Topos R2 supports the work of design and environmental planning
professionals such as architects, landscape architects and
environmental engineers. Topos R2 is a software tool with
unique features and functionalities for three-dimensional (3D)
site design, visualization and experimentation. It enables users
to combine existing landscape, construction site or environment
features with envisioned changes. It provides a high degree of
flexibility, supporting on-the-fly change and experimentation with
An overview of the new features in Topos R2 is also available.
Real time interactive 3D visualization of large populated terrains.
Manipulate objects and terrains in real time while immersed in
the 3D world, using gestures, menus, property editors and
object browsers. In the image on the right a number of
wind turbine models are shown, with one of them selected.
Properties of the selected turbine model can be edited in the
property editor on the right. The object
browser on the left provides a tree-view of the workspaces
and models, and provides shortcuts to frequently used
Topos R2 supports loading 3DS, FBX and DXF 3D
models, as well as GIS data in ESRI shape file format
and MapInfo MIF/MID format.
Interchange geo-referenced positions directly with other programmes
like Excel or PLS-CADD via copy-paste, or use GIS files or CSV files.
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
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.
Routes and flythroughs.
Create realistic impressions of
walking, driving or flying routes through an intuitive
point-and-click interface for creation of key viewpoints and
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
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.
Generation of ZVIs and viewsheds.
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.
Power line modeling.
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.
Output very high resolution screenshots,
plan views and panoramas.
Topos R2 can generate various types of panoramas that can be used as
input for photomontages.
Load GIS layers from industry standard
formats such as ESRI Shape files and MapInfo MIF/MID files. Areas
defined by GIS data can be extruded above the terrain,
eg. to raise forest areas.
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.
Areas defined by GIS data can be imprinted onto a terrain drape.
Notice the 2D overview overlay in lower right corner,
showing your current position, as well as positions of selected
Simple creation of terrains from DTMs and drapes.
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
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.
Work from multiple angles at once by having
several windows open with independent viewpoints.
Apply atmospheric effects like fog, sun light, or clouds to create more realism.
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
Smooth interaction and presentations through innovative
features like gesture recognition, tool halos, drag
and drop, semi-transparent toolbars, spatial
parsing, a magnifier tool, etc.
Drag and drop ordinary documents into workspaces.
Notice how the turbines cast animated shadows on the
Free hand sketches can be drawn on top of documents, in
several layers and colors, to highlight changes or mark
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.
Trees and forests.
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.
Topos R2 uses the OpenGL API to realize its real-time 3D interface.
