Module: Isosurface (Seismic) ()

Description:

The seismic Isosurface module is a specialized Isosurface Rendering module provided for convenience in seismic visualizations. This module can be attached to a seismic volume data object in order to generate isosurfaces that are computed and rendered on the graphics hardware.

This module does not compute geometry on the CPU. Thus, unlike for the standard Isosurface module, it is not possible to store the results as a surface object or as an Open Inventor format file.

This rendering technique needs more slices than typically used for volume rendering. A low number of slices will create holes in the surface.

This module provides a hardware-accelerated implementation, which uses programmable shader hardware to allow real-time rendering. On platforms that do not have programmable shader support, no isosurface will be drawn.

Connections:

Data [required]
The seismic volume data object from which the isosurface is generated.

ROI [optional]
Connection to a module providing a region-of-interest, like ROI Box Seismic. If such a module is connected, only the selected part of the volume will be displayed.

Colormap [optional]
Colormap used to visualize the data.

Ports:

Colormap

Port to select a colormap.

Number of slices

The larger this number, the better the image quality and the less the rendering performance. A low number of slices will create holes in the surface.

Threshold

Isovalue to be rendered.
