Member Function Documentation

Shader* mitsuba::ConstantFloatTexture::createShader ( Renderer * renderer ) const

virtual

Reimplemented from mitsuba::HWResource.

Spectrum mitsuba::ConstantFloatTexture::eval	(	const Intersection &	its,
		bool	filter
	)		const

inlinevirtual

Return the texture value at its.

Parameters

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.

Spectrum mitsuba::ConstantFloatTexture::getAverage ( ) const

inlinevirtual

Return the component-wise average value of the texture over its domain.

Reimplemented from mitsuba::Texture.

ref<Bitmap> mitsuba::ConstantFloatTexture::getBitmap ( const Vector2i & sizeHint ) const

virtual

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 const Class* mitsuba::ConstantFloatTexture::getClass ( ) const

virtual

Retrieve this object's class.

Reimplemented from mitsuba::Texture.

Spectrum mitsuba::ConstantFloatTexture::getMaximum ( ) const

inlinevirtual

Return the component-wise maximum of the texture over its domain.

Reimplemented from mitsuba::Texture.

Spectrum mitsuba::ConstantFloatTexture::getMinimum ( ) const

inlinevirtual

Return the component-wise minimum of the texture over its domain.

Reimplemented from mitsuba::Texture.

bool mitsuba::ConstantFloatTexture::isConstant ( ) const

inlinevirtual

Return whether the texture takes on a constant value everywhere.

Reimplemented from mitsuba::Texture.

bool mitsuba::ConstantFloatTexture::isMonochromatic ( ) const

inlinevirtual

Return whether the texture is monochromatic / spectrally uniform.

The implementation may conservatively return false if it is not sure.

Reimplemented from mitsuba::Texture.

void mitsuba::ConstantFloatTexture::serialize	(	Stream *	stream,
		InstanceManager *	manager
	)		const

virtual

Serialize to a binary data stream.

Reimplemented from mitsuba::Texture.

std::string mitsuba::ConstantFloatTexture::toString ( ) const

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.

bool mitsuba::ConstantFloatTexture::usesRayDifferentials ( ) const

inlinevirtual

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

Reimplemented from mitsuba::Texture.
