hi,

I try to make a program using GLSL in Performer.
My shader is used to generate a water reflection using
cube texture.

The problem is when I change the camera position in
the viewer using view->setEye(xyz, hpr), the
reflection does not change.

Here my vertex shader:

vNormal = normalize(gl_NormalMatrix * gl_Normal);
vec4 worldPos = gl_ModelViewMatrix * gl_Vertex;
vViewVec = normalize(worldPos.xyz);
gl_Position = gl_ModelViewProjectionMatrix *
gl_Vertex;

and this is my fragment shader:

vec3 reflVec = reflect(vViewVec, vNormal);
vec4 refl = textureCube(envMap, reflVec.xyz);
gl_FragColor = refl;

Is there anyone can help me?

Thanks in advanced
