The Roads Module offers the automatic generation of profiled roads and crossings from real-world navigation data (e.g. OpenStreetMap, Here). The input data is parameterized based on the vector data's shape and attributes and analysed automatically in a pre-calculation step. Thus complex road networks with various lane settings, crossings and markings are set up and created in no time.

The Roads Module contains various additional modifiers for the generation of roads. In the Profile modifier driving lanes, curbs or pavements can be defined along the road's profile. It is also possible to determine speed limits, markings or to add a camber in curves.

Crossings are generated automatically where lines with the Profile modifier intersect. Lines of arbitrary constellations may generate very complex crossings or also roundabouts. Different road types are thereby blended seamlessly into each other. Besides such junctions drive-ups are supported, that enables the generation of e.g. complex motorway interchanges. Transitions between different road settings e.g. 4 to 2 lanes are also created automatically.

Tunnels can be generated and cut into the terrain mesh with the accordant Tunnel modifier. The Bridge modifier offers the generation of generic bridges including pillars.

Roads Plus

The Roads Plus module offers additional features, so that traffic and driving simulations can make use of the visual database for their AI right away. The module contains the OpenDrive exporter, an open file format for logical description of road networks.

The included functionalities cover arc and clothoid based road generation. A clothoid represents a spiral that is placed before and after a curve's arc according to road construction rules. Existing vector data can be converted into such representations or new ones can be created by hand and later be edited. Those roads are cut into the terrain mesh with their height calculated from polynomials. With the Sign modifier signals like traffic signs and lights can logically be linked to roads or crossings.

Thus all preconditions for proper OpenDRIVE export of all AI information are met.



Meet us at the Driving Simulation & Virtual Reality Conference 2018 Europe

TrianGraphics will be showcasing the latest version of Trian3DBuilder at the 2018 edition of the DSC conference, held in Antibes (France), organized by the Driving Simulation Association. The goal of this international conference is to propose to academics and practitioners an all-round view of the state of the art of driving simulation technology, research and development. If you wish an in deep description of the talks offered at the Conference check out the DSC 2018 Program

We've just launched a new website for our terrain generation system Trian3DBuilder. Our product website has a new, fresh look, and provides a quick overview of our software's most important features. The clean design and intuitive navigation quickly directs you to the information you are looking for.

At you will find examples and case studies of our four main focus areas: ground, flight, automotive and maritime. Experience how simple and fast game quality terrain generation can be, by using Trian3DBuilder.


This new section in our website allows you to manage your licenses, dongle updates, installation files and download libraries in just a few clicks.

As an additional goodie, our Service & Support Customers will find the Trian3D Model Library XT completely free of charge in the installer section of the portal. The Trian3D Model Library XT contains almost 500 models with different LODs optimized for real-time rendering, a powerful resource for your 3D terrains.
