A .CAF file typically refers to a “Cal3D Binary Animation File.” Cal3D is an open-source 3D character animation library often used in video game development and other interactive 3D applications. These “.caf” files are specifically designed to store binary animation data for characters or objects created using Cal3D framework.
CAF files play a crucial role in imparting realistic human-like movements to characters. They define animations for various actions such as walking, running or any other dynamic actions that character might perform. Cal3D animations can also be represented in an XML format, using files with a “.xaf” extension. This XML representation provides an alternative way to store and manipulate animation data within Cal3D.
Cal3D Binary Animation File
Here is some information about what you might find in a Cal3D Binary Animation File:
Animation Data: .caf files primarily contain animation data such as skeletal animations, keyframes, bone transformations and other information related to character or object animations.
Skeletal Information: Cal3D animations are typically based on a skeletal hierarchy where bones are used to deform character’s mesh. The .caf file stores information about bone hierarchy and transformations for each keyframe.
Keyframes: Animation in Cal3D is typically stored as a series of keyframes. The .caf file will contain data for each keyframe, including positions and orientations of bones at those keyframes.
Blend Weights and Poses: In more advanced animations, .caf files may also contain information about blending different animations together and defining different poses for characters.
Compression: To reduce file size and optimize performance, .caf files may employ compression techniques to store animation data efficiently.
