VRayExporter

from tdw.add_ons.vray_exporter import VRayExporter

Render TDW scenes offline using V-Ray for enhanced photorealism.

This add-on converts scene-state data in TDW per communicate() call and saves it as .vrscene data, which can then be rendered with Chaos Vantage.

Rendering is typically done after the scene or trial is done, via self.launch_renderer(output_directory). The renderer can be a local or remote executable.

Class Variables

Variable Type Description Value
S3_ROOT str The S3 URL root. "https://tdw-public.s3.amazonaws.com/"
VRAY_EXPORT_RESOURCES_PATH Path The path to location of all downloaded and exported .vrscene files, maps etc. Path.home().joinpath("vray_export_resources")

Fields

  • vray_model_list The list of each model that can be rendered with VRay. The first time you run this add-on, it will query the S3 server for a list of models and save the result to ~/vray_export_resources/models.txt, which it will use for all subsequent runs.

  • commands These commands will be appended to the commands of the next communicate() call.

  • initialized If True, this module has been initialized.

Functions

__init__

VRayExporter(image_width, image_height, scene_name)

VRayExporter(image_width, image_height, scene_name, animate=False)

Parameter Type Default Description
image_width int The image width in pixels.
image_height int The image height in pixels.
scene_name str The scene name. This must match the scene being used in the TDW build, e.g. "tdw_room".
animate bool False If True, render an animation of each frame.

get_initialization_commands

self.get_initialization_commands()

This function gets called exactly once per add-on. To re-initialize, set self.initialized = False.

Returns: A list of commands that will initialize this add-on.

on_send

self.on_send(resp)

This is called within Controller.communicate(commands) after commands are sent to the build and a response is received.

Use this function to send commands to the build on the next Controller.communicate(commands) call, given the resp response. Any commands in the self.commands list will be sent on the next Controller.communicate(commands) call.

Parameter Type Default Description
resp List[bytes] The response from the build.

before_send

self.before_send(commands)

This is called within Controller.communicate(commands) before sending commands to the build. By default, this function doesn't do anything.

Parameter Type Default Description
commands List[dict] The commands that are about to be sent to the build.

get_early_initialization_commands

self.get_early_initialization_commands()

This function gets called exactly once per add-on. To re-initialize, set self.initialized = False.

These commands are added to the list being sent on communicate() before any other commands, including those added by the user and by other add-ons.

Usually, you shouldn't override this function. It is useful for a small number of add-ons, such as loading screens, which should initialize before anything else.

Returns: A list of commands that will initialize this add-on.

launch_renderer

self.launch_renderer(output_directory)

self.launch_renderer(output_directory, render_host="localhost", port=1204, renderer_path="C/Program Files/Chaos Group/Vantage/vantage_console.exe")

Launch Vantage in headless mode and render scene file, updating for animation if necessary.

Parameter Type Default Description
output_directory PATH The root output directory. If render_host == "localhost", this directory will be created if it doesn't already exist. On a remote server, the directory must already exist.
render_host str "localhost" The render host IP address.
port int 1204 The socket port for the render host. This is only used for remote SSHing.
renderer_path str "C/Program Files/Chaos Group/Vantage/vantage_console.exe" The file path to the Vantage console executable.
