Hello, I know there are several resources on this but I am not able to get a curved plane from a set of Vector3 points. This is the screenshot of the output. [curvedPlanePoints] The ends of red and green line segments represents the boundaries of plane. and I want to make a plane connecting all t…

Hi! The first thought about it is that you have to re-create your geometry when you move or add a point.

I thought so, but isn’t there any way to add points without recreating the geometry? And can you tell me how to make a plane from the set of those points? I have tried using ShapeGeometry but I can create only 2D curved plane which acts as a projection to the figure on the grid.

.setDrawRange ( start : Integer, count : Integer ) : null Set the .drawRange property. For non-indexed BufferGeometry, count is the number of vertices to render. For indexed BufferGeometry, count is the number of indices to render. https://threejs.org/docs/index.html#api/en/core/BufferGeometry Th…

Thanks for the answer. It worked out and now I have a dynamically changing geometry and about the question you asked. Well I have created a catmullrom curve connecting the white points and all the red and green lines are the normals to the curve parallel to x-z plane. Now I got to use the end poin…

If you have the coordinates of the points, it’s no problem. I’ll take a look at it in the evening. Such a road fits well into my addon Addon to create special / extended geometries

I could use my approach from the https://discourse.threejs.org/t/addon-produces-almost-infinite-many-time-varying-geometries-with-functions/262 . https://github.com/hofk/THREEf.js/tree/master/THREEf_90 Totally simplify. An initial approach. [20190217-1806-31310] A motorway with four lanes is al…

It’s not a road, but it’s a nice tape. // calculate here the coordinates according to your wishes tangent = curve.getTangent( j / 100 ); // 100 length segments x = points[ j ].x + tangent.x; y = points[ j ].y + 1; z = points[ j ].z + tangent.z + i / 2; [20190217-2121-51372]

Now there is a four-lane street in colored wireframe. [20190218-1957-52686] <!DOCTYPE html>  <head> <title> FourLaneRoad </title> <meta charset="utf-8" /> </head> <body> </body> <script src="../js/three.min.101.js"></script> <script src="../js/OrbitControls.js"></scrip…

Thank you very much for such a great explanation, it really helped me a lot. I got a road now but I am struggling with creating a line(full line and dashed) in between having some width. setting a scale doesn’t work and line width doesn’t work. Do I have to use a similar plane making technique with …

Yeah sure if it is doable by today it would be most helpful and I hope you got my question right.
