Cast.NET is a .NET library for reading and writing cast files. Cast is an open source container for models, animations, materials and more designed by DTZxPorter.
Cast.NET provides you with the ability the read and write these files in an easy and efficient way in .NET. It provides high level access to cast files while also allowing you to work with them in any way you want.
Cast.NET requires .NET 6.0 and has been tested on both Windows and Linux.
Documentation is available here: https://scobalula.github.io/Cast.NET/. Documentation for Cast.NET is constantly evolving, if you want to help out, please feel free to file a PR!
A quick example of loading a model and printing its materials:
var cast = CastReader.Load("your_cast_file.cast");
var root = cast.RootNodes[0];
foreach (var model in root.EnumerateChildrenOfType<ModelNode>())
{
if(model.Skeleton is not null)
{
foreach (var bone in model.Skeleton.EnumerateBones())
{
Console.WriteLine(bone.Name);
}
}
foreach (var material in model.EnumerateChildrenOfType<MaterialNode>())
{
Console.WriteLine(material.Name);
Console.WriteLine($"\tAlbedoFile: {material.AlbedoFile?.Path}");
Console.WriteLine($"\tDiffuseFile: {material.DiffuseFile?.Path}");
Console.WriteLine($"\tNormalFile: {material.NormalFile?.Path}");
Console.WriteLine($"\tSpecularFile: {material.SpecularFile?.Path}");
Console.WriteLine($"\tEmissiveFile: {material.EmissiveFile?.Path}");
Console.WriteLine($"\tGlossFile: {material.GlossFile?.Path}");
Console.WriteLine($"\tRoughnessFile: {material.RoughnessFile?.Path}");
Console.WriteLine($"\tAmbientOcclusionFile: {material.AmbientOcclusionFile?.Path}");
Console.WriteLine($"\tCavityFile: {material.CavityFile?.Path}");
}
}A quick example of building a simple skeleton only model:
using System.Numerics;
var root = new CastNode(CastNodeIdentifier.Root);
var model = root.AddNode<ModelNode>();
var skeleton = model.AddNode<SkeletonNode>();
for (int i = 0; i < 16; i++)
{
var bone = skeleton.AddNode<BoneNode>();
bone.AddString("n", $"bone_{i}");
bone.AddValue("p", (uint)(i - 1));
bone.AddValue("lp", new Vector3(0, 0, i));
bone.AddValue("lr", new Vector4(0, 0, 0, 1));
}
CastWriter.Save("your_cast_file.cast", root);More in-depth examples are included in the source code, these include a basic Gltf to cast converter and a simple project that dumps all information in the cast file to a text file. The examples are constantly evolving with more being added as time goes on. If you're interested in helping out, feel free to file a PR with an example to help other learn how to use the library.
