Detailed Description

precompute irradiance texture used in physically based rendering

Irradiance texture is a cubemap which average light of a hemisphere of the input cubemap. It is used in Image Base Lighting to compute the diffuse part.

static

◆ IsA()

virtual vtkTypeBool vtkPBRIrradianceTexture::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkOpenGLTexture.

◆ PrintSelf()

void vtkPBRIrradianceTexture::PrintSelf ( ostream &  os,
vtkIndent  indent

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkOpenGLTexture.

◆ SetInputCubeMap()

void vtkPBRIrradianceTexture::SetInputCubeMap ( vtkOpenGLTexture texture)

Get/Set the input cubemap.

◆ GetInputCubeMap()

◆ Load()

void vtkPBRIrradianceTexture::Load ( vtkRenderer )
overridevirtual

Implement base class method.

Reimplemented from vtkOpenGLTexture.

◆ Render()

void vtkPBRIrradianceTexture::Render ( vtkRenderer ren)
inlineoverridevirtual

Implement base class method.

Reimplemented from vtkOpenGLTexture.

Definition at line 57 of file vtkPBRIrradianceTexture.h.

◆ GetIrradianceSize()

virtual unsigned int vtkPBRIrradianceTexture::GetIrradianceSize ( )
virtual

Set/Get size of texture.

Default is 256.

◆ SetIrradianceSize()

virtual void vtkPBRIrradianceTexture::SetIrradianceSize ( unsigned int  )
virtual

◆ GetIrradianceStep()

virtual float vtkPBRIrradianceTexture::GetIrradianceStep ( )
virtual

Set/Get the size of steps in radians used to sample hemisphere.

Default is (pi/64). In some OpenGL drivers (OSMesa, old OSX), the default value might be too low leading to artifacts.

◆ SetIrradianceStep()

virtual void vtkPBRIrradianceTexture::SetIrradianceStep ( float  )
virtual

◆ GetConvertToLinear()

virtual bool vtkPBRIrradianceTexture::GetConvertToLinear ( )
virtual

Set/Get the conversion to linear color space.

If the input cubemap is in sRGB color space and the conversion is not done by OpenGL directly with the texture format, the conversion can be done in the shader with this flag.

◆ SetConvertToLinear()

virtual void vtkPBRIrradianceTexture::SetConvertToLinear ( bool  )

◆ ConvertToLinearOn()

virtual void vtkPBRIrradianceTexture::ConvertToLinearOn ( )

◆ ConvertToLinearOff()

virtual void vtkPBRIrradianceTexture::ConvertToLinearOff ( )
virtual

◆ ReleaseGraphicsResources()

void vtkPBRIrradianceTexture::ReleaseGraphicsResources ( vtkWindow )
overridevirtual

Release any graphics resources that are being consumed by this texture.

The parameter window could be used to determine which graphic resources to release. Using the same texture object in multiple render windows is NOT currently supported.

Reimplemented from vtkOpenGLTexture.
