Simple projection
« on: December 24, 2018, 09:34:15 PM »
Hi,

I'm looking to project an object onto a surface without any specific spline.
Like this:

Or like this:



I have a big mesh that represent roads, and a surface that represent the ground.
I just want to place the roads above the ground and use raiclone to project it. However, if I use a spline it changes the alignment.

Thanks.

Can Railclone do that?
Thanks.

Hi, you can use a Surface node to conform the segments to a mesh.

Anyway, it was designed to project multiple small segments (i.e. creating the road with RailClone), not to project a single big mesh.
In this case, i don't see any benefit to use RailClone, instead a specialized mesh tool.

Thanks.

I understand, but it would be great if I could use railclone for other things too if possible, replacing other small scripts.

Can I use the surface node without a spline? I just need a Z projection.

Well, you can use a very short spline as reference, and then turn off Segment->Slice.
That should create a single segment with the object. Next, just attach a Surface node to conform it.

Although it's possible to not use a spline at all (setting a non zero value to Generator->X Size), is not practical for this case because the Segment will be placed at [0,0,0], and you cannot move it.
This technique is used normally for nested RC objects, or for Clipping areas, where the position of the Segment is defined by other parameters.
