In one embodiment, a stack of individual images of a scene are created. Each individual image corresponds to a respective light source or light source group associated with the scene. The individual images are combined to produce a combined image. The combined image is displayed. In response to user input indicating adjustments to a light source or light source group, an operator is applied to a corresponding individual image of the stack of individual images. An updated combined image is displayed on the display screen. Values for light sources or light source groups are generated based on the applied operator. The generated values are provided to a design session in a modeling environment.

A system and method providing an optimal way to create, manage and use resource data is provided. In an exemplary embodiment, the system and method provide the ability to store resource data in a library, namely a resource library. A resource library includes resource files that can be attached to a regular data file either automatically, for example, by setting an environment variable, or manually. More than one resource library or resource file may be created and simultaneously attached to a data file. The resource file defines attributes of elements that may be used in creating the CAD model. Typically, the resource library includes attributes that are to be standardized across a project, file, or model.

A method of rendering a glyph of a vector-based font comprises the steps of: generating a MIP map for a glyph, where the MIP map comprises at least one level having a plurality of pixels and where each level is generated from original vector data for the glyph; and storing the MIP map on a computer readable medium. The method further comprises placing the glyph in an image to be rendered; retrieving the stored MIP map for the glyph; rendering a level of the MIP map, where the level is associated with a resolution of the glyph; and displaying the glyph as the rendered level.
