thanks ikework, <br />
but i did it in much easier way by finding the reflection vector with the constraint that the reflection, incident and normal should be in same plane, which game the ability to directly calculate the reflection vector without converting

Hello,<br />
I've beam of light, which has direction in spherical coordinates in right-handed system of coordinates. <br />
angle theta is the angle between the beam vector and axis y,<br />
angle phi is the angle in x-z plane.<br />
<br />
i need &nbsp;the vector to be reflected when it hits a surface, which has normal N.<br />
<br />
how can I calculate the new theta and phi angles, of the reflected vector?<br />

Hello,
I've beam of light, which has direction in spherical coordinates in right-handed system of coordinates. 
angle theta is the angle between the beam vector and axis y,
angle phi is the angle in x-z plane.

i need  the vector to be reflected when it hits a surface, which has normal N.

how can I calculate the new theta and phi angles, of the reflected vector?


Reflection in Spherical Coordinates

Game programming is the software development of video games. Game programming requires substantial skill in software engineering as well as specialization in simulation, computer graphics, artificial intelligence, physics, audio programming, and input. Like other software, game development programs are generated from source code to the actual program by a compiler. Source code can be developed with almost any text editor, but most professional game programmers use a full integrated development environment (IDE).
