Hej,
When plotting triangles with rgl.triangles and setting the axes afterwards
with decorate3d(aspect=TRUE), the axes get the color used for the last
triangle plotted.
Example:
rgl.triangles(c(1,2,3),c(1,2,5),c(1,3,2),col="#55FF55")
decorate3d(aspect=TRUE)
Using
decorate3d(aspect=TRUE,col="#000000")
or
decorate3d(aspect=TRUE,color="#000000")
does not help, the axes still have the last color used for plotting an
object.
In the help page of decorate3d on can find the following line:
...: additional parameters which will be passed to 'par3d',
'material3d' or 'decorate3d'.
So the 'color' argument should have an effect.
The workaround is simple. Set the color with rgl.material before calling
decorate3d:
rgl.material(color="#000000")
Maybe this should be done directly in the decorate3d function, as written
in the help?
Version of rgl used: 0.67-2 (2006-07-11)
Version of R used: R 2.3.1; i486-pc-linux-gnu; 2006-07-13 01:31:16;
Anyway, rgl is an excellent package.
