opengl and polyline width
hi,
one of my customers complained because some polygons did not show properly when zooming out (some segments did not show)
i reproduced this in odsmfcapp.
i saw that these oddbpolyline had not a null width (it was equal to 12), and showed properly only at a certain zoom level with opengl rendering (it works fine with wingdi).
as a temporary correction, i made a function that sets all widths (i really mean 'width', not lineweigh or thickness, so that there is no confusion) of oddbpolyline to 0 in order to show them a whatever zoomlevel, but i'd like to avoid this preprocessing, because some polygons are actually intended to have a width.
the other solution would be to use wingdi, but it is slower.
autocad shows these polygons with no problem.
is this a bug, is there any other solution ?
thank's for your help
