Photogrammetry

Photogrammetry Environment 3d Models & Textures

 

Photo scanning or Photogrammetry is a process that calculates the three-dimensional points of a surface using photo’s of a single physical real world object taken from different angles.

You take a large number of pictures of the object (generally at least 50-60 are needed, but for very high res objects hundreds of images may be needed) from all possible directions, then use these photos as an input for software that generates a 3d model. The software will look for features that are visible in multiple pictures and try to calculate from which point the picture was taken.

Knowing the camera positions and orientations, it creates a 3D point cloud that corresponds to the 2D details on the photo, think of a point cloud as millions of dots in 3d world space (X,Y,Z Possitions).

This point cloud can then be used to generate polygons connecting these dots together to create a surface skin that represents the object. Not only does it create the model but uses the photo’s to texture the 3d model creating a final photoreal version of that real world object in the computer.

 

The images shown above are just a few examples of the 3D models generated by us to be included in our terrain environment packs, The finished packs will include High Res models and lower poly count bakes ready for realtime environment usage.

Project included

Photography, Blender 3D, Meshroom Photogrametry software,

3D Model creations, including: 

  • Roads
  • Bollards
  • Telephone poles
  • Ground clutter
  • Tree stumps
  • Speed bumps
  • Mud banks
  • Rocks
  • Cliffs

All objects have been retopologised to include lower polygon versions and texture baked ready for realtime game environments engines like UE4, Unity etc.

CG Volcano’s Pack

CG Volcano’s Environment Pack 8K

 

This is a production quality high res asset pack, These terrain are suitible for Arch viz background mats, Full 3D environment’s with 16 bit height map, Normal map, Rock mask, Ambient occlusion, Flow map, Deposition map, Wear map, low level vegatation map, elevation specific bush mask, Scrub mask, angle based tree masks and snow mask.

Terrain in reality only has bush’s, tree’s growing at specific (feet) elevation levels, each vegetation and tree mask set abides by these rules based on extensive research on elevation based growth and natural evloutional survival. Certain trees would only grow at certain ground angles, certain tree’s would only grow in the shadow of more aggresive species. All maps provided are created on this natural law based system.

These mask maps can then be used to lay down particle system on the terrain so only specific 3d models are spawned in the correct real world possition.

 

The procedural approach developed for this project gives us the ability to terrain layer mask within engine and generate procedural foliage placement of trees, shrubs, rocks and all environmental assets by using a layer mask to place objects rather than manual user placement.

This means that generating massive terrain environments is possible, eliminating manual placement and configuration of elements within large scale environments which would bear near impossible at massive scale. Using our procedural approach we are able to develop Massive terrains in a fraction of the time.
