Overview

DigitalRiseModel is MonoGame/FNA library that provides alternative API to XNA's 3D modelling. DigitalRiseModel has following features(that XNA lacks):

  • Construct 3D models in code
  • Load 3D models from GLTF/GLB in the run-time
  • Skeletal animation
  • Create 3D primitives(boxes, spheres, toruses, etc) in the run-time

It's important to note that DigitalRiseModel lacks functionality to render models. That is the responsibility of the developer.

However Samples section demonstrates how it could be done. It implements simple rendering engine that is based on XNA stock effects such as BasicEffect and SkinnedEffect.

Adding Reference For MonoGame

https://www.nuget.org/packages/DigitalRiseModel.MonoGame

Adding Reference For FNA

Clone following projects in one folder:

Link Description
https://github.com/FNA-XNA/FNA FNA
https://github.com/rds1983/XNAssets Assets management library
this repo

Now add every required project .FNA.Core.csproj to your project

Usage

Models are loaded through XNAssets.

Firstly create the AssetManager:

AssetManager assetManager = AssetManager.CreateFileAssetManager(@"c:\MyGame\Models");

Now load the model in the GLTF/GLB format:

DrModel model = assetManager.LoadModel(GraphicsDevice, "myModel.gltf")

The DrModel API is pretty much similar to XNA Model.

Samples

Right now, Samples is the best way to learn how to work with the library.

Name Description
BasicEngine Simple rendering engine that implements tree-like scenes and forward rendering, based on XNA stock effects such as BasicEffect and SkinnedEffect
ModelViewer Application to load and view 3D models in all supported formats. Skeletal animation is supported
ThirdPerson Application that demonstrates how simple third person controller could be done

Building From Source For MonoGame

Open DigitalRiseModel.MonoGame.sln in the IDE and run.
