Detailed Description

An infinite ray, with a specific origin and direction.

It begins at its origin and continues in one direction to infinity, and it has no radius. Useful for picking from a window, or for gravity effects.

Member Function Documentation

◆ __init__() [1/3]

__init__ ( )

Creates an invalid ray.

This isn't terribly useful; it's expected that the user will subsequently adjust the ray via set_origin()/set_direction() or set_from_lens().

◆ __init__() [2/3]

__init__ ( const LPoint3  origin,
const LVector3  direction 
)

◆ __init__() [3/3]

__init__ ( float  ox,
float  oy,
float  oz,
float  dx,
float  dy,
float  dz 
)

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getDirection()

const LVector3 getDirection ( )

◆ getOrigin()

const LPoint3 getOrigin ( )

◆ setDirection() [1/2]

setDirection ( const LVector3  direction)

◆ setDirection() [2/2]

setDirection ( float  x,
float  y,
float  z 
)

◆ setFromLens() [1/2]

bool setFromLens ( LensNode  camera,
const LPoint2  point 
)

Accepts a LensNode and a 2-d point in the range [-1,1].

Sets the CollisionRay so that it begins at the LensNode's near plane and extends to infinity, making it suitable for picking objects from the screen given a camera and a mouse location.

Returns true if the point was acceptable, false otherwise.

◆ setFromLens() [2/2]

bool setFromLens ( LensNode  camera,
float  px,
float  py 
)

Accepts a LensNode and a 2-d point in the range [-1,1].

Sets the CollisionRay so that it begins at the LensNode's near plane and extends to infinity, making it suitable for picking objects from the screen given a camera and a mouse location.

◆ setOrigin() [1/2]

setOrigin ( const LPoint3  origin)

◆ setOrigin() [2/2]

setOrigin ( float  x,
float  y,
float  z 
)
