How can I dot some pionts on spheric surface in "3D parametric surfaceGraph"

[yangyang-rexxar]

HI

    I have built a spherical to Cartesian coordinates(like the picure sample).

When I finished the sphere I need to dot some points(like the picture sphere),

There're 2 idea to actualize.

One is Draw multi 3D surface,first is sphere,another is some points,but I want the pionts is dynamic ,they're dotted one after one that looks like a queue.The idea is not satisafy.

The other idea for me is Replace some point in Sphere Array,

But I want the sphere looks like fixed and silent,points is dotted one after one as a dynamic scaning.

How can I resolve the problem????

HI Paulbin,

I see you also posted here.

It sounds like you want to post one plot and then add another as the data comes in. If so, please take a look at my postings that start with rely #7 of this thread.

It is a "worse case" example but amoung other things, I show how to add new plots and manipulate their properties.

If that does not help, please post some demo code so other can jump in and help.
