The Red Dragon / Y Ddraig Goch

The Red Dragon / Y Ddraig Goch, is the famous emblem of Wales and appears on the national flag. On the occasion of the first ever visit of the Eurographics conference to this country we were pleased to release this high resolution 3D mesh of the Welsh Dragon into the public domain for use in your research. If used, please acknowledge “The Welsh Dragon mesh model was released by Bangor University, UK, for Eurographics 2011”.

The original model (lower left) was scanned using a Perception V5 Laser scanner mounted in an Infinite Portable Measuring Arm. This combination supports:

  • Rotation of the scanning arm through seven principal axes allowing access to difficult-to-reach details
  • Data cloud cloud collection at 458,000 points per second.
  • Laser bandwidth of 150mm
  • Acuracy of +/- 0.024mm
  • The scanning was carried out by CAM Innovation Centre(), at Coleg Menai, in Bangor Wales.

The point cloud has been transformed into the STL File format, and the Stanford Polygon File format for your convenience. The mesh contains:

  • 1,105,352 vertices
  • 2,210,673 faces
