MEmaster professional is a revolutionary program that enables non-programmers to produce their own interactive multimedia applications quickly and effortlessly. Applications created with MEmaster professional can have an unlimited number of windows, which users can open at the same time inside the application's desktop. Each window can contain multimedia elements of every possible type, from texts and video clips to images, 3D models, audio files and HTML pages. Guided step-by-step procedures enable you to make all of the multimedia elements active - capable of responding to a user command - and give life to complex actions, without the difficulties of having to use scripting languages. You can produce your application, composing the multimedia elements of each window and setting the properties of every element - in order to customize down to the tiniest detail - via a simple, intuitive interface. The interface features various palettes that are always shown and canvas windows that display the effects of the modifications made in real time. One of MEmaster professional's most interesting features is that it enables you to produce templates and store them in a library. Windows created using templates as a base already have all the desired multimedia elements, and just have to be customized using the contents of your choice. Templates and the windows they spawn are dynamically connected, so that (if you want) each modification to a template is automatically applied to the windows linked to it. You can publish your project in a distributable form at any time. MEmaster professional even creates application installer programs for you. Applications created with MEmaster professional can be freely distributed, without having to pay any royalties.
