Interactive image editing

摘要

A 2-D image editor 23 is provided which can apply paint, texture, special effects such as fog and entourage, to a rendered 2-D image in proper perspective relative to the 3-D scene represented by the 2-D image. The image editor 23 determines the perspective on a pixel by pixel basis using a z-buffer which contains a depth value for each pixel in the 2-D image to be edited. The 2-D image may be created by a renderer 21 rendering a 3-D geometrical model output by a 3-D modelling unit 19.
