Topics

Visualizing Volume Data
This example shows several methods for visualizing volume data in MATLAB®.
Overview of Volume Visualization
Volume visualization is the creation of graphical representations of data sets that are defined on three-dimensional grids.
可视化标量卷数据的技术
There are several techniques available for visualizing scalar volume data, such as MRI slices.
可视化四维数据
This example shows several techniques to visualize four dimensional (4-D) data in MATLAB®.
Visualizing Vector Volume Data
There are several techniques that are useful for visualizing vector data, such as stream lines, stream particles, stream ribbons, stream tubes, and cone plots.
Exploring Volumes with Slice Planes
A slice plane is a surface that takes on coloring based on the values of the volume data in the region where the slice is positioned.
Connecting Equal Values with Isosurfaces
Isosurfaces是通过在每个顶点处具有相同值的音量中的表面来构建的。等音图与轮廓图相似，因为它们都指示值等于的位置。
Isocaps Add Context to Visualizations
ISOCAPS是安装在等值面的范围的平面，以提供iSosurface的视觉上下文。
使用向量数据显示流线
Visualize air currents in 3-D using streamlines, slice planes, and contours on the same plot.
Displaying Curl with Stream Ribbons
Stream ribbons illustrate direction of flow, similar to stream lines, but can also show rotation about the flow axis by twisting the ribbon-shaped flow line.
显示与流管散度
Stream tubes are similar to stream lines, except the tubes have width, providing another dimension that you can use to represent information.
Create Stream Particle Animations
Visualize the speed and direction of particles within vector fields using streamlines.
Vector Field Displayed with Cone Plots
This example shows how to use cone plots, isosurfaces, lighting, and camera placement to visualize a vector field.
