# 需要导入模块: import Polygon [as 别名]
# 或者: from Polygon import addContour [as 别名]
# for each contour in the jpoly
for c in contours:
# remove last redundant coordinate from each contour
# (Tangram doesn't like this - it needs the last coordinate
# to draw the last face properly)
# del c[-1]
# for each vertex
# for v in c:
# offset all verts in tile to arrange in scenespace
# this isn't necessary when the data is coming straight from the json,
# only when the data is coming from a tangram vbo
# v = [v[0]+(4096*(tilemax[0]-tile.x)), v[1]+(4096*(tilemax[1]-tile.y))]
poly.addContour(c)
# update tile's bbox with contour's bbox
t.bbox = updateBbox(t.bbox, list(poly.boundingBox()))
poly.tile = t
t.polys.append(poly)
printStatus("100%")
# make a list of all polys
# this list comprehension is the same as the nested for loops below
# neat, eh? ...but harder to read :/
# polys = [p for t in tiles for p in t.polys]
