viewAxis: Set the View of the ‘rgl’ Scene

Description

Set the view of the current ‘rgl’ scene aligning one vector perpendicularly to the screen and placing another one in the horizontal plane.

Usage

viewAxis(V1, V2)
viewXY()
viewYZ()
viewZX()
viewAB(cryst1)
viewBC(cryst1)
viewCA(cryst1)
viewInertia(x, m = NULL)

Value

No return value, called for side effects.

Arguments

V1: a length 3 numeric vector.
V2: a length 3 numeric vector.
cryst1: an object of class ‘cryst1’.
x: an R object containing atomic coordinates.
m: a numeric vector containing atomic masses.

Details

viewAxis set the view of the current rgl scene (by setting UserMatrix; see par3d for more details) so that V1 is perpendicular to the screen and V2 is in the horizontal plane. The other functions documented here are helper functions calling viewAxis to set the view using particular Cartesian or lattice vectors. For functions viewAB, viewBC and viewCA a ‘cryst1’ object has to be specifyed to define the lattice vectors used to set the view. The function viewInertia computes the inertia tensor from the atomic coordinates and masses (see inertia) and sets the view to its eigen vectors basis set.

Examples

Run this code

x <- read.pdb(system.file("examples/PCBM_ODCB.pdb", package="Rpdb"))
visualize(x, mode = NULL)
viewAB(x$cryst1)

C70 <- read.pdb(system.file("examples/C70.pdb", package="Rpdb"))
visualize(C70, mode = NULL)
viewXY()
viewInertia(C70)
