Other development tools are tools that are not necessary for web page design, but can help you in areas that you may not feel comfortable (such as WYSIWYG HTML editors that lessen the need for you to know HTML). They can also help you add that special touch to your pages and images that you might not be able to do otherwise, such as a 3d modeling program. Following are a few of these types of applications, but by no means is this all of the available development tools. Adobe PageMill - Adobe Systems Inc. (a graphical web page layout program that's been called the PageMaker of the Web) Director - Macromedia (an authoring package that let's users incorporate sound, movies, and animation in an interactive format) Shockwave - Macromedia (software that enables you to play interactive presentations, created by Director, over the web) DeBabelizer - Equilibrium (an image editing application that sometimes does a better job than Photoshop for a few operations, however there is quite a steep learning curve and little help in the way of manuals) Kai's Power Tools - MetaTools Inc. (a complement to Photoshop that enables the user to apply various effects and filters to images) Strata Studio Pro / Blitz. (a 3-D modeling and animation package - also lets users embed URLs in a 3-D image or save images in the Virtual Reality Markup Language (VRML) format used for 3-D display on the Web) Infini-D - Specular (a 3-D modeling and animation package) Ray Dream Studio - Ray Dream Inc. (a 3-D modeling and animation package - recently purchased by Fractal Corporation) GIFConverter (a shareware utility that enables you to convert images to GIF, make them interlaced, make them transparent, plus a host of other things) PhotoGIF - BoxTop Software Inc. (a shareware utility that enables you to convert images to GIF, make them interlaced, make them transparent, plus a host of other things) Fractal Dabbler - Fractal Design (a low-end version of their Fractal Design package) WebMap (a utility that enables the user to make image maps)
