User Account
User
To use 3dverse platform for real-time rendering service, users need to create an account. Depending on the plan selected features can be available or not. Basic plans have limited upload, sharing and edition capabilities.
Workspace
Once a user has an account, he can create workspaces to organise his work.
The user can then upload scenes (from common 3D files) or textures in a workspace.
You can share each workspace with other users, or keep it private.
Client
Clients are applications running a real-time rendering session on the user device, such as:
- Laptop
- Tablet
- PC
- Cell phone
- Hololens
Depending on the user account plan, a user can launch one or more client session.
Real time rendering: Sessions and Sharing
Real time rendering sessions
To visualize a scene, a client application needs to start a real time rendering session.
Depending on the user subscription plan and the client application,
other users can then join this session either as a simple spectator or as an editor.
In a single session, a user can have one or more viewport looking at different perspective of the scene, the same
is also applicable when there are multiple users in a session.
Sharing
Workspace can be share with other users. All the scenes and assets within a workspace will be
available to the users in the shared group.
Users in the shared group will also see active sessions within the workspace and will be able
to join these active sessions.
You can share a session to an anonymous user by getting a guestToken. The connection
lifetime of this token is limited to the session lifetime.
When sharing a session, users can hook on another user's camera so their share the same point of view as this user
navigates through the scene.
When users in a session have edition rights, they can simultaneously modify the scene and immediately visualize their work and
the work of the others in the scene, avoiding conflict in the edition.
Definitions
Display
The display is the real time rendering area size. It's composed of at least one viewport.
Viewport
A viewport is a framed area on the display having its own camera or attached to another user camera.
Camera
A camera controls the view within the viewport.
Asset
An asset is a single logical piece of data:
| Asset type | Description |
|---|---|
| Scene | Describes how the different entities of a virtual world are organized. An entity can reference any asset type. |
| Mesh | Represents a polygonal 3D model composed of vertices. Each vertex can have multiple attributes. Vertices are indexed by 3 to form a list of triangles. 3dverse has its own format for this asset type. |
| Material | List of attributes describing how a surface reacts to lighting. Those attributes can be floating numbers, vectors, references to textures, etc. A material references a shader. |
| Animation | Represents how the transforms of a skeleton should evolve through time. It references a skeleton. |
| Animation graph | Represents an animation state machine. |
| Skeleton | Used for skinning a mesh, such as deforming the vertices of the mesh to reflect the transform of the bones that compose the skeleton. It represents a series of hierarchical transforms. |
| Texture | Chain of 2D images compressed and optimized for real-time rendering. The chain, called mipmaps, consists of the same image having its resolution halved as you go down the chain. |
| Texture 1D | Texture data that has a single dimension. |
| Texture 3D | Texture data that has three dimensions. |
| Cubemap | A textured cube. It references 6 textures, each one for each face of the cube. |
| Volume material | Represents the application of an opacity lookup table on a volume. |
| Shader | A shader is a program that compiles and runs on the GPU. |
| Voxel | Represents a 3D volume defining densities in space. |
| Lookup table (LUT) | Represents the way how to visualize a Voxel in 3D by assigning a material to some density values. |
| Render graph | Contains the rendering properties of other assets in a scene. |
| Sound | Represents an audio recording. |
Entity
An entity is an aggregate of components.
Scene
A scene contains a collection of one or more assets that are rendered in real time from the requested camera point of view.
The user can also create a new empty scene and, using the asset browser, simply drag and drop assets
from other scene or workspace to compose his new scene.
