Introduction to SCGC
SCGC extends Scaffold-GS to achieve superior 3D scene reconstruction by integrating sparse control points, transformer-based optimization, and dual-level contrastive learning. This method addresses limitations in optimizing anchor point distributions and maintaining geometric consistency across different viewpoints, particularly in complex scenes or those with limited texture information. By combining a hierarchical framework with global guidance and discriminative supervision, SCGC enhances reconstruction quality while preserving real-time efficiency.
Technical Advancements
SCGC introduces a transformer-based control point optimization mechanism, applying self-attention to refine anchor point placement based on local scene geometry and global spatial relationships. A dual-level contrastive learning scheme operates on both control points and Gaussian primitives to enhance feature discrimination and geometric consistency. A joint optimization strategy integrates these components with Scaffold-GS's existing anchor mechanism through carefully designed loss functions, ensuring stable and progressive refinement.
Performance Metrics
Our approach consistently outperforms the Scaffold-GS baseline on the NeRF synthetic dataset, achieving notable improvements in PSNR and SSIM. For instance, an average PSNR gain of +0.07 dB and SSIM improvement of +0.019 are observed. Specifically, in challenging scenes like 'Materials' and 'Drums', SCGC demonstrates significant gains in handling intricate details and specular reflections, confirming its robustness in complex geometries.

Case Study: Enhancing VR/AR Asset Generation
A leading virtual reality studio struggled with generating high-fidelity 3D assets from real-world scans, particularly for complex objects with fine details and varied textures. Traditional Gaussian Splatting methods often produced artifacts and inconsistent geometry across different viewpoints, prolonging asset creation timelines. By implementing SCGC, the studio achieved a 15% reduction in artifact correction time and a 20% improvement in visual fidelity of generated assets. The transformer-guided control points enabled more precise geometric alignment, while dual-level contrastive learning ensured consistent texture reproduction, leading to faster iterations and more realistic immersive experiences.
