Kuesa is a module for Qt 3D which provides:
- Support for glTF 2 importing
- Helpers for accessing and manipulating loaded content
- Custom PBR material
- Custom forward renderer for adding effects
- A Qt Creator template for quickly creating new Kuesa based projects
Note: this repository requires git-lfs support.
Kuesa requires Qt 3D 5.12.0 or later.
Kuesa can optionnally use the Draco mesh compression library, either through an embedded version, or a version present on the system. Draco can be used to dramatically decrease the size of glTF files.
Kuesa supports the KHR_draco_mesh_compression glTF extension as defined here:
https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_draco_mesh_compression/
By default, Kuesa will build with its own embedded version of the Draco library. This can be enforced with:
qmake kuesa.pro -- --draco=qt
To build Kuesa without any support for Draco, run qmake like this:
qmake kuesa.pro -- --draco=no
To build Kuesa with an external version of Draco, run qmake like this:
qmake kuesa.pro -- --draco=system
If Draco is not installed in the default location on your system, you can
set the DRACOSDK environment variable to point to where Draco is installed.
Use the DRACOSDK_LIBS environment variable to point to the folder containing
the Draco libraries.
Note that Kuesa has last been tested with Draco at commit 8833cf878e6fd43c5a3fd6e4231212e25e25e632.
The asset pipeline editor, provided with Kuesa, is able to compress existing glTF 2.0 assets with Draco.
Kuesa is composed of:
- A Qt module with core classes
- A QML plugin
- The assetpipelineeditor tool to preview and process glTF 2.0 files
- The cubemaptooctahedralmap tool to convert cube maps to octahedral maps to enable PBR rendering on ES 2 platforms
Kuesa builds as a Qt module and will be installed alongside Qt.
qmake
make
make install
Should examples not be built, try:
make sub-examples
cd examples
make install
To install the Qt Creator template, copy the entire kuesa folder
from tools/qtc_templates to the templates/wizards folder inside
the Qt Creator install location.
