There was a feature wich was in MegaPov 0.7 and that I miss a lot : 
Blurred reflection.

How do you fake that feature in POV 3.5.

AFAIK, it's a reflection variation that has not been implemented in 3.5

Thanks

Thanks for your quick answer. It works but it does not seem to be as 
fast as MegaPov for the same accuracy.

Another great feature that I miss ( tell me if I am wrong) is the 
possibility to 'do' an isosurface with a image_map as in :


#local fnc_basketballbump=function {pigment {image_map {png 
"BasketBallBumpNew.png" map_type 1 interpolate 2}}}

#local obj_basketball=isosurface {
   function { fnc_basketballbump(x,y,z)} //+ 
noise3d(x*100,y*100,z*100)*0.01}
   threshold 0
   sign 1
   accuracy 0.001
   method 2
   max_gradient 3.444
   contained_by {box {-1, 1}}
   all_intersections
   texture {txt_basketball}
}

Thanks

Correct...it is faster and has smoother results, as well as being more 
flexible. It is true that it is slower for the same number of samples, 
but you need fewer samples, the situation is the same as for method 3 
media vs. method 1.

Checking the documentation might help. That feature was included, you 
are just using it wrong:

   function { fnc_basketballbump(x,y,z).hf} //+
