Fix lighting shader #60

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
A recent change has caused the phong_lighting shader to incorrectly shade
surfaces. To try this, run any of the lighting demos, notice how the light
becomes brighter as the camera approaches the surface.

This issue has been fixed. The problem was that the phong_lighting.vert shader 
was
not writing to the varying variable wvPosition which is used by the fragment 
shader.
Adding the line:
wvPosition = (g_WorldViewMatrix * pos).xyz;

to the vertex shader fixed it.
