mitsuba::SpectrumAdditionTexture::SpectrumAdditionTexture | ( | Stream * | stream, |
InstanceManager * | manager | ||
) |
Reimplemented from mitsuba::HWResource.
|
inlinevirtual |
Return the texture value at its
.
filter | Specifies whether a filtered texture lookup is desired. Note that this does not mean that filtering will actually be used. |
Reimplemented from mitsuba::Texture.
|
inlinevirtual |
Return the component-wise average value of the texture over its domain.
Reimplemented from mitsuba::Texture.
Return a bitmap representation of the texture.
When the class implementing this interface is a bitmap-backed texture, this function directly returns the underlying bitmap. When it is procedural, a bitmap version must first be generated. In this case, the parameter sizeHint is used to control the target size. The default value -1, -1
allows the implementation to choose a suitable size by itself.
Reimplemented from mitsuba::Texture.

virtual |
Retrieve this object's class.
Reimplemented from mitsuba::Texture.
|
inlinevirtual |
Return the component-wise maximum of the texture over its domain.
Reimplemented from mitsuba::Texture.
|
inlinevirtual |
Return the component-wise minimum of the texture over its domain.
Reimplemented from mitsuba::Texture.

inlinevirtual |
Return whether the texture takes on a constant value everywhere.
Reimplemented from mitsuba::Texture.
|
inlinevirtual |
Return whether the texture is monochromatic / spectrally uniform.
The implementation may conservatively return false
if it is not sure.
Reimplemented from mitsuba::Texture.
|
virtual |
Serialize to a binary data stream.
Reimplemented from mitsuba::Texture.
|
inlinevirtual |
Return a human-readable string representation of the object's contents.
This function is mainly useful for debugging purposes and should ideally be implemented by all subclasses. The default implementation simply returns MyObject[unknown]
, where MyObject
is the name of the subclass.
Reimplemented from Object.

inlinevirtual |
Does this texture perform any pre-filtering when ray differentials are available?
