outdoor canopy 3d model

Create a realistic 3D architectural model of a modern retractable outdoor canopy / pergola with a waterproof fabric roof. There is a large mature tree trunk located directly in the center of the covered area, so the design must intelligently adapt around the tree without cutting or damaging it. The canopy uses a lightweight metal or aluminum frame attached to the surrounding walls and/or independent posts. The retractable roof is divided into two or more fabric sections that slide or fold toward the sides, leaving a circular opening around the tree trunk when closed. Around the tree trunk, create a flexible circular sealing collar made of rubber or flexible waterproof material that can accommodate the natural movement and future growth of the tree.
