I am new to three.js and I was trying this code but I encountered unexpected output so wanted to check what I am doing wrong here or looking to find reason behind output i am seeing.

I have a bunch of points that are part of each cube face and are set in consecutive order.
when passing all those points to the LineGeometry there is a diagonal lines as a result of connecting all the data points. Is there a way of jumping onto a new point?
What I tried is to set vertex colors, however, it creates a weird effect and I also can not set a transparent color.

I’ve just followed this fat line tutorial from threejs examples
https://github.com/mrdoob/three.js/blob/master/examples/webgl_lines_fat.html#L105

So I have a cube mesh placed at a random location:

I tried setting the wireframe prop as true to render the edges as lines. However, since the mesh is made out of triangles, all it’s edges get visible. I only want to render the boundary lines from the cube!

I began learning Three js and it has been bothering me that some of the lights does not work for me. While following a tutorial on Youtube (https://www.youtube.com/watch?v=XXzqSAt3UIw&list=PLjcjAqAnHd1EIxV4FSZIiJZvsdrBc1Xho&index=2), everything works fine except for the lights that are supposed to illuminate the planets (like in the video at 4:21). When I tested it out, there is not even the faintest light illuminating any planets.

I have tried over the last days to implement a working animated camera to my already running MMD / PMX environment.

I learning three now and i had error. This my problem :
Error: R3F: Hooks can only be used within the Canvas component!
My code:

I’d like to clip or earcut the corners of an extruded mesh at a 45 degree angle so that it produces a trapezoid shape. Consider the following:

I’m attempting to recreate some of the features of the sun shown here. I’ve managed to create a dynamically changing surface using shaders. However, I’m unable to create the flares (arcs in the demo) that rise up and drop down. How would one go about adding those arcs that rise and drop down to an existing shader.
