Well, I got it to draw something other than a square shadow. =) Remember before I had said that the shadow appeared as a square-shape just below the shadow caster. It was about the right size and position for the caster, leading me to conclude that the shadow technique was correctly locating the shadow caster, and adjusting its view frustum to fit it prior to rendering the shadow map.
Well, it's doing the same thing now, but now instead of this square 'shadow region' being filled with shadow, it's filled with a pattern of dots. The cool thing is that, among the dots, I do see a silhouette of the shadow caster! However, this silhouette appears to be offset by half the width of the shadow region. Thus, half of it is cut off, and wraps around to the other side! I don't know if you can picture that or not, but it's definitely very weird! But I have learned some interesting things from this! a) It's stable. That is, if I close the program down, and then start it back up again, I get the same exact pattern of dots with the 'offset and wrapped' silhouette. b) The shadow map isn't updating from frame-to-frame anymore. I've tried moving the directional light source's direction around, as well as moved & rotated the shadow caster around. The shadow itself moves as expected, but it always looks the same. So, the position of the shadow changes, but the content of the shadow does not. It's like a projective texture with a static image of a weird shadow on it. I also tried this. Instead of setting the cull mask to 'visibleMask ', I set it to visibleMask | castShadowMask | receiveShadowMask. Now, the shadowing works perfectly! However, it still leaves me with my original problem, which is that if I want to hide an object, I can't just turn its visibility bit off, I have to turn the shadow bits off as well. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=30944#30944 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
