Hello, I have another question.
My scene has a plate with many (about 1000) holes, like following:
difference{
cylinder{<0,0,0>,<0,1,0>,10}
#local X=-9; #while(X<9)
#local Y=-9; #while(Y<9)
#if (X*X+Y*Y < 81)
cylinder{<X,-0.1,Y>,<X,1.1,Y>,0.1}
#end
#local Y=Y+0.5; #end
#local X=X+0.5; #end
}
Rendering of this is very slow, even if I added bounded_by.
On the other hand, if I removed CSG, it is much faster.
How can I improve the rendering speed?
