- ///
- /// The derived reference counted class for a SIMD based implementation of weighted vertex deformation.
- /// Applies to both indexed and non indexed skinning.
- /// This deformer requires that the input buffers' deformable
- /// members (position, normals) be aligned as a hkVector4 (16byte aligned as it is 128bit)
- /// and for faster operation make sure that the outputs are aligned as well.
- /// N.B. It is important to note that these deformers are here to be used by Havok's demos but are not production quality.
- /// It is assumed that deforming will be done most commonly by your graphics engine, usually in hardware on GPUs or VUs.
- /// That hardware deformation is usually performed at the same time as per vertex lighting operations, so Havok cannot
- /// provide optimized deformers for all such game specific usage.
