# Hi- Not sure what’s going on, but I got different results between add\_surface and persp3d/persp. Any help is appreciated! Thanks!!

kd \<- with(MASS::geyser, MASS::kde2d(duration, waiting, n = 50))  
plot\_ly(x = kd$x, y = kd$y, z = kd$z) %\>% add\_surface()  
persp3d(x = kd$x, y = kd$y, z = kd$z, col=“yellow3”)  
persp(x = kd$x, y = kd$y, z = kd$z, col=“yellow3”, ticktype = “detailed”, phi=15, theta=45)
