示例1: __map_Topography
# 需要导入模块: from panda3d.core import PNMImage [as 别名]
# 或者: from panda3d.core.PNMImage import getGray [as 别名]

height_map = PNMImage()

_hu_size = height_map.getXSize()-1
_hv_size = height_map.getYSize()-1
radius = planet.radius
bottom = radius + planet.height_min

_has_sea = "sea_level" in planet.__dict__
if _has_sea:
sea_level = planet.sea_level + planet.radius
if not pts: pts = model.read("vertex")
for pt in pts:
u, v = self.__get_Pt_Uv(pt, _hu_size, _hv_size)
height_val = height_map.getGray(u, v) ## watch when extending w colours.
height = bottom + elev_range*height_val
ratio = height / radius
pt *= ratio
# If planet has sea then raise vert to sea level.
if _has_sea:
len_pt = pt.length()
if len_pt <= sea_level:
ratio = sea_level/len_pt
pt *= ratio
model.modify("vertex", pts)
