Hi everyone !
I'm doing 2D water simulation, and there is a problem in my program.
Just as you see, I render the clip plane below to texture and over it to another texture, eventually to combine 2 texture to water plane.
1. I dont understand why my friends told me I should calculate reflection & refraction vector ? Why I need these vectors ? ( I already finish render the reflection & refraction effect ? ).
2. As you see the picture above, there is a obvious visual error in water plane, when I turn the camera, the goddess body teared ! How does it occurred ? How to fix it ?
