- * objects are interesting, all terrain features except floors (and
- * invisible traps) are interesting, and floors (and invisible traps)
- * are interesting sometimes (depending on various options involving

- *
- * The automatic memorization of all objects and non-floor terrain
- * features as soon as they are displayed allows incredible amounts
- * of optimization in various places, especially "map_info()".
- *
- * Note that the memorization of objects is completely separate from
- * the memorization of terrain features, preventing annoying floor
- * memorization when a detected object is picked up from a dark floor,
- * and object memorization when an object is dropped into a floor grid
- * which is memorized but out-of-sight.
- *
- * This function should be called every time the "memorization" of
- * a grid (or the object in a grid) is called into question, such
- * as when an object is created in a grid, when a terrain feature
- * "changes" from "floor" to "non-floor", when any grid becomes
- * "illuminated" or "viewable", and when a "floor" grid becomes
- * "torch-lit".
- *
- * Note the relatively efficient use of this function by the various
- * "update_view()" and "update_lite()" calls, to allow objects and
- * terrain features to be memorized (and drawn) whenever they become
- * viewable or illuminated in any way, but not when they "maintain"
- * or "lose" their previous viewability or illumination.

- * Some comments on the grid flags. -BEN-
- *
- *
- * One of the major bottlenecks in previous versions of Angband was in
- * the calculation of "line of sight" from the player to various grids,
- * such as monsters. This was such a nasty bottleneck that a lot of
- * silly things were done to reduce the dependancy on "line of sight",
- * for example, you could not "see" any grids in a lit room until you
- * actually entered the room, and there were all kinds of bizarre grid
- * flags to enable this behavior. This is also why the "call light"
- * spells always lit an entire room.
- *
- * The code below provides functions to calculate the "field of view"
- * for the player, which, once calculated, provides extremely fast
- * calculation of "line of sight from the player", and to calculate
- * the "field of torch lite", which, again, once calculated, provides
- * extremely fast calculation of "which grids are lit by the player's
- * lite source". In addition to marking grids as "GRID_VIEW" and/or
- * "GRID_LITE", as appropriate, these functions maintain an array for
- * each of these two flags, each array containing the locations of all
- * of the grids marked with the appropriate flag, which can be used to
- * very quickly scan through all of the grids in a given set.
- *
- * To allow more "semantically valid" field of view semantics, whenever
- * the field of view (or the set of torch lit grids) changes, all of the
- * grids in the field of view (or the set of torch lit grids) are "drawn"
- * so that changes in the world will become apparent as soon as possible.
- * This has been optimized so that only grids which actually "change" are
- * redrawn, using the "temp" array and the "GRID_TEMP" flag to keep track
- * of the grids which are entering or leaving the relevent set of grids.
- *
- * These new methods are so efficient that the old nasty code was removed.
- *
- * Note that there is no reason to "update" the "viewable space" unless
- * the player "moves", or walls/doors are created/destroyed, and there
- * is no reason to "update" the "torch lit grids" unless the field of
- * view changes, or the "light radius" changes. This means that when
- * the player is resting, or digging, or doing anything that does not
- * involve movement or changing the state of the dungeon, there is no
- * need to update the "view" or the "lite" regions, which is nice.
- *
- * Note that the calls to the nasty "los()" function have been reduced
- * to a bare minimum by the use of the new "field of view" calculations.
- *
- * I wouldn't be surprised if slight modifications to the "update_view()"
- * function would allow us to determine "reverse line-of-sight" as well
- * as "normal line-of-sight", which would allow monsters to use a more
- * "correct" calculation to determine if they can "see" the player. For
- * now, monsters simply "cheat" somewhat and assume that if the player
- * has "line of sight" to the monster, then the monster can "pretend"
- * that it has "line of sight" to the player.
- *
- *
- * The "update_lite()" function maintains the "CAVE_LITE" flag for each
- * grid and maintains an array of all "CAVE_LITE" grids.
- *
- * This set of grids is the complete set of all grids which are lit by
- * the players light source, which allows the "player_can_see_bold()"
- * function to work very quickly.
- *
- * Note that every "CAVE_LITE" grid is also a "CAVE_VIEW" grid, and in
- * fact, the player (unless blind) can always "see" all grids which are
- * marked as "CAVE_LITE", unless they are "off screen".
- *
- *
- * The "update_view()" function maintains the "CAVE_VIEW" flag for each
- * grid and maintains an array of all "CAVE_VIEW" grids.
- *
- * This set of grids is the complete set of all grids within line of sight
- * of the player, allowing the "player_has_los_bold()" macro to work very
- * quickly.
- *
- *
- * The current "update_view()" algorithm uses the "CAVE_XTRA" flag as a
- * temporary internal flag to mark those grids which are not only in view,
- * but which are also "easily" in line of sight of the player. This flag
- * is always cleared when we are done.
- *
- *
- * The current "update_lite()" and "update_view()" algorithms use the
- * "CAVE_TEMP" flag, and the array of grids which are marked as "CAVE_TEMP",
- * to keep track of which grids were previously marked as "CAVE_LITE" or
- * "CAVE_VIEW", which allows us to optimize the "screen updates".
- *
- * The "CAVE_TEMP" flag, and the array of "CAVE_TEMP" grids, is also used
- * for various other purposes, such as spreading lite or darkness during
- * "lite_room()" / "unlite_room()", and for calculating monster flow.
- *
- *
- * Any grid can be marked as "CAVE_GLOW" which means that the grid itself is
- * in some way permanently lit. However, for the player to "see" anything
- * in the grid, as determined by "player_can_see()", the player must not be
- * blind, the grid must be marked as "CAVE_VIEW", and, in addition, "wall"
- * grids, even if marked as "perma lit", are only illuminated if they touch
- * a grid which is not a wall and is marked both "CAVE_GLOW" and "CAVE_VIEW".
- *
- *
- * To simplify various things, a grid may be marked as "CAVE_MARK", meaning
- * that even if the player cannot "see" the grid, he "knows" the terrain in
- * that grid. This is used to "remember" walls/doors/stairs/floors when they
- * are "seen" or "detected", and also to "memorize" floors, after "wiz_lite()",
- * or when one of the "memorize floor grids" options induces memorization.
- *
- * Objects are "memorized" in a different way, using a special "marked" flag
- * on the object itself, which is set when an object is observed or detected.
- *
- *
- * A grid may be marked as "CAVE_ROOM" which means that it is part of a "room",
- * and should be illuminated by "lite room" and "darkness" spells.
- *
- *
- * A grid may be marked as "CAVE_ICKY" which means it is part of a "vault",
- * and should be unavailable for "teleportation" destinations.
- *
- *
- * The "view_perma_grids" allows the player to "memorize" every perma-lit grid
- * which is observed, and the "view_torch_grids" allows the player to memorize
- * every torch-lit grid. The player will always memorize important walls,
- * doors, stairs, and other terrain features, as well as any "detected" grids.
- *
- * Note that the new "update_view()" method allows, among other things, a room
- * to be "partially" seen as the player approaches it, with a growing cone of
- * floor appearing as the player gets closer to the door. Also, by not turning
- * on the "memorize perma-lit grids" option, the player will only "see" those
- * floor grids which are actually in line of sight.
- *
- * And my favorite "plus" is that you can now use a special option to draw the
- * "floors" in the "viewable region" brightly (actually, to draw the *other*
- * grids dimly), providing a "pretty" effect as the player runs around, and
- * to efficiently display the "torch lite" in a special color.
- *
- *
- * Some comments on the "update_view()" algorithm...
- *
- * The algorithm is very fast, since it spreads "obvious" grids very quickly,
- * and only has to call "los()" on the borderline cases. The major axes/diags
- * even terminate early when they hit walls. I need to find a quick way
- * to "terminate" the other scans.
- *
- * Note that in the worst case (a big empty area with say 5% scattered walls),
- * each of the 1500 or so nearby grids is checked once, most of them getting
- * an "instant" rating, and only a small portion requiring a call to "los()".
- *
- * The only time that the algorithm appears to be "noticeably" too slow is
- * when running, and this is usually only important in town, since the town
- * provides about the worst scenario possible, with large open regions and
- * a few scattered obstructions. There is a special "efficiency" option to
- * allow the player to reduce his field of view in town, if needed.
- *
- * In the "best" case (say, a normal stretch of corridor), the algorithm
- * makes one check for each viewable grid, and makes no calls to "los()".
- * So running in corridors is very fast, and if a lot of monsters are
- * nearby, it is much faster than the old methods.
- *
- * Note that resting, most normal commands, and several forms of running,
- * plus all commands executed near large groups of monsters, are strictly
- * more efficient with "update_view()" that with the old "compute los() on
- * demand" method, primarily because once the "field of view" has been
- * calculated, it does not have to be recalculated until the player moves
- * (or a wall or door is created or destroyed).
- *
- * Note that we no longer have to do as many "los()" checks, since once the
- * "view" region has been built, very few things cause it to be "changed"
- * (player movement, and the opening/closing of doors, changes in wall status).
- * Note that door/wall changes are only relevant when the door/wall itself is
- * in the "view" region.
- *
- * The algorithm seems to only call "los()" from zero to ten times, usually
- * only when coming down a corridor into a room, or standing in a room, just
- * misaligned with a corridor. So if, say, there are five "nearby" monsters,
- * we will be reducing the calls to "los()".
- *
- * I am thinking in terms of an algorithm that "walks" from the central point
- * out to the maximal "distance", at each point, determining the "view" code
- * (above). For each grid not on a major axis or diagonal, the "view" code
- * depends on the "cave_los_bold()" and "view" of exactly two other grids
- * (the one along the nearest diagonal, and the one next to that one, see
- * "update_view_aux()"...).
- *
- * We "memorize" the viewable space array, so that at the cost of under 3000
- * bytes, we reduce the time taken by "forget_view()" to one assignment for
- * each grid actually in the "viewable space". And for another 3000 bytes,
- * we prevent "erase + redraw" ineffiencies via the "seen" set. These bytes
- * are also used by other routines, thus reducing the cost to almost nothing.
- *
- * A similar thing is done for "forget_lite()" in which case the savings are
- * much less, but save us from doing bizarre maintenance checking.
- *
- * In the worst "normal" case (in the middle of the town), the reachable space
- * actually reaches to more than half of the largest possible "circle" of view,
- * or about 800 grids, and in the worse case (in the middle of a dungeon level
- * where all the walls have been removed), the reachable space actually reaches
- * the theoretical maximum size of just under 1500 grids.
- *
- * Each grid G examines the "state" of two (?) other (adjacent) grids, G1 & G2.
- * If G1 is lite, G is lite. Else if G2 is lite, G is half. Else if G1 and G2
- * are both half, G is half. Else G is dark. It only takes 2 (or 4) bits to
- * "name" a grid, so (for MAX_RAD of 20) we could use 1600 bytes, and scan the
- * entire possible space (including initialization) in one step per grid. If
- * we do the "clearing" as a separate step (and use an array of "view" grids),
- * then the clearing will take as many steps as grids that were viewed, and the
- * algorithm will be able to "stop" scanning at various points.
- * Oh, and outside of the "torch radius", only "lite" grids need to be scanned.
