Description Usage Arguments Details Author(s) References See Also Examples

Produces a COLLADA file representing the 3D model of a rectangle with the image specifies via href wrapped over the surface (as texture fill). This allows free rotation of any rectangular image in the 3D space.

makeCOLLADA.rectangle(coords, filename, href, DateTime, 
          up_axis = "Z_UP", authoring_tool = "plotKML", 
          technique_profile = "GOOGLEEARTH", 
          double_sided = TRUE)

`coords`	a matrix defining the rectangle: 4 points with X, Z and Y coordinates (P1 — upper right, P2 — upper left, P3 — lower right, P4 — lower left)
`filename`	output filename with `*.dae` extension
`href`	location of the image used for wrapping (texture fill)
`DateTime`	creation / update time (system time)
`up_axis`	specify which axis is errected
`authoring_tool`	specify authoring tool
`technique_profile`	specify technique profile
`double_sided`	logical; specify whether to drape image on both sides

COLLADA is managed by the nonprofit technology consortium, the Khronos Group. You can also simply drag and drop a COLLADA (.dae) file on top of the virtual Earth.
