Interface PickOptions

Filter on the picked results

If disabled, picking will using CPU raycasting when possible (rather than GPU picking). Main differences between CPU raycasting and GPU picking:

• CPU raycasting is generally much faster to execute and does not require blocking the thread to wait for the GPU queue to complete.

Disadvantages:

• CPU raycasting might give less accurate results in some specific cases,
• CPU raycasting might not return complete information, only the picked point coordinates.
• CPU raycasting does not ignore transparent pixels, whereas GPU picking does. It might be a disadvantage or advantage depending on the use case.

This is honored by all native Giro3D picking methods, but may not be honored by customized picking methods.
