hi song i really really wanna thank you for the help u gave me…

i hope i won’t bother you again but i wanna have an information if you know…

i saw that in the instrutcion:

gluTessVertex(tess, v1[i], v1[i]);

v1[][] is a matrix with the vertex of my polygon

i have a struct to memorize my vertex for polygon…i mean i have a matrix: each row is a polygon. for example i define my vertex in this way matrix[0][0].x and matrix[0][0].y for the first vertex…

i saw that glutessVertex wants a double vector… is it possible put a struct or i have in any way put a vector in that instruction…

thanks!!
