Hi guys,

Why in the following example the polygon only appears while we are clicking a mouse?

;; ------------------------------------------------------------ ----------
model = obj_new('IDLgrModel')

f = filepath('people.jpg', subdir=['examples', 'data'])
ali = read_image(f)
texture = obj_new('IDLgrImage', ali)

tcoords = [[0.0, 1.0], [0.0, 0.0], [1.0, 0.0], [1.0, 1.0]]
polygon = obj_new('IDLgrPolygon', tcoords, polygons=[4, 0, 1, 2, 3], $
color=[255, 255, 255], $
texture_map=texture, texture_interp=1, $
texture_coord=tcoords)

model->add, polygon

xobjview, model
;; ------------------------------------------------------------ ----------

I don't see the logic...
Thank you in advance for you help,

nata
