问题 I'm developing a wearable app and I've noticed a strange behaviour. I have a class FooService extends Service implements SensorEventListener and I've override onSensorChanged() method: @Override public void onSensorChanged(SensorEvent sensorEvent) { if (sensorEvent.sensor.getType() != Sensor.TYPE_ACCELEROMETER) { Log.e(TAG, getString(R.string.err_wrong_sensor_registered)); return; } float x = sensorEvent.values[0]; float y = sensorEvent.values[1]; float z = sensorEvent.values[2]; ... } This

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . I'm trying to understand how coding in openGL works. I found this code on the internet and I want to understand it clearly. For my vertex shader I have: Vertex uniform vec3 fvLightPosition; varying vec2 Texcoord; varying vec2 Texcoordcut; varying vec3 ViewDirection; varying vec3

Ambient light sensors in iphone

问题 In our app, If a user covers the top area of iphone where ambient light sensors are available, i want to get the changing value of ambient light sensors. I don't want to manipulate those value as i understand Apple doesn't allow to play with hardware . My objective is to get that value of ambient light sensors. This is testing application which is checking if ambient light sensors are working correctly or not. I spent lot of time, but couldn't find any thing yet. I tried with

Android Wear detect ambient screen mode

由 六月ゝ 毕业季﹏ 提交于 2019-12-13 18:28:35
问题 Is there a way to detect when the watch is in ambient screen mode? I make a watch face and want to continue to update the clock when the ambient screen mode is on (clock is shown on screen), but I want to stop updating when the screen is off. For now, I start and stop the update in onPause and onResume methods, but the onPause method is called when the ambient screen mode comes on. Thanks. 回答1: To be notified of the Ambient mode changed, you have to use a DisplayListener . You can find the

问题 I have two models Model and its subclass ClientModel an ambient module. Now I want to declare a set of attributes of ClientModel from an interface so called Client . How can I do it? I can imagine something like this: interface Client { name: string; email: string; } declare class ClientModel extends Model implements Client { // with name and email here without redeclare them } 回答1: You can use declaration merging. If the class and the interface are declared in the same namespace/module and

OpenGL shimmering pixels artifact

问题 I'm trying to implement ambient occlusion on a voxel-based mesh and get these flickering white pixels at the edges of faces: Here is my fragment shader: #version 120 varying vec4 color; varying vec4 normal; void main(void) { float light = normal.w + max(0.15*dot(normal.xyz, vec3(1,1,1)), 0.0); gl_FragColor = vec4(color.xyz * light, 1.0); } If I remove the light from the gl_FragColor vec4 then the artifact disappears. The light value is calculated from the ambient occlusion value ( normal.w )

How to support new ambient mode in android wear?

由 ぐ巨炮叔叔 提交于 2019-12-08 10:32:17
问题 Since last update Android Wear has a new feature - the always-on mode. This means that the Android Wear device doesn’t turn off the screen; it changes to the ambient mode to save battery and keeps certain apps running in the background. How exactly should I implement this? p.s. I'm developing sport application, not watchface. 回答1: What you're looking for is how to support "Ambient Mode" in your Wear app's activity. There is an entire doc dedicated to this: http://developer.android.com
