Any perpendicular.
Perpendicular. If one line is normal to another, then they are at right angles to each other.
Being at a right angle to a specific plane.
a line which goes through the centre of a circle and through the point of tangency
a piece of data showing the way in which light interacts with a surface at a given point
a unit vector that defines the orientation of a surface such as a quadrilateral or triangle
a vector pointing straight out from a polygon, giving the direction that polygon is facing
in POV-Ray, surface effects simulated on objects by manipulation of light rays. ( Language Reference) ( Tutorial) ( Exploration Tool) Object: a thing in space. Objects are what you see when you render a scene. Examples of objects are spheres, boxes, and CSG objects. ( Language Reference)
A three-component plane equation that defines the angular orientation, but not position, of a plane or surface.
The line of sight or direction at right angles to the plane of a mirror.
The normal to a surface is an imaginary line at right angles to the surface. Reflecting Light
A line at right angles angles to the surface of a mirror or other optical device.
The perpendicular to a surface. Used for angle measurements.
A line constructed perpendicular to the surface
The line perpendicular to a surface. There is only one normal for any given surface.
an imaginary line perpendicular to a surface; used in determining the direction taken by reflected or refracted light
In modeling, the directional line perpendicular to a surface. Polygon normals indicate the orientation of polygonal faces. Because shaded (or rendered) faces are visible only when the normals are facing towards the viewer, it is sometimes necessary to reverse a normal to correct a face's orientation.
Perpendicular, or a line perpendicular. The normal to a surface is a line perpendicular to the surface at the point of intersection. If the surface is not flat, the normal is perpendicular to a tangent line drawn through the point of intersection. Interestingly, perpendicular is the original meaning of the word "normal". The common usage meaning "ordinary" came about because ordinary things are often perpendicular. The normal lines to a bumpy surface are shown on this page of this module.
Perpendicular to the barrier which a wave hits. An immaginary line of reference.
A vector that extends outward perpendicular to a graphic element. NURBS
a three dimensional vector that is perpendicular to a surface at the point where it intersects with a plane tangent to the surface
(a.) Perpendicular. (n.) A normalized vector.
In mathematics, a normal line is perpendicular (at right angles) to the tangent of a curve.
at right angles, perpendicular. The line that is normal to the plane is a right angles to any line that lies in the plane
a construction line drawn perpendicular (90°) to the surface at the point of incidence.
