Knowra Scientific visualization Scientific visualization Scientific visualization uses visual representations to explore, analyze, and communicate scientific data and phenomena. It includes techniques for mapping measurements, simulations, and abstract structures into images.
Data visualization : The graphical representation of data to reveal patterns, comparisons, and relationships. Scientific visualization is a specialized practice within the broader work of representing data visually.
Medical imaging : The acquisition and analysis of images of the body for diagnosis, research, or treatment. CT and MRI data are commonly rendered to inspect anatomy and disease in three dimensions.
Scalar field : A function assigning a scalar value to every point in a space or region. Many scientific datasets encode quantities such as temperature or density as scalar fields.
Information visualization : The visual representation of abstract, nonspatial data to support understanding and analysis. It often handles relationships and categories rather than measured fields embedded in physical space.
Visual encoding : The mapping of data attributes to visual properties such as position, size, shape, or color. Encoding choices determine which patterns are salient and which comparisons are easy or misleading.
Volume rendering : A technique for displaying three-dimensional data by assigning visual properties to voxels throughout a volume. It reveals internal structures in medical scans and simulation datasets without first extracting surfaces.
Computational fluid dynamics : The numerical study of fluid motion and its interactions with surrounding forces and boundaries. Visualizations make simulated flows, vortices, and pressure fields easier to inspect.
Vector field : A function assigning a vector to every point in a space or region. Direction and magnitude fields require visual encodings such as arrows, streamlines, or glyphs.
Illustration : An image made to explain, depict, or embellish a subject, often through artistic interpretation. Illustrations may clarify scientific ideas without mapping data through a reproducible visual encoding.
Perceptual psychology : The study of how people perceive and interpret sensory information. Perception influences whether visual patterns and differences in scientific images are noticed accurately.
