以下是使用panda3d计算任意一个点是否在指定范围内的完整代码:
from panda3d.core import Point3, BoundingBox
# 定义8个长方体顶点
vertices = [[19.0, 1.0000016689300537, 0.0],
[-10.0, 0.9999991059303284, 0.0],
[-10.0, 0.9999991059303284, 24.0],
[19.00030517578125, 1.0349067449569702, 24.0],
[19.0, -0.9999983310699463, 0.0],
[-10.0, -1.0000008344650269, 0.0],
[-10.0, -1.0000008344650269, 24.0],
[19.00030517578125, -0.9650932550430298, 24.0]]
# 创建包围盒对象
bbox = BoundingBox(Point3(*vertices[0]), Point3(*vertices[0]))
# 扩展包围盒对象
for vertex in vertices[1:]:
bbox.extendBy(Point3(*vertex))
# 判断一个点是否在包围盒内
point = Point3(0, 0, 0)
if bbox.contains(point):
print("The point is inside the bounding box.")
else:
print("The point is outside the bounding box.")
代码中,我们首先使用panda3d的Point3和BoundingBox类定义了8个长方体顶点和包围盒对象。然后,我们使用extendBy()方法扩展包围盒对象以包含所有顶点。最后,我们使用contains()方法判断指定点是否在包围盒内
