I am trying to control the radius of a HyperSphere using
textsliders and have been unsuccessful. So I figured I would use
scale! to scale an object. But I have not seen any definition of a Makie Object. I thought that the
HyperSphere would qualify. It does not. Here is a minimal working example that does not work. (I have been able to control the size of markers. So perhaps drawing a mesh with a single sphere would do the trick. But surely, there is another method. Assume I had a cube and all I wanted to do is rotate the cube within a scene with the rest of the objects staying in fixed locations? In the days I was using OpenGL, the use of matrix stacks was useful for this purpose. Thanks for any help and advice.
using Makie, GeometryTypes, AbstractPlotting using LightGraphs, MetaGraphs # For some reason, `using Makie` does not import its functions. const AP = Makie function setupCamera!(scene) cam = cam3d!(scene) #cam.projectiontype = AbstractPlotting.Orthographic #cam. eyepos = Makie.Vec3f0(5, 1.5, 0.5); lookat = Makie.Vec3f0(0., 0., 0.); end function makePlot() marker_size = 0.0002 scene = Scene(); sradius, s_marker_radius = textslider(2f0.^(0.5f0:0.25f0:20f0), "light pos r", start=2f0) sphere = Makie.Sphere(Makie.Point3f0(0), 1f0) mesh!(scene, sphere, color=:red, scale=s_marker_radius) # HOW TO CHANGE SPHERE RADIUS? parent_scene = Scene() hbox(sradius, scene, parent=parent_scene) setupCamera!(scene); display(parent_scene) end # Execute the function makePlot()
