Is there a way to control an outlines visibility from different angles? #49

This might be kind of a crazy question, but is there a way to add or remove outlines on the same mesh in Malt? What I'm trying to achieve is to see a specific line from one angle but have it fade/vanish when it's viewed at another angle. Hope this makes sense, my brain has turned to mush a bit as I try to figure it out. I thought doing something with data transfer might work, though I am not very familiar with the modifier and how to use it. I got something close to what I wanted when I made a second mesh and used smooth + project face interpolated on the original mesh, but lost some of the outlines I wanted to keep. I added a pic to help illustrate what I've tried/am trying to do. Thanks in advance to anyone who has suggestions. :)

Yes, you could drive the thresholds, the line width and/or the line color with textures or vertex colors. But you need to make your own shader for that. Are you familiar with GLSL? I think the easiest way for your use case would be just scaling the line width with a vertex color. Now create a vertex color layer for your mesh. The white parts will render the line as previously and the black ones won't have lines. |

I actually don't know all that much about coding and had to look up what GLSL is. But I am willing to learn if it helps get the results I need. I will look up how to make a vertex color layer and look at your "From Nodes To Code" tutorial. :) Thank you for taking the time to answer my questions. :D |

Start with the advanced_line example and change the line that says:
PO.line_width = line;to:
PO.line_width = line * S.color[0].r;Now create a vertex color layer for your mesh. The white parts will render the line as previously and the black ones won't have lines.
