hi all,
I have implemented the intersection effect between a block mesh and a geometry
(kind of like capping effect)by multi-pass render as used in other
osgFx::effect.
Now I have lots of blocks with different depth, I add each block and the same
geometry into an effect node, as shown below:
rootnode
--effect node1
--block mesh1 + geomBox
--effect node2
--blcok mesh2 + geomBox
...
--effct node18
--block mesh18 + geomBox
all effect nodes could be individual rendered in right way, but the depth of
different nodes are totally messed.
Regardless of their actual depth values, the subsequent nodes always overwrite
the previous nodes.
I think it is because I forced to write the block depth into the depth buffer
during the effect process.
So I want to know how can I render each effect into different depth buffer but
combine those depth buffer at rootnode to decide the color buffer?
...
Thank you!
Cheers,
neman
