Isogeometric Volume Visualization
Interactive Isogeometric Volume Visualization with Pixel-Accurate Geometry
A recent development, called isogeometric analysis, provides a unified approach for design, analysis and optimization of functional products in industry. Traditional volume rendering methods for inspecting the results from the numerical simulations can not be applied directly to isogeometric models. At SINTEF we developed a novel approach for interactive visualization of isogeometric analysis results, ensuring correct, i.e., pixel-accurate geometry of the volume including its bounding surfaces. The entire OpenGL pipeline is used in a multi-stage algorithm leveraging techniques from surface rendering, order-independent transparency and numerical theory of ordinary differential equations.
