Detailed Description

GPU implementation of a Line Integral Convolution, a technique for imaging vector fields.

The input on port 0 is an 2D vtkStructuredGrid. It needs a vector field on point data. Port 1 is a special port for customized noise input. It is an optional port. If not present, noise is generated by the filter. Even if none-power-of-two texture are supported, giving a power-of-two image may result in faster execution on the GPU.

Please refer to Forssell, L. K., "Visualizing flow over curvilinear grid surfaces using line integral convolution", Visualization 94 Conference Proceedings, pages 240-247, IEEE Computer Society, 1994 for details of the algorithm.

Required OpenGL Extensions:: GL_ARB_texture_non_power_of_two GL_VERSION_2_0 GL_ARB_texture_float GL_ARB_draw_buffers GL_EXT_framebuffer_object GL_ARB_pixel_buffer_object

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 vtkStructuredGridAlgorithm.

int vtkStructuredGridLIC2D::SetContext ( vtkRenderWindow * context )

Get/Set the context.

Context must be a vtkOpenGLRenderWindow. This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions. Return 0 upon failure and 1 upon success.

Context must be a vtkOpenGLRenderWindow. This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions. Return 0 upon failure and 1 upon success.

virtual void vtkStructuredGridLIC2D::SetSteps ( int )

Number of steps.

Initial value is 1. class invariant: Steps>0. In term of visual quality, the greater the better.

virtual void vtkStructuredGridLIC2D::SetStepSize ( double )

virtual

Step size.

WE ARE NOT SURE YET about the space where we define the step. If the image data has different spacing in each dimension, it is an issue. Initial value is 1.0. class invariant: StepSize>0.0. In term of visual quality, the smaller the better. The type for the interface is double as VTK interface is double but GPU only supports float. This value will be converted to float in the execution of the algorithm.
