Flutter PCD View

flutter_pcd_view is a Flutter plugin for viewing PCD point cloud files on Android and iOS. It uses Rust for PCD parsing and native rendering backends for interactive display: OpenGL ES on Android and Metal on iOS.

Features

Parse ASCII and binary PCD files.
Display XYZ, XYZRGB, and XYZHSV point clouds.
Render with mobile native textures on Android and iOS.
Rotate, zoom, and pan with Flutter gestures.
Optional point budget, voxel sampling, deduplication, outlier removal, grid, axes, and point color settings.

Platform Support

Current rendering support is Android and iOS only. Other Flutter platforms return an unsupported-platform state instead of rendering a point cloud.

Installation

dependencies:
  flutter_pcd_view: ^0.1.6

Quick Start

Import the main widget API:

import 'package:flutter_pcd_view/flutter_pcd_view.dart';

Use the default viewer directly:

PcdView.fromFile(filePath: '/path/to/file.pcd')

The parser initializes automatically when the viewer loads a file. For in-memory points, use:

PcdView.fromPoints(points: points)

Optional Configuration

Defaults are intended to work without extra setup. Add a controller or config only when the host app needs custom camera state or rendering options:

final controller = NativeCameraController();

PcdView.fromFile(
  filePath: '/path/to/file.pcd',
  controller: controller,
  config: const ViewerConfig(
    pointSize: 2,
    showAxes: true,
    performance: PerformanceConfig(
      nativePointBudget: 150000,
      nativeRenderScale: 2,
    ),
  ),
)

Example

See the example/ directory for a complete Flutter app with bundled sample PCD files, file picking, settings, and native renderer status.
