The Transform component is not shareable between multiple Entity's. The transformation is held as vector3d scale, quaternion rotation and vector3d translation components. The transformations are applied to the mesh in that order. When Transform::matrix property is set, it is decomposed to these transform components and corresponding transform signals are emitted.
Several helper functions are provided to set up the Transform; fromAxisAndAngle and fromAxesAndAngles can be used to set the rotation around specific axes, fromEulerAngles can be used to set the rotation based on euler angles and rotateAround can be used to rotate the object around specific point relative to local origin.
|
matrix : matrix4x4 |
Holds the matrix4x4 of the transform.
Note: When the matrix property is set, it is decomposed to translation, rotation and scale components.
|
rotation : quaternion |
Holds the rotation of the transform as quaternion.
|
rotationX : real |
Holds the x rotation of the transform as Euler angle.
|
rotationY : real |
Holds the y rotation of the transform as Euler angle.
|
rotationZ : real |
Holds the z rotation of the transform as Euler angle.
|
scale : real |
Holds the uniform scale of the transform. If the scale has been set with scale3D, holds the x value only.
|
scale3D : vector3d |
Holds the scale of the transform as vector3d.
|
translation : vector3d |
Holds the translation of the transform as vector3d.

|
quaternion fromAxesAndAngles(vector3d axis1, real angle1, vector3d axis2, real angle2) |
Creates a quaternion from axis1, angle1, axis2, and angle2. Returns the resulting quaternion.
|
quaternion fromAxisAndAngle(real x, real y, real z, real angle) |
Creates a quaternion from x, y, z, and angle. Returns the resulting quaternion.
|
quaternion fromAxisAndAngle(vector3d axis, real angle) |

|
quaternion fromEulerAngles(real pitch, real yaw, real roll) |
Creates a quaternion from pitch, yaw, and roll. Returns the resulting quaternion.
|
quaternion fromEulerAngles(vector3d eulerAngles) |
Creates a quaternion from eulerAngles. Returns the resulting quaternion.
Creates a rotation matrix from axis and angle around point relative to local origin. Returns the resulting matrix4x4.
