Feature Highlight: Vertex shifting for SoHeightFieldRender

02 Feb 2021

Height field rendering is a powerful feature implemented for efficiently rendering large “horizon” surfaces in E&P seismic interpretation applications.  The height field representation is memory efficient and stored as a multi-resolution hierarchy (like volume data) to maintain interactive rendering even with many horizons.  By definition, height values are stored on an implicit regular grid.  Open Inventor Toolkit 10.8 introduces a shader function that allows the application to shift the grid vertices on the GPU with no performance penalty.
