Buffer Lines
-
Thank you for your suggestions. Dave I will have to play with your option, I can't "picture" it in my head right now. A texture won't work, as there are lanes merging into each other, and the lane widths change. If it were that easy, I would have done that in the beginning.
-
Ryan, I was only wondering about a texture for the center line. Maybe alternating white and the asphalt color.
Do you need help with the projection thing?
-
Dave it would be great if you could help. A texture makes sense for the line, I thought you referring to a texture with the asphalt and lines in as one texture.
-
Ryan, take a look at the attached and see if that along with the following description would help.
From the origin:
- The centerline of your road drawn on the terrain.
- Projected down to a face using Didier Bur's Projection Tools.
- Use Offset to create the limits for the white lines. I only did the outer lines and should have done another on each side for the edge of the asphalt.
- Project the new lines back up to the terrain. You could use Push/Pull and then Intersect Faces for that.
-
Dave thank you, and this looks awesome. So let me ask you this. My highways and ramps are as components (a series of faces) not a terrain. Will this matter?
-
Are they just the center lines now?
-
They would be the edge lines and a number of center lines, as some parts are three lane highways. I may have a way to do it, I will need to try it out. This is where a straight buffer of lines would be great, even if it had to be extruded 1mm to eliminate the Z buffer fighting.
-
I guess I would just look to see what can be done using offset from tools on surface and maybe using the projection as I mentioned. It might be better to intersect the roads with the terrain so you don't have to worry about z-fighting. If your model covers a large area a few millimeters may not be enough to counteract the z-fighting.
-
Dave would it be ok if I shared the model with you? To be honest, I am not following what you are recommending. I can't get my head around it in my situation. I have a Dropbox and Google Drive account that I could post it on.
-
You can send me small example. I'll try to get some time to look at it.
