Drilling core visualization from X-ray Micro-CT using CUDA
GPU Visualization of drilling cores obtained by X-ray microtomography using CUDA.
Category: Oil Industry Applications
Technologies: Drilling core visualization, CUDA, GPU, VTK.
The next figure shows a volume rendering obtained with an NVidia GPU GT525M of 96 cores, hosted on my Dell laptop. In the top of the figure a performance of 53.4 frames per second is reported. We are using Ray Casting.
As database we are using the cube brique_02v2c300of of dimensions 300x300x300, obtained by micro-CT, with 2 micron resolution, this cube can be downloaded at the following link:

The next figure shows again the same cube, using a visualization pipeline based on VTK.
The differences between the two views lies in:
-
The color palette used in the first figure was constructed from 9 colors, sub sampled from the color palette used in the second figure with 256 colors.
-
The perspective in the first figure is stronger than in the second figure.
-
Lighting conditions.
All the conditions can be matched and get exactly the same result.
