Three Types of Expressions in Laser Scanning 3D Modelling By Steven Michaels

• Modern day technologies have enabled man to translate his physical world into digitized data. An example of which is the ability of 3D laser scanning to convert scanned information into data models which can be built, rebuilt, edited and transformed using the computer.
• In fact, laser scanning is helping mankind to further advance our knowledge about the world around us. Through it, the police are able to recreate crime scenes and solve cases which used to be too elusive due to limited evidences. In the engineering field, laser scanning has given way for troubleshooting structural problems before they can even occur. This technology has also helped us to preserve our heritage; by reverse engineering, we are able to recreate damaged objects and structures which define our history on this planet.
• The converted digitized data is called a "data expression." There are three kinds of "expressions" used in the industry nowadays. These are: the polygon mesh, surface expression and the solid CAD.
• 1. The Polygon Mesh
• This expression is primarily based from a conceptual point of view. That is, through a series of brainstorming and discussions, a specific concept is created and this concept is given life through the polygon mesh. The mesh is nothing but an abstraction of simple curved pieces and these pieces are the foundations of the digitized concept. The weak point of the polygon mesh is that once it is already created, it cannot be edited or altered ever again. The resulting mesh represents the exact actual thing that will be manufactured.
• 2. Surface Expression
• This type of expression is best used for creating organic shapes and other artistic pursuits in 2D. Surface expression allows for the alteration of the object's surface; these alterations can be done without limitations unlike the polygon mesh. However, the objects cannot be manufactured directly using the surface expression model alone. This is the reason why it is usually just used to model objects which are small or medium.
• 3. Solid CAD
• The main difference of this type of expression from the two given above is its ability to integrate a model's readiness to be manufactured into the actual object and its flexibility to immediate changes. This is the model frequently used by engineering firms as this allows for the constant evaluation of the defects and problems that might arise during the construction of the object. This is usually used for building structures intended for public and commercial use.
• Prior to the development of 3D modelling using data obtained from laser scanning, engineering and construction firms have to settle for the more expensive and time-consuming methods like 3D reconstruction using drawings which are manually made. These traditional methods can also leave out small details which might prove to be dangerous in the future.

Reasons Behind The Continuing Need For Income Protection Insurance By Dawie Bester

• Recent years have seen an increase in the continuing need for income protection insurance. Income protection insurance is an insurance policy that allows a person to receive monetary benefits when he or she is unable to go to work due to a natural illness or an unforeseen accident. Who needs this type of policy then?
• Majority of today's working class are now in their forty's to nearing retirement. This means that most of these people are now prone to falling ill or sick, or having health condition that could render them incompetent for their regular work. There was a time when people would ignore health insurance policies because they thought that they would be throwing away their money for nothing. Today however, the natural risk of sickness and accidents prove that there is sense behind such need.
• There are many people who have come to realize the need for financial support when they are retired and no longer able to work for a regular income. Those in their thirties have opened their minds and wallets to retirement plans or pension benefits which give a regular monthly check about twenty to thirty-five years from now. So why should there be no need for an insurance policy that allows a person to receive benefits in the near future?
• The difference between a pension plan and an income protection insurance is that people believe that getting old and retirement are an inevitable part of life. On the contrary, getting sick or being in an accident that could rob us of the ability to work is hardly on our minds. Having that income insurance will allow us to receive at least a portion of our regular salaries, come the time when we are not able to properly perform our jobs.
• Income protection insurance could be the primary choice for making sure that your life can still go on even if you physically cannot. It can provide up to 75% of the regular gross income until the policyholder recovers and can once again perform the duties for the job. If there are mortgages or loans to be paid, or the regular monthly expenses that need to be taken care of, the availability of income insurance can be the thing that saves you if you run into an accident or fall ill. Hardly any other insurance policy can offer the same assurance, as most policies fall well below what the policyholder regularly earns.
• If the idea of falling sick or being involved in an accident is too far-fetched to imagine, here are some facts and numbers that support that there is indeed a need.
• 2.63 Million people live off state benefits due to their inability to work. This includes those who are physically disabled, possibly due to injuries, or health issues that deem them unfit to work.
• 75% drop in regular income if a normal person is to live off state benefits. This means that only 25% of the regular income is being covered by the state policies that so many people rely on.
• 17 days is the time period that a person can live off of what they have if there is no longer any income available
• 33% of people believe they can live on only 35% of what they currently earn per month. This is still not covered by the regular state benefits which provide for only 25% of a person's monthly income.
