A camera situated at the average height of human eye level (1.6 meters or 1.75 yard or 5.25 feet). <a-entity camera="userHeight: 1.6" look-controls></a-entity>

To position the camera, set the position on a wrapper . Don’t set the position directly on the camera primitive because controls will quickly override the set position: <a-entity position="0 0 5"> <a-camera></a-camera> </a-entity>

A convenient way to package your application is to write the scripts in your packages.json file and run them with the npm run command { "name": "AppName", "productName": "AppName", "version": "0.1.1", "main": ...

Mouse controls are only supported outside the VR modus and could be use for games without a HMD. For more information about mouse controls, you could find in the mouse cursor example. <a-scene> <a-entity camera look-controls mouse-cursor> </a-scene>

We can put assembly instructions inside a macro and use the macro like you would call a function. #define mov(x,y) \ { \ __asm__ ("l.cmov %0,%1,%2" : "=r" (x) : "r" (y), "r" (0x0000000F)); \ } /// some definition and assignment unsigned char sbox[...

On 32-bits systems, integers larger than PHP_INT_MAX are automatically converted to float. Outputting these as integer values (i.e. non-scientific notation) can be done with printf, using the float representation, as illustrated below: foreach ([1, 2, 3, 4, 5, 6, 9, 12] as $p) { $i = pow(1024,...

You will need to install node.js - https://nodejs.org/en/ npm install -g @angular/cli - install the CLI by executing this command in the terminal ng new projectname - after executing this command in the terminal, you will create a new sub folder titled projectname in your current folder. cd pro...

If you have: val r = Random(233) infix inline operator fun Int.rem(block: () -> Unit) { if (r.nextInt(100) < this) block() } You can write the following DSL-like code: 20 % { println("The possibility you see this message is 20%") }

Let's assume we have a search results page that displays a user's search query back to them. The code below is an example of how this could be done in PHP: Results for "<?php echo $_GET['query'] ?>" For this to work, you would access the page with a URL like: https://yoursite.te...

Plotly is a modern platform for plotting and data visualization. Useful for producing a variety of plots, especially for data sciences, Plotly is available as a library for Python, R, JavaScript, Julia and, MATLAB. It can also be used as a web application with these languages. Users can install plo...

This example illustrates how to create a simple sine curve using Matplotlib # Plotting tutorials in Python # Launching a simple plot import numpy as np import matplotlib.pyplot as plt # angle varying between 0 and 2*pi x = np.linspace(0, 2.0*np.pi, 101) y = np.sin(x) ...

In this example, we take a sine curve plot and add more features to it; namely the title, axis labels, title, axis ticks, grid and legend. # Plotting tutorials in Python # Enhancing a plot import numpy as np import matplotlib.pyplot as plt x = np.linspace(0, 2.0*np.pi, 101) y = np.sin(x) ...

In this example, a sine curve and a cosine curve are plotted in the same figure by superimposing the plots on top of each other. # Plotting tutorials in Python # Adding Multiple plots by superimposition # Good for plots sharing similar x, y limits # Using single plot command and legend import...

Similar to the previous example, here, a sine and a cosine curve are plotted on the same figure using separate plot commands. This is more Pythonic and can be used to get separate handles for each plot. # Plotting tutorials in Python # Adding Multiple plots by superimposition # Good for plots sha...
