Import3D

An asynchronous runtime 3D-model importer for Unity

Check out the changelog here.

⚠️ Development is paused ⚠️
No new features will be added or bugs fixed unless requested through an issue.
If you wish to fork this repository and continue the work, you are very welcome to do so.

Features

Import3D supports most common 3D-model formats as it uses Assimp internally.

Imports a scene's node-structure and geometry. Materials and textures are not imported yet.

Usage

Import functions are located on the static Import class.

// using At.Ac.FhStp.Import3D

// Import a single file asynchronously
var importedGameObject = await Import.SingleAsync(filePath);

Config

Some properties of the import process can be configured using a ImportConfig object, which can be passed as a second argument to all import functions. Refer to the ImportConfig XML-docs to learn more.

var config = ImportConfig.Default;
_ = await Import.SingleAsync(filePath, config);

Targets

Import3D uses the C-library Assimp internally. Because of this, not all target devices are supported out of the box as binaries for these platforms have to built and included in the package.

Currently Import3D supports the following platforms:

• Windows x64
• Android v7 / arm64

Installation

Best way to install is via OpenUPM using openupm add at.ac.fhstp.import3d.

You can also install manually as a git-dependency from https://github.com/fhstp/UnityImport3D.git. Make sure to add the following scoped-registry if you choose to do so:

{
  "name": "package.openupm.com",
  "url": "https://package.openupm.com",
  "scopes": [
    "com.openupm",
    "dev.comradevanti.opt-unity",
    "dev.comradevanti.rect-constraints",
    "org.nuget.comradevanti.csharptools.opt",
    "org.nuget.dev.comradevanti.nothing",
    "org.nuget.system.buffers",
    "org.nuget.system.collections.immutable",
    "org.nuget.system.memory",
    "org.nuget.system.numerics.vectors",
    "org.nuget.system.runtime.compilerservices.unsafe"
  ]
}

Samples

The package also includes a sample to show how the import process can be started. Have a look at /Samples~/ImportTester.

Roadmap

• Texture import
