Ange 3D Filspararalternativ i C#

Översikt

Den här artikeln förklarar hur du kan spara 3D filer i olika format Efter att ha laddat dem i Sceneobjekt med C#. Genom att ladda och spara kan du utföra antal olika konverteringar, t.ex.

  • Konvertera FBX till X i C#
  • Konvertera GLTF till OBJ i C#
  • Konvertera OBJ till X i C#
  • Konvertera STL till OBJ i C#
  • Konvertera RVM till 3DS i C#

3D Filspararalternativ

Det finns flera överbelastningar med Scene.Save som accepterar ett SparaOptions-objekt. Detta bör vara ett föremål för en klass som härrör från klassen SaveOptions. Varje format spara har en motsvarande klass som innehåller sparalternativ för det spara formatet, till exempel, det finns ColladaSaveOptions för FileFormat.Collada spara formatet.

Användning av Collada Spara inställningarna

C#-koden nedan visar hur sparalternativ ska ställas innan en 3D-fil sparas i Collada-format.

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
ColladaSaveOptions saveColladaopts = new ColladaSaveOptions();
// Generates indented XML document
saveColladaopts.Indented = true;
// The style of node transformation
saveColladaopts.TransformStyle = ColladaTransformStyle.Matrix;
// Configure the lookup paths to allow importer to find external dependencies.
saveColladaopts.LookupPaths = new List<string>(new string[] { "textures" });

Användning av Discreet3DS Spara inställningarna

C#-koden nedan visar hur sparalternativ ska ställas innan en 3D-fil sparas i ett diskret 3DS-format.

// Initialize an object
Discreet3dsSaveOptions saveOpts = new Discreet3dsSaveOptions();
// The start base for generating new name for duplicated names.
saveOpts.DuplicatedNameCounterBase = 2;
// The format of the duplicated counter.
saveOpts.DuplicatedNameCounterFormat = "NameFormat";
// The separator between object's name and the duplicated counter.
saveOpts.DuplicatedNameSeparator = "Separator";
// Allows to export cameras
saveOpts.ExportCamera = true;
// Allows to export light
saveOpts.ExportLight = true;
// Flip the coordinate system
saveOpts.FlipCoordinateSystem = true;
// Prefer to use gamma-corrected color if a 3ds file provides both original color and gamma-corrected color.
saveOpts.GammaCorrectedColor = true;
// Use high-precise color which each color channel will use 32bit float.
saveOpts.HighPreciseColor = true;

// Configure the look up paths to allow importer to find external dependencies.
saveOpts.LookupPaths = new List<string>(new string[] { "textures" });
// Generates a video object for texture.
saveOpts.VideoForTexture = true;

FBXSaveOptions exponerar också EnableCompression egenskap som kan användas för att komprimera större binärdata i FBX-filen. Standardvärdet för den här egenskapen är sant. Nedan förklarar kod snippet hur du kan arbeta med denna egendom medan du sparar en scen.

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET

            // Load a 3D document into Aspose.3D
            Scene scene = Scene.FromFile"document.fbx");

// Save 3D Scene
scene.Save("prettyPrintInGltfSaveOption.gltf", opt);

Spara beroenden för en 3D i det verkliga filsystemet

Utvecklare kan behöva spara alla 3D-scener i det riktiga filsystemet. De kan definiera sökvägen för en lokal katalog, spara i MemoryFileSystem- objektet eller helt enkelt förkasta beroenden. Egenskapen FileSystem läggs till i alla spara alternativklasser.

// Initialize Scene object
Scene scene = new Scene();
// Create a child node
scene.RootNode.CreateChildNode("sphere", new Sphere()).Material = new PhongMaterial();
// Set saving options
ObjSaveOptions opt = new ObjSaveOptions();
opt.FileSystem = new DummyFileSystem();
// Save 3D scene
scene.Save("DiscardSavingMaterial_out.obj", opt);

scene.RootNode.CreateChildNode("sphere", new Sphere()).Material = new PhongMaterial();
// Set saving options
ObjSaveOptions opt = new ObjSaveOptions();
opt.FileSystem = new LocalFileSystem("local_dir/");
// Save 3D scene
scene.Save"SavingDependenciesInLocalDirectory_out.obj", opt);

Spara beroende i MemoryFileSystem- objekt

var node = scene.RootNode.CreateChildNode("Box", new Box());
node.SetProperty("rvm:Refno", "=3462123");
node.SetProperty("rvm:Description", "This is the description of the box");
//The RVM attribute's prefix is rvm:, all properties that starts with rvm: will be exported to .att file(the prefix will be removed)
var opt = new RvmSaveOptions() { AttributePrefix = "rvm:", ExportAttributes = true };
scene.Save( "test.rvm", opt);
