Thanks a lot!  
I read something about depth peeling , have a general idea of it.

I do as you say,I call the  
[UseDepthPeelingForVolumesOn](https://vtk.org/doc/nightly/html/classvtkRenderer.html#a91bb9e0129f8d73173a945d65a0811d8)  
[UseDepthPeelingOn](https://vtk.org/doc/nightly/html/classvtkRenderer.html#a4e9d72654eb7972a6abf82fbeb2a8a66)

it works!!! 😀

but it seems there is no different when i call the function of render window using different parameter;

when i call them as you say  
SetAlphaBitPlanes(1)  
SetMultiSamples(0)  
the rendering result is

but when call them not as you say  
SetAlphaBitPlanes(0)  
SetMultiSamples(1)  
the rendering result is

I can’t see the difference, I’m a little confused, could you tell me The differences between the two approaches??
