101 Gouraud, HenriComputer display of curved surfacesThis research describes a method for producing shaped pictures of curved surfaces. It uses a small polygon approximation of the surface to solve efficiently the nidden parts detection, and then computes the shading on each polygon in such a way that visual discontinuities between adjacent polygons d...Curved surfaces; Computer display1971
102 Baehr, WolfgangCalcium-sensitive particulate guanylyl cyclase as a modulator of cAMP in olfactory receptor neuronsThe second messengers cAMP and inositol-1,4,5-triphosphate have been implicated in olfaction in various species. The odorant-induced cGMP response was investigated using cilia preparations and olfactory primary cultures. Odorants cause a delayed and sustained elevation of cGMP. A component of this c...Calcium-Binding Proteins; Nerve Tissue Proteins; Rats, Sprague-Dawley1998
