WebCis and trans double bonds are sterogenic centers in that two different compounds are possible that are stereoisomers (diasteromers). However, that is not sufficient. You must have two cumulated alkenes (c=c bonds next to each other) with at least 2 substituents to have "axial" chirality. There is also helical chirality. http://pibeta.phys.virginia.edu/docs/publications/tom_diss/html/web_diss-2.1.1.html
