Reflection and line of reflection math
Web21. jún 2015 · If you can calculate the normal of the line (blue arrow), then you can use a dot product to do the reflection: Calculating the normal for the line is done like this: local normalY = line.x2 - line.x1 local normalX = line.y1 - line.y2 local normalLength = math.sqrt (normalX * normalX + normalY * normalY) normalX = normalX / normalLength normalY ... WebA reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to reflect the other figure, and then every point in a figure is equidistant from each corresponding point in another figure. The reflected image should have the same shape and size, but the image faces in the ...
