问题 I am creating an app where I need to change textures(pattern) of my 3d object. I am using AR Core SDK and android. I have used the below code but it is not working. Texture.builder() .setSource(this,R.drawable.fabric3) .build() .thenAccept(t -> { BaseTransformableNode node = arFragment.getTransformationSystem().getSelectedNode(); if(node!=null){ node.getRenderable().getMaterial().setTexture("baseColorMap",t); } }); Documentation is also not helping me much. This is my SFA file { animations: [

问题 I have problem with the objects generated from Google Sceneform Tools ​(Beta)​ v1.13.0 in Android Studio. I downloaded the object ( .obj file ) from poly and imported to Blender to change the dimensions. After that exported again as .obj file . When I use it to generate .sfb file in Android Studio with Sceneform tools, the .sfb object that is generated is only black. Left is object ( .obj and .mtl ) imported in Blender , and right is generated .sfb file in AndroidStudio. Thanks in advance.

问题 In application with ARCore and Sceneform I need somehow monitor my (device, really) movement in ARCore space? As result I want to draw a ray from selected point ( Anchor / AnchorNode ) through my current position, or to calculate distance from selected point to here, and update them during movement. I have ideas, how to calculate or draw, but how to get updates? 回答1: First setup an On Update listener fragment.getArSceneView().getScene().addOnUpdateListener(frameTime -> { fragment.onUpdate

问题 I'm trying to track facial expressions such as eyebrow raise, smile, wink, etc. In ARKit I could use blendShapes (https://developer.apple.com/documentation/arkit/arfaceanchor/2928251-blendshapes) to detect the movement of the different parts of the face but in ARCore it doesn't exist yet. I've tried to access the mesh vertices which are relative to the center transform of the face but these change significantly with the rotation of the face. Is there a way to normalize the face landmark
