VIZBI 2011 brings together scientists actively using or developing computational visualization to study a diverse range of biological data.
Jeff Baumes and Wes Turner will be presenting a tutorial on Saturday March 19, 2011 from 10:00am – 1:00 pm covering VTK and ParaView.
This tutorial presents the fundamentals of VTK and ParaView, and describes how they can be used to construct visualization pipelines useful for biological research. VTK provides the ability to visualize and display anatomical and cellular data arising from medical imaging modalities. VTK has been used in diverse applications to view CT, MRI, PET and SPECT images, both as a collection of two dimensional slices in any of the axial, coronal, or sagittal views; or as volumetric or MIPS three dimensional displays. VTK is also suited to multidimensional data where each voxel of a volume may be composed from multiple values representing different modalities or e.g. different channels of data. In addition, VTK can look at large microscopy images, or movies of flow through a microscope stage. We will present the basics needed to write custom visualizations in VTK and how the ParaView application can view these data sources and perform large-scale visualization. In addition to visualizing geometry, images, and volumes, VTK is expanding its functionality to visualize data from ’omics fields, which includes pathways, charts, and dendrograms. We will present the current efforts in this area and how to use VTK to visualize various ’omics data.
