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.

void vtkShaderProperty::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 vtkObject.

Reimplemented in vtkOpenGLShaderProperty.

◆ New()

static vtkShaderProperty * vtkShaderProperty::New ( )

static

Construct object with no shader replacements.

◆ DeepCopy()

void vtkShaderProperty::DeepCopy ( vtkShaderProperty * p )

Assign one property to another.

◆ GetShaderMTime()

vtkMTimeType vtkShaderProperty::GetShaderMTime ( )

GetShaderMTime returns the last time a modification was made that affected the code of the shader (either code replacement was changed or one or more uniform variables were added or removed.

This timestamp can be used by mappers to determine if the shader must be recompiled. Simply changing the value of an existing uniform variable doesn't affect this timestamp as it doesn't change the shader code.

Returns: timestamp of the last modification
