Well, TNG 3D is importing the four bottles—but their transforms seem to be all the identity, and the file scale looks way off…

I’m attaching a screenshot from the TNG 3D layout application (not freely available, sorry).

HTH,

The vertex positions seem to be scaled way up.

GetControlPointAt for the first vert is:

59999998658.895493
0.00000000000000000
42500000447.034836

Yes its the individual transform setting that eludes me.

I can set the nodes transform and thus its position location but this does not
necessarily get read properly when it gets reloaded.

FBX has deprecated some functions related to the transforms but even
using the new code its only the KFBXNODE transform that will
keep the data for the node, and it is this data I THINK that must be used
to view its transform, not the transform of the instanced mesh.

Thus your display could be right or wrong depending upon whose transform you use when
you load the file.  Do you load the node’s transform for the mesh or the mesh’s transform for
the nodes????

Dunno however if this is correct as it is and I have to interpret this
transform or if there is yet another one.

Yes I use those functions.  The offset data per node is there, but perhaps as I dont set the scale it scales all of my geometry up by some default level.  Thus it appears as there is only 1 bottle.  I will adjust the scale and retest.  Thanks.

I think I have sorted my scale.  My model loads correctly in deepview, and I will now start writing my own reader to process instancing.  However your viewer didnt seem to load the instances.  Here is a new instanced fbx file - this time with four cans.  Its in ascii mode.

And here it is again zipped ....

TNG 3D is loading the can instances—see attachment.
This time the scale is really, really small… so are the transforms.

My version of your software is a few weeks old.  I will download a newer one and try. Thanks.

ok.  In doesnt matter now I have worked out why it was not right.  I will move onto writing the instance importer. Thanks for the data validation.

I corrected the cubecreator sample produced by the fbx team so it supports instancing, and can display the results in DeepView but it still wont display in Tngviewer.  Have you tried displaying a model with instances in your tngviewer??  Not the other app you show.

Here is he corrected code:

KFbxNode * gFirstNode = NULL;
// create a new cube
void CreateCubeDetailed( char* pCubeName,
double pX,
double pY,
double pZ,
int pRotateAxe,
bool pWithMaterial,
bool pWithTexture,
bool pAnimate
)
{
KFbxNode* lCube = NULL;

if( gCubeNumber < 2 )
{
lCube = CreateCubeMesh(gScene, pCubeName);
gFirstNode = lCube;
}
else if( NULL != gFirstNode )
{
// create a KFbxNode
lCube = KFbxNode::Create(gScene,pCubeName);

// set the node attribute
lCube->SetNodeAttribute(gFirstNode->GetMesh());

// set the shading mode to view texture
lCube->SetShadingMode(KFbxNode::eTEXTURE_SHADING);

// rescale the cube
lCube->LclScaling.Set(KFbxVector4(0.3, 0.3, 0.3));
}
