Reflection Formula:
From: | To: |
Reflection calculation is a geometric operation that finds the mirror image of a point across a line or plane. The formula calculates the reflected point given the original point and its projection onto the reflection line/plane.
The calculator uses the reflection formula:
Where:
Explanation: This formula works by doubling the vector from the original point to its projection and subtracting the original point to find the mirror image on the opposite side.
Details: Reflection calculations are essential in computer graphics, physics, engineering, and mathematics for simulating mirror images, light reflections, and symmetric transformations.
Tips: Enter the coordinates of both the projection point and the original point. The calculator will compute the reflected point coordinates using the reflection formula.
Q1: What types of reflections can this calculator handle?
A: This calculator handles point reflections across any line or plane when you provide the projection coordinates.
Q2: How accurate are the results?
A: The results are mathematically precise based on the reflection formula, with rounding to 4 decimal places for clarity.
Q3: Can this be used for 3D reflections?
A: Yes, the same formula applies to 3D space. You would need to provide x, y, and z coordinates for both points.
Q4: What if the projection point is incorrect?
A: The reflection result will be inaccurate if the projection point provided is not the actual orthogonal projection onto the reflection line/plane.
Q5: Are there alternative methods for reflection calculation?
A: Yes, reflections can also be calculated using transformation matrices or vector formulas, but this point-based method is the most straightforward.
