# SliceDensityPlot3D

SliceDensityPlot3D[f,surf,{x,xmin,xmax},{y,ymin,ymax},{z,zmin,zmax}]

generates a density plot of f over the slice surface surf as a function of x, y, and z.

SliceDensityPlot3D[f,surf,{x,y,z}reg]

restricts the surface to be within region reg.

SliceDensityPlot3D[f,{surf1,surf2,},]

generates density plots over several slices.

# Details and Options    • SliceDensityPlot3D plots a function defined over a 3D region by using surfaces to slice the region, and colors the slices according to the values of the function.
• The following basic slice surfaces surfi can be given:
•  Automatic automatically determine slice surfaces "CenterPlanes" coordinate planes through the center "BackPlanes" coordinate planes at the back of the plot "XStackedPlanes" coordinate planes stacked along axis "YStackedPlanes" coordinate planes stacked along axis "ZStackedPlanes" coordinate planes stacked along axis "DiagonalStackedPlanes" planes stacked diagonally "CenterSphere" a sphere in the center "CenterCutSphere" a sphere with a cutout wedge "CenterCutBox" a box with a cutout octant
• SliceDensityPlot3D[f,{x,xmin,xmax},] is equivalent to SliceDensityPlot3D[f,Automatic,{x,xmin,xmax},] etc.
• The following parametrizations can be used for basic slice surfaces:
•  {"XStackedPlanes",n}, generate n equally spaced planes {"XStackedPlanes",{x1,x2,…}} generate planes for x=xi {"CenterCutSphere",ϕopen} cut angle ϕopen facing the view point {"CenterCutSphere",ϕopen,ϕcenter} cut angle ϕopen with center angle ϕcenter in plane
• "YStackedPlanes", "ZStackedPlanes" follow the specifications for "XStackedPlanes", with additional features shown in the scope examples.
• The following general slice surfaces surfi can be used:
•  expr0 implicit equation in x, y, and z, e.g. x y z-10 surfaceregion a two-dimensional region in 3D, e.g. Hyperplane volumeregion a three-dimensional region in 3D where surfi is taken as the boundary surface, e.g. Cuboid
• The following wrappers can be used for slice surfaces surfi:
•  Annotation[surf,label] provide an annotation Button[surf,action] define an action to execute when the surface is clicked EventHandler[surf,…] define a general event handler for the surface Hyperlink[surf,uri] make the surface act as a hyperlink PopupWindow[surf,cont] attach a popup window to the surface StatusArea[surf,label] display in status area when the surface is moused over Tooltip[surf,label] attach an arbitrary tooltip to the surface
• SliceDensityPlot3D has the same options as Graphics3D, with the following additions and changes:
•  Axes True whether to draw axes BoundaryStyle Automatic how to style surface boundaries BoxRatios {1,1,1} bounding 3D box ratios ClippingStyle None how to draw values clipped by PlotRange ColorFunction Automatic how to color the plot ColorFunctionScaling True whether to scale the arguments to ColorFunction PerformanceGoal \$PerformanceGoal aspects of performance to optimize PlotLegends None legends for color gradients PlotPoints Automatic initial number of samples for the function f and slice surfaces surfi in each direction PlotRange {Full,Full,Full,Automatic} range of f or other values to include PlotTheme \$PlotTheme overall theme for the plot RegionFunction (True&) how to determine whether a point should be included TargetUnits Automatic desired units to use WorkingPrecision MachinePrecision the precision used in internal computations
• ColorFunction is by default supplied with the scaled value of f.
• RegionFunction is by default supplied with x, y, z and f.
