(1)Why the light in pipeline "forward" is much darker than the one in "HDR".
(2)When i tried to draw the basic geometric shapes(like rectangles, circles) after the code "h3dFinalizeFrame()", the effect in pipeline "forward" is fine, but for "HDR", if i adjust the camera, some part will disappear.Why did this happen?

How to solve these? Thanks!

Looks like some depth buffer / testing issues.

Could you give me some detail explanation? I'm freshmen of this branch, or could you recommend some materials?

Thanks.
