# .PCD, .PLY, .LAS, .LAZ pointclouds

## Overview

This option allows you to upload point clouds as episodes to the platform without any annotations. All items from the input directory and its subdirectories will be uploaded to a single dataset. Supported formats are `.pcd`, `.ply`, `.las`, and `.laz`, and they are imported natively without conversion. If you need to preserve the directory structure, you can use the [Import Pointcloud Episodes](https://ecosystem.supervisely.com/apps/import-pointcloud-episode) application from the Supervisely Ecosystem.

## Format description

**Supported point cloud episode formats:** `.pcd`, `.ply`, `.las`, `.laz`.\
**With annotations:** No\
**Supported annotation format:** Not applicable.\
**Grouped by:** Any structure (will be uploaded to a single dataset).<br>

## Why native LAS/LAZ/PLY import matters

For point cloud episodes, Import Wizard loads `.las`, `.laz`, and `.ply` frames natively.

`PCD` is a simpler point cloud format. `LAS` / `LAZ` and many `PLY` variants can keep more useful source information per frame, so native import helps preserve the original sequence data.

Practical advantages for multi-frame projects:

* **More source attributes preserved across the sequence**: `LAS` / `LAZ` can keep LiDAR-specific fields such as intensity, return information, and classification. `PLY` can keep RGB, normals, and custom properties. Native import avoids simplifying those frames through an intermediate conversion step.
* **No conversion-related data loss**: when episodes are converted to `PCD`, source-specific fields may be lost or reduced. Native import keeps the original frame content intact.
* **Smaller files can improve sequence loading**: formats such as `LAZ` can be significantly smaller than converted `PCD`, which reduces transfer size and helps large multi-frame projects open faster.
* **Faster project startup**: there is no pre-conversion pipeline before frame mapping and sequence upload.
* **Immediate benefit from WebGPU rendering upgrades**: preserved attributes and dense frames can be rendered directly in the optimized pipeline, which is designed for large scenes and high point counts.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.supervisely.com/import-and-export/import/supported-annotation-formats/pointcloud_episodes/point_clouds_episodes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
