VTK Advanced Course

The advanced course builds upon the knowledge gained from the beginner course. It offers in-depth training on writing filters, composite data pipelines and advanced rendering approaches with VTK.

Objectives

• Learn about composite data structures
• Write a basic filter
• Create an advanced rendering
• Learn about parallel processing

Prerequisites

• Familiarity with VTK data structures
• Basic C++ programming knowledge
• Basic Python programming knowledge
• CMake knowledge a plus
• Familiarity with rendering approaches like ray tracing, a plus

Agenda

This course covers 8 hours of material, which can be divided into shorter sessions around your availability.

Our Recommendation: For onsite courses, we recommend either one 8-hour day of instruction (morning and afternoon sessions with a lunch break) or two 4-hour sessions on consecutive days. For an online course, we can accommodate a variety of schedules, including 2-hour sessions held on four consecutive days, or over the course of 2 or more weeks.
