Perform On-the-fly modifications to the models while you explore it. Change the presentation of the terrain on the fly: change the drapes, toggle wire frame rendering and sihouette edges. Move and change the models on the fly as well.

Topos R2 provides high performance on large data sets through advanced dynamic level of detail algorithms and terrain slicing, taking advantage of modern graphics processors.

Assess the impact of light and shadows through hill-shading (optionally with self shadowing) and real-time display of animated shadows from 3D objects (e.g., animated wind turbines).

Render terrain silhouette edges to output "wireline" renditions.

Use the intuitive free-form navigation tools to explore the area and the impact of a new development.

Model rural as well as city developments.

Use large CAD models together with high resolution aerial photography and high resolution DTM data.

Investigate new city developments.

Create realistic impressions of walking, driving or flying routes through an intuitive point-and-click interface for creation of key viewpoints and paths.

Record flythroughs and free-form navigation to AVI video files that can be posted on a website or shown to clients.

Gain an understanding of important sequential and serial effects of a design on a landscape through drive-through and walk-through routes.

Interactively explore arbitrary viewpoints and routes with clients, consultees, and the public by being able to freely navigate and amend the model on a common laptop computer.

Assess the cumulative impact of multiple windfarms as Topos R2 supports a large number of 3D objects in the same model.

Topos R2 has built-in support for computing ZVI (Zone of Visual Influence, also known as ZTVs : Zone of Theoretical Visibility) maps and viewsheds. This can also be used for RADAR visibility computations.

Topos R2 takes advantage of multiple CPUs to generate ZVI/ZTV maps faster.

Topos R2 can also generate contour maps, hypsotint [NEW] maps slope maps, backcloth [NEW] maps, and skyline [NEW] maps.

Model overhead power lines with correct rendering of the cable curves (catenary curves) between pylons.

Arbitrary 3DS, FBX or DXF models can be used for the pylons. The cables are attached to the pylons by adding attachment point objects to the pylon model inside Topos R2.

You may also use accurate models of the insulators and see them swing properly on corner pylons as you move the powerline.

Understand the implications of changes through fast switching between different iterations of a design, using multiple nested sub-workspaces.

Topos R2 can generate various types of panoramas that can be used as input for photomontages.

GIS areas can also be used to make terrain modifiers that can dynamically alter the terrain.

Work in both local coordinates as well as in geo-referenced coordinates, like OSGB coordinates.

Notice the 2D overview overlay in lower right corner, showing your current position, as well as positions of selected view points.

Load DTM height data in a number of industry standard formats.

Directly integrate surveyor DTM data via LandXML.

Apply earth curvature to DTM data, and apply correction for atmospheric refraction.

Load and manipulate very high resolution drapes in a number of industry standard file formats.

Handle very high resolution (above 30,000 x 30,000 pixel) drapes, as Topos R2 loads drape tiles on demand.

Topos R2 supports geo-referencing of drapes to easily fit drapes to terrains.

Use a SkyDome to add animated clouds and vary how cloudy it is on the fly.

Set the angle of the Sun as a time and date. This influences the lighting of the workspace, the hill shading of the terrain, and shadows from objects.

Assess real time shadow flicker from animated wind turbines.

Smooth interaction and presentations through innovative features like gesture recognition, tool halos, drag and drop, semi-transparent toolbars, spatial parsing, a magnifier tool, etc.

Notice how the turbines cast animated shadows on the terrain.

Free hand sketches can be drawn on top of documents, in several layers and colors, to highlight changes or mark areas.

Free hand sketches and line drawings can be drawn on the terrains, and converted to GIS layers for later extrusion, filling etc.

Live updated snapshots of documents from 3rd-party applications (e.g. MS Word, Excel, AutoCad or PhotoShop) rendered inside the 3D environment.

Use simple bitmaps as models of objects like trees. Easily copy out large numbers objects for modeling e.g. forests.

Use GIS areas or sketches to define which areas to fill with tree models. Fill an area with a certain density of trees (or other models), statistically vary tree distribution, size, and color.

Design your own trees from scratch or based on photography.
