3D Model Guide

EYEVIEW^_® is currently optimised to display simplified 3D conceptual block models

EYEVIEW^_® 3D Model Guidelines

• App only recognises 3D models in our proprietary .elv file format
• App does not display texture maps
• App will not open if 3D models are too large

3D Modelling Instructions

• 3D model units must be metres
• 3D models must be geolocated to Great Britain Ordnance Survey National Grid coordinate system
• Device's GPS is used to locate the 3D models relative to Ordnance Survey National Grid coordinate system - Eastings, Northings and altitude AOD
• 3D model format is .OBJ
• Maximum 3D model budget:
  • Total combined polygon count of all 3D models: up to 4,000 polygons (faces)
  • Total combined file size of all .OBJ files: 400 - 600KB
• Ensure 3D geometry is simple and clean:
  • Construct building models from simple extruded surfaces, blocks or cylinders
  • Use triangles and quads polygons
  • Use as few sides as possible on circle and cylinder objects
  • Remove unnecessary or hidden caps and faces
  • Use single sided objects
  • No Boolean meshes
  • No coplanar/coincident faces that occupy the same space
  • It is acceptable to have intersecting faces that cut through one another
  • No isolated vertices
  • Weld vertices to avoid 'Rats Nest' errors
  • Normals must be unified and face outwards 
• Add a UVW box modifier to every object

Export Instructions

• Export 3D models as .OBJ files
• Use Export Selected procedure
• Export separate 3D models for the surrounding site and each individual proposed building design option 3D model
• Name exported .OBJ files logically to identify in which order you would like the design option models displayed in EYEVIEW
• A 'Rats Nest' error signifies one of the issues mentioned in the 3D Model Guidelines above exists in a 3D model

Email 3D models to EYELEVEL Creative using the link opposite

Email the following

• .OBJ file of surrounding site 3D model
• .OBJ file of each individual proposed building design option 3D model
• Each associated .MTL file
