Hi everyone, I have managed to calculate the voule of the stl file I uploaded. I can get the distance between two points using p1.distanceTo(p2). However, I’m unable to get the volume of the geometry. It always return 0. Here is my code: var object var loader = new THREE.STLLoader(); …

I have seen my mistake in the code. it’s at the p3.fromBufferAttribute(position, i * 3 + 0); I have fixed it, and the volume calculation is correct when compared to other 3d model calculators. The problem I’m having now is the result of p1.distanceTo(p3) is not correct when I compared it the other…

How exactly are you calculating the volume - can you share a doc or some brief explanation? Why are you calculating triangle volume based only on the z-axis in signedVolumeOfTriangle ? Wouldn’t in this case (nearly-) vertical faces have (nearly-) 0 volume, even though they’d still require filament t…

From what I’ve read so far on calculating volume of 3d model of BufferGeometry, both index and non-index, the formula in the signedVolumeOfTriangle is the one that have been used mostly. From what I understand, the surface of the model is made up of triangle and the volume can be calculated by calcu…
