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.

Maximum number of objects to return.

Radius (in pixels) for picking (default 0).

Picking will happen in a circle centered on the coordinates provided. Radius is the radius of this circle, in pixels.

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

The optional raycaster to use for raycast-based picking. This is mostly useful in the case of point clouds to fine tune the raycaster parameters, depending on the caracteristics of the dataset (i.e size, shape, point density).
