  • Workflow system for 3D model creation
    Patent number: 9111371
    Abstract: A 3D modeling workflow system is disclosed that allows the user to create multiple 2D planes or paint canvases in the 3D scene each having a position and orientation. These 2D planes can be arbitrarily positioned in the 3D scene and can contain a combination of paint and model construction geometry. The construction geometry can span multiple 2D planes. The user is allowed to sketch on the planes using paint and create curve geometry in and between the planes using the sketches as a reference. Collectively the 2D planes allow a 3D object to be represented with different types of input where portions of the object are drawn in by paint and other or the same portions are composed of geometry. The user can swap between painting on the 2D planes and creating model geometry as needed.
