Terrain
Builder Train3d builder

Trian3D Builder, the database generation system of TrianGraphics GmbH, is an innovative software system for generating virtual terrains.

Based on our project experience and novel concepts, we developed a tool which improves your workflow considerably. Trian3D Builder enables you to create large-scale detailed areas for your realtime applications based on image, height and vector data in hours.

Apart from high-quality geospecific databases geotypic and generic terrains are also supported. The data is optimized for realtime rendering and saved in various standard formats. Using vector data the software enables you for instance to place objects, render streets to the texture or to insert rivers into the terrain mesh.

Features

Generation of various types of terrain :
- Geospecific terrain: based on satellite data and aerial images
- Geotypic terrain: based on landcover data
- Generic terrain: height and slope dependant texturing
- combination of these terrain types

Features of geotypic terrain generation:
- replacement of terrain classes with typical photorealistic textures
- structure preserving blending between terrain classes
- heterogeneous tiling in every terrain class
- object placement matching underlying texture

Definition of regions with various levels of detail:
- definition of high detail insets possible
- per terrain tile various attributes can be assigned
- LOD count with switch-distances,
mesh resolution, texture resolution
- Geotypic object placement

Comprehensive vector editing:
- Import, create and edit points, lines, areas and bezier lines
- extensive transformation tools
- assign generation attributes using libraries

Ease of use:
- standardised, configurable user interface
- fast access to libraries
- immediate visualisation of all data

Data management
- management of re-usable data in libraries
- texture, geometry and vector attributes
- definition of data sets e.g. for various seasons or regions
- definition of groups with several elements
- definition of landcover features
- texture, alpha mask and object placement
- generation attributes for vector data
- object placement, RenderToTexture and geometry inserts

Object placement
- various geometry integration
- copy, instance, extern reference
- rotation, scale and object closeness with variance
- collision testing

Geometry integration:
- cut objects, lines or areas into the terrain mes
- height adaption
- specific height
- dependant on relief
- river behaviour (continuous decline)
- average height
- border for smooth transition to environment

Comprehensive optimization:
- tiling and LOD switching of database
- novel polygon saving edge algorithm
- optimized scenegraph
- geometry simplification using TIN-algorithm
- texture sharing between objects
- compressed texture support
- definition of different texture and mesh resolutions for tiles
- size dependant LOD switching of objects
- paging supported

Verification of databases in internal 3D viewer:
- high peformance visualisation
- tree view of scenegraph
- adjustment of render parameters
- camera clipping, fog, lighting
- various cameras for individual navigation
- statistics
