf).

• DGN files from MicroStation V8 and earlier versions (*.dgn).

• SID files from MrSID (*.sid) with LINUX.

• Access database now has its table relationships (i.e., schema) available. 

2D Display

Caching Individual Layers

• Separate memory buffer for each raster or geometric layer in 2D view.

• Each buffer is 32-bit (RGBalpha).

• Uses 8-bit alpha component in buffer for transparency and other effects.

• Buffer covers only portion of layer in view to conserve memory.

Use of Layer Caching

• Instantly toggle on/off any layer(s) in a view even if they are part of a group or layout.

• Add new layer draws only that layer.

• Direct selection of new element in view instantly removes previous element’s highlight.

• Elements used in DataTip instantly highlight (this is called a mouseover event).

• Highlight DataTip polygon elements in color as solid fill or boundary only. 

• Toggles View-in-View tool instantly.

Miscellaneous

• Toggle on/off duplicate styles in LegendView and multi-object legends.

• Point symbols can now be transparent.

• Improved intersection of styled lines using multipass rendering.

• Select/deselect all styles in list at once for copying. 

• Select form of label for UTM map grid to be xXX or xXXN (N = North or other direction).

3D Display

Layer Controls

• Use same powerful LegendView and controls as in 2D views.

• View legends for elements in each layer.

• Add, hide, and control individual layers as in 2D views.

• DataTips are shown for elements in 2D layers.

• All layers (objects) are rendered separately.
  Geometric elements no longer rendered into the surface drape layer
  (i.e., resolution of elements no longer set by large foreground image cells). 
  Faster to toggle on and off.
  Operation, features, and control closely parallel a 2D view.

Geometric Layers

• Improved perspective properties of all element types.
  Rendered as screen pixel independently of large surface cells in foreground.
  Improved appearance at vanishing point in background areas.
  Forced to stay on surface so portions do not disappear below surface.

• Render 2D elements draped on surface with more styles. 
  All element types conform to the surface shape.
  Point symbol rendered with all style elements including new transparency.
  Lines rendered as solid or transparent with all patterns. 
  Fill polygons with solid, transparent, hatch, and bitmap styles.
  Draw polygons “partially filled” using wide border, which draws only inward from boundary
  (why? complete filling even with transparency can obscure surface detail).
  CartoScripts are evaluated from attributes just as in 2D renderings.

• Render 3D elements as 3D shapes. 
  Points can be rendered as shaded color spheres and cubes.
  Lines can be rendered as shaded color pipes.
  Dashed lines rendered as pipes and spheres.
  Elements can be rendered at any XYZ position in the 3D view space.
  Elements with Z = surface elevation are intersected by surface.

Rendering Engine

• Error tolerance setting in variable triangulation controls quality versus speed.
  Lower setting provides maximum quality at average speed.
  Higher setting provides acceptable quality at faster speed.

• Variable Triangulation computations now buffered for faster redraws:
  When changing viewpoint parameters and
  To add, delete, or modify overlay layers.

TNTsim3D

Manifold Surfaces

• Include manifold surface(s) in a landscape file using Landscape Builder.

• View manifold surface(s) in a simulation
  (e.g., cross-sections, planar/curving profiles of any orientation, and outlines of 3D volumes).

• Smooth the path of the recording of a simulation and save it.
  Splines the recorded observer position path in 3D.
  Alters axis of Main view smoothly based upon recent, previous positions of observer.

Movies

• Create movie of the simulation in Main view from the recorded path using SML script.
  Script requests creation of, and access to, each frame of simulation.
  Script can be altered to modify the contents of each frame.
  (e.g., to insert something into each frame such as a logo, a sprite, …)

• Choose MPEG or AVI format and set the compression level for the AVI file.

Stereo

• Choose Main view of simulation to be stereo (i.e., 2 views from 2 viewpoints are created).

• Select method from side-by-side, line interleaved, column interleaved, anaglyph, or Sharp.

Help Dialogs

• Create text objects and add them to the Landscape File.

• Select and view text objects during simulation using Help menu.
  Use for instructions in any supported language.
  Provide metadata about author, geodata sources, description of landscape, …

Other System Level

Coordinate Reference Systems

• Improved viewing and analysis of “whole earth” objects.
  Reliably use objects crossing 180 degrees of longitude or including the poles.
  Use orthographic projection from any viewpoint.

• Use shorter, individual country CRS selection lists for easier access.

• Use MODIS image ellipsoid and datum.

• Add datum transformation from Indian 1954 to WGS84 for Thailand.

• Add Macedonia datum and State coordinate reference system.

• Add Stromlo CRS for Australian Capital Territory (ACT).

Miscellaneous

• Binary null masks used in more processes replacing null value 
  (why? using null value is meaningless in lossy compression as in MrSID and JPEG2000).

• Null masks are now very compressed using tile level compression.

• Improvements in speed of vector validation. 

• Improved accuracy of specified cell size when rendering to a raster object.

New Import/Export Process
