Detailed Description

LightOp defines a 3D light.

Member Function Documentation

lightOp() [1/2]

const LightOp * DD::Image::LightOp::lightOp ( ) const

inlineoverridevirtual

Cast to a LightOp. This is much cheaper and safer than using dynamic_cast.

Reimplemented from DD::Image::Op.

Referenced by getLightOpAt().

lightOp() [2/2]

LightOp * DD::Image::LightOp::lightOp ( )

inlineoverridevirtual

Reimplemented from DD::Image::Op.

node_color()

unsigned DD::Image::LightOp::node_color ( ) const

inlineoverridevirtual

Set the default color of a light node.

Reimplemented from DD::Image::CameraOp.

isDeltaLight()

virtual bool DD::Image::LightOp::isDeltaLight ( ) const

inlinevirtual

Whether the light has a delta shaped distribution (point/spot/direct lights) Must implement.

coneAngle()

virtual double DD::Image::LightOp::coneAngle ( ) const

inlinevirtual

Cone angle is the half-angle (radius) of the code, so the default 90.0 value describes a 180 degree wide cone. Any angle >= 90 is an invalid cone angle, so a point light would return 90.0 and a spot light would return a value below 90, while a direct light would return 0.0 which defines perfectly parallel rays.

_validate()

void LightOp::_validate ( bool  for_real )

overridevirtual

Reimplemented from DD::Image::CameraOp.

knobs()

void LightOp::knobs ( Knob_Callback  f )

overridevirtual

Default knobs puts the transform controls on the front tab, and the projection, shutter, and lens controls on tab 'Projection'.

Reimplemented from DD::Image::CameraOp.

Reimplemented in DD::Image::LightSceneOp.

References DD::Image::Divider(), DD::Image::Newline(), and DD::Image::Tab_knob().

knob_changed()

int LightOp::knob_changed ( Knob *  k )

overridevirtual

Reimplemented from DD::Image::CameraOp.

build_handles()

void LightOp::build_handles ( ViewerContext *  ctx )

overridevirtual

Reimplemented from DD::Image::CameraOp.

draw_handle()

void LightOp::draw_handle ( ViewerContext *  ctx )

overridevirtual

Draws a picture of a point light.

Reimplemented from DD::Image::CameraOp.

Reimplemented in DD::Image::LightSceneOp.

shade_GL()

void LightOp::shade_GL ( ViewerContext *  ctx, int  light_num  )

virtual

Point light OpenGL settings.

Reimplemented in DD::Image::LightSceneOp, and DD::Image::ComplexLightOp.
