Animation Tips and Tricks

Animation is all the rage on the web and is becoming more popular every day. But before you begin to create animations for your web site, you need to consider some basic questions, such as: 3D Models What is its purpose? What kind of audience do you want to attract? What are you trying to say/promote? Will the animation add interest to your site or detract from it? If you've decided that having an animation will add value and interest to your site, we move onto other considerations, which include file formats and size, along with design and execution.

When looking at the available image and animation formats, here are a few things to keep in mind. JPEG, 3D Models (Joint Photographic Experts Group) is a 24-bit file format and is the overall best choice for compressing photographs, naturalistic artwork, grayscale images and similar material. As a JPEG file is compressed, it discards data and is referred to as a "lossy" format. Repeated saving discards more data and can cause "artifacts," where portions of the image begin to clump together.

GIF, (Graphic Interchange Format) is the format of choice to compress lettering, simple cartoons, and line drawings. GIF images are often made up of Vector graphics, such as lines and curves, which are mathematically defined, so they produce a high quality result, no matter how much they are scaled, but a GIF is a bitmap format, so the scaling options don't apply. GIF files are often composed of few colors and compress well. Other common animation formats are AVI (Audio-Video Interleaved - a desktop video movie format from Microsoft), MPEG (Moving Picture Experts Group), MOV (Quicktime), SWF (the Flash Player format) and Shockwave.

When using image maps in 3D Models, file formats to consider are: JPEG and GIF as above, as well as TIFF (Tagged Image Format), TGA (Targa, by Truevision) and PNG (Portable Network Graphics). PNG is worth noting because it offers a 48-bit true color setting and a 16-bit grayscale setting. One advantage is that PNG is lossless, meaning that no matter how many times you save the file, you will not lose data. This is important for maintaining high-quality images. Another factor favoring PNG is gamma correction, a setting used by many image manipulation programs to measure brightness and contrast levels. PNG automatically adjusts the gamma setting and makes sure that images look correct across platforms.
