# Visualisation de volumes

Représenter les données de volume maillées sous forme de diagrammes iso, slice et stream

Visualisez les données de volume et de champ vectoriel 3D. Par exemple, vous pouvez afficher les données de volume sous forme de tranches en 2D.

## Fonctions

développer tout

 `contourslice` Draw contours in volume slice planes `flow` Simple function of three variables `isocaps` Compute isosurface end-cap geometry `isocolors` Calculate isosurface and patch colors `isonormals` Compute normals of isosurface vertices `isosurface` Extract isosurface data from volume data `reducepatch` Reduce number of patch faces `reducevolume` Reduce number of elements in volume data set `shrinkfaces` Reduce size of patch faces `slice` Volume slice planes `smooth3` Smooth 3-D data `subvolume` Extract subset of volume data set `volumebounds` Coordinate and color limits for volume data
 `coneplot` Plot velocity vectors as cones in 3-D vector field `curl` Curl and angular velocity of vector field `divergence` Compute divergence of vector field `interpstreamspeed` Interpolate stream-line vertices from flow speed `stream2` Compute 2-D streamline data `stream3` Compute 3-D streamline data `streamline` Plot streamlines from 2-D or 3-D vector data `streamparticles` Plot stream particles `streamribbon` 3-D stream ribbon plot from vector volume data `streamslice` Plot streamlines in slice planes `streamtube` Create 3-D stream tube plot
