Hi, 

 

i'm trying to implement directional shadow in cube reflection map.  I'm trying to avoid the case where i have to re-render reflected objects into separate shadow map.  Here is what i'm thinking ...

 

- render cube reflectionmap along with cube depth map

- for each pixel in reflectionmap, (all cube texture) cast a ray to the sun, and use cube depth map to check if ray is obstructed by object

- if it's obstructed, then shade a pixel.

 

i'm not quite sure about step 2, is it possible to use the ray vector as reflection vector into cubemap ref. texture?
