Volume rendering of Argon Bubble data set (time step 250) showing the outlines of separate AMR grids (level 0 (coarsest) grids are outlined in red, level 1 grids in yellow, level 2 (finest) grids in green). Rendering of 800x600 image took less than 0.1s. |
 |
Volume rendering of time step 500 of Argon Bubble data set. Note that the AMR hierarchy automatically adapts to the increase in complexity in the data set - there are more level 1 and level 2 grids, and they follow the bubble as it moves through the domain. |
 |
Volume rendering of time step 750 of Argon Bubble data set. |
 |
Volume rendering of time step 500 of Argon Bubble data set without embedded grid structure. The different shades of green visible in the data set's background are rendering artifacts due to the limited color buffer resolution of the used NVidia GeForce 4 graphics card. |
 |
Same volume rendering as above, performed on an SGI Onyx2 with two Infinite Reality3 graphics pipes. The IR3's higher color buffer resolution (12 bit vs. 8 bit) removes the visual artefacts exhibited in the image above. |

Volume rendering of an X-ray computed tomography of a computer mouse. The original rectilinear data set (800 x 800 x 1035 voxels) was converted to a five-level AMR hierarchy by our AMRizer tool. The original data set's size was reduced by a factor of 34, from 631 MB to 18 MB, in the process. This image used only the coarsest two levels, levels 0 and 1, for rendering. |

Volume rendering of computer mouse, using levels 0, 1 and 2 for rendering. |
 |
Volume rendering of computer mouse, using all five levels for rendering. |
 |
Close-up of internal circuitry of computer mouse, showing the intricate detail captured in the original X-ray computed tomography and its faithful reproduction by the AMR renderer. |
