Tools for 3D mesh and texture manipulation

A method for restoring a previous version of a three dimensional mesh model on a computer system comprising:

• retrieving a stored copy of an earlier state of the three dimensional mesh model on the computer system;
• retrieving an ordered list of operations on the computer system;
• and
• performing at least some of the operations in the ordered list of operations on the retrieved copy of the three dimensional mesh model;
• wherein the ordered list of operations contains the operations which if performed in order on the earlier state of the three dimensional mesh model would result in a current state of the three dimensional mesh model.

An article of manufacture comprising a computer-readable medium having stored thereon instructions adapted to be executed by a processor, the instructions which, when executed, define a series of steps to be used for managing a three dimensional mesh model, said steps comprising:

• storing a copy of a first state of the three dimensional mesh model;
• performing operations on the three dimensional mesh model, wherein the three dimensional mesh model is in a second state after performing the operations;
• storing a record of each of the operations in an ordered list;
• and
• reapplying at least some of the operations stored in the ordered list to the stored first state of the three dimensional mesh model, wherein the three dimensional mesh model is in a third state after reapplying the at least some of the operations.

A system for managing a three dimensional mesh model, the system comprising:

• a computer module that stores a copy of a first state of the three dimensional mesh model;
• a computer module that performs operations on the three dimensional mesh model, wherein the three dimensional mesh model is in a second state after performing the operations;
• a computer module that stores a record of each of the operations in an ordered list;
• and
• a computer module that reapplies at least some of the operations stored in the ordered list to the stored first state of the three dimensional mesh model, wherein the three dimensional mesh model is in a third state after reapplying the at least some of the operations.
