meshscatter

meshscatter(positions)
meshscatter(x, y)
meshscatter(x, y, z)

Plots a mesh for each element in (x, y, z), (x, y), or positions (similar to scatter). markersize is a scaling applied to the primitive passed as marker.

Attributes

Generic

  • visible::Bool = true sets whether the plot will be rendered or not.

  • overdraw::Bool = false sets whether the plot will draw over other plots. This specifically means ignoring depth checks in GL backends.

  • transparency::Bool = false adjusts how the plot deals with transparency. In GLMakie transparency = true results in using Order Independent Transparency.

  • fxaa::Bool = true adjusts whether the plot is rendered with fxaa (anti-aliasing).

  • inspectable::Bool = true sets whether this plot should be seen by DataInspector.

  • depth_shift::Float32 = 0f0 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).

  • model::Makie.Mat4f sets a model matrix for the plot. This replaces adjustments made with translate!, rotate! and scale!.

  • color sets the color of the plot. It can be given as a named color Symbol or a Colors.Colorant. Transparency can be included either directly as an alpha value in the Colorant or as an additional float in a tuple (color, alpha). The color can also be set for each scattered mesh by passing a Vector of colors or be used to index the colormap by passing a Real number or Vector{<: Real}.

  • colormap::Union{Symbol, Vector{<:Colorant}} = :viridis sets the colormap that is sampled for numeric colors.

  • colorrange::Tuple{<:Real, <:Real} sets the values representing the start and end points of colormap.

  • nan_color::Union{Symbol, <:Colorant} = RGBAf(0,0,0,0) sets a replacement color for color = NaN.

  • space::Symbol = :data sets the transformation space for the positions of meshes. See Makie.spaces() for possible inputs.

Generic 3D

  • shading = true enables lighting.

  • diffuse::Vec3f = Vec3f(0.4) sets how strongly the red, green and blue channel react to diffuse (scattered) light.

  • specular::Vec3f = Vec3f(0.2) sets how strongly the object reflects light in the red, green and blue channels.

  • shininess::Real = 32.0 sets how sharp the reflection is.

  • ssao::Bool = 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.

Other

  • cycle::Vector{Symbol} = [:color] sets which attributes to cycle when creating multiple plots.

  • marker::Union{Symbol, GeometryBasics.GeometryPrimitive, GeometryBasics.Mesh} sets the scattered mesh.

  • markersize::Union{<:Real, Vec3f} = 0.1 sets the scale of the mesh. This can be given as a Vector to apply to each scattered mesh individually.

  • rotations::Union{Real, Vec3f, Quaternion} = 0 sets the rotation of the mesh. A numeric rotation is around the z-axis, a Vec3f causes the mesh to rotate such that the the z-axis is now that vector, and a quaternion describes a general rotation. This can be given as a Vector to apply to each scattered mesh individually.

Examples

using GLMakie

xs = cos.(1:0.5:20)
ys = sin.(1:0.5:20)
zs = LinRange(0, 3, length(xs))

meshscatter(xs, ys, zs, markersize = 0.1, color = zs)
