best way to update normals?

Blitz3D Forums/Blitz3D Programming/best way to update normals?

hey, im trying to build a water system for my game, the main stuff is sorted out and working nicely. However, update normals is completely to slow to be any use with big meshs. Are there any faster ways? Ive noticed SSwift has wrote some for the code archives, are these faster or slower sswift?
