George Windsor Earl the Physical Geography of South-Eastern Asia and Australia", published in 1845, described how shallow seas connected islands on the west (Sumatra, Java, etc.) with the Asian continent and with similar wildlife, and islands on the east such as New Guinea were connected to Australia and were characterised by the presence of marsupials. This formed the insipiration for Alfred Russel Wallace to propose the faunal boundary line now known as the Wallace Line. He published a paper in 1850 that invented the term 'Indu-nesians', for a quaint racial classification, derived from the Latin for India and island. He published a seminal
Intersection of a polyhedron with a line include both ends must be parallel to the given line, and do not contribute to the solution. Each of the other two subsets (if it is non-empty) contributes a single endpoint to the intersection, which may be found by intersecting the line with each of the halfplane boundary planes and choosing the intersection point that is closest to the end of the line contained by the halfspaces in the subset. This method, a variant of the Cyrus–Beck algorithm, takes time linear in the number of face planes of the input polyhedron. Alternatively, by testing the line against each of the
