8.7 The shadowmap display driver

Use this display driver to create shadow maps without passing by a zfile. Shadow maps in 3Delight are normal TIFFs. The following parameter can be passed to this display driver.

"uniform string zcompression" "lzw|zip|none"

Enables or disables compression. Disabled by default.

"integer aggregate" [0]

By default, the shadowmap display driver will overwrite the shadow map if it already exists. Setting this parameter to `1' will cause the display driver to concatenate the currently generated shadow map to the existing one. This very useful feature can create shadow maps for point lights: rendering all six views to a single shadow map file is much more usable than dealting with six different shadow maps. More about his feature in Aggregated Shadow Maps.

There is no need to run tdlmake on files produced by this display driver, since they are already in the right format.
