value
|
The bounding sphere. |
Is this a planetary world?
property

IsPlanetary
{
get
}
|
||
type
|
bool
|
||
value
|
true
if
this
world
is
planetary
(e.g.
based
on
an
ellipsoid),
false
if
this
world
has
somt
other
base
geometry
(e.g.
a
rectangular
patch).
|
Ensures that the given point has a minimum distance to the world.
method
|
Clamp
(Vec3D point,
float64 distance = 0)
|
||
type
|
Vec3D
|
||
params
|
point
|
The point in world-space. | |
distance
|
The
minimum
distance,
in
world-space.
Defaults
to
0 . |
||
returns
|
The updated point. |
Remarks:
The implementing method is free to choose a minimum distance that is larger then the given distance parameter.
Computes the distance to the given point.

params
|
point
|
The point in world-space. | |
returns
|
The
distance
from
point
to
the
nearest
world
feature
or
0
if
the
world
is
empty.
|
Picks the nearest feature in world-space that intersects with the given ray.

Output for picked point. | ||
up
|
Output for world-specific up-direction at point. | ||
normal
|
Output for surface normal vector at point. | ||
returns
|
true
if
a

been
picked,
false
if
not
(point,
