EVS has two distinctly different animation concepts. Our traditional animations consist of a sequence of bitmap images that have been encoded into an animation file (AVI, MPG, or HAV) using one of several different CODECS. This type of animation has some distinct advantages including the ability to include a soundtrack (background music and/or narration) and the animations are playable with a variety of common and (usually) free players.
C Tech also offers a second animation concept that we refer to as 4DIM, or Four-Dimensional Interactive Model Animations. The name 4DIM (referring to four dimensions instead of only 3) was chosen because these models represent a 3D scene changing in time (the fourth dimension). Unlike bitmap (image) based animations 4DIMs contain a complete 3D model at each frame of the animation. Each frame can be thought of as a VRML model (though it is not) and has similar functionality. Each frame of the model can be zoomed, panned and rotated as a static 3D model or you can interact with the 4DIM animation as it is playing.
The 4DIM Player is offered as a module (Playback_4DIM) in all versions of our software and as a stand-alone application.
The 4DIM files (which have a .4d suffix) created by EVS-PRO must be played back in a licensed copy of C Tech software or a licensed 4DIM Player (standalone). 4DIM Files created in MVS automatically contain a password that allows them to be played with a demo player. In other words, 4DIM files created in MVS can be played on free players.
