Aspose.3D FOSS for .NET

API reference for Aspose.3D.Converter 1.0.0 (.NET 10.0+, MIT license).

All classes reside in the Aspose.ThreeD root namespace. The root using directive is:

using Aspose.ThreeD;

C# naming convention: All properties use standard C# property syntax. For example, use scene.RootNode instead of scene.getRootNode(), and transform.Translation = ... instead of transform.setTranslation(...). Vector3, Vector4, Quaternion, Matrix4, and FVector types use public fields (v.X, v.Y, v.Z) for component access.

Core Scene Graph

Class	Description
`Scene`	Top-level container for all 3D scene data. Holds the root node, asset metadata, and animation clips. Exposes `Open()` and `Save()` as the primary I/O entry points.
`Node`	A named node in the scene hierarchy. Owns a list of child nodes and a list of attached `Entity` objects such as meshes, cameras, and lights. Carries a local `Transform`.
`Entity`	Abstract base class for all objects that can be attached to a `Node`. Provides name and identity but no geometry of its own.
`SceneObject`	Base class shared by `Node` and `Entity`. Provides the property collection interface used for user-defined metadata.
`A3DObject`	Root base class for all Aspose.3D managed objects. Exposes the `Name` property and the `Properties` collection.
`INamedObject`	Interface that guarantees a `Name` property. Implemented by `Node`, `Entity`, and several format-specific descriptor types.

Geometry and Mesh

Class	Description
`Mesh`	Polygon mesh entity. Stores control points (vertex positions as `Vector4`), polygon face lists (lists of control-point indices), and vertex element layers (normals, UVs, vertex colours).
`Geometry`	Abstract base for mesh-like geometry types. Defines the control-point array and the collection of `VertexElement` layers. `Mesh` inherits from `Geometry`.
`VertexElement`	Abstract base for a data layer attached to geometry (normals, UVs, colours, etc.). Carries `MappingMode`, `ReferenceMode`, and a data list.
`VertexElementNormal`	Stores one normal vector per vertex or per polygon corner, depending on mapping mode.
`VertexElementUV`	Stores texture-coordinate pairs (`Vector2`) per vertex or per polygon corner.
`VertexElementVertexColor`	Stores per-vertex or per-corner RGBA colour data as `Vector4`.

Built-In Primitives

Class	Description
`Box`	Parametric axis-aligned box with configurable width, height, and depth. Can be attached to a `Node` directly or converted to `Mesh` via `ToMesh()`.
`Sphere`	Parametric sphere with configurable radius. Supports `ToMesh()` conversion.
`Cylinder`	Parametric cylinder with configurable top radius, bottom radius, and height. Supports `ToMesh()` conversion.

Transform and Spatial

Class	Description
`Transform`	Local transformation attached to a `Node`. Provides `Translation` (FVector3), `Rotation` (Quaternion), `Scale` (FVector3), and `Matrix` (Matrix4) properties.
`GlobalTransform`	Read-only view of a node’s world-space transformation matrix after composing all ancestor transforms. Accessed via `node.GlobalTransform`. Exposes a single `Matrix` property.
`AssetInfo`	Metadata block attached to a `Scene`. Inherits from `A3DObject` providing `Name` and `Properties`. No additional properties are defined in this edition.

Materials and Shading

Class	Description
`Material`	Abstract base class for all material types. Provides a name and a property collection.
`LambertMaterial`	Classic diffuse-only material with `Ambient`, `Diffuse`, `Emissive`, `Reflective`, `Transparency`, and `Texture` properties. Namespace: `Aspose.ThreeD.Shading`.
`PhongMaterial`	Extends Lambert with `Specular`, `Shininess`, and `SpecularPower` properties. Namespace: `Aspose.ThreeD.Shading`.
`PbrMaterial`	Physically Based Rendering material with `BaseColor`, `Metallic`, `Roughness`, `Occlusion`, and texture slot properties. Namespace: `Aspose.ThreeD.Shading`.

Camera

Class	Description
`Camera`	Camera entity. Inherits from `Frustum`. Attached to a `Node` to define viewpoint transforms. No format-specific properties are exposed in this edition.

Math Utilities

Class	Description
`Vector2`	Single-precision 2-component vector (`X`, `Y`). Used for UV texture coordinates.
`Vector3`	Single-precision 3-component vector (`X`, `Y`, `Z`). General-purpose spatial vector.
`Vector4`	Single-precision 4-component vector (`X`, `Y`, `Z`, `W`). Used for control points and normal data.
`FVector3`	Single-precision 3-component float vector. Used by `Transform.Translation` and `Transform.Scale`.
`FVector4`	Single-precision 4-component float vector.
`Quaternion`	Unit quaternion for representing rotations (`W`, `X`, `Y`, `Z`). Used by `Transform.Rotation`.
`Matrix4`	4x4 transformation matrix. Used for world/local transform computations and by `GlobalTransform.Matrix`.
`BoundingBox`	Axis-aligned bounding box defined by `Minimum` and `Maximum` `FVector3` corners.

Animation

Class	Description
`AnimationClip`	Named container for an animation range. A `Scene` may hold multiple clips. Declaration stub — keyframe data and playback are not yet implemented.

Format I/O

Symbol	Description
`Scene.Open(path)`	Opens a file, detects the format from the extension, and populates the scene.
`Scene.Open(path, options)`	Opens a file with format-specific `LoadOptions`.
`Scene.Open(stream)`	Opens from a stream, auto-detecting the format from content.
`Scene.Open(stream, options)`	Opens from a stream with format-specific `LoadOptions`.
`Scene.Save(path)`	Saves the scene to a file; format inferred from extension.
`Scene.Save(path, options)`	Saves with format-specific `SaveOptions`.
`Scene.Save(stream, options)`	Saves to a stream with format-specific `SaveOptions`.
`FileFormat`	Registry of supported file formats. Contains entries such as `FileFormat.WavefrontOBJ`, `FileFormat.GLTF2`, `FileFormat.FBX7400ASCII`.
`IOService`	Internal I/O abstraction. Provides `DetectFormat()` for stream-based format detection.
`LoadOptions`	Base class for format-specific load options.
`SaveOptions`	Base class for format-specific save options.

OBJ Format

Class	Description
`ObjLoadOptions`	Load options for Wavefront OBJ files.
`ObjSaveOptions`	Save options for Wavefront OBJ output.

STL Format

Class	Description
`StlLoadOptions`	Load options for STL files.
`StlSaveOptions`	Save options for STL output.

glTF Format

Class	Description
`GltfLoadOptions`	Load options for glTF 2.0 and GLB files.
`GltfSaveOptions`	Save options for glTF 2.0 and GLB output. No format-specific properties are exposed in this edition; use `.glb` extension for binary output.

FBX Format

Class	Description
`FbxLoadOptions`	Load options for FBX files.
`FbxSaveOptions`	Save options for FBX output. Use `IsAscii` to toggle ASCII/binary mode.

`Axis`	Identifies a coordinate axis: `XAxis`, `YAxis`, `ZAxis`.
`CoordinateSystem`	Specifies handedness convention: `RightHand` or `LeftHand`.

Properties System

Class	Description
`Property`	A single named typed property on an `A3DObject`.
`PropertyCollection`	Iterable collection of `Property` objects attached to an `A3DObject`.
