Suppose I am building a tool on top of Three.js, and I calculate world matrices of my objects somewhere else outside of Three, and I want to apply the world matrices to the Object3Ds. How can we do this?
const object = new Object3D
object.matrixAutoUpdate = false
// render loop
object.matrixWorld.set( ... )
but this doesn’t work because the world matrices are overriden on each tick: when the renderer calls
scene.updateMatrixWorld() it goes and updates all the world matrices based on local matrices, which overrides my custom values.
What would be the best way to set world matrices manually? Maybe I should set
false, then that way
scene.updateMatrixWorld doesn’t get called, and it renders my values. Giving it a shot…
