Fused-s Lush Leaves V1.5 Apr 2026
Author: Computational Botany & Graphics Group Version: 1.5 Date: April 2026 Abstract We present Fused-S Lush Leaves v1.5 , a novel hybrid framework for synthesizing dense, botanically plausible foliage in real-time and offline rendering pipelines. Building upon the limitations of v1.0–v1.4, this version introduces a spectral fusion layer (S-Fusion) that combines geometric detail from multi-view photogrammetry with stochastic spectral sampling of leaf optical properties. The result is a significant reduction in overdraw artifacts (≈34%) while improving leaf translucency and canopy self-shadowing coherence. v1.5 achieves a 2.1× performance gain over v1.4 in scenes exceeding 500k leaves. 1. Introduction Procedural foliage generation remains challenging due to the tension between geometric density, memory footprint, and realistic light interaction. Prior versions (Fused-S v1.0–v1.4) relied on a single-stream fusion of LIDAR point clouds and precomputed leaf atlases, leading to temporal aliasing under dynamic lighting.
