      • setBonesAsMatrices

        public void setBonesAsMatrices​(@NonNull
                               Engine engine,
                               @NonNull
                               java.nio.Buffer matrices,
                               @IntRange(from=0L,to=255L)
                               int boneCount,
                               @IntRange(from=0L)
                               int offset)
        Updates the bone transforms in the range [offset, offset + boneCount).
        Parameters:
        engine - Engine instance
        matrices - A FloatBuffer containing boneCount 4x4 packed matrices (i.e. 16 floats each matrix and no gap between matrices)
        boneCount - Number of bones to set
        offset - Index of the first bone to set

      • setBonesAsQuaternions

        public void setBonesAsQuaternions​(@NonNull
                                  Engine engine,
                                  @NonNull
                                  java.nio.Buffer quaternions,
                                  @IntRange(from=0L,to=255L)
                                  int boneCount,
                                  @IntRange(from=0L)
                                  int offset)
        Updates the bone transforms in the range [offset, offset + boneCount).
        Parameters:
        engine - Engine instance
        quaternions - A FloatBuffer containing boneCount transforms. Each transform consists of 8 float. float 0 to 3 encode a unit quaternion w+ix+jy+kz stored as x,y,z,w. float 4 to 7 encode a translation stored as x,y,z,1.
        boneCount - Number of bones to set
        offset - Index of the first bone to set

        public int getBoneCount()
        Returns:
        number of bones in this SkinningBuffer
