# Get3D Engine ## 1 Principles of Engine Get3D Engine features a monitoring function for quickly checking engine status, utilization, and modifying settings. Users can adjust configurations such as the "job queue directory," "cache directory," "engine capabilities," and control the engine with "start/stop" options. * **Job Queue Directory:** Defines the job path of the current project, the jobs submitted by the current project are stored under this path, waiting for the engine to accept the processing. * **Cache Directory:** Stores temporary files during job processing, the path needs to be set to the local disk. In the Get3D Mapper main interface, the **Job Queue Directory** is used to store submitted jobs. The Get3D Engine retrieves jobs submitted by Get3D Mapper from the **Job Queue Directory**. The engine reads job information (e.g., AT\_job/Reconstruction\_job), processes the jobs, and outputs the results.

## 2 Engine Monitoring Panel The Engine Monitoring Panel at the bottom of Get3D Mapper displays the job queue and engine status.

Function	Description
Job Queue Directory	Current job queue directory, where the project's jobs are stored.
Engines	The number of engines in the current job queue directory.
Running Engines	The number of running engines in the current job queue directory.
Refresh	Refresh engine status
Job Queue Setting	Set the job queue for project. Cannot be changed when engine is running.
Engine Setting	Set the job queue for the engine to receive jobs.
Start Local Engine	Start the local engine.
Local Engine	The status of the local engine includes four states: None: Engine is not started. Pending: Engine is waiting to accept jobs. Running: Engine is processing jobs Inconsistent path: The engine's job queue directory differs from the project job queue.

## 3 Get3D Engine Interface Get3D Engine interface has two module: Engine Information and Engine Log

The Engine Information module contains host name, IP address, engine version, engine status, engine capability, job queue directory, cache directory, cache space, CPU utilization, memory utilization, and GPU memory utilization.

Function	Description
Host Name	Device name
IP Address	Device IP address
Engine Version	Get3D Engine version
Engine Status	Stop(closed), Waiting(opened without accepting a task), Running(task running), Abnormal (exited abnormally)
Engine Capability	Set the engine capability, the engine only processes jobs with this processing capability. AT: extract points, matching, small block bundle, overall bundle; Reconstruction
Job Queue Directory	Set directory for engine to receive jobs
Cache Directory	Set engine cache directory
Cache Space Remaining	Project cache disk, used space/hard drive space
CPU Utilization	CPU usage percentage
Memory Utilization	Memory, used memory/node memory
GPU Utilization	Video memory, used video memory/node video memory

## 4 Get3D Engine Setting The engine setting function is in the node information list, right-click to jump out, the setting function is shown in the figure below:

Function	Description
Refresh Engine Information	Refresh engine CPU, memory, GPU utilization, engine status, cache directory space remaining information
Modify Job Queue Directory	Modify the job queue directory of engine
Modify Cache Directory	Modify the cache directory of project
Set Engine Capabilities	Acquire the capability to receive AT/reconstruction jobs
Start Engine	Start accepting jobs
Stop Engine	Stop accepting jobs
