Abstract:

Background: To simulate the anisotropic solid texture in 3D space, a kind of solid texture synthesis algorithm based on the samples that extends the 2D texture patch pasting technology to 3D hepatic artery solids is proposed.

Methods: Firstly, the surface model is tetrahedral with Delaunay tetrahedral method. Secondly, the color attribute is used to generate the depth field and the depth field gradient direction is the first vector field, then the second vector field is defined by the arrow icon. The third vector is the product of the first two vectors. Finally, the vector field of the whole model is generated by Laplasse interpolation.

Results & Conclusion: The experimental results showed that the proposed method can be used to synthesize the desired texture effect on any three-dimensional region, and it can simulate the internal structure of the hepatic artery and realize the real-time visualization of the cutting.

Keywords: Virtual surgery, hepatic artery, anisotropic, volumetric tensor fields, solid texture example, 3D space.
