For each valid (e.g., visible) location on the surface of a transparent or translucent object, one or more rays are traced through such objects and the resulting lighting is computed in an order-independent fashion. The results are stored in a texture, which is then applied during the final lighting stage.

A digital medium environment includes an action processing application that performs actions including personalized recommendation. A learning algorithm operates on a sample-by-sample basis (e.g., each instance a user visits a web page) and recommends an optimistic action, such as an action found by maximizing an expected reward, or a base action, such as an action from a baseline policy with known expected reward, subject to a safety constraint. The safety constraint requires that the expected performance of playing optimistic actions is at least as good as a predetermined percentage of the known performance of playing base actions. Thus, the learning algorithm is conservative during exploratory early stages of learning, and does not play unsafe actions.

Potential trap peaks are identified within the plurality of grid cells. An invasion percolation (IP) process is performed until the HC stops migrating upon arrival to the plurality of trap peaks. A determination is made as to whether the grid cells containing HC contains an excess volume of HC. An accumulation process is performed to model the filling of the HC at a trap associated with the identified potential trap peaks. The trap boundary cell list is updated in parallel together with an HC potential value. Trap filling terminates when excess HC is depleted or a spill point is reached.

A novel passive flow restrictor attached outside the tubing in an oil well and positioned below casing perforations, causing fluid flow from an oil reservoir formation to at least partially flow through a narrow annular space between the flow restrictor and the casing before entering the tubing. The flow resistance is thereby defined in part by the length of the annular space, which is easily adjusted by lowering or raising the tubing within the casing. The flow restrictor and methods of using thereof are especially advantageous for maximizing oil production in thin oil rim gas reservoir as well as with other oil wells with high Gas-to-Oil Ratio.
