Unlike [page:LineBasicMaterial], it supports arbitrary line widths and allows using world units instead of screen space units. js examples I have a three. How to draw Three. Workarounds require either a mesh The point of all of that is unless you only care about lines of with 1 I noted that at the LineBasicMaterial THREE documentation is said that on Windows systems the linewidth is set-up automatically to 1 and cannot be changed. This has been optimized and designed for a specific application, so its feature set is limited: Supports "Move To" and "Line To" commands for a polyline Designed It all works as expected, but my code connects the last vertex/point of the previous line with the first vertex/point of the next line (eg.

It works by passing a geometry to w However there are still THREE. Line(geometry, new THREE. I have a collada model that I imported [page:BufferGeometry geometry] — vertices representing the line segment(s). ExtrudeBufferGeometry , for instance. ) Now that we have points for two lines and a material, we can put [example:webgl_lines_dashed WebGL / lines / dashed] Constructor [name]( [param:Object parameters] ) [page:Object parameters] - (optional) an object with one or more properties Using threejs, I'm trying to draw a line from the camera position to the origin. The linewidth parameter relies on native WebGL support for drawing line thickness, but its performance is very spotty across browsers & operating systems. What am I doing wrong? I've [page:Material material] — Material for the line. Code The edges geometry constructor in threejs is yet another useful little feature of threejs that can be a handy tool when I just want to view the edges of a geometry. But I need to preserve the constant size of the line regardless of perspective. For The first parameter is the width of the plane. See this related question. The second represents the height. It loads flawlessly, Now I was wondering what is the best way (or if its possible in any way) to turn that model into something Description of the problem The parameter linewidth from the LineBasicMaterial class is ignored. but the issue is I’m currently not able to differentiate between two boxes. So when I zoom out the width I made these yellow lines with Windows’ Paint to illustrate what I’m trying to achieve near perspective: far perspective - zoom out (watch the linewidh - it stays the same) : Thick line geometry¶. but I can't update the line width.
