renderdl reads a file containing scene description commands and “executes” them. Such files are commonly called NSI files (NSI stands for Nodal Scene Interface). There are two kinds of NSI files: ASCII encoded and binary encoded. A binary NSI file is smaller than its ASCII encoded equivalent, but an ASCII NSI file has the advantage of being human readable and editable in any a text editor or word processor.
To render a file named file.nsi, just type:
...
If no file name is specified, renderdl reads scene description commands from the standard in. This feature enables piping commands directly in renderdl. For example, to enter scene description commands interactively (which is not really practical), do the following:
| Code Block |
|---|
renderdl Reading (stdin) <enter commands here> |
If you wish to pipe the content of file.nsi in renderdl, type:
| Code Block |
|---|
cat file.nsi | renderdl |
Command Line Options
| Option | Description | ||||||
|---|---|---|---|---|---|---|---|
-t n | Specifies the number of threads to use for the rendering. "n" can take any of the following values:
| ||||||
-stats | Embed statistics in rendered images. This is supported for EXR and TIFF files only. Statistics are explained in more detail in Understanding 3Delight Statistics. | ||||||
-progress | Prints a progress status after each rendered bucket. | ||||||
-cat | Print NSI commands instead of sending them into the renderer. An example usage is converting a binary (or compressed) NSI into an human readable ASCII version:
| ||||||
-cat -binary | Outputs the NSI commands in binary format. For example:
| ||||||
-cat -gzip | Outputs the NSI file in compressed form. For example:
| ||||||
-v | Prints the current version of the renderer. | ||||||
| -h | Print Prints this help. |
Shell Return values
The renderdl executable will return one of the following values:
| Return Value | Description |
|---|---|
| 0 | No error. |
| 1 | Bad combination of parameters. An error message will explain why. |
| 199 | Option "licensing" "waitforlicense" 0 was used and no license was available |
| 255 | The NSI file specified on the command line could not be read. |
