as.tmesh3d: 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, ...)
# S3 method for default
as.tmesh3d(x, drop = FALSE, ...)
# S3 method for mesh3d
as.tmesh3d(x, drop = FALSE, keepTags = FALSE, ...)

Value

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

If keepTags = TRUE, a "tags" element will be added to the result. For details, see the clipMesh3d

help page.

Arguments

x

An object from which to create a triangular mesh object.

drop

If TRUE, drop any point or segment components.

keepTags

Whether to include the "tags" component in the output.

...

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.

See Also

as.triangles3d to get just the coordinates.

Examples

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