elevation

问题 I'm rusty a bit here. I have a vector (camDirectionX, camDirectionY, camDirectionZ) that represents my camera direction of view. I have a (camX, camY, camZ) that is my camera position. Then, I have an object placed at (objectX, objectY, objectZ) How can I calculate, from the camera point of view, the azimut & elevation of my object ?? 回答1: The first thing I would do, to simplify the problem, is transform the coordinate space so the camera is at (0, 0, 0) and pointing straight down one of the

问题 I do not know if this approach is the best, but I have the following problem: I want a list item (a CardView) in a RecyclerView to be animated when it's button was clicked, so that this button, some other views inside this item and the background of the CardView changes. I am catching the animateChange from a custom RecyclerView.ItemAnimator: (until now the animation is just a fade defined in the xml via animateLayoutChanges) public boolean animateChange(@NonNull RecyclerView.ViewHolder

问题 my question is, how to get an elevation profile of the specified route from the MapBox service. On the input we have path / route as the array of coordinates (latitute, longitute). As the result we would like to get the array of the pairs coordinate - elevation. In case the resolution of elevation data is higher than the route coordinates provided, the result should contain also the elevation data between the original coordinates. The new points on the route would be generated according to

问题 I have an elevated console running some bat files. Having this console running in elevated mode is mandatory for it to be able to perform some tasks like managing network shares, etc without asking for permissions. But sometimes the scripts also have to launch some applications which are not desired to run elevated. So we want our elevated bats to start come application in non-elevated mode. Is there any built-in way to do this on Windows? Processes were started with DOS command START up to

问题 I have a small program that is installed in a custom folder in the program files, but when I tried to read or write to files that are needed to operate, the program raises an Access Denied Exeption. How can I elevte the program, with the user's permission of course. 回答1: I guess you're running under Vista? In Vista I don't think you're allowed to read/write to files under Program Files, you should put your data files in Documents and Settings instead. 回答2: To resolve the Access denied

问题 can it be determined that where a person is i.e is he walking ? is he in elevator ? or is he climbing up the stairs ? using android's accelerometer or is there any other way to calculate such in android ? 回答1: You can use a combination of the accelerometer and the digital compass, in phones that have them, to determine a speed and direction as mentioned in this post. If all you need to do is determine if the person is walking, all you need is the accelerometer. Just process its output for

问题 Suppose I have a script that needs to read information from places that normal user is not permitted to read (e.g. other users' folders). Currently all I can do is complain about not being run as a "superuser" and quit, but I would rather like the script to ask for elevation itself. 回答1: According to MSDN and PerlMonks, you can try: Win32::FileOp::ShellExecute( runas => 'yourprogram.exe' ) or Win32::FileOp::ShellExecute( runasuser => 'yourprogram.exe' ) These should (not tested) ask you for

问题 Trying to add elevation (shadow) to View works, however my second View , which renders circle, hides under View with elevation property. If elevation is removed, circle with position: 'absolute' is working properly. Any ideas how to use elevation and position View absolute? My Code: import React, { Component } from 'react'; import { StyleSheet, Text, View, Platform, TouchableOpacity } from 'react-native'; import { Font } from 'expo'; export default class Position extends Component { render()

问题 We have an installer for our application that must be downloaded and run with administrator privileges, like many other installers. However, the installer isn't named "setup.exe", so Windows doesn't automatically detect it as requiring elevation to run. Changing the installer name to make things elevate properly sounds pretty messy, frankly. This article talks a lot about UAC and elevation, and it says that you can use a manifest to make something require authorization. So, we'd just love to

问题 I have a system, I set it up as a normal with UAC, and in my delphi environment I compile my project named ka.exe, I create a installshield project for it. setup and everything completes ok! but whenever I start my program, it requires elevation and I don't have any clue why. just to be sure installshield is not playing mindgames on me, I compiled a new .exe, and copy it manually over to my networked computer. the icon looks the same, and it also have this UAC shield on it. my project has
