Struct re_renderer::draw_phases::picking_layer::PickingResult

pub struct PickingResult<T: 'static + Send + Sync> {
    pub user_data: T,

    pub picking_id_data: Vec<PickingLayerId>,
    pub picking_depth_data: Vec<f32>,
    world_from_cropped_projection: Mat4,
}

GPU retrieved & processed picking data result.

Fields

user_data: T

User data supplied on picking request.

rect: RectInt

Picking rect supplied on picking request. Describes the area of the picking layer that was read back.

picking_id_data: Vec<PickingLayerId>

Picking id data for the requested rectangle.

GPU internal row padding has already been removed from this buffer. Pixel data is stored in the normal fashion - row wise, left to right, top to bottom.

picking_depth_data: Vec<f32>

Picking depth data for the requested rectangle.

Use PickingResult::picked_world_position for easy interpretation of the data.

GPU internal row padding has already been removed from this buffer. Pixel data is stored in the normal fashion - row wise, left to right, top to bottom.

world_from_cropped_projection: Mat4

Transforms a NDC position on the picking rect to a world position.

Implementations

impl<T: 'static + Send + Sync> PickingResult<T>

pub fn picked_world_position(&self, pos_on_picking_rect: UVec2) -> Vec3

Returns the picked world position.

Panics if the position is outside of the picking rect.

Keep in mind that the picked position may be (negative) infinity if nothing was picked.

pub fn picked_id(&self, pos_on_picking_rect: UVec2) -> PickingLayerId

Returns the picked picking id.

Panics if the position is outside of the picking rect.
