Patent ID: 7940270

Claim:
A method of processing source data (D S ) into target data (D T ), comprising: dividing, the source data(D S ) into a number data blocks (B 1 , B 2 , B 3 , B 4 ) each block representing an information space having, at least two dimensions, the blocks (B 1 , B 2 , B 3 , B 4 ) being delimited by a respective set of block edges (b 1 , b 2 , b 3 , b 4 ), the blocks (B 1 , B 2 , B 3 , B 4 ) having at least two selectable resolution levels (r 0 , r 1 , r 2 , r 3 ); selecting the resolution levels individually based on a level-of-detail scheme such that different blocks represent information at different resolution levels, characterized by, a block sample boundary (β SB ) around each block (B 1 , B 2 , B 3 , B 4 ) being defined by a set of surfaces spanned by at least one sample which in each respective dimension (r, s, t) of the information space is positioned a longest distance from a geometric ( 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ) point of this block, a rim distance (δ 4 ) between the block sample boundary (β SB4 ) and the block edge (b 4 ) being relatively short for a comparatively high resolution level (r 3 ), the rim distance (δ 1 ) being relatively long for a comparatively low resolution level (r 0 ); and determining at least one interpolation parameter (ρ SI , e(ρ SI )) for at least one interpolated sample between a first block (B 2 ) neighboring a second block (B 3 ) at least based on a first rim distance (δ 2 ) of the first block (B 2 ) and a second rim distance (δ 3 ) of the second block (B 3 ).
