This function saves a large part of the RGL state associated with the current window to a variable.

x |
An object of class |
add |
Whether to open a new window, or add to the existing one. |
... |
Additional parameters, currently ignored. |
The components saved are: the par3d
settings, the material3d
settings, the bg3d
settings, the lights and the objects in the scene.
In most cases, calling plot3d
on that variable will
duplicate the scene. (There are likely to be small differences, mostly internal, but
some aspects of the scene are not currently available.) If textures are used,
the name of the texture will be saved, rather than the contents of the
texture file.
Other than saving the code
to recreate a scene, saving the result of scene3d
to
a file will allow it to be reproduced later most accurately. In roughly decreasing order of fidelity,
writeWebGL
, writePLY
, writeOBJ
and writeSTL
write the scene to a file in formats readable by other software.
The scene3d
function returns an object of class
"rglscene"
. This is a list with some or all of the components
par3d |
The results returned from a |
material |
The results returned from a |
bg |
A list containing some of the properties of the scene background. |
bbox |
A list containing some of the properties of the scene bounding box decoration. |
objects |
A list containing the RGL lights and objects in the scene. |
The objects in the objects
component are of class
"rglobject"
. They are lists containing some or all of the
components
id |
The RGL identifier of the object in the original scene. |
type |
A character variable identifying the type of object. |
material |
Components of the material that differ from the scene material. |
vertices, normals, etc. |
Any of the attributes of the object retrievable by |
ignoreExtent |
A logical value indicating whether this object contributes to the bounding box. Currently this may differ from the object in the original scene. |
objects |
Sprites may contain other objects; they will be stored here as a list of |
Lights in the scene are stored similarly, mixed into the objects
list.
The plot3d
methods invisibly return a vector of RGL object ids
that were plotted. The print
methods invisibly return the
object that was printed.
