问题 I recently developed an AR program using Unity3D and built it as a mobile application program. Right now, I am planning to import the Unity program into Android Studio so that I can make it as an activity class.

If so, what should I do to make this possible? Thanks in advance. 回答1: There is no direct way to do this, when you

问题 I'm trying to render objects further away than 1000. let box = SCNBox(width: 500, height: 500, length: 500, chamferRadius: 0) let boxNode = SCNNode(geometry: box) boxNode.position = SCNVector3(0, 0, -2000) sceneView.scene.rootNode.addChildNode(boxNode) From this this answer I know that ARKit directly sets SCNCamera's projectionTransform. So is there anyway I change this projectionTransform in order to render objects further away? 回答1: In ARKit_2.0 / SceneKit_2018 , if a distance from ARCamera

问题 With reference to the question asked here Drawing a line given the angle and a point on the line, I have written a python function "find_normal" which returns the slope and y-intercept of the normal vector to a given point at given angle. Now I have a list of points and I want to verify if these points are beyond that normal vector in the direction of given angle of not. e.g. Angle = 180: True if point is to the left of the line, false otherwise Angle = 0: True if point is to the right of the

问题 I am making a augmented reality / voice recognition app using Phonegap, wikitude and voicerecognizer (phonegap plugin). Almost everything works: The app launches the native speech api, saves the result in an input field, and then starts de wikitude ARchitect view.
