Provided are a
processing system for a three-dimensional model, a method for obtaining a
physical model on the basis of three-dimensional printing of a three-dimensional
processing system, a
system for generating a three-dimensional model from a
virtual reality /
augmented reality three-dimensional sketch, a
diffusion model training method, and a method for editing a three-dimensional model on the basis of a
virtual reality /
augmented reality three-dimensional sketch. The method for obtaining a
physical model on the basis of three-dimensional printing of a three-dimensional
processing system comprises: step one, at an input apparatus, a user using a hand or a
handle to draw three-dimensional sketch content in the air, wherein a three-dimensional sketch is stored in the form of a three-dimensional
point cloud, and when the user draws a trajectory, a corresponding
point cloud is generated in the drawn trajectory and is displayed in a three-dimensional
virtual space in a highlighted manner, and displacement and deletion operations of the user for the three-dimensional sketch are overall displacement and deletion operations for points in a region corresponding to the
point cloud of the three-dimensional sketch; step two, a computing apparatus converting the three-dimensional sketch content into a three-dimensional model; step three, converting the three-dimensional model into a readable file for an execution apparatus, wherein the conversion is implemented by using a
slicing algorithm; and step four, a three-dimensional printer executing the readable file to perform a printing operation, so as to obtain a
physical model.
