A visualization model early in the development of a 3D application, is a mechanism to make architectural or design decisions to avoid risks by developing, supporting and complementing the rapid prototyping process. In this sense the article is shown into support the work of developer of interactive applications through a 3D visualization tool that builds your character early in the environmental conditions to allow the automatic translation to a rapid prototyping framework. To achieve this end, shows the use of conditional InTml framework with tools for recording, playback and event simulation to rescue information on the use of the application. Finally it gives details of the implementation and testing of prototypes.
