WebGL rotating F: Difference between revisions

=={{header|Julia}}==

Makie can use OpenGL as a backend for plotting (GLMakie). The code plots an 'F' as three rectangular solid-shaped scatter plots with overlapping markers, then rotates the resulting graph.

<lang julia>using Colors

using GeometryBasics: Rect3f

using GLMakie

topbar = vec([Point3f(i / 5, j / 5, k / 5) for i in 1:7, j in 8:3:28, k in 45:50])

stem = vec([Point3f(i / 5, j / 5, k / 5) for i in 1:7, j in 1:7, k in 1:8:56])

midbar = vec([Point3f(i / 5, j / 5, k / 5) for i in 1:7, j in 8:2:21, k in 25:29])

fig = Figure(resolution = (800, 400))

pos = fig[1, 1]

meshscatter(pos, topbar; marker = Rect3f(Vec3f(-0.5), Vec3f(16)), transparency = true,

color = [RGBA(positions[i]..., 0.5) for i in 1:length(positions)])

meshscatter!(pos, stem; marker = Rect3f(Vec3f(-0.5), Vec3f(16)), transparency = true,

color = [RGBA(positions2[i]..., 0.5) for i in 1:length(positions2)])

meshscatter!(pos, midbar; marker = Rect3f(Vec3f(-0.5), Vec3f(16)), transparency = true,

color = [RGBA(positions3[i]..., 0.5) for i in 1:length(positions3)])

for _ in 1:28

display(fig.scene)

rotate!(Accum, fig.scene, 0.25)

sleep(0.25)
