bool | activateLens (int index) |
An alternate way to call set_lens_active(index, true). | |
copyLens (Lens const lens) | |
Sets up the LensNode using a copy of the indicated Lens. | |
copyLens (int index, Lens const lens) | |
Copies the indicated lens into the specified slot. | |
bool | deactivateLens (int index) |
An alternate way to call set_lens_active(index, false). | |
Lens | getLens (int index) |
Returns a pointer to the particular Lens associated with this LensNode, or NULL if there is not yet a Lens associated. | |
Lens | getLens () |
Returns a pointer to the particular Lens associated with this LensNode, or NULL if there is not yet a Lens associated. | |
bool | getLensActive (int index) |
Returns the active flag for the nth lens. | |
hideFrustum () | |
Disables the drawing of the lens's frustum to aid in visualization. | |
bool | isInView (Point3 const pos) |
Returns true if the given point is within the bounds of the lens of the LensNode (i.e. | |
bool | isInView (int index, Point3 const pos) |
Returns true if the given point is within the bounds of the lens of the LensNode (i.e. | |
setLens (Lens lens) | |
Sets up the LensNode using this particular Lens pointer. | |
setLens (int index, Lens lens) | |
Sets the indicated lens. | |
bool | setLensActive (int index, bool active) |
Sets the active flag for the nth lens. | |
showFrustum () | |
Enables the drawing of the lens's frustum to aid in visualization. | |

A node that contains a Lens.
The most important example of this kind of node is a Camera, but other kinds of nodes also contain a lens (for instance, a Spotlight).
LensNode | ( | string | name | ) |
bool activateLens | ( | int | index | ) |
An alternate way to call set_lens_active(index, true).
bool deactivateLens | ( | int | index | ) |
An alternate way to call set_lens_active(index, false).

Reimplemented from PandaNode.
Reimplemented in Spotlight, PointLight, DirectionalLight, Camera, and LightLensNode.
bool getLensActive | ( | int | index | ) |
Returns the active flag for the nth lens.
hideFrustum | ( | ) |
Disables the drawing of the lens's frustum to aid in visualization.
Returns true if the given point is within the bounds of the lens of the LensNode (i.e.
if the camera can see the point).
Returns true if the given point is within the bounds of the lens of the LensNode (i.e.
if the camera can see the point).
Sets the indicated lens.
Although a LensNode normally holds only one lens, it may optionally include multiple lenses, each with a different index number. The different lenses may be referenced by index number on the DisplayRegion. Adding a new lens automatically makes it active.
bool setLensActive | ( | int | index, |
bool | active | ||
) |
Sets the active flag for the nth lens.
When a lens is inactive, it is not used for rendering, and any DisplayRegions associated with it are implicitly inactive as well. Returns true if the flag is changed, false if it already had this value.
