HopfTorusMesh: Hopf torus mesh

In cgalMeshes: R6 Based Utilities for 3D Meshes using 'CGAL'

Hopf torus mesh

Description

Triangle mesh of a Hopf torus.

Usage

HopfTorusMesh(nlobes = 3, A = 0.44, alpha = NULL, nu, nv)

Arguments

nlobes	number of lobes of the Hopf torus, a positive integr
A	parameter of the Hopf torus, number strictly between 0 and pi/2
alpha	if not NULL, this is the exponent of a modified stereographic projection, a positive number; otherwise the ordinary stereographic projection is used
nu, nv	numbers of subdivisions, integers (at least 3)

Value

A triangle rgl mesh (class mesh3d).

Examples

library(cgalMeshes)
library(rgl)
mesh <- HopfTorusMesh(nu = 90, nv = 90)
open3d(windowRect = 50 + c(0, 0, 512, 512))
view3d(0, 0, zoom = 0.75)
shade3d(mesh, color = "forestgreen")
wire3d(mesh)
mesh <- HopfTorusMesh(nu = 90, nv = 90, alpha = 1.5)
open3d(windowRect = 50 + c(0, 0, 512, 512))
view3d(0, 0, zoom = 0.75)
shade3d(mesh, color = "yellowgreen")
wire3d(mesh)
