Project Description:
We are a company designing custom inflatable themed decor.
We need a Rhino 7+ Grasshopper + Kangaroo specialist to create a reusable simulation system to test the inflation of complex 3D shapes — including internal ribs, belts, or tendons — before we send designs to production.
This system will help us predict the final inflated shape accurately and design reinforcements where needed.
Here is a video for similar project.
We need a system for closed mesh model with ribs.
A 3D model to be used for test is attached.
Deliverables:
A fully working Grasshopper (.gh) file that includes:
Mesh import functionality for custom inflatable shapes
Internal rib and belt/tendon support using Kangaroo Length or spring components
Pressure simulation using Pressure + Solver
Control over:
Inflation pressure
Rib/tendon stiffness and anchor points
Mesh anchor/fixed points
Organized with groups, sliders, toggles, and labels for usability
Preview output: final deformed shape for production comparison
A step-by-step video tutorial showing:
How to import a mesh into the system (supported file types below)
How to define and connect internal ribs and tendons to the inflatable mesh
How to position reinforcements (belts, ribs) in specific areas (e.g., fingers, joints, folds)
Tips for achieving accurate simulated shapes that closely match real-world inflation
Basic setup for preparing the mesh in Blender or Rhino
File Requirements:
Mesh Types:
Must support closed, triangulated mesh models (.OBJ or Rhino .3dm)
Mesh should be watertight and manifold
Ideal models are exported from Blender or modeled directly in Rhino
Ribs / Tendons:
Can be modeled as:
Lines (curves) inside the mesh
Thin meshes or pipes following specific paths (e.g., wrist to fingers)
Ribs must be positioned inside the inflatable and either:
Anchored to internal points
Connected directly to mesh vertices or face groups
Reinforcements should:
Be usable for shaping complex forms (e.g., hands, creatures, domes)
Visibly influence the final inflated mesh in the simulation
Be adjustable by the user in the provided system
Reusability:
This setup should be made as a template definition that we can reuse by:
Replacing the mesh
Replacing or editing internal ribs/tendons
Adjusting inflation strength and control points
Skills Required:
Advanced experience with Rhino + Grasshopper
Proficiency in Kangaroo2 physics simulation
Understanding of membrane structures, inflatable deformation, or soft body design
Clear communication skills to explain the setup in video tutorial format
Timeline & Budget:
Delivery deadline: within 5–7 days
Budget: Open — based on quality, experience, and proposal details
