volume

volume(volume_data)
volume(x, y, z, volume_data)

Plots a volume, with optional physical dimensions x, y, z. Available algorithms are:

• :iso => IsoValue

• :absorption => Absorption

• :mip => MaximumIntensityProjection

• :absorptionrgba => AbsorptionRGBA

• :additive => AdditiveRGBA

• :indexedabsorption => IndexedAbsorptionRGBA

Plot type

The plot type alias for the volume function is Volume.

Attributes

absorption = 1.0 — Absorption multiplier for algorithm=:absorption. This changes how much light each voxel absorbs.

algorithm = :mip — Sets the volume algorithm that is used.

alpha = 1.0 — The alpha value of the colormap or color attribute. Multiple alphas like in plot(alpha=0.2, color=(:red, 0.5), will get multiplied.

backlight = 0.0 — Sets a weight for secondary light calculation with inverted normals.

colormap = @inherit colormap :viridis — Sets the colormap that is sampled for numeric colors. PlotUtils.cgrad(...), Makie.Reverse(any_colormap) can be used as well, or any symbol from ColorBrewer or PlotUtils. To see all available color gradients, you can call Makie.available_gradients().

colorrange = automatic — The values representing the start and end points of colormap.

colorscale = identity — The color transform function. Can be any function, but only works well together with Colorbar for identity, log, log2, log10, sqrt, logit, Makie.pseudolog10 and Makie.Symlog10.

depth_shift = 0.0 — adjusts the depth value of a plot after all other transformations, i.e. in clip space, where 0 <= depth <= 1. This only applies to GLMakie and WGLMakie and can be used to adjust render order (like a tunable overdraw).

diffuse = 1.0 — Sets how strongly the red, green and blue channel react to diffuse (scattered) light.

enable_depth = true — Enables depth write for Volume, so that volume correctly occludes other objects.

fxaa = true — adjusts whether the plot is rendered with fxaa (anti-aliasing, GLMakie only).

highclip = automatic — The color for any value above the colorrange.

inspectable = true — sets whether this plot should be seen by DataInspector.

inspector_clear = automatic — Sets a callback function (inspector, plot) -> ... for cleaning up custom indicators in DataInspector.

inspector_hover = automatic — Sets a callback function (inspector, plot, index) -> ... which replaces the default show_data methods.

inspector_label = automatic — Sets a callback function (plot, index, position) -> string which replaces the default label generated by DataInspector.

interpolate = true — Sets whether the volume data should be sampled with interpolation.

isorange = 0.05 — Sets the target value for the IsoValue algorithm.

isovalue = 0.5 — Sets the range of values picked up by the IsoValue algorithm.

lowclip = automatic — The color for any value below the colorrange.

material = nothing — RPRMakie only attribute to set complex RadeonProRender materials. Warning, how to set an RPR material may change and other backends will ignore this attribute

model = automatic — Sets a model matrix for the plot. This overrides adjustments made with translate!, rotate! and scale!.

nan_color = :transparent — The color for NaN values.

overdraw = false — Controls if the plot will draw over other plots. This specifically means ignoring depth checks in GL backends

shading = automatic — Sets the lighting algorithm used. Options are NoShading (no lighting), FastShading (AmbientLight + PointLight) or MultiLightShading (Multiple lights, GLMakie only). Note that this does not affect RPRMakie.

shininess = 32.0 — Sets how sharp the reflection is.

space = :data — sets the transformation space for box encompassing the plot. See Makie.spaces() for possible inputs.

specular = 0.2 — Sets how strongly the object reflects light in the red, green and blue channels.

ssao = false — Adjusts whether the plot is rendered with ssao (screen space ambient occlusion). Note that this only makes sense in 3D plots and is only applicable with fxaa = true.

transformation = automatic — No docs available.

transparency = false — Adjusts how the plot deals with transparency. In GLMakie transparency = true results in using Order Independent Transparency.

visible = true — Controls whether the plot will be rendered or not.
