This command is used to render frames of a 3D scene in Blender, a popular open-source 3D modeling and animation software.
Let's break down the command:
-
blender
: This is the main command to run Blender from the command line. -
--background
: This option tells Blender to run in background mode, meaning it starts without opening the user interface. This is useful for running Blender without any user interaction in automated rendering processes. -
${filename}.blend
: This is the path and filename of the .blend file to be rendered. The${filename}
variable indicates that it should be replaced with the actual filename before executing the command. -
--render-output
: This specifies the output directory where the rendered frames will be saved. The//
prefix specifies that the path is relative to the location of the .blend file. The${output_directory}
variable is used to represent the actual output directory. -
--render-frame
: This is used to specify the frame(s) to render. In this case, two frame numbers are specified:${JPEG}
and${-2}
. -
${JPEG}
: This is a variable used to represent a specific frame number. The value of${JPEG}
needs to be replaced with an actual frame number before executing the command. -
${-2}
: This is another variable representing a frame number. The-${-2}
syntax is a bit unusual, as it's trying to represent a negative frame number. Similarly, the actual value for${-2}
needs to be substituted before running the command.
In summary, this command is telling Blender to render specific frames from a .blend file (${filename}.blend) in background mode (--background), outputting the rendered frames to a specified directory (--render-output), and specifying the frames to render (${JPEG} and ${-2}). The variables need to be replaced with their actual values before executing the command.
