Definition of Entropion. Entropion is the inversion, or rolling inward, of all or part of the edge of an eyelid, which causes the hair-bearing part of the lid to come into contact with the outside of the eyeball. This creates friction, irritation and discomfort and can severely damage the eye. Entropion has a strong genetic component and often is present at birth due to a hereditary abnormality in the dogâs facial structure. It is much more common in breeds with flat faces, short muzzles and heavy facial skin folds. It can also be acquired as a result of trauma, inflammation or infection and from skin laxity associated with aging. Entropion usually â but not always-occurs in both eyes.
Explore Different Types of Animation. At the broadest sense, there are 3 types of animation: 2D, 3D and Stop Motion. Any way to manipulate a sequence of images, frame by frame, is considered a Type of Animation. Animations usually fall into one of these three categories - 2D, 3D or Stopmotion. The boundaries between them are, however, blending with great speed.
Flash supports the following types of animation: Motion tweens Use motion tweens to set properties for an object, such as position and alpha transparency in one frame and again in another frame. Flash then interpolates the property values of the frames in between. Motion tweens are useful for animation that consists of continuous motion or transformation of an object. Motion tweens appear in the Timeline as a contiguous span of frames that can be selected as a single object by default. Motion tweens are powerful and simple to create. Classic tweens Classic tweens are like motion tweens, but are more complex to
