flutter_pcd_view 0.1.4

Flutter plugin for viewing PCD point clouds with Rust parsing and native Android/iOS rendering.

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: ^0.1.2

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.
