R: Convert object to a triangular mesh

as.tmesh3d {rgl}

R Documentation

Convert object to a triangular mesh

Description

Converts the quads in a mesh version of an object to triangles by splitting them up. Optionally drops any point or segment components.

Usage

as.tmesh3d(x, ...)
## Default S3 method:
as.tmesh3d(x, drop = FALSE, ...)
## S3 method for class 'mesh3d'
as.tmesh3d(x, drop = FALSE, ...)

Arguments

`x`	An object from which to create a triangular mesh object.
`drop`	If `TRUE`, drop any point or segment components.
`...`	Ignored in the `mesh3d` method, passed to `as.mesh3d` in the default method.

Details

The default method simply calls as.mesh3d(x, ...) and passes the result to the "mesh3d" method.

Value

A "mesh3d" object containing no quads. If drop = TRUE, it will only contain triangles.

Note

Older versions of rgl had a "tmesh3d" class for meshes of triangles. That class is no longer used: as.tmesh3d and tmesh3d both produce "mesh3d" objects.

Examples

x <- cuboctahedron3d()
x             # has quads and triangles
as.tmesh3d(x) # has only triangles
