I have a mesh made like this: var cubes = [] const boxGeometry = new THREE.BoxGeometry(1,1,1); const boxBufferGeometry = BufferGeometryUtils.mergeVertices(new THREE.BufferGeometry().copy(boxGeometry)) var geometry1 = boxBufferGeometry.clone(); var geometry2 = boxBufferGeometry.clone(); …

A very rough and perfectly imperfect attempt :sweat_smile: : https://jsfiddle.net/prisoner849/8krouz01/ [MergedMesh] Feel free to modify it at your will :slight_smile:

Hi! Seems you’re looking for BatchedMesh from @donmccurdy BatchedMesh: Proposal opened 06:48AM - 20 Aug 21 UTC (UTC) [donmccurdy] donmccurdy Suggest…

@prisoner849 Thank you so much for taking your time. Hmm. Looks like there’s no specific working code yet. Is there any other approach, including making mesh in a different way to reduce the draw call?

InstancedMesh: three.js webgl - instancing - performance

Thank you. I know there’s that, but don’t know how to rotate around the local center y-axis. As I wrote in the topic’s description, a working example is appreciated. Would you be able to provide some code?

Maybe just recreate geometry each frame.

Maybe just recreate geometry each frame. That’s a horrible idea.

Also you can merge geometry and into vertex shader check distance to point. If distance<10 then not rotate, else rotate or move.

You’ll get weird results, if objects kind of side by side. Like a tiny sphere right next to a huge box.

uniform mat4[${gs.length}] instanceMatrices; Hey @prisoner849 how would you do this without mat4 being sent as a uniform. What would be the change here to put this on the InstanceAttribute on the shader and avoid 256 max_vertex limit? Would you just need to add a UV Buffer to the matrix of the Batc…

@D13 I would go with DataTexture in a uniform The keyboard is a bunch of merged buffer geometries. DataTexture is kind of a mediator for interaction.

Rotate each buffer geometry that's merged by 'BufferGeometryUtils.mergeBufferGeometries' around each own center?

I think so

But I had fun, making that keyboard: Keyboard of merged geometries
