Examples

# Draw a teapot
data(teapot)
p <- plot3js(
  xlim = range(teapot$vertices[,1]),
  ylim = range(teapot$vertices[,2]),
  zlim = range(teapot$vertices[,3]),
  label_axes = FALSE,
  aspect = c(1, 1, 1)
)

p <- shape3js(
  p,
  vertices = teapot$vertices,
  faces = teapot$edges,
  col = "lightblue"
)

r3js(p, rotation = c(-2.8, 0, 3.14), zoom = 1.2)
