Detailed Description

public API for surface lic parameters arbitrary geometry.

vtkSurfaceLICInterface performs LIC on the surface of arbitrary geometry. Point vectors are used as the vector field for generating the LIC. The implementation was originallu based on "Image Space Based Visualization on Unsteady Flow on Surfaces" by Laramee, Jobard and Hauser appeared in proceedings of IEEE Visualization '03, pages 131-138.

vectors                                         surface LIC

PROj - prject vectors onto surface GAT - gather data for compositing and guard pixel generation (parallel only) COMP - composite gathered data LIC2D - line intengral convolution, see vtkLineIntegralConvolution2D. SCAT - scatter result (parallel only, not all compositors use it) SHADE - combine LIC and scalar colors CCE - color contrast enhancement (optional) DEP - depth test and copy to back buffer

The result of each stage is cached in a texture so that during interaction a stage may be skipped if the user has not modified its parameters or input data.

The parallel parts of algorithm are implemented in vtkPSurfaceLICInterface. Note that for MPI enabled builds this class will be automatically created by the object factory.

Definition at line 76 of file vtkSurfaceLICInterface.h.

Member Enumeration Documentation

◆ anonymous enum

anonymous enum

Enable/Disable contrast and dynamic range correction stages.

Contrast enhancement can be enabled during LIC computations (See vtkLineINtegralComvolution2D) and after the scalar colors have been combined with the LIC.

The best approach for using this feature is to enable LIC enhancement, and only if the image is to dark or dull enable COLOR enhancement.

Both stages are implemented by a histogram stretching algorithm. During LIC stages the contrast enhancement is applied to gray scale LIC image. During the scalar coloring stage the contrast enhancement is applied to the lightness channel of the color image in HSL color space. The histogram stretching is implemented as follows:

L = (L-m)/(M-m)

where, L is the fragment intensity/lightness, m is the intensity/lightness to map to 0, M is the intensity/lightness to map to 1. The default values of m and M are the min and max taken over all fragments.

This increase the dynamic range and contrast in the LIC'd image, both of which are natuarly attenuated by the convolution process.

Values

ENHANCE_CONTRAST_OFF – don't enhance LIC or scalar colors ENHANCE_CONTRAST_LIC – enhance in LIC high-pass input and output ENHANCE_CONTRAST_COLOR – enhance after scalars are combined with LIC ENHANCE_CONTRAST_BOTH – enhance in LIC stages and after scalar colors

This feature is disabled by default.

◆ anonymous enum

anonymous enum

Set/Get the color mode.

The color mode controls how scalar colors are combined with the LIC in the final image. The BLEND mode combines scalar colors with LIC intensities with proportional blending controlled by the LICIntensity parameter. The MAP mode combines scalar colors with LIC, by multiplication the HSL represntation of color's lightness.

The default is COLOR_MODE_BLEND.

void vtkSurfaceLICInterface::SetEnhanceContrast ( int val )

Enable/Disable contrast and dynamic range correction stages.

Contrast enhancement can be enabled during LIC computations (See vtkLineINtegralComvolution2D) and after the scalar colors have been combined with the LIC.

The best approach for using this feature is to enable LIC enhancement, and only if the image is to dark or dull enable COLOR enhancement.

Both stages are implemented by a histogram stretching algorithm. During LIC stages the contrast enhancement is applied to gray scale LIC image. During the scalar coloring stage the contrast enhancement is applied to the lightness channel of the color image in HSL color space. The histogram stretching is implemented as follows:

L = (L-m)/(M-m)

where, L is the fragment intensity/lightness, m is the intensity/lightness to map to 0, M is the intensity/lightness to map to 1. The default values of m and M are the min and max taken over all fragments.

This increase the dynamic range and contrast in the LIC'd image, both of which are natuarly attenuated by the convolution process.

Values
