Kuesa 3D 1.2 release!
Today, KDAB is releasing version 1.2 of the 3D integration workflow Kuesa 3D, built on top of Qt 3D. Kuesa™ 3D is a complete design-to-code workflow solution for 3D in real-time applications, centered around the open glTF™ 2 format, supported by Blender, Maya and 3ds Max. In short, Kuesa provides a workflow that simplifies work […]
Qt 3D: One too many threads or what has changed in 5.14
Qt 3D makes heavy use of threads, as a way to spread work across CPU cores and maximize throughput, but also to minimize the chances of blocking the main thread. Though nice on paper, the last case eventually leads to added complexity. Sometimes, there are just one too many threads. In the past, we’ve been […]
Python – Tron Demo Using Qt Quick and the Qt 3D QML API
For SIGGRAPH, KDAB has been working on a new Qt 3D based demo. We decided that instead of using C++, it would be interesting to try out PySide2 and harness Python to drive the application. The idea behind this demo is to do with data acquisition of a vehicle’s surrounding environment. Once the data is […]
Exporting 3D content for Qt 3D with Blender
At the heart of every 3D application is geometry. Qt 3D-based 3D applications are no different and require the user to either generate geometry or provide asset files for Qt 3D to load. This blog post demonstrates how Blender and its Python API could be used to write an exporter that generates geometry for Qt […]
Qt3D 2.0 The FrameGraph
Continuing our blog post series about the rewrite of Qt3D. Introduction For quite some time now, you’ve been hearing about Qt3D’s Framegraph. Although a brief definition of what the Framegraph is was given in the previous articles, this blog post will cover it in more detail. After reading this post, you will understand the difference […]
