Photorealistic Aquatic Plants Rendering with Cellular Structure

This paper presents a realistic real-time rendering method for aquatic plants, which considers their unique optical characteristics. While many render models has been proposed in real-time rendering of plant leaves, the rendering of aquatic plants is often inaccurate due to reliance on the botanical parameters and optical statistical characteristics of terrestrial plants. Through a qualitative analysis of the differences in optical properties between the cell structures of aquatic and terrestrial plants, we propose a rendering method for aquatic plants. The experimental results show that our method is effective in expressing the rendering appearance of aquatic plants. We also provide a solution for the construction of virtual reality underwater environments. Our contributions include a realistic real-time rendering model for aquatic plants, a real-time underwater roaming platform, and experimental evidence demonstrating our method's effectiveness in expressing the appearance of aquatic plants while balancing model efficiency and accuracy.
