Based on advanced timeline programming, e:cue SYMPHOLIGHT combines easy fixture and project set-up, content creation, automation and execution control in a single application. With powerful scripting capabilities, visual automation tools, and remote control via any web browser, e:cue SYMPHOLIGHT provides easy and playful design experiences even for the most sophisticated lighting and media applications.


The main challenge of this project was to realize DirectX 9-support and improved performance. Our old solution was written in C++ using the DirectX 10 feature “instancing”. This worked very well on newer machines, but not on older PCs or virtual machines. With the requirement of being able to run in virtualized environments, e.g. for the QA department, or Mac users, we have to support DirectX 9. On top we wanted to increase the performance, too.


After the first iteration of our implementation, we have achieved a performance increase of approximately 200%. In addition, the software can now run on virtual machines and older computers.

To do this, we reduced the number of vertices used by our scene by almost 99% by introducing new custom shaders. For our second iteration, we enabled the WaveEngine’s Batching functionality, which resulted in an almost unbelievable performance gain of 2700%.
