GLModel Line Width

in Contributed Library Questions • 2 years ago

Hello,

I am using the GLModel library to make a model with several thousand lines ( example here). I am trying to make some lines appear thicker than others within the same model.

I saw the setLineWidth() function and like how it expands the line cylindrically. Unfortunately, it increases the size of all lines in the model. I saw the linearComb() function from the PDBView example, but I could not figure out how to use it. Is there a way to increase the width of only certain lines within the model?

Thank you so much for your help!!

You can specify a range of vertices in the GLModel to render, and set the desired line width for each portion. Something like this:

lines.setLineWidth(4);
renderer.model(lines, 0, lines.getSize() / 2);
lines.setLineWidth(1);
renderer.model(lines, lines.lines() / 2 + 1, lines.getSize());

Hi Andres,

Thanks for your suggestion! This is a great method to adjust the way the model is rendered. Is there a way to adjust line widths within the model itself?

No, this is currently the only way to specify different line widths in a GLModel object.
