In this work we present a visualization system for particle collisions in high-
energy physics, which we developed in cooperation with CERN. During the
experiments in particle physics a large amount of data is acquired, used
for event reconstruction. For better understanding suitable visualization is
needed. This poses a big challenge due to large amount of data, especially
when we want to achieve real-time interactive functionality.
For wider accessibility we decided to implement the visualization in web-
based technologies. We developed a visualization system using WebGL, op-
timized for fast and efficient use with GPUs. We focused on minimization
of draw calls and minimization of data transfer to the the GPU. This proofs
as an efficient solution confirmed by performance analysis of the developed
The system was also tested using the Med3D system, which uses a hybrid
rendering mode. This combines rendering through a browser with rendering
on a dedicated server.
