A Method of Generating Discontinuous Equivalent Cloud Image Based on Slice Rendering

Abstract

The invention provides a discontinuous equivalent cloud image generation method based on layer rendering, which includes: constructing a two-dimensional plane regular lattice; constructing a triangular network structure; embedding the two-dimensional fault structure boundary line into the triangular network structure, and integrating the triangular network The triangular surfaces that intersect with the fault structure boundary lines in the structure are deleted, and the interpolation results are reconstructed using the missing area boundaries as constraints to reconstruct the suture-type triangular network structure with boundary constraints; the suture-type triangulation network structure is reconstructed using the study area boundaries and fault structure boundary lines as constraints. The network uses a two-way link tracking method for contour tracking; an algorithm is designed based on the principle of "node orientation consistency" to track equivalent areas, and the tracked equivalent areas are grouped; the equivalent area tracking results are filtered to form a The isovalue area boundaries and fault structure boundary lines are re-zoned and meshed with strict constraints; the isovalue area triangular mesh patches are rendered according to the color bar division and color gradient, forming a discontinuous isovalue cloud map of the regional rendering results.

Description

technical field [0001] The invention relates to a method for generating discontinuous equivalent cloud images based on level rendering. Background technique [0002] Geological model simulation is a key step in the construction of the entire mine digital model, but the discontinuity of the geological structure increases the uncertainty of the geological information space, making it difficult for the geological visualization simulation model to fully express the geological structure information. Under normal conditions, the expression of discontinuous geological structure information is mainly through single-color entity partition modeling or single-color filling that ignores structural constraints. Although the above alternative methods solve the visualization of the simulation model to a certain extent, this model cannot Reflects the numeric properties contained within the range. For example, in the planning process of the buried depth contour area, on the premise of ensur...

Problems solved by technology

However, the traditional processing technology has high performance overhead, and the visualization effect is not obvious or the numerical attributes cannot be represented, resulting in simulation results that cannot meet the needs of engineering applications and digital simulation modeling requirements
