Simplygon is a tool that optimizes 3D assets by reducing polygon counts and file sizes while maintaining visual quality. It works by converting 3D files between different formats and simplifying geometry through processes like remeshing and aggregation. Users upload source assets, Simplygon processes them according to defined settings, and optimized assets can then be downloaded and used in games, apps, and other platforms.

7. Transcoding is converting from one file
format to another
In some cases, this is a very complicated and
sensitive process

8. Simplygon can digest
JT, Step, FBX, Obj, STL, GLTF, GLB
Simplygon can transcode to
FBX, Obj, STL, GLTF, GLB, SSF

19. How do you put a Photoshop PSD-
file on the web or on a mobile
device?
You convert it to a JPEG
You lose depth and some quality,
but you gain compatibility and
reduce size
About Optimization

20. Simplygon is the “JPEG of 3D”
Sacrifice depth for compatibility and
performance
Visual quality loss minimized as much
as possible

23. The core of Simplygon optimization is a
set of “processors”
You don’t use the core directly
Simplygon Cloud exposes Simplygon as a
REST API

Using Simplygon

24. Simplygon – common operations
 Reduction
 Reduce the number of triangles in a 3D geometry
 Remeshing
 Create a “proxy geometry” that is visually similar but structurally completely
different from the source model
 Aggregation
 Combine many objects into a single object
 Material baking (used in conjunction with the above)
 Combine multiple materials into a single material, using textures to represent
material properties
 You specify your desired operation in a SPL-file.

25.  Control the behavior of the processors
with settings files
 SPL – Simplygon Processing Language

What it is - Recommendations

29. Recommended Use Cases
 A catalogue of “homogenous” and fairly simple assets
 Homogenous assets allows us to reuse the same SPL-file(s)
 “Outside-in” use cases
 Objects instead of environments
 Use Cases where triangle count is the major bottleneck
 Use Cases where only the exterior of the model is to be visualized
 Asset catalogues with standardized materials

30. Harder Use Cases
 Environments (architecture etc)
 Assets that can’t use a single SPL-file for the entire asset
 Assets with configurability needs
 Assets with highly complex materials
 Assets with problematic geometry (flipped faces etc.)
Doable, but requires deeper knowledge and effort
