Transform

The transform describes an entity's transformation. This page outlines the transform structure of the VEML specification.

Transform Types

• Scale Transform: Contains position, rotation, and scale.
• Size Transform: Contains position, rotation, and size.
• Canvas Transform: Contains position-percent and size-percent.

v1.0+ Scale Transform

A transform for an entity represented by a position, rotation, and scale.

• position - Position of the entity. Required.

  • x: float - X component of the entity's position.

  • y: float - Y component of the entity's position.

  • z: float - Z component of the entity's position.

• rotation - Rotation of the entity. Required.

  • x: float - X component of the entity's quaternion rotation.

  • y: float - Y component of the entity's quaternion rotation.

  • z: float - Z component of the entity's quaternion rotation.

  • w: float - W component of the entity's quaternion rotation.

• scale - Scale of the entity. Can only be used if "size" is excluded.

  • x: float - X component of the entity's scale.

  • y: float - Y component of the entity's scale.

  • z: float - Z component of the entity's scale.

v1.0+ Size Transform

A transform for an entity represented by a position, rotation, and size.

• position - Position of the entity. Required.

  • x: float - X component of the entity's position.

  • y: float - Y component of the entity's position.

  • z: float - Z component of the entity's position.

• rotation - Rotation of the entity. Required.

  • x: float - X component of the entity's quaternion rotation.

  • y: float - Y component of the entity's quaternion rotation.

  • z: float - Z component of the entity's quaternion rotation.

  • w: float - W component of the entity's quaternion rotation.

• size - Size of the entity. Can only be used if "scale" is excluded.

  • x: float - X component of the entity's size (in meters).

  • y: float - Y component of the entity's size (in meters).

  • z: float - Z component of the entity's size (in meters).

v1.0+ Canvas Transform

A transform for a UI element entity represented by a position, rotation, and scale.

• position-percent - Position of the entity as a percentage of the canvas (measured from top right corner). Required.

  • x: float - X component of the entity's position.

  • y: float - Y component of the entity's position.

• size-percent - Size of the entity as a percentage of the canvas.

  • x: float - X component of the entity's size.

  • y: float - Y component of the entity's size.
