KUESA™ 3D: Qt & Qt 3D Real-time Music Box

Embedded software specialist and Qt Service Partner, KDAB, is one organization that uses the Qt cross-development platform to deliver the rich, intuitive and multiscreen interface experiences demanded by today’s industrial users. On behalf of its customer, MIGARI IT - an engineering company specializing in high accuracy measurement systems for the automotive industry – KDAB recently developed a comprehensive software system for the management, monitoring and automation of precision industrial measurement systems.

The aim of the MIGARI project was to develop a highly configurable and robust application that would meet the requirements of modern software systems in the ‘Internet of Things’ age. The system can integrate a wide variety of measurement hardware and buses and is programmable and extensible by the integrator and end user. Engineered from the ground up with the needs of industrial users in mind, the system is based on Qt version 5.0 and uses QML as a domain-specific language to describe the layout of each machine setup as well as to describe measurement and analysis plans. QML is also used to adapt visualization screens dynamically to varying needs. The architecture allows for the visualization to be run on a separate device from the data acquisition and the system can run on any operating system platform that provides drivers for the connected hardware.

Migari Touch UI - a real world example of a machine front-end

This 3-part series shows how our designers work with KUESA 3D daily. The scene used as the example here is a traditional 3D cube over a simple plane with great looking metallic reflections and a cube reflection on the plane. It is done using only QML, 2D tricks and effects and KUESA Iro materials.

The first video focuses on the Blender side of the process: creating the scene, the objects and the materials we need for the QML implementation.

KUESA 3D Studio Designer Workflow - Part 2

Heaptrack is a fast heap memory profiler that runs on Linux. It allows you to track all heap memory allocations at run-time. Afterwards, the accompanying GUI tool can be used to find optimization opportunities in your code by analyzing the recorded profiling data.

Heaptrack traces all memory allocations and annotates these events with stack traces. Dedicated analysis tools then allow you to interpret the heap memory profile to:
- find hotspots that need to be optimized to reduce the memory footprint of your application
- find memory leaks, i.e. locations that allocate memory which is never deallocated
- find allocation hotspots, i.e. code locations that trigger a lot of memory allocation calls
- find temporary allocations, which are allocations that are directly followed by their deallocation
- measure differences in all of the above before and after changing the code

You can use heaptrack pretty much wherever you are using Linux – it has been successfully used on 32bit and 64bit flavors of x86 and ARM platforms, both on embedded projects as well as desktop applications.

You can download Heaptrack for free here: https://www.kdab.com/heaptrack-version-1-2-0-released/

About the tool's creator:
Milian Wolff created the Massif-Visualizer, Heaptrack and Hotspot tools now used widely to improve C++ and Qt applications performance. When not applying his knowledge to improving code base performance for KDAB’s customers, Milian maintains QtWebChannel for the Qt Project and is co-maintainer of the KDevelop IDE. In 2015, Milian won KDE’s Akademy Award for his work on Clang integration. Milian has a Masters Degree in Physics and lives in Berlin. He is fluent in English and German.
