Detailed Description

assign texture coordinates for a projected texture.

Date:
2000/12/10 20:08:25
Revision:
1.11

vtkProjectedTexture assigns texture coordinates to a dataset as if the texture was projected from a slide projected located somewhere in the scene. Methods are provided to position the projector and aim it at a location, to set the width of the projector's frustum, and to set the range of texture coordinates assigned to the dataset.

Objects in the scene that appear behind the projector are also assigned texture coordinates; the projected image is left-right and top-bottom flipped, much as a lens' focus flips the rays of light that pass through it. A warning is issued if a point in the dataset falls at the focus of the projector.

Member Function Documentation

vtkProjectedTexture* vtkProjectedTexture::New (    )  [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkDataSetSource.

virtual const char* vtkProjectedTexture::GetClassName (    )  [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataSetToDataSetFilter.

int vtkProjectedTexture::IsTypeOf (  const char *    type )  [static]
 

Return 1 if this class type 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 vtkDataSetToDataSetFilter.

virtual int vtkProjectedTexture::IsA (  const char *    type )  [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 vtkDataSetToDataSetFilter.

vtkProjectedTexture* vtkProjectedTexture::SafeDownCast (  vtkObject *    o )  [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataSetToDataSetFilter.

void vtkProjectedTexture::PrintSelf (  ostream &    os,
vtkIndent    indent
)  [virtual]
 

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 vtkSource.

virtual void vtkProjectedTexture::SetPosition (  float   ,
float   ,
float   
)  [virtual]
 

Set/Get the position of the focus of the projector.

virtual void vtkProjectedTexture::SetPosition (  float   [3] )  [virtual]

virtual void vtkProjectedTexture::GetPosition (  float    data[3] )  [virtual]
 

void vtkProjectedTexture::SetFocalPoint (  float    focalPoint[3] ) 
 

Set/Get the focal point of the projector (a point that lies along the center axis of the projector's frustum).

float    y,
float    z
) 
 

virtual float* vtkProjectedTexture::GetFocalPoint (    )  [virtual]

virtual void vtkProjectedTexture::GetAspectRatio (  float    data[3] )  [virtual]
 

virtual void vtkProjectedTexture::SetSRange (  float   ,
float   
)  [virtual]
 

Specify s-coordinate range for texture s-t coordinate pair.

void vtkProjectedTexture::SetSRange (  float   [2] ) 
 

virtual float* vtkProjectedTexture::GetSRange (    )  [virtual]
 

virtual void vtkProjectedTexture::GetSRange (  float    data[2] )  [virtual]
