How to get a reflection vector? - Mathematics Stack Exchange
WEBMultiplying by n turns this scalar d ⋅ n into a vector of length d along the direction n. If you substracted this from d, you would remove all of the n-direction character from d (i.e., it would be perpendicular to n and would be parallel to b in the diagram).
WEBWe will start examining that situation in 2D (Fig. 1), a ray reflected off of a line or curve, and later extend it to 3D, a ray reflecting off of a surface. The Reflection Theorem illustrates a modern use of the projection vector.
Why does the formula for calculating a reflection vector work?
WEBThe formula for calculating a reflection vector is as follows: $$ R = V - 2N(V\cdot N) $$ Where V is the incident vector and N is the normal vector on the plane in question. Why does this formula work?
WEBthe problem of reflection and transmission. To visualize mirror-like obj. cts, you need to reflect your viewing ra. s. To simulate a lens, you need refraction. While most people have heard of the law of reflection and Snell’s law, they often have difficulties with actually calculating the direction.
Glide reflection - Wikipedia
WEBA glide reflection is the composition of a reflection across a line and a translation parallel to the line. This footprint trail has glide-reflection symmetry. Applying the glide reflection maps each left footprint into a right footprint and vice versa.

WEBHere are the components that are illustrated in figure 1: I → - The incident vector. R → - The reflected vector. θ - The angle of incidence is equal to the angle of reflection. This angle is measured from the plane’s normal vector. N → - The normal vector of the plane.

WEBA glide reflection is the composition of a reflection, and a translation in a vector parallel to the line of reflection. This image gets the idea across: (The figure is from Richard Brown's excellent but dated and out-of-print Transformational Geometry )
Reflecting a vector over another line - Mathematics Stack Exchange
WEBApr 18, 2017 · The incoming normal can be read from the equation: $(-1/3,-1)$, or $(1,3)$ to simplify the arithmetic. The reflection formula produces $\left(\frac{41}{13},-\frac3{13}\right)$, which you can verify is perpendicular to the vector $\mathbf r$ computed previously.
Law of reflection in vector form: how is - Physics Stack Exchange
WEBMar 8, 2021 · In a reflection, the "normal component (perpendicular to the interface)" of the incident vector is flipped. That's the law of reflection. Note that the parallel component is unchanged by the interface,
Glide Reflections | Algor Cards - Algor Education
WEBGlide reflections are a type of geometric transformation that combines translation with reflection to create symmetrical patterns. This process involves reflecting a figure over a line parallel to the translation vector, then translating it.
