The course will focus on visualization of large datasets that can come from simulations of different physical phenomena (e.g. fluid dynamics, structural analysis, etc.). To create visually pleasing outputs of such data a path tracing rendering method will be used. Most of the course aspects will be covered within the popular 3D creation suite Blender. We will work with the brand new version 2.8 and introduce our developed plug-in called Covise Nodes to work with the scientific data inside Blender. Within the course we will demonstrate some of the basics of Blender, followed by a data visualization example using the plug-in, and we will finish the course with rendering of the final scene on the Salomon cluster.

The course will be mainly hands-on.

Purpose of the course (benefits for the attendees)

Attendees will learn how to visualize different simulation data in Blender and how to provide visually pleasing outputs.

About the tutor(s)

Petr Strakoš obtained his Ph.D. from CTU (the Czech Technical University in Prague) in Mechanical Engineering. Now he is a member of the Infrastructure Research Lab and the VaVR (Visualization and Virtual Reality) group, where he focuses on research in the area of visualization, image processing, and efficient utilization of these topics on a cluster. He also cooperates with partners from industry and other institutions in applied research.

Milan Jaroš is a researcher in the Infrastructure Research Lab at IT4Innovations. He has nine years of experience in professional programming (C++, C#, Java, etc.). He has developed several pieces of commercial software (including mobile applications). In recent years he has been focusing on research in the area of HPC computing (including support of GPU and Intel Xeon Phi coprocessor), processing of medical images, and visualizations of engineering data (virtual reality, rendering, post-processing of CFD calculation, etc.). He is a co-developer of plugins for multiple pieces of software (Blender, COVISE/OpenCOVER, Unity, etc.).

Alena Ješko is a researcher in the Infrastructure Research Lab at IT4Innovations. She has worked on mesh transformation topics for cranial orthosis design and photogrammetry for treating orbital fractures. She has recently started to work on AI and Machine Learning in Image Processing.

Basic knowledge of Linux and its terminal.

Participants must bring their own laptops and mice. The best user experience with Blender is when using a full-size keyboard. Therefore, we will supply the attendees with keyboards.
NEW: Use the following link to download an appropriate version of Blender-Covise for your laptop. Install it before the course

Target audience

Software developers and researchers in HPC.
