Hi Thomas.

Could it be that you are hitting up against the NVidia driver issue
relating to the handing of uniform arrarys.  The svn/trunk version of
the OSG has a workaround for this issue so would recommend trying
this.

 Hi Guys
 I've been trying to run the osganimationhardware example for osg 3.0.1 on
 windows7 32bit with Geforce GTX 560 and latest drivers 280.26 . In the past
 I have had this running (not on this machine or osg version), I simply
 downloaded the osgData collection with the nathan.osg and skinning.vert
 shader file.
 However now when I'm running it, anything that is skinned does not render. I
 have altered the shader to just use the gl_Vertex position rather then the
 weighted position and then the object renders (so verts are fine). I have
 also used the boneWeight0 uniforms to colour the mesh and they seem to have
 decent values.
 The only thing that doesn't seem to have good values is
 uniform mat4 matrixPalette[MAX_MATRIX];
 When I checked the converted shader the value of MAX_MATRIX seems to be set
 correctly, but if I used the first line of the first matrix as the colour
 value, like
 gl_FrontColor = matrixPalette[0][0];
 It is always black,
 Looking at the uniform attached to the geoms stateset I can see roughly the
 following in the debugger
 _uniformList = [2]((matrixPalette, ({_ptr=0x0d0bfb58 },
 0)),(nbBonesPerVertex, ({_ptr=0x0d0bf3b8 }, 0)))
 _ptr = 0x0d0bfb58 {_parents=[1](0x0d0bfed8 {_parents=[1](0x00df9bf8
 {_name= _dataVariance=DYNAMIC _userDataContainer=0x })
 _modeList=[0]() _attributeList=[1](((PROGRAM, 0), ({_ptr=0x0d0bc9c0 }, 0)))
 ...}) _type=FLOAT_MAT4 _numElements=3 ...}
 osg::MixinVectorfloat =
 {_impl=[48](1.000,0.,0.,0.,0.,1.000,0.,0.,0.,0.,1.000,0.,0.,0.,0.,1.000,0.8939,0.0046100151,0.,0.,-0.0046100151,0.8939,0

 So if the colour is the first vec4 of the matrixPalette uniform it should
 be 1.000,0.,0.,0., but it's just black.
 Can anyone confirm the osganimationhardware example is currently working
 with these assets

Hi Robert,

Yup, that seems to have done the trick. Now onward to no fixed
functionality, yippee (i.e. use osg_vertex etc in shader)

Thanks Again

Hi Again

I've now moved over to IOS and am having the same issue (with the same
version 3.0.1). I'm just now building the latest svn, but you mentioned the
issue was Nvidia related. Do you think the fix might help my IOS build?

Many thanks

Hi Robert

Not sure how relevant to you this is, but as I reported I had the same
uniform mat4 array issue on IOS gles2. I've downloaded and linked to the
latest trunk just now and that has fixed the problem. Was the issue you
mentioned Nvidia specific or OpenGL in general.

I guess it doesn't matter either way, I now have the osganimationhardware
example running on my iPod Touch 4th gen.

Now to try and make it look pretty :)

Cheers
Tom

PS

Only change needed was to attach a fragment shader and change a few variable
names, shaders are attached.

[osg-users] osganimationhardware example osg 3.0.1

2011-09-28 Thread Thomas Hogarth 
Hi Guys

I've been trying to run the osganimationhardware example for osg 3.0.1 on
windows7 32bit with Geforce GTX 560 and latest drivers 280.26 . In the past
I have had this running (not on this machine or osg version), I simply
downloaded the osgData collection with the nathan.osg and skinning.vert
shader file.

However now when I'm running it, anything that is skinned does not render. I
have altered the shader to just use the gl_Vertex position rather then the
weighted position and then the object renders (so verts are fine). I have
also used the boneWeight0 uniforms to colour the mesh and they seem to have
decent values.

The only thing that doesn't seem to have good values is

uniform mat4 matrixPalette[MAX_MATRIX];

When I checked the converted shader the value of MAX_MATRIX seems to be set
correctly, but if I used the first line of the first matrix as the colour
value, like

gl_FrontColor = matrixPalette[0][0];

It is always black,

Looking at the uniform attached to the geoms stateset I can see roughly the
following in the debugger

_uniformList = [2]((matrixPalette, ({_ptr=0x0d0bfb58 },
0)),(nbBonesPerVertex, ({_ptr=0x0d0bf3b8 }, 0)))

_ptr = 0x0d0bfb58 {_parents=[1](0x0d0bfed8 {_parents=[1](0x00df9bf8
{_name= _dataVariance=DYNAMIC _userDataContainer=0x })
_modeList=[0]() _attributeList=[1](((PROGRAM, 0), ({_ptr=0x0d0bc9c0 }, 0)))
...}) _type=FLOAT_MAT4 _numElements=3 ...}

osg::MixinVectorfloat =
{_impl=[48](1.000,0.,0.,0.,0.,1.000,0.,0.,0.,0.,1.000,0.,0.,0.,0.,1.000,0.8939,0.0046100151,0.,0.,-0.0046100151,0.8939,0
