P3D not working?

[skpai3]

Does Processing.R still work with P3D? I tried something simple like this and got no graphic window:

settings <- function() {
  size(200, 200, P3D)
}

setup <- function() {
}

draw <- function() {
  background(0)
}

I also imported peasycam to try the code below from the tutorial Processing Libraries: importLibrary().
I get error class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')

settings <- function() {
  importLibrary("peasycam")
  size(200, 200, P3D)
}

setup <- function() {
  cam = PeasyCam$new(processing, 100)
  cam$setMinimumDistance(50)
  cam$setMaximumDistance(500)
}

draw <- function() {
  rotateX(-.5)
  rotateY(-.5)
  background(0)
  fill(255, 0, 0)
  box(30)
  pushMatrix()
  translate(0, 0, 20)
  fill(0, 0, 255)
  box(5)
  popMatrix()
}

你好，来件已收到，谢谢！

We do not implement the P3D with this extension. Sorry for that.

@gaocegege This is a great package but it's odd that in your paper as well as in the guides, there appears to be multiple examples of R code implying P3D functionality.

Is that feature something that you were not able to finalize for release? Is it planned or out of scope entirely?

[gaocegege]

Some 3D examples are from the libraries. E.g. https://github.com/processing-r/Processing.R/blob/master/examples/Libraries/He_Mesh/demo.rpde

settings <- function() {
    # Please install the peasycam before you run the example.
    importLibrary("hemesh")
    fullScreen(P3D)
    smooth(as.integer(8))
}

We have some examples in the examples/Libraries folder. I think my response is wrong. It should support P3D. The project was too old. I hardly remember it.

Understandable! For me, the fix turned out to be reverting back to Processing 3.3.6.
