		| Abstract: | 
		The Theoretical Astrophysical Observatory (TAO) is a virtual laboratory that provides pipelines to build mock observations of galaxy survey data and other derived data products based on different cosmological dark matter simulations and semi-analytic galaxy formation models. We present recent work towards web-based interactive visual exploration of large datasets in TAO, using the high performance volume rendering technique Splotch - a ray-casting approach for visualising complex and multivariate large-scale point clouds.
 We outline how Splotch was adapted to accommodate specific TAO requirements and discuss work to expose functionalities through a web interface giving non technical TAO users the possibility to deploy Splotch in an HPC environment for easy access to state-of-the-art simulated data for a wide user base of astronomers. |
