Detailed Description

handles properties associated with a texture map

vtkTexture is an object that handles loading and binding of texture maps. It obtains its data from an input image data dataset type. Thus you can create visualization pipelines to read, process, and construct textures. Note that textures will only work if texture coordinates are also defined, and if the rendering system supports texture.

Instances of vtkTexture are associated with actors via the actor's SetTexture() method. Actors can share texture maps (this is encouraged to save memory resources.)

Warning: Currently only 2D texture maps are supported, even though the data pipeline supports 1,2, and 3D texture coordinates.; Some renderers such as old OpenGL require that the texture map dimensions are a power of two in each direction. If a non-power of two texture map is used, it is automatically resampled to a power of two in one or more directions, at the cost of an expensive computation. If the OpenGL implementation is recent enough (OpenGL>=2.0 or extension GL_ARB_texture_non_power_of_two exists) there is no such restriction and no extra computational cost.

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 vtkImageAlgorithm.

Reimplemented in vtkOpenGLTexture, and vtkOpenGLTexture.

void vtkTexture::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 vtkImageAlgorithm.

Reimplemented in vtkOpenGLTexture, and vtkOpenGLTexture.

virtual void vtkTexture::Render ( vtkRenderer * ren )

virtual

Renders a texture map.

It first checks the object's modified time to make sure the texture maps Input is valid, then it invokes the Load() method.

Reimplemented in vtkOpenGLTexture.

virtual void vtkTexture::PostRender ( vtkRenderer * )

inlinevirtual

Cleans up after the texture rendering to restore the state of the graphics context.

Reimplemented in vtkOpenGLTexture, and vtkOpenGLTexture.

Definition at line 88 of file vtkTexture.h.

virtual void vtkTexture::ReleaseGraphicsResources ( vtkWindow * )

inlinevirtual

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

The parameter window could be used to determine which graphic resources to release.

Reimplemented in vtkOpenGLTexture, and vtkOpenGLTexture.

Definition at line 95 of file vtkTexture.h.

virtual void vtkTexture::Load ( vtkRenderer * )

inlinevirtual

Abstract interface to renderer.

Each concrete subclass of vtkTexture will load its data into graphics system in response to this method invocation.
