3D Soft Surface Decorative Article Simulator

A method for simulating carpet in three dimensions comprising the steps of:

• receiving parameters for modeling of a yarn;
• modeling a tuft of the yarn using the received parameters;
• based on the modelled tuft of the yarn, creating a descriptor file for a carpet;
• submitting the descriptor file to a rendering engine,
• wherein the descriptor file comprises a selection of a model from the rendering engine, and
• wherein the model from the rendering engine comprises a parent and children model for filament modeling;
• simulating a plurality of yarns based on a yarn texture, a yarn color, a pile height, a pile type, or a user preference from the received parameters;
• and
• displaying the simulated carpet.

A method for simulating carpet in three dimensions comprising the steps of:

• receiving parameters for modeling of a yarn, wherein the yarn is multi-ply yarn;
• modeling a tuft of the yarn using the received parameters;
• based on the modelled tuft of the yarn, creating a descriptor file for a carpet;
• submitting the descriptor file to a rendering engine;
• and
• displaying the simulated carpet,
• wherein the simulated carpet comprises a turf with simulated blades of grass and simulated pieces of thatch,
• wherein the simulated blades of grass have constraints on angles of bends, and wherein the simulated pieces of thatch have no constraints on the angles of the bends.

A method for simulating carpet in three dimensions comprising the steps of:

• receiving parameters for modeling of a yarn;
• modeling a tuft of the yarn using the received parameters;
• based on the modelled tuft of the yarn, creating a descriptor file for a carpet;
• submitting the descriptor file to a rendering engine, wherein the rendering engine is Blender and the descriptor file comprises selection of a model and model parameters from Blender;
• and
• displaying the simulated carpet, wherein the simulated carpet comprises:
• a turf having simulated pieces of thatch;
• and
• simulated blades of grass,
• wherein the simulated pieces of thatch may bend along an axis parallel to a length of the thatch and the simulated pieces of thatch may bend along an axis perpendicular to the length of the thatch, and wherein the simulated blades of grass may only bend along an axis perpendicular to a length of the blade of grass.
