Kuesa 3D for developers

Leverage powerful tools to preview, condition, sanity check and optimize assets

Developers have full control of the workflow. They can leverage all Kuesa 3D tools to preview, condition, sanity check and optimize assets. For example, the asset pipeline editor can help them preview and introspect the scene.


The Kuesa 3D engine is built using Vulkan and pure C++ and provides a drop-in solution to easily add high performance, seamless 3D to your application, with added features:

  • Imports glTF™ files, with specific Kuesa 3D extensions
  • Ability to load custom glTF materials
  • Supports PBR materials
  • Includes IRO Materials
  • Provides an optimized default frame graph (high level description of the OpenGL pipeline configuration)
  • Gives full access to the scene items via collections
  • Profiling capabilities
  • Animation extension, parse custom animation properties

Kuesa 3D easily integrates into any 3D or hybrid 2D / 3D Qt application. Developers are free to use either the C++ or the QML API and can access all the internals of the 3D scenes from the code - opening the way to all kinds of improvements ranging from adding special effects or user interactions to creating an optimized frame graph for a specific board. See more below.


Kuesa 3D is based on top of PBR (Physically Based Rendering) materials which approximate real world physics in real-time with a photo-realistic result. The materials used in the 3D design tool and the engine are the same, so the result will look alike in both applications.

IRO Materials

Physically-based rendering (PBR) can generate amazing images, but not all embedded systems have enough processing power to handle it. Also, without knowing the actual physics, PBR isn’t easily tweakable to simulate materials such as a pre-defined bitmap that needs to appear glossy. For these cases, or any other where PBR may be overkill, KUESA 3D supports the Iro Material Library. This library provides a catalog of materials that can simulate common surface properties (such as reflections, clear-coated paint, and transparency) and gives great looking results with less designer and GPU overhead. Iro Materials are 90% less complex than PBR materials and thus more performant and low risk when deploying on low end / embedded hardware.
