I’m got an MorphBlendMesh that I’m animating via AnimationMixer that I would like to add a quad-style wireframe to. Setting “wireframe: true” on the materialobviously doesn’t work, since the triangle approach gives the appearance of the squares that I want, but with “diagonals”. In other words, I wa…

This grid was created with my addon THREEf. The parameters are visible. Almost all default, only style cover and quad line selected. And material cover 0. [20180315-1703-40352] The code can be found at https://github.com/hofk/THREEf.js/blob/dev/THREEf_90/THREEf.js lines 313 and for Geometry an…

Forgot to mention earlier – I’m using r83. Thank you for your replies, but unfortunately I don’t think these will help me. The animation MUST be compatible with AnimationMixer. I’ve come to the opinion that the answer lies within the getWireframeAttribute function of THREE.js. I’m convinced there’s…

Just out of curiousity. Is it working, when you use wireframe?

If you mean the wireframe property of the material, it will animate as normal, but the wireframe appears as in the second picture in the original post.

It’s interesting. Can you provide a live example? (jsfiddle, codepen)

[image] ps111: I’m convinced there’s a way to arrange to indices so that the diagonals will simply not be rendered. Actually, that’s what .toGrid() does. It changes index of an indexed buffer geometry.

I think the solution lies in a function something like the toGrid function, but I’m struggling to figure out how to apply it to my own issue. Your examples all use PlaneBufferGeometry,BoxBufferGeometry, etc. A generic BufferGeometry doesn’t have the widthSegments and heightSegments attributes, which…

If you provide a live example, I can think on that question :slight_smile:

Sorry if this is a stupid question, but a live example of what, exactly? The code in question is within three.js (r83), specifically the getWireframeAttribute function. So, really any mesh whose material has wireframe = true should work as an example.
