I sent a bug-report to Wolfram and the case number is [CASE:3454878]


I'm on Linux with Mathematica 10.3 and I have my 3D graphics output set to the highest "Antialiasing Quality". It works fine for Plot3D

Plot3D[Sin[x + y^2], {x, -3, 3}, {y, -2, 2}]

Mathematica graphics

but in a ListDensityPlot3D the axes and the box show step-artifacts

data = Table[Sin[x] Cos[y] Sin[z], 
  {z, -5, 5, 0.1}, {y, -5, 5, 0.1}, {x, -5, 5, 0.1}];
ListDensityPlot3D[data]

Mathematica graphics

The same happens for Raster3D objects in general or when I combine Raster3D with a smoothed 3d plot.

Graphics3D[{Raster3D[RandomReal[1, {5, 5, 5}]]}]

Mathematica graphics

  • $\begingroup$ I can confirm this behavior in MMA 10.3 on Win7-64, also with antialising set to max. One step further even: the axes are antialiased correctly (no step artifacts) while I rotate the plot with the mouse; when I let go, however, they go back to the situation shown here. PS: it may be useful to add the code that produced your figures. $\endgroup$ – MarcoB Oct 27 '15 at 14:47
  • $\begingroup$ @MarcoB This is odd. For me it is always the other way around. While I'm rotating, the plot and the axes are not antialiased and the moment I release the graphics it jumps to it's full beauty. It's just not working for ListDensityPlot3D. $\endgroup$ – halirutan Oct 27 '15 at 15:12
  • $\begingroup$ Same on OS X. In general, having a Raster3D in the graphics prevents antialiasing. Are you sure it's a bug? Doing volume rendering might impose limitations on antialiasing. Maybe it's just a performance-related choice. Rotating these is pretty sluggish on my machine. $\endgroup$ – Szabolcs Oct 27 '15 at 15:17
  • $\begingroup$ You can try this if you're exporting figures for publication mathematica.stackexchange.com/a/200/12 $\endgroup$ – Szabolcs Oct 27 '15 at 15:18
  • $\begingroup$ @Szabolcs I see your point, but the weird thing I was trying to point out is that the axes seem to be properly antialiased while rotating the plot (which indeed is very sluggish), but not when the user is not interacting with it. Here is an animated gif of what I see: image $\endgroup$ – MarcoB Oct 27 '15 at 15:21
