3D Imaging and Scanning Systems and Equipment

The 3D scanning technology makes it possible to quickly and efficiently get 3D computer models of works of art and cultural heritage found in museums and churches. This data can be used for virtual presentations on the internet or for a digital catalog. The advantage of 3D models over videos and images is that the observer is able to get in reality a three-dimensional impression of the work of art. Then the 3D data can also be used to reconstruct sculptures or to make display copies to preserve the original architecture. 3D systems for scanning are extremely flexible and provide a measurement solution for a large number of applications which may include the comparison of parts and molds with CAD data. The deformation analysis and the quantification of part surface imperfections such as dents, bulges and notches can be done through the use of the various scanning systems. The equipments for inspection and measurement systems are ideal for measuring complex shapes that are otherwise too time consuming, costly, or simply impossible to measure. The 3D laser scanning systems are much faster and easier to use than traditional Coordinate Machines (CMMs).

3D Imaging can produce Animation in PAL, NTSC, SECAM Television Formats or 35mm, IMAX 70mm Film Formats and also in digital formats for CD-ROMS or Web Pages. The benefits of 3D imaging and scanning in medical science are plentiful. A new 3D computer-based motion-capture system enables physical therapists to look at the body as an integrated system almost in real time. Till now the therapists found it difficult to quantify how joint segments work together with one another after an injury. The ability to look at the body as a unified system enables one to develop more adequate treatment programs. It can also be used for prevention.

There are high-speed, multidimensional imaging system designed specifically to study the intracellular dynamics of proteins and other macromolecular complexes. They are also used for photo activation and photo conversion studies. The digital image capturing equipments are also used for the commercial survey, engineering, mining and industrial markets. These systems and equipments give better results in accuracy and precision leading to the saving of time and resources.

Rendering a 3D Model

The process of 3D rendering allows the artist to generate a picture of the model, after it has been completed. This image is created by using specific aspects of the model, such as: texture, lighting and the shading of the 3D model. The results of this rendered object will create a final product, a product that the consumer is going to be most familiar with.

3D rendering refers to the animation of giving life to a static 3D model. Through the rendering process, animations are created by using computer software to give life to the model through photo realistic techniques. 3D rendering is actually the final process of creating a 3D animation through five basic techniques.

There are two rendering techniques, real time vs. non real time. The difference between the two effective rendering techniques is the speed in which the objects are shown within the scene. Real time renderings occur at a range of twenty to one-hundred twenty frames per second, where non-real time renderings occur much slower, and are suitable for feature films, and movies.

Depending on the complexity of the model that has been created, the rendering process can be very expensive. Rendered models are often created in pieces, by different artists working for the same company, on the same production and then pieced together using graphics software.

Rendering is also used during video to calculate the final effects, or to edit the video file through the creation process. It allows the artist to view the final project, before it has been completed, creating a valuable tool in the video game and animated film design industry. Through the video rendering systems, multiple images must be created, and rendered together to create the final image, which has resulted from one 3D model. Interestingly, the films that we have become familiar with are the result of static 3D models brought through the rendering process.

The Many Features of Rendering

Within the rendering process of a 3D model, how are these models brought to life through the process of animation and then created through photo realistic techniques to become characters in the films and games that we, as consumers, have become familiar with? Through the powerful process of rendering, we can create characters, ready for film, that encompasses lifelike qualities - and here are the features that assist artists through this process.

The main qualities of rendering include: shading, texture and bump mapping, fogging, shadows, soft-shadows, reflection, transparency, refraction and reflection, depth of field, motion blur as well as non-photo realistic rendering. Although these techniques may seem confusing, once an artist has become familiar with photo realistic techniques and 3D rendering software programs, they will come to realize that it takes many of these features combined to create a successfully rendered 3D model.

Shading is an important part of a rendered model, as it gives light within the color and creates the appearance of shadows on a model, creating a lifelike appearance. It determines how the color and brightness of the surface of the model will interact with the lighting within the scene.

Texture and bump mapping give distinctive properties to the surface of the model and can create textures such as cloth, skin, or even liquid. Texture mapping is applied to surfaces on a large scale, and bump mapping to a much smaller scale, even as small as a pixel.

Fogging and shadows are both ways of playing with the light in a scene, and how it will interact with the 3D model. Fogging will create a dimming effect of the light through the atmosphere, and can create intense low-light features.

Inserting a reflection into an object allows the surface to appear mirrored, such as a surface of a window, piece of glass, or even something shiny within the scene. Transparency and translucency, all determine how light and other objects will pass through certain parts within the scene. This is also important in the creation of windows, and glass.

Determining the depth of field within the scene of a 3D model means that an object such as the character will be in motion, and aspects or scenery in the background may appear to blur. Motion blur has the same effect when high speed or motion of the camera is simulated within the rendering programs.

Objects within the scene can be changed to appear as if they have been created manually, through the use of painting or drawing. These are referred to as non-photorealistic features, as they are drastically different from the features which are most often used.

Using these effects in conjunction with each allow scenes to be set that are realistic, believable or whimsical, depending on the degree to which feature is used.

Computer Animation

Computer helps for giving artificial life to images/graphics. In advance method of animation making, computer software has a great role. Computer only can help for making 2-D and 3-D animations easily. Animation is a graphic art that is unstable, uniquely run one after another within a frame area to create an illusion of movie. Software have that feature to shape the graphics one after another in a certain frame area. After compiling the frames, it generates a compact file that shows all the frames running the images sequentially.

Computer and Animator

Computer helps the animator for designing graphics, frame settings, color compositions, compilation of files. The computer technology brings the update methods through software that helps the animator putting his enormous ideas.

Virtual Animating Synthetic Motion

Popular animation movies have many types of characters and objects. For making them, the animators should know some basic knowledge on Kenematics, Articulated figure, effectors, Geometric (key frame techniques), Physical dynamics, Behavioral in individual and as a group and Motion Control Methods (MCM) etc. In 2-D and 3-D animation work some specific functions should be used. Kinematics is the study of the time related properties of motion such as position, acceleration, velocity and independent of the underlying forces that produce the motion. Articulated figure is a structure that consists of a series of rigid links connected at joints, frequently only revolute or rotary joints in computer animation. End effector is the free end of a chain of links, for example, a hand at the end of an arm in human character.

Motion twin, time line effect, morphing, masking, blurring, expanding, transitions, transform and explode are such activities used for object motion. Frame by frame motion in certain software is the best media for character motions. You can make some action buttons, movie clips for an interactive animation.

For character (i.e. human) animation the type of information of primary importance in animating an object, especially an articulated figure is very important. For a key frame system this is the angle of each of the joints. In a forward kinematics system the motion of all the joints in character is explicitly set by the animator. The animator would move the shoulder, arm, elbow, fore arm, hand, eye and lips. In inverse kinematics the animator moves the end effector and the system computes move the corresponding positions.

Helpful Snowboarding Tips

Snowboarding is one of the more popular extreme sports and one of the trickiest ones to learn as well. It is like skiing in the fact that it is done on the snow - but instead of being able to use two poles and two different skis you are hands-free and your feet are planted on one board. It requires much more balance and skill to master.

The first thing we want to talk about is how you need to dress when you go snowboarding. Make sure that you were a helmet that is specifically for snowboarders. Make sure it fits well and does not move around on your head or sit too low on your forehead. At the same time it shouldn't be too tight.

Wearing the right type of boots is also important. Make sure that this too fit your feet well - but are not too tight. You want to be able to move around easily - but not have them fall off.

Underneath those shoes you should wear high socks. Tuck your pants into your boots. You'll find that when your boots rub against your skin all day it will rub them raw. I don't care what people say - you should never wear more then one pair of socks. It will make your boots tighter and decrease the circulation of blood that travels to your feet. This can increase your risks of frosty toes.

Snowboarding For Beginners

The first thing you need to do is figure out which foot will be your lead foot. It is common that people who are right handed will lead with their left foot or the other way around. Of course this does not always apply to everyone. If you are not quite sure which one you should lead with then you should just do what is comfortable for you.

Once you have figured it out place your lead foot into the front binding and fasten it tightly in. If you are using the step in type of board then you want to make sure that it fits in perfectly and tightly. Once the lead foot is secure place your other foot in the right position. Try to get a feel for the board by bouncing around and moving a little. Try not to fall over!

Obviously you should have someone with you who knows what they are doing so that if anything happens to you or you need any help then can assist you. Have them make sure that you put your board on right and let them lead you to the proper ski lift. Remember to get on and off the ski lift with your snowboard.

Once you have left the chairlift you will not start to go very fast down the mountain. You will be starting off on a small hill where you will be able to turn and board your way to a much larger hill. These small hills are called bunny hills or practice hills. Go to the edge of this hill. Sit down and make sure that your board is perpendicular to the hill and place your foot in the binding. Make sure that the binding is secure. You shouldn't be able to move your foot around.

Stand up and then apply pressure to your lead foot - the one in front - and bend your knees and keep your back straight. You need to feel well balanced. When you apply pressure make sure that you and not leaning your body. Just pressing your feet firmly to the ground. Now you are ready to take off. Just remember that you are a beginner and you are going to fall down a few times before you get it right.

Reminders For Snowboarders

Please remember to follow any safety instructions that your trainer has told you. You also need to make sure that you have the proper snowboarding equipment before you hit the slopes. To make sure you have done this ask a clerk at the store which one would be best for you (a beginner) to use.

There are many different extreme sports and each one is unique and different in its own way. Xtreme Sports is dedicated to teaching people about the different sports. They provide news and the latest races and competitions and tips to teach you how to learn the one of your choice.
