Can others confirm strange skew in Raster3D ?

Example from documentation of Raster3D , applications section


Graphics3D[{Raster3D[
   List@ImageData[
     ImageResize[ExampleData[{"TestImage", "Lena"}], 200]],
   {{0, 0, 0.4}, {1, 1, 0.6}}]}, PlotRange -> {0, 1}]

Example that better shows strange skew that “restarts” as steep skew goes past boundary


Graphics3D[{Raster3D[List@ImageData[Rasterize[
      ExpressionCell[Style["Hello", 80, Red], "Output", 
       Background -> None], "Image", Background -> None, 
      ImageResolution -> 40]], {{0, 0, 0.4}, {1, 1, 0.6}}]}, 
 PlotRange -> {0, 1}]

Would expect just to be extruded image of “Hello”

I’m not seeing this issue on my machine.

What OS are you using? Additionally, what graphics card? If you haven’t tried already, consider resetting Mathematica to its default installation configuration:

Most likely this is an issue that you’d wan to report to support@wolfram.com. It’s possible they may have seen it before.

Thanks for the reply

also I should have described it as a shear transform that seems to be applied to bitmaps under Raster3D
