The next part of the height map terrain series adds simple water and water reflections.  For the water, the tutorial uses a flat textured quad and scrolls the UV for water movement.  For the reflection portion, glClipPlane() is used and the scene is rendered upside down to produce the reflected effect on the water surface.

Functions Used:  glBegin(), glEnd(), glVertex3i(), fopen(), fread(), fclose(), glBindTexture(), glMultiTexCoord2fARB(), glTexEnvi(), glClipPlane(), glBlendFunc(), glCullFace(), glPushMarix(), glPopMatrix(), gluBuild2DMipmaps(), glMatrixMode(), glActiveTextureARB(), glScalef(), glLoadIdentity(), glFogi(), glFogCoordfEXT()
