We shall interrupt the history of projective geometry . 我们要把射影几何的历史断开。
The synthetic geometers were developing projective geometry . 综合几何学家们在发展射影几何学。
Hermann kankel did not hesitate to say in 1896 that projective geometry is the royal road to all mathematics . HermannKankel在1896年毫不犹疑地说,射影几何是走向所有数学的康庄大道。
Then projective texture divides are not available ,则投影纹理分隔将不可用。
If projective texture divides are available ; otherwise , 如果投影纹理分隔可用,则为
