Iterating over voxels

[Macha]

Does anybody have a short example of inlinecpp that iterates over an existing volume?

 

Thanks.

Hey Marc, I don't have a current inlinecpp example for that. But the docs have a good section on iterating through volumes and their values.

 

http://www.sidefx.com/docs/hdk13.0/_h_d_k__volumes.html

 

This should give you an idea on the functions needed to do that. I'll look at seeing what could be done with the inlinecpp.

Thanks Rick, I've been looking at those before but can't get it to work. I can't even find the right includes for the UT_VoxelArrayIterator, and I have tried a lot of them.

 

It makes me think it is an inlinecpp specific problem. That's why I am asking for a short example.

[Ratman]

I believe it should be GU/GU_Detail.h and GU/GU_PrimVolume.h on the HDK side of things.

Definitely gonna have to look into it on the inlinecpp side of things.

[Macha]

No, none of these includes are sufficient. From the examples it looks like they should, but it doesn't work, at least with the inlinecpp stuff.

Looks to me as if all handles related to voxel arrays in inlinecpp are spewing out errors related to boost?

If i may ask a question kind of related to this topic : can anyone tell me how to properly use a UT_VoxelArrayIteratorV4 to iterate over a SIM_VectorField.

For now what i'm doing is :

UT_VoxelArrayIteratorF myvectorFieldIterator[3];
for (int i = 0; i < 3; i++)
{
	myvectorFieldIterator[i].setArray(myvectorField->getField(i)->fieldNC());
	myvectorFieldIterator[i].rewind();
}

and what i would like to do is :

UT_VoxelArrayIteratorV4 myvectorFieldIterator;
myvectorFieldIterator.setArray(myvectorField->getField()->fieldNC());

But it seems i can't set a UT_VoxelArrayV4 to the UT_VoxelArrayIteratorV4 with the setArray() method =/
