Temporal filtering on depth image

阅读更多关于 Temporal filtering on depth image

问题 I'm reading the following paper and I'm trying to implement it, but it seems I'm not understanding fully the paper. https://vcg.informatik.uni-rostock.de/~malub/publications/2016_depthenhance/16_ARLS_depthenhancement.pdf I have calculated optical flow and some history of the depth images, and took the a linear average over the history samples as shown in the shader code. What I get is an image that has holes however the original one doesn't have any holes. Current filtered image Shader

How to convert a RGB565 Texture to PNG depth image?

阅读更多关于 How to convert a RGB565 Texture to PNG depth image?

问题 Using Googles AR Core Depth API, the current depth information is stored in a RGB565 Texture. If I want to calculate the current depth in a shader I use the following code (which is mostly stolen from Google Depth Lab): #define ARCORE_DEPTH_SCALE 0.001 // mm to m #define ARCORE_MAX_DEPTH_MM 8191.0 #define ARCORE_FLOAT_TO_5BITS 31 // (0.0, 1.0) -> (0, 31) #define ARCORE_FLOAT_TO_6BITS 63 // (0.0, 1.0) -> (0, 63) #define ARCORE_RGB565_RED_SHIFT 2048 // left shift 11 bits #define ARCORE_RGB565

Accessing a script from another script at runtime in Unity C#

阅读更多关于 Accessing a script from another script at runtime in Unity C#

问题 Like in here, but the difference is that it's supposed to be done from an instantiated prefab, so I can not drag the GameObject, that has the script with the variable I want to access, into this script. This was working public ScriptA script; void Update() { if (script.varX < 0) { // . . . } } But now I'm getting "Object reference not set to an instance of an object" error, which I think comes from the fact that the script trying to access ScriptA, is attached to an instantiated prefab.

问题 I'm new to Unity as well as to C# (real noob to C# and all the .NET stuff) and I want to use the Firebase Realtime Database in my Unity project. I was following the instructions on the Firebase docs to set things up, but after I created a new p12 file and added this code to my project void Start() { // Set these values before calling into the realtime database.

Check whether the writing permission was accepted or denied

阅读更多关于 Check whether the writing permission was accepted or denied

问题 I am currently trying to implement a trading system for my unity android app using firebase. For that I have to check, if a player pressed the buy button for one trade, if the selected trade is still available in the firebase database. The way it is supposed to work is, that the player who wants to buy something checks in the corresponding trade, if the buyerId is still empty, and if so puts his own id in there. I've set up the firebase rules, so that the buyerId and buyerName can only be set

问题 I'm new with unity and hololens and I started to explore it. I have a macbook (I don't know if it is a problem). I downloaded Unity with all the components (Vuforia, IL2CPP etc.). When I change project settings for the hololens development I have some problems. In particular when I check the box "Virtual Reality Supported" I don't find in the list below the Hololens option. Also if I click on "+" button. I see: Vuforia, Oculus, OpenVr but not Hololens! Furthermore also in the field:

问题 I have a Player (made out of an cylinder, some FirstCam , SecondCam and ThirdCam , for switching views when pressing a certain key - doesn't matter), which is located on a cube (wide enough to take a walk on it). There's nothing else below the cube. This is how it looks like: This is the Player 's structure: This is the inspector for Player : I have the following script ResetToInitial.cs , attached to my Player : using System.Collections; using System.Collections.Generic; using UnityEngine;

How to create game-wide object in Unity3d without singleton?

阅读更多关于 How to create game-wide object in Unity3d without singleton?

问题 Is there a way in Unity3d framework to register an object that would be accessible to all entities in all scenes in the game without resorting to singleton pattern (like a game state object)? 回答1: You could take the following approach: In the scene where the GameObject is created, in a MonoBehavior script attached to the GameObject: Name the GameObject with "name = ..." in Awake() (or in the Editor) Example: myObject.name = "FindMeInEveryScene"; Ref: https://docs.unity3d.com/ScriptReference
