Energy viewset (energy-03)
The energy-03 viewset is based on rendering techniques used by the open-source OpendTect seismic visualization application.
Similar to medical imaging such as MRI or CT, geophysical surveys generate image slices through the subsurface that are built into a 3D grid. Volume rendering provides a 2D projection of this 3D volumetric grid for further analysis and interpretation. In addition to the volume rendering, the test includes both inline and crossline planes (slices in the X and Y planes). Some subtests contain horizons, which are geological strata boundaries of interest, generated by exploration geophysicists, and are rendered using textured triangle strips.
The 3D datasets used in this viewset are real-world seismic datasets found at https://wiki.seg.org/wiki/Open_data. They were translated from their native SEG-Y format and compressed using JPEG-2000.
Note: subtests 3 and 6 will have a score of 0.01 on GPUs with less than 1GB of framebuffer memory.
