Research on Six Degrees of Freedom elastic constraints of BulletResearch on Six Degrees of Freedom elastic constraints of Bullet During this time, I planned to integrate the physical engine, so I did some research on the open-source physical engine Bullet. The Bullet research has been around for a while. The Bullet engine has been in touch for a long time, but it has been just an example of running it, and there are no research examples and source code, if you want to integrate it into the rende

Kiki want to surround all the trees with the minimal required length of the rope. As follow, To do this problem more simple, consider all the trees is circles in a plate. The diameter of the trees is the same (

the drill reaches the fire. Type 2: double Classic Drilling MethodThe other steps are the same as the first method. The difference is that two people work together this time. One person uses a wood lid with a groove to fix the drill shaft on the drill plate. The other person uses a rope or rattan with a large friction to wrap a few laps on the drill shaft and then pull it b

film on the plate to prevent water loss. after heating, the plate will be very hot. We often use special microwave gloves to take it. however, vegetable soup often gets dirty gloves with a rag. today, we will introduce a simple method: When you wrap the fresh-keeping film, leave two sides instead of the Bag. When you take them out, the two sides will not be hot. 26. It's hard to take your shoelaces away The shoelaces of sports shoes are easy to relax and bring a lot of trouble to people.

Title DescriptionThere are n heavy weights, each of which is tied to a rope long enough. Each rope goes from top to bottom through a hole in the table and then ties together. In the figure x is the common knot. Assuming that the rope is fully elastic (without causing energy loss), the table is high enough (so that the weight does not drop to the ground) and ignor

Samir returned home from the contest and got angry after seeing his hostel dusty. Who likes to see a dusty, after a brain storming programming contest? After checking a bit he found a brush in the his class which has width W. dusts is defined as 2D points. And since they is scattered everywhere, the Samir is a bit confused. He asked Samee and found his idea. So, he attached a rope with the brush such that it can is moved horizontally (in X axis) with

After the long contest, Samee returned home and got angry after seeing his hostel dusty. Who likes to see a dusty, after a brain storming programming contest?

Problem Description There is a lot of trees in HDU. Kiki want to surround all the trees with the minimal required length of the rope. As follow, To do this problem more simple, consider all the trees is circles in a plate. The diameter of the trees is the same (the diameter of a tree is 1 unit). Kiki can calculate the minimal length of the rope, because it ' s so easy for this smart girl. But we don ' t h

. The shortcut keys for the "Charms" setting feature are: Win+i. Figure 1 Opening the computer settings The General tab in the computer Settings Panel has two main tools: "Recover your computer without affecting your files" and "Initialize the computer and start over", which are the two leading actors involved in our test today. Let's try the "restore the computer without affecting your files" feature first. Figure 2 General Tab Before we proceed, we'll do

C # language and database "broken-rope"　　In the course of my progress. The first phase of the study is the Java Foundation, although now to C # is still the foundation! But!After a lapse of two months today, again picked up the book to see, the mind of Java in the knowledge of only a few fragments! so long-term learning experience let me come to a conclusion: if you are not a genius, really is to go through continuous effortsTo reach the point where t

But the way of open-drain can be realized by line and logic to achieve quasi-bidirectional io, which is not push-pull.Floating empty, as the name implies is suspended in the air, the above with a rope pull up, the following with a rope to sink down. Pull up, pull down the settings are mainly to see

Concept Introduction:Factory method Mode: Please read the simple Factory mode before learning the factory method modeThe factory method pattern is intended to define a factory interface that creates product objects, deferring actual creation to subclasses.Factory method mode is a further abstraction and generalization of the simple factory modelSeveral required objects of the factory method pattern:1. Abstract Factory2, the specific factory: the implementation of the abstract factory interface l
