LightOp defines a 3D light.
Light base class which defaults to point source lighting with falloff.
|
virtual |
Whether the light has a delta distribution (point/spot/direct lights)
Reimplemented in DD::Image::ComplexLightOp.
|
virtual |
Calculate direction vector and distance from this light to P.
Calculate a normalized direction vector L and distance D to surface point P. Surface normal N is passed to allow lights like area lights to simulate a large emission surface.
Reimplemented in DD::Image::ComplexLightOp.
References DD::Image::Vector3::fast_normalize(), and DD::Image::Vector3::normalize().
Referenced by DD::Image::ComplexLightOp::get_L_vector().
|
virtual |
Return the amount of shadowing the light creates at surface point P. and optionally copies the shadow mask to the output pixel.
Project surface point P into light's view aperture and test if it's further in Z than the shadow buffer sample. Jittered multi- sampling of the shadow buffer is supported when samples is greater than 1 which produces soft edged shadows.

|
virtual |
Return the color of this light. The light vector and distance are passed.
Returns the color of the light (possibly) using the current surface point and normal to calculate attenuation and penumbra. The base class returns a point source attenuated by the inverse squared distance.
Reimplemented in DD::Image::ComplexLightOp.
References color_, falloffType_, and intensity_.
|
inlinevirtual |
field-of-view methods.
Reimplemented in DD::Image::ComplexLightOp.
Referenced by DD::Image::ComplexLightOp::hfov().
|
virtual |
Handle channel requests. Base class does nothing, but Lights that read imagery such as environment maps will need to implement this.
