Abstract
Underground flow paths (UFP) often play an important role in the illustration of geological data by geologists, especially in illustrating geological data and revealing stratigraphic structures, which can help domain experts in their exploration of petroleum information. In this paper, we present a new immersive visualization tool to help domain experts better illustrate stratigraphic data. We use a visualization method based on bit-array-based 3-D texture to represent stratigraphic data. Our visualization tool has three major advantages: it allows for flexible interaction at the immersive device, it enables domain experts to obtain their desired UFP structure through the execution of quadratic surface queries, and supports different stratigraphic display modes, as well as switching and integration geological information flexibly. Feedback from domain experts has shown that our tool can contribute more for domain experts in the scientific exploration of stratigraphic data, compared to the existing UFP visualization tools in the field. Thus, experts in geology can have a more comprehensive understanding and more effective illustration of the structure and distribution of UFPs.
Highlights
Geological refraction data, referred to as geological data, can help illustrate geological formations using data obtained from the propagation of geological waves in different parts of the subsurface
Augmented Reality (AR) and Virtual Reality (VR), which are usually used as a data-driven presentation medium for exploration and experience, can achieve better spatial perception and increase authenticity, and can present a data-driven process of exploration and experience
The rendering component of stratigraphic data in immersive visualization was developed based on GPU rendering and CG libraries
Summary
Geological refraction data, referred to as geological data, can help illustrate geological formations using data obtained from the propagation of geological waves in different parts of the subsurface. Compared to traditional volume data, such as CT scan volume data and medical volume data, geological data has a noise problem in the results acquired due to current limitations in survey technology. This affects the clear interpretation of stratigraphic data by experts in the field. The quadratic surface-based query can help experts explore the structure of UFPs and local regions. AR and VR can achieve better spatial perception and increase authenticity, and are usually used as a data-driven presentation medium for exploration and experience. Narrative visualization in immersive environments [8] can help users better understand domain knowledge and provide users with an intuitive experience of interactively exploring scientific data. Scientific visualization mainly focuses on the visualization of three-dimensional (3-D) phenomena, which is an interdisciplinary application field in science
