A system that implements a 'tangent space brush,' allowing a user to paint directly onto a parameterized object, for example a three dimensional object. A tangent space brush projects coordinates from an input device to the world-space point on the surface of the 3D object. A normal is determined at that point and a brush image is projected from that point, along the normal, to the underlying surfaces. The system is implemented by providing a system that implements selecting a selected area of a displayed object, and projecting a brush directly onto a surface of the selected area.

Dynamically adjusted brush for direct paint systems on parameterized multi-dimensional surfaces

A method for assigning background pixels an appropriate color to fill all remaining background pixels by a computer after standard paint and overscan techniques to prevent and reduce artifacts. The method includes computing an initial mipmap level and keeping track of which pixels are background pixels. Four pixels at a subsequent mipmap level correspond to a single pixel at a higher level. If the four pixels at the lower level are background pixels, then the single pixel is also a background pixel and a corresponding color is used. Otherwise, the color of the single pixel is the average of non-background pixels.
