A few weeks ago, my friend wanted to know how to make 3D spheres out of Photoshop, and I didn't know how to do it, but I was really interested in it, so I thought I'd try it once. So in this tutorial I'll show you how to make a nice 3D sphere, with just a few simple tools and filters, just 30 minutes, but this technique is really useful, especially for icons and logos Effect Chart: 1th Step Open Photoshop, and then use the

Enter the radius, calculate the circumference, area, sphere volume of the circle, and draw the circle.Drag bars, input boxes, and image controls to keep the data consistent!

This article describes the method of JS to realize random collision of color sphere effects. Share to everyone for your reference. The implementation method is as follows: The wants this article to help you with your JavaScript programming.

You see this picture is very familiar with, in many after Effects and 3D Max Tutorial Common, with Photoshop to do seems to be very troublesome, in fact, Photoshop launched 3D This feature has been several editions of it, from the CS3, but because the work is rarely to contact, Only know NX, today for you to bring an example of this tutorial, the entry level is very convenient. 1. Create a new document, width 600, height 340. Set the gradient tool as shown below. 2. Create a new layer, fil

This article illustrates the python implementation of the method of evenly distributing n points on the sphere. Share to everyone for your reference. The specific analysis is as follows: A recent job has encountered a need to distribute 10000 or so points evenly on a sphere. The so-called uniform, that is, the distance between the two adjacent points as far as possible consistent.My algorithm is based on t

Returns the volume of the sphere. Create a Volume class in the project, create a scanner object in the main method of the class to accept the input radius, then calculate the Spherical Volume Based on the spherical Volume formula, and output it on the console. The Code is as follows: Import java. util. principal; public class Volume {public static void main (String [] args) {// method stub automatically generated by TODO @ SuppressWarnings ("resourc

An abstract class is used in a sphere class.Zookeeper Project 3: design an abstract class CSolid, which contains two pure virtual functions to evaluate the surface area and volume. The CCube, CBall, and CCylinder classes are designed to represent cubes, sphere, and cylinder. In the main () function, define the base class pointer p (CSolid * p;), and use the p pointer to output the surface area and volume of

Create the Volume class in your project, create a scanner object in the main method of the class to accept the radius of the input, and then calculate the spherical volume based on the spherical volume formula and output it on the console.

For the newest who just entered the coin circle, lack of knowledge is a hard injury. To make achievements in the coin circle, learning and constant learning are essential, this article will share with you the content related to coin sphere terminology hedging. Let's take a look. The principle of hedging is to monitor the transaction information of each exchange through software. Once some transactions have a certain price difference on different excha
