Hello Guys,

I am having a problem plotting a graph from some sets of point. Please how do I plot a graph having some set of point.

Thanks. 

The distance from the point to the surface easily calculated using the NLPSolve of Optimization package. If the point is not special, we will find for it a point on the surface, the distance between these two points is the shortest between the selected point and the surface.
Two examples:  the implicit surface and the parametric surface.
To test, we restore the normals from the  calculated  points (red) by using analytical equations.

I created a regular 2D without specifying the number of points. I tried to change its style from "line" to "point", but i cannot see the symbols because there are too many points and so all i see is a thick black line. Is replotting with less points the only way, or can I interactively reduce the number of points? 

hello,
I try to draw together point (0,0,12) and the line  x=4t, y=-2t, z=2t on one graph 3D. Somebody has some pointers? Thank you

Hi all, 

 

I was wondering if it is possible to add a colour gradient to a point plot to represent another perameter in the data.

 

 

For example, each point corresponds to a value of 'f' ranging from 0.1 to 1, and I was wondering how to display this by means of a colour gradient.

 

 

Thanks,

How can I add fixed point to the surface in 3 dimensions ?
