tetramesh {geometry} | R Documentation |
Render tetrahedron mesh (3D)
Description
tetramesh(T, X, col)
uses the rgl package to
display the tetrahedrons defined in the m-by-4 matrix T as mesh.
Each row of T
specifies a tetrahedron by giving the 4
indices of its points in X
.
Usage
tetramesh(T, X, col = grDevices::heat.colors(nrow(T)), clear = TRUE, ...)
Arguments
T |
T is a |
X |
X is an n-by-2/n-by-3 matrix. The rows of X represent |
col |
The tetrahedron colour. See rgl documentation for details. |
clear |
Should the current rendering device be cleared? |
... |
Parameters to the rendering device. See the rgl package. |
