sphereInsideFrustum(center, radius)
- Tests whether or not a sphere is inside the camera's view frustum.
- INSIDE = Sphere is inside the camera's view frustum.
- OUTSIDE = Sphere is outside the camera's view frustum.
- INTERSECT = Part of the sphere is inside the camera's view frustum. Part is outside.
center:
- Center of the sphere in World Coordinates.
- Type: float List [ x, y, z]
- Radius of the sphere
- Type: float number
Note:
- Frustum definition: A camera frustum is a truncated pyramid. It is the part that is left when the top of the pyramid is cut off and removed.
Sample Code
################## find out if the sphere is inside the view frustum
# import bge
import bge
# get current scene
scene = bge.logic.getCurrentScene()
# get a list of the cameras
camList = scene.cameras
# get camera
# my camera is named security_cam cam = camList["security_cam"]
# location of sphere center
center = [ 0.0, 0.0, 0.0]
# radius of sphere
radius = 4.5
# check if sphere is inside view frustum
sphereInside = cam.sphereInsideFrustum( center, radius)
if sphereInside == cam.INSIDE:
# your code here
if sphereInside == cam.OUTSIDE:
# your code here
if sphereInside == cam.INTERSECT:
