Hello everybody,
I'm trying to display two 3D figures into the one plot. What I'd like to do is to set the different parameters for them in order to make the figure clear and readable (since they are overlapping each other). Concretely, the desired goal could be surface with a certain colormap vs single color mesh with lower transparency.
Maybe I'm going to use fill3 instead of mesh but even then I'd like change its properties (transparency, color).
Thank you people. King regards, Vasek

There are lots of properties for a surface object that allow you to control transparency.
You can also use ALPHA to quickly apply transparency:
h = surf(peaks);
alpha(h, 0.5)
There are also lots of properties and helper functions for coloring. See Coloring Mesh and Surface Plots.

Thank you Jacob for the answer. Actually, I'd tried to apply colormap and alpha function before.
The problem is that once you use these functions, the all displayed "figures"(surface, mesh) are influenced.
I set colormap for my surface, and a certain alpha and color for my mesh. It ends in the same colormap and transparency for both of them. What I'd like to achieve is to have mesh and surface in one plot but both of the with different properties

The ALPHA function lets you specify a particular surface to apply to:
>> s1 = surf(peaks);
>> hold on;
>> s2 = surf(peaks+5);
>> alpha(s2, 0.1);
However, COLORMAP does not provide this fine of control and applies the map to either the entire figure or axes. To use multiple colormaps in a single figure, there is a technical support guide:

Great that's exactly what I'm looking for.
Alpha together with hold_on works great, thank you... I try to go for that multiple colormaps as well, it looks promising.
Thanks.
King regards, Vasek
