[vtkusers] minimum size of scalar glyph

[Adam Bruss]

We are using that scale but we also want a minimum size glyph so very
small scalars up all the time. 

 

We are using scalar glyphs to represent particles that have weight. The
heavier the particle, the bigger the sphere is in vtk.

 

Thanks,

Adam

Hi Adam.

 

The vtkGlyph3D has a function ->SetScaleFactor(). You can set a number >
1 so increase the size of the glyphs.

Maybe this will help you.

 

But does a glyph representation of scalar data makes sense?

Thought it would be more useful for vector data?

Betreff: [vtkusers] minimum size of scalar glyph

 

Hello,

 

We're using vtkglyph3d to represent scalar data. Some of the scalars
show up as very small spheres. We would like to set a minimum size that
the spheres can be. One can set the PointSize property of an actor to
control size. Is there a way to set a minimum size for scalar data
rendered with vtkglyph3d? Sort of like anything smaller than x gets the
size of x.

 

Thanks,

Adam
