Re: [osg-users] iOS: integration with not-OpenGL apps
FYI, it looks like Stephan's FlipsideView example is broken in iOS 6. I get an error when trying to add the view: Code: -[UIView setRootViewController:]: unrecognized selector sent to instance 0xca36f0 2012-10-31 11:53:50.850 viewtest[2745:907] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setRootViewController:]: unrecognized selector sent to instance 0xca36f0' In my project, I ended up creating a custom subclass of UIView, which I use instead of the default one that comes with a UIViewController and added the following method to my custom class: Code: - (void) setRootViewController:(UIViewController*)vc; It's implementation is empty (no op), but it allows the OSG view to be added and everything updates correctly after that. Now my only problem is that my app crashes when the view is Dealloc'd.

Re: [osg-users] [osgPPU] DoF blur issues for antialiased text
Hi all,
I'm still struggling with this and just wanted to add some extra details.
The problem is that the blur around text near the camera is not being combined
with blur further back. It's almost like the blur is being drawn from front to
back while text (rendered as glyphs with alpha channel) are being drawn from
back to front. Is that possible?
I imagine that this would need to be fixed on the shader side. ie, in
depth_of_field_fp.glsl (?):
Code:
void main(void)
{
vec2 inTex = gl_TexCoord[0].st;
// compute distance to the viewer
float a = zFar / ( zFar - zNear );
float b = zFar * zNear / ( zNear - zFar );
float depth = texture2D( texDepthMap, inTex ).x;
float dist = b / ( depth - a );
// get color map and blurred color map values
vec4 colorValue = texture2D (texColorMap, inTex).rgba;
vec4 blurredValue1 = texture2D ( texBlurredColorMap, inTex).rgba;
vec4 blurredValue2 = texture2D ( texStrongBlurredColorMap, inTex).rgba;
// now compute the bluriness value
float blur = clamp(abs(dist - focalLength) / focalRange, 0.0, 1.0);
float factor1 = 1.0;
float factor2 = 0.0;
// compute blend factors
if (blur 0.5)
factor2 = (blur - 0.5) * 2.0;
else
factor1 = blur * 2.0;
// the resulting color value is the combination of blurred and non-blurred
map
vec4 result = mix(colorValue, blurredValue1, factor1);
gl_FragColor = mix(result, blurredValue2, factor2);
}
ie, will gl_FragColor correctly combine previously drawn alpha values?
Any help would be greatly appreciated.
-Mike

[osg-users] osgtext, transparency, and rendering order?
Hi, I have many osgText::text objects flying around a 3D scene (ie, not in a HUD) and transparency is not working correctly. The quads of the text in front entirely occlude the text behind, even though transparency is enabled. Other geometry shows up fine. See the attached image. The white text behind is occluded but the lines of my grid are properly drawn through the transparent regions of the letters. [Image: http://forum.openscenegraph.org/files/spinviewerscreensnapz003_175.png ] If I move the white text in front, both are drawn perfectly. ie, it seems to have something to do with their order of creation (or traversal). For both, I enable blending, depth test, and provide the TRANSPARENT_BIN rendering hint: Code: labelStateSet-setMode( GL_BLEND, osg::StateAttribute::ON ); labelStateSet-setMode( GL_DEPTH_TEST, osg::StateAttribute::ON ); labelStateSet-setRenderingHint(osg::StateSet::TRANSPARENT_BIN); I have played with manually setting rendering bins, which can force a particular text to draw in front of another, but I want all these pieces of text to automatically sort and render correctly without manual input. Any hints?

[osg-users] What can cause glCompileShader FAILED?
Hi all,
Can someone explain what can cause a shader to not compile? I have a two
programs with nearly identical build systems, using the same OSG libraries
(3.1.1) on the same machine. One can compile and run shaders, while the other
produces this:
Code:
Compiling VERTEX source:
1: // microshader - colors a fragment based on its position
2: varying vec4 color;
3: void main(void)
4: {
5: color = gl_Vertex;
6: gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
7: }
VERTEX glCompileShader FAILED
Compiling FRAGMENT source:
1: varying vec4 color;
2: void main(void)
3: {
4: gl_FragColor = clamp( color, 0.0, 1.0 );
5: }
FRAGMENT glCompileShader FAILED
Linking osg::Program id=0 contextID=0
glLinkProgram FAILED
I am invoking it in a standard way like this:
Code:
osg::Geode* geode = new osg::Geode();
geode-addDrawable(new osg::ShapeDrawable(new osg::Box(osg::Vec3(1,1,1), 1)));
root-addChild(geode);
osg::Program * prog = new osg::Program;
prog-addShader ( new osg::Shader(osg::Shader::VERTEX, microshaderVertSource )
);
prog-addShader ( new osg::Shader(osg::Shader::FRAGMENT, microshaderFragSource
) );
geode-getOrCreateStateSet()-setAttributeAndModes( prog,
osg::StateAttribute::ON );
It has to be something in my scene graph. Some state being inherited, or some
setting that I'm unaware of. Any help would be greatly appreciated.
Extra info:
OSX=10.7.3, osgversion=3.1.1, GPU=nvidia GeForce 8600M GT
glVersion=2.1, isGlslSupported=YES, glslLanguageVersion=1.2

Re: [osg-users] What can cause glCompileShader FAILED?
Hi Sebastian, Indeed, I now realize that it is some sort of build setting! To clarify, the program with broken shaders was built with XCode, while the one that works was built with an autotools project. Both link with the same libs and have all the same flags (I think; will verify). Furthermore, I just tried to build the broken program using an autotools system and the exact same code works... so it definitely a setting in my XCode project. I'll poke around to see if I can find the setting, but if anyone knows of an XCode flag that would prevent shaders from working, I'd be grateful to know. -Mike -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=47122#47122 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Problems with DotOsgWrapper in OSG 3.1.1 on OSX 10.7
Okay. I finally have a solution! First thing to note: I didn't have any other gcc compilers other than the llvm gcc 4.2 that came with my XCode app. This is because XCode 4.3.1 comes from the App store and resides in /Applications, and I have NO /Developer folder. So, I used Macports to install a different llvm gcc compiler: Code: sudo port install llvm-gcc42 Then I compiled OSG like this: Code: CC=/opt/local/bin/llvm-gcc CXX=/opt/local/bin/llvm-g++ ccmake ../OpenSceneGraph-3.1.1 (note: you cannot set the CMAKE_OSX_ARCHITECTURE because this compiler doesn't understand -arch flags, so I'm not sure how you would make a universal build this way). I also had to set OSG_WINDOWING_SYSTEM to Cocoa and OPENTHREADS_ATOMIC_USE_MUTEX to ON. Using that build of OSG, my app build, links and runs just fine. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=46959#46959 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Problems with DotOsgWrapper in OSG 3.1.1 on OSX 10.7
So, I spent much of the weekend compiling different versions of OSG (different compilers, universal/non-universal, cmake vs xcode), but no combination has yet fixed the crash. Originally, I used plain cmake to build OSG 2.9.8 libraries and XCode to build my app. This worked for me for the past year, but I was forced to upgrade to OSX 10.7 and XCode 4.3 or some iOS-related work. My app continued to compile (indeed, using the llvm gcc 4.2 compiler) and worked well if linked with those old OSG libraries. But like I said, I wanted to upgrade to OSG 3.x, and stupidly I deleted my old OSG 2.9.8 libraries. Now I can't build ANY form of OSG that will make my app work again. I can't build OSG 2.9.8 anymore, because there are a bunch of deprecated coregraphics calls and no OPENTHREADS_ATOMIC_USE_MUTEX fix. And any OSG 3.X version exhibits the crash (even though the OSG examples work!). I've tried building OSG with both the llvm gcc 4.2 and Apple llvm compiler 3.1, but both crash my app. A few other users have mentioned similar things: http://forum.openscenegraph.org/viewtopic.php?p=42119 http://forum.openscenegraph.org/viewtopic.php?t=8963 Perhaps the same problem (?). Their solution is to NOT using the llvm compiler and use old gcc4.2, but I don't have /usr/bin/gcc-4.2.

[osg-users] Problems with DotOsgWrapper in OSG 3.1.1 on OSX 10.7
Hi, I just upgraded from OSG 2.9.8 to 3.1.1 and my project now crashes when loading .osg models. The error occurs in DeprecatedDotOsgWrapperManager::addDotOsgWrapper (see the backtrace below). The funny thing is that OSG examples work fine. It's just something to do with my project settings. I'm using a custom XCode project, so it's hard to post details here, but can anyone suggest where to look? Am I forgetting to link with something that the deprecated wrappers would need? Everything else works well. In fact, if I enable more verbose notifications, I see that the osgdb_osg plugin loads successfully: Code: FindFileInPath() : USING /usr/local/lib/osgPlugins-3.1.1/osgdb_osg.so Opened DynamicLibrary osgPlugins-3.1.1/osgdb_osg.so It looks like that plugin requests to load the osgdb_deprecated_osg plugin, and then I get the crash immediately after this is printed: Code: FindFileInPath() : USING /usr/local/lib/osgPlugins3.1.1/osgdb_deprecated_osg.so CullSettings::readEnvironmentalVariables() CullSettings::readEnvironmentalVariables() Image plugins (eg, jpeg work fine).

Re: [osg-users] Problems with DotOsgWrapper in OSG 3.1.1 on OSX 10.7
Symbols hidden by default was set to No. Setting it to Yes results in linking errors. The crash occurs in addDotOsgWrapper() when adding the NodeCallback wrapper. Specifically, the line: Code: std::string libraryName = proto-libraryName(); There are several other wrappers that get added beforehand without problem (AlphaFunc, AnimationPath, etc). I don't see any real difference with NodeCallback... In the XCode project settings, I saw a similar option called Inline Methods Hidden which was set to Yes. I tried setting that to No. It still crashes, but now it crashes when adding the wrapper for AnimationPathCallback (which was working before).

Re: [osg-users] [build] OpenGLES2.0 build error
Hi Jordi,
Thanks for the instructions, and sorry for taking so long to respond. I had to
upgrade Xcode to 4.3.1 for a different project and ran into many projects. I'm
wondering if this is responsible for your cmake toolchain not working for me.
XCode 4.3.1 is the .app version, which removes your /Developer folder, which is
a pretty significant change.
I had to change your toolchain file to point to the new SDK location:
Code:
#set(IOS_DEVELOPER_ROOT /Developer/Platforms/${IOS_TARGET}.platform/Developer)
set(IOS_DEVELOPER_ROOT
/Applications/Xcode.app/Contents/Developer/Platforms/${IOS_TARGET}.platform/Developer)
But when I run cmake, I get a compiler error:

I saw in another post (http://forum.openscenegraph.org/viewtopic.php?t=9951)
that you were using clang. What version?
Mike is:
Apple clang version 3.0 (tags/Apple/clang-211.11) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin11.3.0
How far are you from finishing your GLES2 example? I'm eager to try it...
assuming I can get OSG to build properly.
Any ideas are highly appreciated.
Thanks,
Mike

Re: [osg-users] Forked osgIntrospection to cppintrospection
Hi all, I am the main developer for the spinframework, and wanted to chime in to this discussion. First, I've been working with osgIntrospection for some time, and find it a great tool for reflection that really facilitates building editors and networked-based parsers for controlling OSG. And as I understand it, serializers will replace this functionality. I've already played with this a bit, but couldn't find much documentation, and had some problems. I tried Wang Rui's reflection wrappers (see forum topic 5883) ... and I think this will be the way to go once it's stable. Very exciting. In the meantime, there hasn't been a stable tag made for osgIntrospection in the svn. In order to build it, I usually end up deleting a bunch of wrappers that don't compile. Furthermore, we don't need all of the osgWrappers. We just need the core osgIntrospection classes (Type, MethodInfo, etc), as required for reflection or our own classes that we have derived from OSG. * ie, we don't need osgWrappers, just introspection * At some point Robert mentioned that osgIntrospection could become a generic C++ introspection, and this is the inspiration for 'cppintrospection'... something that can be used independently of OSG. I like this idea. Less bloat, and much faster to build for projects like ours. I think the name distinction is necessary, since legacy systems that have versions of OSG 2.9.9 will contain a library called libosgIntrospection, that contains (is linked with) all of the osgWrappers. Anyway, all this is to say that: 1. We can maintain and support a generic, OSG-independent introspection library, called 'cppintrospection'. If someone want to create wrappers for OSG and build a library called something like libOSGWrappers, then these two pieces together could replace osgIntrospection in newer versions. 2. We can help test a new serializer-based reflection library for OSG (minor) we will eventually move to cmake. This could equally replace osgIntrospection. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=37633#37633 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Robert / Wang Rui, I'd be willing to help on this as well. Particularly, I'd like to help get a debian ( ubuntu) package out soon that includes osgIntrospection and genwrapper. Robert, can you add genwrapper to the new repository? Specific things that I am interested in: - ensuring that genwrapper builds properly - ensuring that genwrapper can find OSG's headers and build the wrappers - when the 2.9.9 tag is made for OSG, make a corresponding tag for osgIntrospection (and a tarball) - use the tarball to set up packaging for debian and ubuntu launchpad I'm more familiar with autotools, and would be willing to do all this in that style.

Re: [osg-users] Why is osgIntrospection not in the .deb?
Hi Robert, I use introspection to control OSG from external (networked) processes. Specifically, I have developed an OpenSoundControl protocol allowing users to send arbitrary messages over the network, which get translated into class function calls with appropriate arguments. It's great not having to wrap every single method. I also have a lot of custom classes, build my own wrappers using genwrapper, and use introspection for them as well. I'll look into the serialization support. Hopefully it will be easy to switch over. Otherwise, I guess I'll ship the wrappers myself.

I'd also like to add that osgIntrospection is unlikely to make the cut for OSG-3.0, my current intention is to move it out into its own separate project. The new serialization support is lighter weight and far more maintainable, and with a bit more work looks likely to be able replace much of osgIntrospection's functionality.

Re: [osg-users] Transparent Wall and Grid system Creation
Assuming your cube is an osg shape primitive, I guess you would create
the grid as a texture (with transparency), and add it to the cube. eg,
osg::Texture2D* cubeTexture = new osg::Texture2D();
cubeTexture-setImage(osgDB::readImageFile(somePath));
osg::StateSet *ss = cubeGeode-getOrCreateStateSet();
ss-setMode( GL_BLEND, osg::StateAttribute::ON );
ss-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
ss-setTextureAttributeAndModes(0,cubeTexture,osg::StateAttribute::ON);
But better would be to make a grid from a vertex array. eg, this makes
one side of the cube:
size = 10; // number of grid squares
int numVertices = 8 + (size*8);
osg::Geode gridGeode = new osg::Geode();
osg::Geometry* gridLines = new osg::Geometry();
osg::Vec3 myCoords[numVertices];
for (int i = 0; i = _size; i++)
{
myCoords[i+0+(i*7)] = osg::Vec3(-size, i, 0.0);
myCoords[i+1+(i*7)] = osg::Vec3( size, i, 0.0);
myCoords[i+2+(i*7)] = osg::Vec3(-size, -i, 0.0);
myCoords[i+3+(i*7)] = osg::Vec3( size, -i, 0.0);
myCoords[i+4+(i*7)] = osg::Vec3( i, -size, 0.0);
myCoords[i+5+(i*7)] = osg::Vec3( i, size, 0.0);
myCoords[i+6+(i*7)] = osg::Vec3(-i, -size, 0.0);
myCoords[i+7+(i*7)] = osg::Vec3(-i, size, 0.0);
}
osg::Vec3Array* vertices = new osg::Vec3Array(numVertices,myCoords);
gridLines-setVertexArray(vertices);
gridLines-addPrimitiveSet(new osg::DrawArrays(osg::PrimitiveSet::LINES,
0, numVertices));
Hope that helps.

Hey All,
Right now I am using OSG to code a cube for viewing an IR LED in 3DOF
using 2 wiimotes. The problem I am running into right now is how to turn the
walls of the cube transparent and interlace a grid in the cube to see three
dimensional movement based on the vectors I have calculated to equate one
point in three dimensional space for which it will run around inside of the
cube.
I am calculating the position of the 1 IR LED by triangulating the shortest
vector between the lines of sight and taking its median.
I am very new to OSG and only have a basic C++/C education.
I am sorry if this is too trivial of a question.
...
Thanks all!
Cheers Mates,

[osg-users] ffmpeg plays correct, but slows down after loop
Hi, Has anyone experienced the slowing down of video (approx half speed) after it loops? ie, the movie plays at regular speed the first iteration, but once it loops, the speed is slow. This is an FFMPEG plugin issue. I can reproduce this with the osgmovie example (unmodified) in OSG 2.9.7 The plugin reports the following for the video: Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'OceanBeach1_FullShortShort_H264.mov': Duration: 00:02:24.23, start: 0.00, bitrate: 15663 kb/s Stream #0.0(eng): Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s Stream #0.1(eng): Video: h264, yuv420p, 1024x1024, 30 tbr, 600 tbn, 1200 tbc One last question: What is the optimal format for ffmpeg + osg?

Re: [osg-users] multiple render targets / cameras
It's probably osgViewer::CompositeViewer that you want, not osgViewer::Viewer. There's an example in the source. That way you create two different osgViewer::Views, and each can have it's own manipulator. The control is up to you, but if you want automated rotations and panning, I usually use NodeTrackerManipulator instead of TrackBallManipulator. I just create a PositionAttitudeTransform somewhere in my scene that represents the camera position, and animate it in a callback like Jason suggests. -Mike Jason Daly wrote: Bob Youmans wrote: My questions are currently: 1.What’s the best way to connect the two cameras so they’re the same position orientation, only rendering to different targets (e.g., update the matrix of one with the other using an update traversal, put both under a transform node in a tree, etc.)? This sounds like a plain old osgViewer::Viewer with a slave camera is the way to go. You control the viewpoint with the master camera, and both cameras render wherever you need them. I think the osgsidebyside example may give you an idea how to set this up (it's not exactly what you're looking for, but a lot of the code is relevant). osgprerender might also be relevant. 2. What’s the best way to programmatically (vs TrackBallManipulator default) control the camera, and/or switch between these methods? The most straightforward way to do this is with an UpdateCallback.

[osg-users] osgviewerWX on OSX
Hi,
I have a WX app with an OpenGL viewer that based on the osgviewerWX
example in the OSG release. I won't include the code, since it's a bit
complicated, but I'm wondering if anyone would know why the viewer
window is empty (I just see the clearcolor of the camera) on OSX while
it works perfectly in Linux?
If it helps, I get the following compilation warnings:
/opt/local/include/wx-2.8/wx/mac/carbon/glcanvas.h:49: warning:
‘AGLDrawable’ is deprecated (declared at
/System/Library/Frameworks/AGL.framework/Headers/agl.h:61)
/opt/local/include/wx-2.8/wx/mac/carbon/glcanvas.h:53: warning:
‘AGLDrawable’ is deprecated (declared at
/System/Library/Frameworks/AGL.framework/Headers/agl.h:61)
Also, once I add something to my scene, I get the following error
printed every frame:
CullVisitor::apply(Geode) detected NaN,
depth=nan, center=(0 0 0),
matrix={
nan nan nan nan
nan nan nan nan
nan nan nan nan
nan nan nan nan
}
Any idea where I should look?
The code is very similar to osgviewerWX, with one notable exception: the
frame that holds the OSGCanvas is not shown by default. It is created
while hidden, and can be opened (using Show()) by the user when he/she
desires. It's not a problem in Linux though...
Any feedback would be greatly appreciated.
Thanks,
Mike

Re: [osg-users] Creating custom wrappers for osgIntrospection
Actually, nevermind about genwrapper. I've managed to use the latest svn version to create custom wrappers for my classes (yay). Now what I would like to do, is to build a scene-graph editor GUI to edit my class properties. Details: * I particularly like wxWidgets and gtk. * The editor doesn't need to render the scene in the same process (for now). All I need is a tree-view of the scene, with panels that open when a particular node is clicked. * I would like to be able to choose what types of nodes appear in the tree-view. Only my custom nodes and a small subset of osg nodes (eg, osg::Group, osg::PositionAttitudeTransform, and a couple others) should appear. * Must rely on osgIntrospection and osgWrappers generated by genwrapper... I was excited about osgedit, until I realized that it uses some other (custom) reflection mechanism. Does anyone have some simple examples? Are there any libraries that use osgWrappers osgIntrospection to provide a GUI?

[osg-users] compile subset of OSG without openGL?
Hi all, I have an simple OSG application that I'm trying to port to a small mobile device (Gumstix), and I'm trying to cross-compile a small subset of the OSG library. I don't have OpenGL or X11 available on the device, but I don't need that, because I'm only using OSG for basic scene graph organization and 3D geometry. *** I don't need to create windows or render anything *** So my questions are: - First, is this possible? - Has anyone built a subset of OSG and could provide me with a template for doing so? - Does anyone have a basic makefile (not cmake) that I can modify to generate a subset of libosg that doesn't link with libGL, libX11, etc. - I don't really understand the cmake system, so can anyone point me to the place where libosg is built? ... or provide me with some basic info about changing compilers and preventing cmake from looking in the regular locations (eg, /usr/include, /usr/lib, etc)?

Re: [osg-users] Viewer Windowing Problems
I can confirm similar (but slightly different) behaviour. - My osgviewer cannot leave fullscreen at all. I see a window flash for a brief moment, but then fullscreen returns. This seems to happen only the first time I press the 'f' key. Nothing happens on any subsequent presses. (ubuntu 7.10, nvidia, compiz disabled, OSG 2.2) - In some cases (eg, when compiz is enabled), leaving fullscreen mode just makes the viewport smaller, but doesn't create a window, and doesn't destroy the old fullscreen viewport (ie, I still see the last update of my scene in fullscreen, with a superimposed smaller viewport that continues to update). -Mike Robert Osfield wrote: On 10/23/07, Robert Osfield [EMAIL PROTECTED] wrote: On 10/23/07, Jeremy L.

[osg-users] seamless perspectives with multiple (rotated/translated) osgViewer slaves
Hi All, I'm struggling to understand how to properly offset a slave in osgViewer, and still have the perspectives line up for tiled and CAVE-like displays. For example, I have one OSG window to render the left corner of a CAVE. The window has 2 cameras: The left camera has a viewport that covers the left half of the window and is rotated -90 degrees. The center camera has a viewport that covers the right half of the window and is not rotated. left camera: viewer.addSlave(camera.get(), pMatrix, osg::Matrix::rotate(osg::inDegrees(-90), 0,1,0)); center camera: viewer.addSlave(camera.get(), pMatrix, osg::Matrix::()); How do I compute the correct pMatrix to ensure that the frustums line up in a seamless fashion (ie, objects do not disappear or become duplicated)? Note that through trial and error, I have found a pMatrix that works: pMatrix = osg::Matrixd::scale( viewportWidthRatio * traits-width / 3150, 1, 1 ); But I don't understand why I have to scale by 3150? It seems that it's related to the size of the viewport... so in my case my full window width is 2048, so I have: 0.5 * 2048 / 3150 = 0.325. Why this value? Also, in case it's important, the master camera is attached to a NodeTrackerManipulator that I define like this: nodeTracker = new osgGA::NodeTrackerManipulator(); nodeTracker-setTrackerMode( osgGA::NodeTrackerManipulator::NODE_CENTER_AND_ROTATION ); nodeTracker-setRotationMode( osgGA::NodeTrackerManipulator::ELEVATION_AZIM ); nodeTracker-setHomePosition(osg::Vec3d(0,0,0), osg::Vec3d(0,1,0), osg::Vec3d(0,0,1)); The other question I have: what if the left view is not rotated, but planar to the center? ie, the eye looks directly forward through the center camera, and the left camera shows a translated and thus distorted view? What is the proper way to set my pMatrix for that? Obviously it's not just a scaling operation and requires skewing. Any insight would be greatly appreciated!
