![]() ![]() ![]() If the window moves in a backward direction, then the object appear to move in the forward direction and the window moves in forward direction then the object appear to move in a backward direction.ĥ. In which direction the fixed sized window moves, the object appears to move in the opposite direction as shown in fig: In computer graphics, Panning relates to the movement of fixed size window across the window object in a scene. Panning: Usually Panning refers to rotation of the camera in horizontal Plane. This function is popular in the film industry.Ĥ. Tweening: Tweening is the short form of 'inbetweening.' Tweening is the process of generating intermediate frames between the initial & last final images. It distorts only the initial images so that it matches with final images and no fade occurs in this function.ģ. Wrapping: Wrapping function is similar to morphing function. In the third step, the key point of the first image transforms to a corresponding key point of the second image as shown in 3 rd object of the figure.Ģ. The second step involves the selection of key points on both the images for a smooth transition between two images as shown in 2 nd object.ģ.In the first step, one initial image and other final image are added to morphing application as shown in fig: I st & 4 th object consider as key frames.The process of Morphing involves three steps: This function is commonly used in movies, cartoons, advertisement, and computer games. It is one of the most complicated transformations. Morphing: Morphing is an animation function which is used to transform object shape from one form to another is called Morphing. Vector illustrations are great for logos, illustrations/artwork, animations, and text.1. Typically vector art is created in illustration applications such as Adobe Illustrator or CorelDRAW. All Microsoft Office clipart uses vector art and most charts and graphs produced by Office or by statistical analysis software are vector-based. So, what types of graphics would typically be vector? Well, almost all computer font files are based on vector images of the letters - that's why it's possible to scale them WAY up or WAY down and still have the letters be clear. If you want to make the circle bigger, you just increase the value of r - instead of having to keep track of tons more pixels, the computer just has to keep track of a different number. If you remember back to your high school geometry, the equation for a circle of center ( h, k) and radius r is (x - h) 2 + (y - k) 2 = r 2. One of the greatest things about vector images is that you can re-size them infinitely larger or smaller, and they will still print out just as clearly, with no increase (or decrease) in file size. Generally speaking, vector images are made up of paths or line art that can infinitely scalable because they work based on algorithms rather than pixels. Instead of trying to keep track of the millions of tiny pixels in a raster image, vector images keep track of points and the equations for the lines that connect them. This is a common problem but can be remedied by using raster image editing programs such as Photoshop to change resolution and properly scale images.Ĭommon Raster Image Types: JPG, TIFF, GIF, PNG, BMP ![]() This is because we are stretching the pixels over a larger area, thus making them look less sharp. As you may have guessed, the more pixels in the image and the higher the resolution is, the higher quality the image will be.įor example, if we scale a raster image to enlarge it, without changing resolution, it will lose quality and look blurry or pixilated. ![]() The number of pixels that make up an image as well as how many of those pixels are displayed per inch, both determine the quality of an image. Since raster images are pixel based, they are resolution dependent. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image. These are the types of images that are produced when scanning or photographing an object. Raster (or bitmap) images are generally what you think about when thinking of images. ![]()
