Graphics, Figures & Tables ⇒ tikz-3dplot | Spherical Plot without visible Lines

[tomtom]

Hello everybody,

just took notice of the tikz-3dplot package and especially the \tdplotsphericalsurfaceplot macro.

Is there any way to omit drawing the lines, e.g. in http://www.texample.net/tikz/examples/s ... th-3dplot/?

[…] Is there any way to omit drawing the lines […]

Which lines do you exactly mean? Did you already take a look at the tikz-3dplot manual?


Best regards and welcome to the board

Yes looked at the manual. Couldn't find any answer there.
I mean the black lines (example) other than the axis (surface lines on sphere).
Changing the color makes no sense, passing no line color argument, doesn't work and setting the linewidth to zero by: \pgfsetlinewidth{.0pt} compiles, without errors, but doesn't change the lines.
Beyond this, I tried setting draw opacity=1, but this ruled out the underlying surface as well.

tikZ cannot handle (in)visible lines and areas ...

[tomtom]

Is there at least a way to reduce the line width?

It sort of can, with the transparent!0 color, though it's still slightly visible. Alternatively you could set the opacity of the line to 0.0:

tikZ cannot handle (in)visible lines and areas ...

It sort of can, with the transparent!0 color, though it's still slightly visible. Alternatively you could set the opacity of the line to 0.0:

that is not handled by tikZ ...
pst-solides3d can handle invisible lines and areas

No, you're wrong. Did you even try that miniexample I gave? Here's a full example to make it even clearer:

Notice that the line from (0,0) to (4,4) is invisible. In fact, the nodes at both ends of that line would also be invisible if I had omitted the opacity=1 option. And the filled circle in the upper left corner is also invisible. So not only can TikZ handle invisible lines and areas, it can handle invisible labels as well.

please can i have a same resulte but without color, or with one color like red for exemple
