Animatable graphics lighting analysis reporting

摘要

One embodiment of the invention sets forth a mechanism for displaying lighting values associated with a 3-D graphics model by superimposing an overlay grid with lighting values on the 3-D graphics model. A software rendering engine computes lighting values for each frame that includes the 3-D graphics model, where each frame may have different lighting settings. An overlay grid with lighting values may be superimposed on an area defined by a light meter on the 3-D graphics model. The lighting values on the overlay grid are associated with the light meter and may vary frame-over-frame. In another embodiment, a JPEG image with a superimposed overlay grid with per-pixel lighting values covering a 3-D graphics model is generated for each frame that includes the 3-D graphics model. These JPEG images may be displayed on the screen and stored to an external memory.

主权项

1. A method for displaying lighting values associated with a graphics model, the method comprising:
generating a light meter on a surface associated with the graphics model, wherein the graphics model includes one or more graphics objects, and the light meter defines a set of points on the surface associated with the graphics model; generating a light meter object corresponding to the light meter; computing a lighting value for each point in the set of points based on at least one light source associated with the graphics model to generate a first set of computed lighting values; storing the first set of computed lighting values in the light meter object; rendering, via a processing unit, the graphics model, a first overlay grid, and the first set of computed lighting values transmitted from the light meter object for display in a first display window, wherein the first overlay grid and the first set of computed lighting values are superimposed on the graphics model, and each grid point in the first overlay grid corresponds to a computed lighting value stored in the light meter object; and changing at least one of the displayed lighting values based on a timeline associated with the first display window; wherein an area in the display image covered by the first overlay grid is shaded based on the first set of computed lighting values.
