Using p5.sound.js in instance mode: 'p5.Amplitude() not a constructor'

阅读更多关于 Using p5.sound.js in instance mode: 'p5.Amplitude() not a constructor'

问题 I am using an npm, webpack, babel environment to write an application with p5.js. To be able to have the sketch as a module, I have the sketch in instance mode and import the library and add-ons as modules: import p5 from 'p5'; import 'p5/lib/addons/p5.sound'; import 'p5/lib/addons/p5.dom'; Then I load them to the window inside my sketch: const sketch = (p5) => { window.p5 = p5; ... } new p5(sketch); When I try to use: amp = new p5.Amplitude() I get a 'p5.Amplitude is not a constructor' error

Graphics processing architecture employing a unified shader

阅读更多关于 Graphics processing architecture employing a unified shader

FIELD OF THE INVENTION The present invention generally relates to graphics processors and, more particularly, to a graphics processor architecture employing a single shader. BACKGROUND OF THE INVENTION In computer graphics applications, complex shapes and structures are formed through the sampling, interconnection and rendering of more simple objects, referred to as primitives. An example of such a primitive is a triangle, or other suitable polygon. These primitives, in turn, are formed by the interconnection of individual pixels. Color and texture are then applied to the individual pixels

Processing教程：如何使用Kinect V2做交互设计 - Hello World

做体感设计，从巨硬家的K设备入门是一个非常便捷的渠道。需要准备： 1、Kinect for Windows v2 (K4W2) 一台 2、Kinect SDK v2 一台 3、带USB 3.0接口的Win10 4、Processing 3.0 5、最新的N卡驱动（我这里是2080ti） 6、DirectX 11 然后就可以开始测试了。共有三步： 1、下载并安装Kinect v2 for Processing库 2、接好Kinect v2 3、在Processing中运行HelloWorld Processing的HelloWorld需要自己写，很简单，共3步： 1、引用库并声明1个Kinect实例 import KinectPV2.*; KinectPV2 kinect; 2、在setup中对齐进行初始化 size(1920, 1080); kinect = new KinectPV2(this); kinect.enableColorImg(true); kinect.init(); 3、在draw中显示实时画面 background(0); image(kinect.getColorImage(), 0, 0, 1920, 1080); fill(255, 0, 0); text(frameRate, 50, 50); 如果一切正常，此时你就可以看见Kinect的画面了。

CreateFont() from String

问题 It is posible to make a variable in Processing or Java that self contain the typography (ttf or otf) in format of String to be able to load it in the same way that you can do it with images, since LoadImage () works from an array of integers. I can do it with the Images. Is there any way to do it for the case of typography? Thanks! int[][] var = { // R G B A {255, 0, 0, 128}, { 0, 255, 0, 128} }; PImage loadPixelsArray(int xDiv, int yDiv, float[][] dots) { PImage img = createImage(xDiv, yDiv,

3 月，跳不动了？>>> 1 使用eclipse编写processing程序 1.1 预备说明 2015-08-11 22:25:23 本地环境: mac,jdk8,processing2.2 本文使用mac作测试，在linux和win下也差不到哪去，原理一致参考文章 https://processing.org/tutorials/eclipse/ Processing in Eclipse 1.2 找到processing的jar包在mac系统上安装了processing,在程序上点击右键->show package Contents(显示包内容) 打开后是这样的其中的jar包是我们需要的，我们可以把他们拷贝出来 1.3 导入jar包到eclipse 接下来是在eclipse中导入我们需要的jar包，在eclipse中依次选择File->import->file system->选择jar包所在目录，选择我们所需的jar包,这里我们只选择core.jar,点击finish继续接着右击刚才导入的core.jar -> build path -> add to build path,将导入的jar放到build path中 1.4 在eclipse下编写processing程序现在我们可以使用eclipse编写processing程序了 // test.java

ELEC4620/7462 Digital Signal Processing Assignment 3 (Due Date: Monday 16/09/2019 at 5pm) 1. We wish to extract tones at 150 and 250 Hz from tones at 1050 and 1150 Hz and then downsample the output by the largest possible factor. Assume the signal containing the four tones is sampled at 40 kHz. Use a Kaiser window FIR filter with a passband from 0 to 300Hz (3 dB down at band edge) and attenuation > 80 dB at 500 Hz. Implement the filter, maximally downsample the output, and examine the output spectrum to ensure that it meets specifications. Now reimplement the filtering and downsampling with a
