plotCones3D: Plot a cone defined by a point in 3D.

In relund/gMOIP: Tools for 2D and 3D Plots of Single and Multi-Objective Linear/Integer Programming Models

Plot a cone defined by a point in 3D.

Description

The cones are defined as the point plus R3+.

Usage

plotCones3D(
  pts,
  drawPoint = TRUE,
  drawLines = TRUE,
  drawPolygons = TRUE,
  direction = 1,
  rectangle = FALSE,
  useRGLBBox = TRUE,
  ...
)

Arguments

pts	A matrix with a point in each row.
drawPoint	Draw the points defining the cone.
drawLines	Draw lines of the cone.
drawPolygons	Draw polygons of the cone.
direction	Ray direction. If i'th entry is positive, consider the i'th column of pts plus a value greater than on equal zero (minimize objective $i$). If negative, consider the i'th column of pts minus a value greater than on equal zero (maximize objective $i$).
rectangle	Draw the cone as a rectangle.
useRGLBBox	Use the RGL bounding box as ray limits for the cone.
...	Further arguments passed on the the RGL plotting functions. This must be done as lists (see examples). Currently the following arguments are supported: argsPlot3d: A list of arguments for rgl::plot3d. argsSegments3d: A list of arguments for rgl::segments3d. argsPolygon3d: A list of arguments for rgl::polygon3d.

Value

Object ids (invisible).

Examples

ini3D(argsPlot3d = list(xlim = c(0,6), ylim = c(0,6), zlim = c(0,6)))
plotCones3D(c(4,4,4), drawLines = FALSE, drawPoint = TRUE,
           argsPlot3d = list(col = "red", size = 10),
           argsPolygon3d = list(alpha = 1), rectangle = TRUE)
plotCones3D(c(1,1,1), rectangle = FALSE)
plotCones3D(matrix(c(3,3,3,2,2,2), ncol = 3, byrow = TRUE))
finalize3D()

ini3D(argsPlot3d = list(xlim = c(0,6), ylim = c(0,6), zlim = c(0,6)))
plotCones3D(c(4,4,4), direction = 1)
plotCones3D(c(2,2,2), direction = -1)
plotCones3D(c(4,2,2), direction = c(1,-1,-1))
ids <- plotCones3D(c(2,2,4), direction = c(-1,-1,1))
finalize3D()
# pop3d(id = ids) # remove last cone
