Webelement , called the trilinear hexahedron [19]–[24], along with the visible coordinate lines. It is determined solely by interpolation points—its eight vertices. Its edges and all coordinate lines are straight, whereas its sides, so-called bilinear quadrilateral surfaces [23]–[25], are somewhat curved (inflexed). WebMay 4, 2024 · 1 Answer. Let A i ( x i, y i, z i) T ( 0 ≤ i ≤ 7) the 8 vertices of the hexahedron with their 3D coordinates (we don't need the 4th projective coordinate). I don't need to assume that the hexahedron is a regular pyramid frutrum. If the unit cube is defined by …
