Textured Lines

[Randy Frank]

Hello,

   Is it possible to create a LinesMesh object with per-vertex coloring?  It did not look like LinesMesh.color took a per-vertex color array and I tried assigning uvs coordinates with a material that specified a diffuseTexture or an emissiveTexture with no luck.  I'm rendering particle traces as lines and I need to be able to change the color at each vertex along the trace.

TIA.

@Randy Frank - Can you post a Playground scene with what you already attempted which did not provide your expected result?

Sure, here is a simple example:

I have an embedded png texture (256x2) that is just an hsv color ramp.  I would like the lines to be colored using the texture. I also tried vertex coloring.  Obviously I'm missing something here.  Any help would be greatly appreciated. 

Thx.

LineMesh only support static color. But you can still rely on wireframe rendering: http://www.babylonjs-playground.com/#1WKJMI#2

Thanks!

My use case is for independent lines (particle traces, not related to any polygons), changing it to using degenerate triangles in wireframe mode seems to work:

Any potential issues with using triangles like this (e.g. picking, etc)?  I do like the ability to light the lines this way...

nope this is perfectly legit
