System: The Golang-based application comprises core application GUI, which may be hosted separately, and is designed to operate in the low latency environment of a local network. Arbitrary event-driven show logic is supported via an internal scripting system. Rapidly changing data is cached externally (with Memcached) to prevent loss of state in the event the core application goes down.

Client: Technical Productions

Technologies: Golang, Echo, Javascript, MySQL, Memcached

Problem: A centralised piece of software is needed to coordinate sound, lighting and other IoT devices in interactive show venues.

Solution: Devices,  device commands, network setup, show "actions" and responses to events can all be defined by show operators to create arbitrary show scenarios. The software interfaces with popular software favoured for sound and lighting, and includes a versatile distributed dashboard scheme which allows custom dashboards to be created that can be hosted across multiple machines. 

System: Distributed web-automation application simplifying tasks on a public sector ecommerce portal

Client: MePATool

Technologies: Perl, Javascript, Mojolicious, Hypnotoad, SQL

Problem: The workflow required for public sector ecommerce in a particular jurisdiction can slow down business.

Solution: 7 subsystems have been created and are maintained by Virtual Blue, including client executables, API, Web Admin and web-automation processes. Multithreaded headless Chrome instances are controlled via a custom process management system. Rendering browsers tend to be memory hungry which is one reason the system is distributed across several servers, in order to cope with traffic spikes. Recently very low error rates have been achieved.

System: Web application to display an interactive 3D animation of a truck loading a specified shipment

Client: Private

Technologies: .NET core, C#, Blender, Three.js, SQL

Problem: Create a web application which loads details of a user-specified shipment from a database, and depicts that shipment loading in a user-interactive animation.

Solution: This project integrates a number of separate areas of software engineering, including web development, 3D modelling and dynamic animation. The truck trailer with backgrounds and skybox were modelled in Blender, together with the Cargo bay and truck door opening animations - and these were imported into Three.js. Camera zoom and rotation were enabled using OrbitControls.js. The cargo box loading animation was created in Three.js directly using suitable vector mathematics, and the system mounted in a .NET core based framework. Specification of the shipment to load is provided by the user via a web form.
