问题 I'm trying to make a component in A-frame that will move the player/camera in the direction the camera is facing. It should not move anywhere on the y plane, only in the x/y plane. The current setup in the dom is: <a-entity> <a-camera></a-camera> </a-entity> I want to move the entity element position to x units in the current camera direction but it should not move anything on the y-plane. I have tried various solutions but they seem to introduce some weird shift in the camera. 回答1: You could

问题 I am trying to make a 3D viewer for building models. We have the model loaded and are trying to make some sort of interaction with the model. Therefor we are using OrbiControls for rotating, panning and zooming the model. We want to have the behaviour in the viewer that when a user clicks and drags (thus rotating), the rotation center is at the point of the building where the user clicks. I thought I was wise by changing the target of the OrbitControl as such: control.target.set(newX, newY,

问题 I need to preload some obj+mtl files with Three.js (It's not the same file) and I need call another function when all the objects have been loaded. I tried putting a boolean variable that changes when every obj has been loaded and doing a function that confirms if all the objects have been loaded but it didn't work, for some reason the page crash. I have all the obj and mtl paths in an array. This is an example of what I'm doing. http://pastie.org/10297027 I tried to put the load function in
