Synopsis
The plane design describes an infinite, two-dimensional plane that is oriented with respect to its center point and a normal vector. The local X- and Y-axis of the plane are only constrained to be orthogonal to each other and the normal: vector of the plane, no other direction is guaranteed. The plane is displayed as a small rectangle and a coordinate system and is often used as a reference to orient and position other geometry.
Canonicals
| Name | Type | Description |
|---|---|---|
| origin | point | Origin point of the plane. |
| normal | vector | Normal vector of the plane. |
Parameters
| Name | Type | Description |
|---|---|---|
| size | number | Display length of line representing the plane. |
| ray | part | Ray part that describes both the origin point and normal vector of the new plane. The origin of the plane is set to the origin of the ray. The normal of the plane is set to the direction vector of the ray parameter. |
Group Rules
<normal> Calculates the localFrame from the normal vector. The normal is used as the localFrame's Z axis, the X axis is a random perpendicular vector to the Z axis, and the Y axis is perpendicular to both the Z and X axes.
<ray> Calculates the origin from the ray's origin rule and the normal from the ray's direction rule.
