Calculation of polygon-based holograms for textured surfaces using orthogonal projection

In the current landscape of technological advancements, holography is acknowledged as one of the most promising three-dimensional display technologies. To enhance the quality of holographic reproductions and address the issue of texture mapping distortion, this paper proposes an innovative method based on orthogonal texture mapping for generating three-dimensional model-computed holograms. This approach leverages the analytical polygonal element method, incorporates the Blinn-Phong reflection model to acquire lighting information, and employs orthogonal projection for obtaining texture information. The result is the generation of high-quality three-dimensional object-computed holograms. Numerical simulation experiments demonstrate that the holographic reconstructions generated by our method exhibit undistorted and non-distorted textures on the surface, presenting superior visual quality. This method holds significant theoretical and practical value.
