Kuesa™ 3D glTF2 Library

a glTF™ 2.0 importer for Qt 3D

Currently Kuesa 3D is the only way to properly use glTF with Qt 3D and is mostly glTF2.0 compliant. Building a full 3D engine on top of Qt3D involves the non-trivial effort of turning 3D assets into a smoothly running and bug-free application. Kuesa 3D glTF2 Library solves this problem by converting glTF2.0 files into Qt 3D assets.


All main 3D hosts like Blender, 3DS Max and Maya have a glTF2.0 exporter. A glTF2.0 file can be loaded into Kuesa 3D glTF2 Library as easily as loading a JPEG. Examples of glTF2.0 features supported are: skinned animations, PBR material, unlit material, compressed meshes and light extension.


Kuesa 3D glTF2 Library Features

Under the hood, when you load a glTF2.0 file into Kuesa 3D glTF2, collections of Qt3D elements are created automatically (e.g. entities, materials, etc). You can then retrieve and bind those objects of your 3D scene just like other QML elements. Also, you can either make 3D part of your UI, or better still, make 3D content created in Blender, 3DS Max part of your UI.

More Advantages

  • Artists can work separately from developers– the artist doesn't need the build environment of the developer
  • You can create complex interactive 3D apps easily on Desktop / ES3 out of the box ... even with complex features like the PBR material
  • You can apply post-processing effects: e.g. depth of field, bloom, blur, alpha masks, gamma correction, tone mapping
  • A pre-made frame graph is included for your convenience so that you can use Kuesa 3D glTF2 Library straight out of the box
  • Documentation and Examples included
