plot.obj: Plot OBJ form

In hypertidy/obj: Read 'Wavefront .obj' Files

Description

The value for 'face_colour' is expanded to the length of the number of faces, so the application is discrete to each face, rather than varying between vertices.

Usage

## S3 method for class 'obj'
plot(x, ..., face_colour = "grey", homog = 1)

Arguments

x	obj model see 'read_obj'
...	passed to 'rgl::shade3d'
face_colour	colours to apply to faces
homog	homogeneous fourth coordinate, defaults to 1

Value

the rgl shape3d object, invisibly

Examples

#x <- read_obj("https://raw.githubusercontent.com/Cecropia/thehallaframe/master/models/david.obj")
#plot(x)
#plot(x, col = "grey")
#plot(x, col = "grey", homog = 1.5)
#plot(x, col = "grey", homog = 2)
#lapply(seq(1.5, 4, by = 0.5), function(a) plot(x, col = "grey", homog = a))
f <- system.file("extdata/greek_bust.obj.zip", package = "obj")
obj <- read_obj(f)
lapply(seq(1.5, 4, by = 0.5), function(a) plot(obj, col = "grey", homog = a))
