IDSS: a novel representation for woven fabrics.

Area of Science:

• Computer Graphics
• Geometric Modeling
• Textile Science

Background:

• The visual appearance of woven fabrics depends heavily on their intricate meso/micro-scale geometric structure.
• Accurate digital representation of these structures is crucial for realistic rendering in computer graphics.

Purpose of the Study:

• To propose a novel multiscale representation and tessellation approach for digitally rendering woven fabrics.
• To enhance the realism and efficiency of woven fabric appearance modeling in real-time graphics.

Main Methods:

• Extension of the Displaced Subdivision Surface (DSS) to Interlaced/Intertwisted Displacement Subdivision Surface (IDSS).
• Utilizing Bezier patches to approximate the ternary interpolatory subdivision surface for geometric detail mapping.
• Implementation using DirectX 11 (DX11) graphics pipeline primitives, including the Woven Patch structure with hull, tessellator, and domain shaders.

Main Results:

• Successful rendering of woven fabrics with high geometric fidelity, capturing yarn and fiber variances.
• Achieved real-time performance (25 frames per second) on a low-end mobile GPU (NVIDIA 8400 MG).
• Demonstrated the scalability of the IDSS approach for large-scale fabric representations.

Conclusions:

• The proposed IDSS method provides an effective and efficient approach for realistic woven fabric rendering.
• The Woven Patch primitive and DX11 implementation facilitate integration into modern graphics pipelines.
• This technique enables high-quality digital textile representation for various applications.
