DrawPoints: Visualization of point data
In italo-goncalves/geomod3D: Implicit 3D Geological Modeling and Geostatistics

Adds point information to the current rgl window in the form of colored spheres or points.

DrawPoints(object, ...)

## S4 method for signature 'points3DDataFrame'
DrawPoints(object, by, values, col, size,
  alpha = 1, col.default = "white", as = c("spheres", "points"))

`by`	Name of the column to show.
`values, col`	If `by` is a categorical variable, the values to show and the corresponding color. If `by` is a continuous variable, a numeric vector with the breakpoints and the corresponding colors.
`size`	The diameter of the spheres. Either a single value or a vector matching the object's number of rows.
`alpha`	Opacity factor.
`col.default`	Color to be used for `NA` values and values outside the range provided.
`as`	How to plot the points. For `"points"`, only the color information is used but the visualization becomes much lighter in terms of machine resources.

For categorical variables, each entry in values is matched to the corresponding entry in col. For continuous variables, values is a numeric vector with breakpoints, each of which is matched to the entries in col. The actual values are interpolated to generate a unique color to each value. col must be a character vector containing colors in hexadecimal format, such as "#804DB3", or valid color names.
