Accessing a voxel of SIM_ScalarField by index

[Hojun Yoon]

Hello, I'm trying to write a microsolver that changes the scalarfield's voxel value according to the points position of the given geometry. So, I'd like to know how to access the voxel data of SIM_ScalarField by index vector without iterating entire field. For example, changing the voxel value in [2, 10, 6] to 1.

Thank you.

You probably need to get access to underlying voxel array via raw field. 

//  SIM_ScalarField *source....
SIM_RawField  *raw_field = source->getField(); 
UT_VoxelArray *array = raw_field->fieldNC(); 
array->setValue(vx, vy, vz, 1.0f);
