Starting from an analyst.IField object you can use scripting to evaluate the field at a given location using the Sample function:
sample = Field_1.Sample((-.02, 0.005, 0.0025))
print(sample)
The function takes 1 argument:
Point - Tuple of doubles indicating the location to sample at in meters.
The function returns a tuple of doubles formatted as:
[Field at Point]
Where the content of [Field at Point] depends on the various factors including:
Dimension of the field (FDD_SCALAR, FDD_VECTOR. This can be checked by calling IField::GetDataDimension(). The scalar case will return 1 value per point and the vector case will return 3 values per point.
Data type of the field (FDT_FLOAT, FDT_FLOAT_COMPLEX, FDT_DOUBLE, FDT_DOUBLE_COMPLEX). This can be checked by calling IField::GetDataType(). The real cases will return 1 value per component and the complex cases will return 2 values per component.
Taking this into consideration, sampling a complex vector field will a tuple of 6 values (x.real, x.imag, y.real, y.imag, z.real, z.imag). Sampling a real vector field will return a tuple of 3 (x, y, z).
