To modify the displayed Desktop, Windows needs to draw into these mirrored swap chains instead of its own. To accomplish this, all Direct3D functions that use a swap chain are hooked so that they return the mirrored swap chain, and any function that uses the contents of the swap chain are hooked. Basically any function that takes a Direct3D surface or texture is hooked and the respective item from the mirrored swap chains is returned if it is in the mirrored swap chain data structures."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of displaying an operating system's graphical user interface on a large multi-projector display","description":"The display of a Windows Desktop is modified using one or more processors (e.g. CPUs and/or GPUs) that re-direct drawing of the Desktop to mirrored swap chain buffers; modify the contents of the a fro","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514234","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
