+
+Parsing a 3D model file and understand the different links between bone matrices,
+keyframes and vertices is a task that can take a lot of time and motivation of
+the developer. On top of that, combining the different bone transform matrices
+for the current frame is often error prone.
+
+[rib] is an attempt to tackle these problems and
+might help you save time.
+
+Current features of [rib] include:
+
+- Support of collada files coming from the latest Blender version.
+- Precomputation of the bone matrices expressed in the world space so that you
+  just have to pass it to your shader for traditional GPU skinning.
+- Interpolation between keyframes
+- (De)/serialization in binary thanks to [bincode]
+
+[rib] can be greatly extended, for example with the support of other format
+handling skeleton data, such as the [glTF] format.
+Contributions are more than welcome.
