Transformation

All Objects in Incari exist in 3D space, and have a set of Attributes to define their Transformation data. Transformation is divided into three Vector3 type Attributes: Position, Rotation, and Scale.

Position

Position is defined by three values, representing each of the three axes of a three dimensional Cartesian coordinate system.

In most 2D graphics applications, you will typically see a coordinate system with the origin (0,0) at the top-left corner of a document, and the X value increasing from left-to-right and the Y value increasing from top-to-bottom.

In Incari, coordinates are in 3D Euclidean space, with the origin (0, 0, 0) at the center, and the x value increasing from center-to-right, the y value increasing from center-to-top and the z value increasing from center-to-front.

Any point in space can be determined by these x, y, and z values.

Rotation

The Rotation Attribute represents the Euler angle of rotation of an Object along each of its axes. The Object is rotated in local space, meaning that any adjustments will be made along its own axes, not the axes of the Scene itself. Axes can be thought of as being like three skewers, going through the Object and intersecting at the Object's Pivot Point.

Scale

Scale multiplies the size of an Object along its axes, relative to its Origin. By default, Scale is set to 1, 1, 1, meaning that it is at 100% of its size on all axes.
