[osg-users] [osgOcean] Iam in a puzzle about the realization of osgOcean's 'Glare effect'
Hi,
I saw the code in 'OceanScen.cpp', that 5 cameras in
'osgOcean::OceanScen::_glarePasses' were used to render the glare effect.
But I saw the realization code in water.frag is just as bellow:
if(osgOcean_EnableGlare)
{
float lum = luminance(lumColor);
gl_FragData[1] = vec4(lum);
}
And it looks like that the cameras in 'osgOcean::OceanScen::_glarePasses' were
not been used anywhere. Will tell me why?
Thank you!
Cheers,
Tian

This isn't helped by the fact that I keep forgetting to put the test code on the svn so other people can't see the approach.

Could the ocean surface geometry be defined at initialization at the scene graph level for each tile/frame rather than being redefined every 50ms as it doing now.

Funny :) Kim Bale wrote: Kim, *ahem* Replying to myself there for some reason.. K. 2010/1/6 Kim Bale () Kim, This is to some extent what already happens with the mipmapping LOD that osgOcean currently uses. The problem is that the multi-res surface is dependant on the position of the camera and not on local features. The code to recompute the surface primitives is already pretty complicated, to do it based on both camera position and local features would be a nightmare (if at all possible). One way to address this would be to increase the resolution of the highest level of detail and only apply the iwave algorithm to tiles in close proximity to the camera.

Unfortunately I won't get round to fixing this immediately. However, if you want to use the version in the trunk you can probably get round it by replacing the uniform booleans one by one with hard coded values in the water shader for the options you want to enable until it stop complaining.

Re: [osg-users] [osgOcean] osgOcean also rendering with osgParticle?
Hi Kim: It is really my honor to test the new Version. The follow links are my test effect on my own computer: 1.We can see that: the sharp white around the boat is still there, although the around water looks transparent. http://storage.openlab.net.cn/forums/2009-11-24/1981569/boat.JPG 2. When I look up to the boat under the ocean, the boat's color seems abnormal( purple ). http://storage.openlab.net.cn/forums/2009-11-24/1981569/down_up.JPG 3.The foams around the island gone, and the water is just transparent around the shore. http://storage.openlab.net.cn/forums/2009-11-24/1981569/foam.JPG I will test the particle effect tomorrow morning on my work computer.

Color buffer writes are now done to gl_FragData[0] and luminance/depth writes to gl_FragData[1]. You can see these changes in the water, terrain and default shaders. Let me know how you get on.

It's possible that one side of the model is being culled in the reflection and you're seeing the inside of the model.

You're more than welcome to have a play with the effect and see if you can do anything with it. From what I understand what you'd need to do is add a sort of sloped geometry which tracks you your boat, that would get picked up in the depth buffer and the same foam texture used on the wave crests is applied to it. It's been checked into the trunk, but like I say it needs a little work. There was a discussion about it here: http://thread.gmane.org/gmane.comp.graphics.openscenegraph.cvs/6252 Cheers. Kim. 2009/11/18 Erik Johnson : Hi, I thought this would have come up before, but does anyone have suggestions how to render a boat's wake? Using osgParticle provides an ok solution, but falls apart rapidly if the ocean waves are too large (the particles go underwater). Would be cool to leverage the same texturing effects as the wave crest foam stuff - just not sure how. :) Thanks for any suggestions, Erik -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=19849#19849 ___ osg-users mailing list http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Post generated by Mail2Forum -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=20042#20042 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I have downloaded the newest version through SVN, and also compiled the code
successfully.
When I turn on the oceanExample's testCollision, I found that the

In the example, you did not add any shader to the model. Does this mean
that: a default shader was added to the model? But why the model looks just
white?
Will you please give us a example about how to add a model to the oceanScene
to keep what they are?

Hi MT,
For the reasons I just gave, you can't add objects to the scene and

Reflections/refractions etc will continue to work since they act on
the ocean surface and not the model. However, other such as glare,
depth of field, light scattering, fogging etc will not as they act on
the models themselves.
However, it is pretty straight forward to duplicate a subset of fixed

default shader and mix them in with the result of your shader.

Hi Jan, Tian,
osgOcean uses shaders for pretty much every effect in the scene -

effects. This is particularly necessary if the fullscreen effects are

In order to address this issue, OceanScene will apply a default shader

illustrates how to use the uniforms supplied by osgocean (prefixed
osgOcean_* ) in conjunction with your own shader. Since I could not

it only offers a very basic implementation (1 texture unit, limited
phong lighting etc) and should be seen as a shader to customise and
build on yourself.
You can override the default shader either by attaching a new program
to the object you wish to use in the scene or by using this function
in OceanScene:
/** Override the default scene shader for custom shaders.

The terrain is an external model that has a custom shader applied to

Hello Tian,
Was it those that you deleted? Yes, I just delet thems, because I found
that these two inline functions had not been used in anywhere. And now
my project just goes right, the same with the oceanExample.
Sorry I didn't pick up on this thread... I'm pretty darn busy so I just
glance over threads that I don't immediately have an answer for, but
looking at the OceanScene header in the osgOcean-1.0 tag, lines 213 and
223, it was immediately obvious what the problem was. You do not need to
delete them. Just rename the variables called near and far to
something else, like this for example:
/** Set near DOF blur distance.
* Updates the uniform is DOF state is valid.
*/
inline void setDOFNear( float zNear ) {
_dofNear = zNear;
if( _dofStateSet.valid() )
_dofStateSet-getUniform(osgOcean_DOF_Near)-set(_dofNear);
}
/** Set far DOF blur distance
* Updates the uniform is DOF state is valid.
*/
inline void setDOFFar(float zFar ) {
_dofFar = zFar;
if( _dofStateSet.valid() )
_dofStateSet-getUniform(osgOcean_DOF_Far)-set(_dofNear);
}
Just for general reference, the problem was that on Windows compilers
(and previously DOS), near and far were once keywords used to refer
to memory inside the first 64k page, and outside, respectively (back
when you needed to address them differently, which is a long time ago).
Nowadays it's pretty obsolete, but some compilers on PC still carry that
legacy. And I get bitten by it every time I do OpenGL or raytracing code
that needs to have a frustum, with near and far planes :-)
And it doesn't matter that these methods are not used in osgOcean or the
oceanExample themselves, they're still useful methods to have in order
to be able to tweak osgOcean's rendering.
Sorry , I did not know the meaning of the trunk update clearly.
Kim meant checking out from
http://osgocean.googlecode.com/svn/trunk/
instead of
http://osgocean.googlecode.com/svn/tags/osgOcean-1.0/
The 1.0 tag is pretty old now, people should not check out using it
anymore... Kim, is it possible to make changes on the googlecode site so
that it doesn't show up by default when people click on the source
tab? The default checkout should be from the trunk now. And the trunk
has the above fix already, btw.
Hope this helps,
J-S

Re: [osg-users] [osgOcean] 3D model material display error!
Hi Kim:
Thank you again :)
I will try your advise.
Regards,
MT

Hi MT,
For the reasons I just gave, you can't add objects to the scene and
have the full compliment of effects without either using the default
shader or using your own shader implementation.
Reflections/refractions etc will continue to work since they act on
the ocean surface and not the model. However, other such as glare,
depth of field, light scattering, fogging etc will not as they act on
the models themselves.
However, it is pretty straight forward to duplicate a subset of fixed
pipeline functionality within a shader and then add the relevant
osgOcean shader effects to it, you can just copy functions from the
default shader and mix them in with the result of your shader.

Hi Jan,Kim:
Thank you a lot.
Kim, does it means that: I can never keep the models looks like what
they are before? And I have to program shaders for every loaded models, in
order to have reflect or other effects?
I want to know that: is there a simple way to make the models just look
like what they are?
Kim Bale wrote:
Hi Jan, Tian,
osgOcean uses shaders for pretty much every effect in the scene -
fogging, depth of field, glare, lighting etc. If objects that are
added to the scene are to look consistent with the ocean effects they
will require a shader to be applied that takes into account these
effects. This is particularly necessary if the fullscreen effects are
used as they require the alpha component of the frame buffer to work.
In order to address this issue, OceanScene will apply a default shader
to objects added as children (default_scene.frag vert) which
illustrates how to use the uniforms supplied by osgocean (prefixed
osgOcean_* ) in conjunction with your own shader. Since I could not
anticipate the many wierd and wonderful ways that shaders can be used
it only offers a very basic implementation (1 texture unit, limited
phong lighting etc) and should be seen as a shader to customise and
build on yourself.
You can override the default shader either by attaching a new program
to the object you wish to use in the scene or by using this function
in OceanScene:
/** Override the default scene shader for custom shaders.
* If custom shaders are required for individual nodes add them
before adding to the OceanScene.
* Dirties state.
*/
void setDefaultSceneShader( osg::Program* program )
{
_defaultSceneShader = program;
_isDirty = true;
}
Alternatively you can turn the default shader off completely with
setter in OceanScene.
Regards,
Kim.

Hi,
When I load a model into the osgOcean scene, the model looks white
all
over, without any material. Anybody knows why?
Yes, I have seen the same thing. I believe that the shaders applied by
osgOcean are responsible and are not passing the the vertex colors
along.
I have yet to check the shader code, though.
Regards,
Jan

Re: [osg-users] [osgOcean] Error used osgOcean1.0 in MFC vc2005sp1
Thank you， Kim! THX a lot! Was it those that you deleted? Yes, I just delet thems, because I found that these two inline functions had not been used in anywhere. And now my project just goes right, the same with the oceanExample. Sorry , I did not know the meaning of the trunk update clearly. And I just put the ocean code in MFC+OSG project's function:InitSceanGraph(). Cheers, mt Kim Bale wrote: Hi MT, I found that: the two lines of error code in oceanscean.h had not been used in anywhere, so I just delete them. If the problem relates to lines 213 and 223 in the OceanScene header then those member variables are used to set and store the depth of field parameters.. Was it those that you deleted? If the trunk update didn't solve it I'd be keen to find out what the real cause is.
