TRANSCAPES 02 - Research into 3D visualistions of GPS paths05 / 2007

Transcapes 02 was a first stage research project commissioned by Chris Bowman, Ian Gwilt, Gavin Perin and Steve Hatzellis of the Centre of Digital Design at the University of Technology, Sydney.

The project involved:

  • Investigation into 3D visualisation of GPS data from track points informed by the relationship between different points in time and space. Parameters such as time, location, distance and speed were looked at to explore connections between one or more paths.
  • The creation of the Transcape editor to upload and visualise GPS paths in various ways. ome of the visualisations that can be viewed dynamically through the editor are shown below.
  • Investigation and simulation of possible methods of visualising video content synchronistically with GPS content.

Future developments include the ability to export a file from the Transcape Editor to a format compatible with 3D modelling programs. This is to facilitate further manipulation in 3D programs and the development of physical 3D rapid prototypes created from the visualisations.

Visualisations of Paths in 3D

1. Default
Literal representation of path

2. Join Paths
Join points in two separate paths with splines across opposite time matched points.

3. Join Paths - Jacob’s Ladder
Joins points in two separate paths with splines across time matched points.

4. Jungle Gym
Poles from the ground up to points in conjuncton with the default connecting paths.

5. Multi-cast from Start
Lines are cast from the start point to every other point.

6. Multi-cast from Start & End
Lines are cast from the start point and end point to every other point.

7. Fat Geometry
Literal representation of path but extruded. In the next stage, the width would be directly related to speed, height or another parameter.

8. Extrude Over Time
Draws the elevation of points vertically over the duration of the path. Elevation is extruded from a points’ seconds from beginning of track.

9./10. Mesh Wall
Creates a mesh/wall of track from top to floor.

Visualisations of Paths and Video content in 3D

11. Video/path Synchronistic View 1
Default visualisation with video stills scaled relative to their distance from the viewer.

12. Video/path Synchronistic View 2
Multi-cast visualisation with video stills scaled relative to their distance from the viewer.

13. Video/path Synchronistic View 3
Mesh wall visualisation with video stills mapped to planes.
