摘要: Systems and methods for sketching reality are described. In one aspect, a set of vector primitives is identified from a 2-D sketch. In one implementation, the 2-D sketch is hand-drawn by a user. A 2.5D geometry model is automatically generated from the vector primitives. The 2.5D geometry model is automatically rendered and presented to a user. In one implementation, the user provides 2-D sketch-based user inputs to modify one or more of lighting position, lighting direction, lighting intensity, texture, color, and geometry of the presentation.
