API changes

Added class Aspose.ThreeD.Profiles.FontFile

Added class Aspose.ThreeD.Profiles.Text

A FontFile can be used with Text to define profile from a string, then it can be used by other procedural modeling classes like LinearExtrusion

	// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
	// Load font from bytes
	var font = FontFile.Parse(File.ReadAllBytes(@"test-font.otf"));
	// Create a Text profile
	var text = new Text()
	{
	Font = font,
	Content = "Hello World",
	FontSize = 10
	};
	// Extrude the profile to give it a thickness.
	var linear = new LinearExtrusion(text, 10).ToMesh();
	// create a scene from the mesh and save it to stl file
	var scene = new Scene(linear);
	scene.Save(@"test.stl");

Added members to class Aspose.ThreeD.Formats.DracoSaveOptions, Aspose.ThreeD.Formats.GltfSaveOptions, Aspose.ThreeD.Formats.ObjSaveOptions:

Set this to true to make the exporter rescale position coordinates of meshes by Scene.AssetInfo.UnitScaleFactor, this option works for Gltf/Obj/Draco file.

        /// <summary>
        /// Apply <see cref="AssetInfo.UnitScaleFactor"/> to the mesh.
        /// Default value is false.
        /// </summary>
        bool ApplyUnitScale{ get;set;}

Sample code

        var s = new Scene("test.fbx");
        var opt = new ObjSaveOptions() { ApplyUnitScale = true };
        s.Save("output.glb", opt);
