I am trying to construct a perspective plot of a 2D triangle, or pyramid. I
can easily do the one dimensional plot (code below), but I can't figure out
how to do it in a perspective plot for two input variables. Does anyone
have a simple solution?
#code for a triangle
u <- seq(-1,1,.001)
tri <- (1-abs(u))
plot(tri~u,type="l",main="Second Iteration Kernel: Two Input
