kinect/ processing / simple openni - point cloud data not being output properly

由 空扰寡人 提交于 2019-12-30 05:29:13
问题 I've created a processing sketch which saves each frame of point cloud data from the kinect to a text file, where each line of the file is a point (or vertex) that the kinect has registered. I plan to pull the data into a 3d program to visualize the animation in 3d space and apply various effects. The problem is, when I do this, the first frame seems proper, and the rest of the frames seem to be spitting out what looks like the first image, plus a bunch of random noise. This is my code, in

Using Processing on a server to create images behind the scenes

由 China☆狼群 提交于 2019-12-29 05:33:09
问题 The way I see most people use Processing is for drawing an image directly onto a screen or webpage on the client side. How would one use Processing to create an image without a visual canvas, then save this image to a file? Here are the specific steps I'm interested in: Someone visits a webpage, which causes the Processing program to start running The Processing program would work behind the scenes to create an image, then save it to a known filename The webpage would load the known filename

FFmpeg - Overlay one video onto another video?

由 北城以北 提交于 2019-12-29 01:34:28
问题 I understand that this is a very open ended question. I have done some initial reading into FFmpeg, but now require some guidance. Problem I have a video input.mov . I would like to overlay another video on top of overlay.wov . The result should be a single video ( output.mov ). Notes Done some initial reading into FFmpeg and read this question. Thanks - C. Edits Backend is Go/Ruby. Open to using a new language. The audio from the first video should be kept. Setting the interval at which the

Equivalent of C# anonymous methods in Java?

由 霸气de小男生 提交于 2019-12-27 22:09:24
问题 In C# you can define delegates anonymously (even though they are nothing more than syntactic sugar). For example, I can do this: public string DoSomething(Func<string, string> someDelegate) { // Do something involving someDelegate(string s) } DoSomething(delegate(string s){ return s += "asd"; }); DoSomething(delegate(string s){ return s.Reverse(); }); Is it possible to pass code like this in Java? I'm using the processing framework, which has a quite old version of Java (it doesn't have

How to form a shape out of horizontal line grid? With Processing?

由 谁说我不能喝 提交于 2019-12-25 18:57:20
问题 I was wondering how to achieve a similar effect like the shape of the letter "A" coming out of a horizontal line grid (see picture attached). Does somebody know how to find a tutorial? How is this technique called? Can you do it with Processing? Or do you need a 3D program? Any hint is very welcome! 回答1: Imagine extruding a blurred white A shape on a black background, a height map if you will. In Processing you'd loop through each pixel in the image and map the brightness of each pixel to the

Translated grapple physics from Processing to Unity to get different results

由 人盡茶涼 提交于 2019-12-25 17:16:00
问题 tl;dr Moving my game from Processing to Unity. Code responsible for grappling by manually changing the player's velocity doesn't work even though it's basically copy/pasted. Hi, I've been working on a project of mine over the summer on Processing, and last week I decided to translate it over to Unity. What I'm having a problem with is the grapple/rope physics. It's supposed to essentially keep the player inside a circle (made by the endpoint of the rope and the length of the rope). When the

Asterisk 1.8 sip 协议栈分析

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 引用自：http://blog.csdn.net/z1623866465/archive/2011/01/02/6113057.aspx 看了一下 asterisk 1.8 ，chan_sip 更新了许多内容，下面结合asterisk 1.4 asterisk 1.6 分析一下sip协议栈。 此笔记为本人学习记录，有些地方描述其他人可能看不懂，望见谅。 分析路线 sipsock_read->parse_request->find_call->handle_inconming->handle_request_方法名。。。。 协议栈初始化：load_module() 函数加载SIP配置信息，解析sip.conf挂载到全局变量中。 首先初始化user,peer,register全局链表（1.6 版本中已经改为hash存储 估计性能提高不少），这三个链表分别存储用户，peer,register三个实体。 接下来创建 调度器，IO管理器，这里IO即监听socket fd句柄上的IO事件，chan_sip用poll异步IO实现此功能，io_context 结构封装了此功能。 创建IO调度器后注册各种app， load_module（）最后调用restart_monitor()函数创建一个线程（do_monitor()

Continuous image loading/processing & display on button click (in Swing)

问题 I have trouble with continuous image loading&processing&display in Swing: Below there is simple case where clicking a button causes my program to grab frame from webcam and then display this picture in jlabel. It works as it should, but i have to consecutively click this "Start" button in order to get new image(frame) shown. private void StartActionPerformed(java.awt.event.ActionEvent evt) { displayed_img = this.getPIC_COLOR(player); img_field.setIcon(new ImageIcon(displayed_img)); } Im more
