Hi everyone !

I'm practicing "reflection" effect follow the "Raster Tech" way.(http://rastertek.com/dx11tut27.html)

But I see some strange result. I debug the author's source code and my source, both have that odd phenomenon.

Note that marked aera :

What's that ?

When I rotate my camera about X ( Look down at floor ) :

Many odd reflection obj appeared !

I dont know how this phenomenon is generated.

The code is following the link I mentioned above. ( http://rastertek.com/dx11tut27.html )

It looks to me like your reflection texture is wrapping because that same figure in your first image is the same shape as it is at your character's legs. I'm not familiar with the rastertek tutorials, but is there any provisions for clamping the reflection texture coordinates to the [0,1] range?

Thank you , I already fix it, the problem is in the view matrix calculate, I didn't calculate rotation about X and Y, so the result is error. Now I understand the author's way, it makes a virtual camera and do mirror movement.
