Blundergat.Io

A import/export library for 3D assets written using .NET Core 3.1. Supported formats are Lightwave OBJ (.obj) and Polygon File Format PLY (.ply). This is the core read/write library used in the Blundergat framework. This project was helped by both Meshellator (https://github.com/tgjones/meshellator) and PlyImporter (https://github.com/3DBear/PlyImporter) for the BinaryLittleEndian support.

How do I use this to import assets?

Call without logging

var importerExporter = new PlyAssetImporterExporter(settings, null);
var scene = await importerExporter.ImportFileAsync(filePath);

How do I use this to export assets?

Call without logging, assume we already haveIPointCloud pointCloud

var scene = PointCloudToSceneAdapter.GenerateSceneFromPointCloud(pointCloud);

var settings = new IoSettings(); // Neet to implement a IIoSettings class!
settings.DefaultPlyFileFormat = plyFileFormat;

var importerExporter = new PlyAssetImporterExporter(settings, null);
await importerExporter.ExportFileAsync(scene, filePath, true);

Setup to use a factory to handle multiple asset types at runtime

var assetImporterExporterFactory = AssetImporterExporterFactory.Instance(
    new List<(AssetImporterExporterType, IAssetImporterExporter)>()
        {
            (AssetImporterExporterType.Ply, new PlyAssetImporterExporter(settings, null)),
            (AssetImporterExporterType.Obj, new ObjAssetImporterExporter(settings, null))
        });

Can get the importer/exporter using enum value

var assetImporterExporter = assetImporterExporterFactory.GetImporterExporter(AssetImporterExporterType.Ply);

Or a file path string

var assetImporterExporter = assetImporterExporterFactory.GetImporterExporter(filePath);
