freak out, the shadow split

wuallen · Post by **wuallen** » Mon Jun 23, 2008 3:18 pm

I don't know how to paste the screen picture. I freak out.

I use addChild() attach a weapon to a dwarf. It looks well, the gun looks right in the hand of dwarf.

I add shadow node to both dwarf and weapon, but the shadow of dwarf and weapon are split far from each other.

How to work out this issue?

Are you viewing the dwarf from various angles so that you can confirm that the weapon actually is in the dwarf's hand?

To post a screen shot upload the screen shot to somewhere like photobucket.com and then you can get a link to post here.

thank you JP, photobucket is a wonderful site.

I upload 3 picture, you can see the big shadow and small shadow split.

There was a patch to fix perspective correctness with stencil shadows: http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=25717 It should look correct after that patch has been applied.

You might also wanna try shadow maps if stencil aint working out for you (Check my sig.)

Hi, BlindSide

I try your code, it works, the shadow of the gun get its right position and the shadow looks more real. But if the shadow gets bigger, the holes gets more. why are there so many holes in shadow, and how to fix this.

hi , I run your test, it also has some hole in shadow. look the picture.

The shape of hole just looks like a house

Yes, that's why I didn't commit the patch, yet, as also posted in the other thread. Unfortuantely, no one yet came up with a working shadow volume algorithm which avoids this stuff...

That's not my code, or my test (It looks like it was a generous submission by "Steel Style").

This is my code.

offtopic:

my eyes got caught up with the quality of the textures.

it looks very much like it passed through ambient occlusion.

or maybe i'm just seeing things.

AFAIK shadow volumes works fine in all cases (after carmack's workaround is applied). Something is inherently wrong with the edge finding algorithm I think?

It is because I get a bad computer,
