PolylightNode
(std::string const &name)¶
-
PolylightNode
(PolylightNode const&) = default¶ Use
PolylightNode
to construct a newPolylightNode
object.
-
int
compare_to
(PolylightNode const &other) const¶ Returns a number less than zero if this
PolylightNode
sorts before the other one, greater than zero if it sorts after, or zero if they are equivalent.Two
PolylightNodes
are considered equivalent if they consist of exactly the same properties Otherwise, they are different; differentPolylightNodes
will be ranked in a consistent but undefined ordering; the ordering is useful only for placing thePolylightNodes
in a sorted container like an STL set.
-
void
disable
(void)¶ Disable this light
-
void
enable
(void)¶ Enable this light
-
void
flicker_off
(void)¶ Turn flickering off
-
void
flicker_on
(void)¶ Set flickering to true so at every loop this light’s color is varied based on flicker_type
-
PN_stdfloat
get_a0
(void) const¶ Get the quadratic attenuation factor a0 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
PN_stdfloat
get_a1
(void) const¶ Get the quadratic attenuation factor a1 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
PN_stdfloat
get_a2
(void) const¶ Get the quadratic attenuation factor a2 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
Attenuation_Type
get_attenuation
(void) const¶ Get “linear” or “quadratic” attenuation type
-
static TypeHandle
get_class_type
(void)¶
-
LColor
get_color_scenegraph
(void) const¶ This differs from
get_color()
in that when applying the light color we need to make sure that a color flattening external to thePolylightNode
is not ignored.
-
Flicker_Type
get_flicker_type
(void) const¶ Returns FRANDOM or FSIN
-
PN_stdfloat
get_freq
(void) const¶ Get frequency of sin flicker
-
PN_stdfloat
get_offset
(void) const¶ Get the offset value for the random and sin flicker variations
-
PN_stdfloat
get_radius
(void) const¶ Get radius of the spherical light volume
-
PN_stdfloat
get_scale
(void) const¶ Get the scale value for the random and sin flicker variations
-
PN_stdfloat
get_step_size
(void) const¶ Get the step size for the sin function in flicker This is the increment size for the value supplied to the sin function
-
bool
is_enabled
(void) const¶ Is this light is enabled/disabled?
-
bool
is_flickering
(void) const¶ Check is this light is flickering
-
void
set_a0
(PN_stdfloat a0)¶ Set the quadratic attenuation factor a0 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
void
set_a1
(PN_stdfloat a1)¶ Set the quadratic attenuation factor a1 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
void
set_a2
(PN_stdfloat a2)¶ Set the quadratic attenuation factor a2 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
bool
set_attenuation
(PolylightNode::Attenuation_Type type)¶ Set ALINEAR or AQUADRATIC attenuation
-
void
set_color
(PN_stdfloat r, PN_stdfloat g, PN_stdfloat b)¶ Set the light’s color…
Set the light’s color… 3 floats between 0 and 1
-
bool
set_flicker_type
(PolylightNode::Flicker_Type type)¶ Flicker type can be FRANDOM or FSIN At a later point there might be a FCUSTOM Custom flicker will be a set of fix points recorded by animating the light’s intensity
-
void
set_freq
(PN_stdfloat f)¶ Set frequency of sin flicker
-
void
set_offset
(PN_stdfloat offset)¶ Set the offset value for the random and sin flicker variations… used to tweak the flicker This value is added to the variation
-
void
set_pos
(PN_stdfloat x, PN_stdfloat y, PN_stdfloat z)¶ Set this light’s position
-
void
set_radius
(PN_stdfloat r)¶ Set radius of the spherical light volume
-
void
set_scale
(PN_stdfloat scale)¶ Set the scale value for the random and sin flicker variations… used to tweak the flicker This value is multiplied with the variation
-
void
set_step_size
(PN_stdfloat step)¶ Set the step size for the sin function in flicker This is the increment size for the value supplied to the sin function
