Animation
and Hardware requirements
Hardware
requirements for animation are a Pentium, 128 Meg ram, mouse, keyboard,
soundcard, speakers, monitor, computer (grin). Numerous software
is available such as adobe and Ulead animation and video software most
will also convert from one file format to another. For
the web a frame rate of 15 fps is usually used, this is a bit jerky but
enables a 56kbps download speed to be maintained. The
animation consists of each frame being slightly different, the more
frames the better the flow with smoother animation. Macromedia: In director All cast members used for an animated colour
cursor must:
In
Windows 95, you can create cursors of either 16 by 16 pixels or 32 by 32
pixels (almost always 32 by 32 pixels, but some video cards may support
only 16 by 16 pixels).
In Windows NT, you can create cursors of 16 by 16 pixels or 32 by
32 pixels.
On the Macintosh, you can create cursors of 16 by 16 pixels. Animation Shop: Supports
several animation and video file formats. Your animations can be saved
in popular formats such as GIF, FLC, FLI, AVI, ANI or MNG. Human
Vision and animation The
human eye is "fooled" when it comes to animation. A frame rate
of 23fps and higher gives the impression to the human eye of a smooth
even flow of movement (that is if the frames are done in sequence and
correctly). A video actually consists of a series of still images,
played back at 23fps or higher gives a nice smooth even flow of
movement. If however the movie was replayed at 15fps and slower, the
movie would appear jerky, jumpy and actually irritates the eye, the
slower the fps the worse it appears. Two
Dimensional Images Create
a sense of depth by the way the lines appear they give a 2 dimensional
image in text or boxes. It is all done with lines. You can create Ripple
or Whirlpool FX using 2D filters on an image or make it to look like 3d
by adding colour , depth and shading. Vector
and Raster or bitmapped images compared Vector
drawings are created in an application such as Macromedia freehand a
vector layer is object oriented and is a graphic consisting of
mathematically described objects which usually appear as outlines with
control points, in other words a vector shape is a mathematical
description of a geometric form that includes the thickness of the line,
the fill colour, and so on. Raster
or bitmap images are created in an application such as Adobe PhotoShop.
A raster layer is pixel-oriented, When you move an object in a raster
image (or layer), you move the pixels, which affects the entire image. A
bitmap defines an image as a grid of colour pixels. It stores the colour
for each pixel in the image. A vector shape is best for a simple,
smooth, clean-looking image. It typically includes less detail, but it
can be resized without distortion. Like a bitmap, Director anti-aliases
a vector shapes against its background. A vector shape can also be
dynamically controlled with Lingo. Because a vector shape is stored as a
mathematical description, it requires less RAM and disk space than an
equivalent bitmap image and downloads faster from the Internet. Fireworks
imports vector graphics from Macromedia freehand 7, Adobe Illustrator 7,
and uncompressed CorelDraw 7 and 8. Bitmaps are best for complex and irregular images with a lot of detail at the pixel level. You can easily make minute changes to a bitmap by editing single pixels, but resizing the image can cause distortion as pixels are redistributed. Director anti-aliases a bitmap against its background, meaning that Director blends the bitmaps colours with background colours around the edges to make the edge appear smooth instead of jagged. A bitmap typically requires more RAM and disk space than a comparable vector shapes—and it can take longer to download from the Internet. formats, including GIF and JPEG
