Previously we had a single culling frustum based on the main camera, and
any object outside the frustum would never get rendered, even if it
should actually contribute to shadows or reflections/refractions. This
caused ugly pop-in effects in the shadows and reflections while
scrolling.
Extend the renderer to support multiple cull groups, each with a
separate frustum and with separate lists of submitted objects, so that
shadows and reflections will render the correctly culled sets of
objects.
Update the shadow map generation to compute the (hopefully) correct
bounds and matrices for this new scheme.
Include terrain patches in the shadow bounds, so hills can cast shadows
correctly.
Remove the code that tried to render objects slightly outside the camera
frustum in order to reduce the pop-in effect, since that was a
workaround for the lack of a proper fix.
Remove the model/patch filtering code, which was used to cull objects
that were in the normal camera frustum but should be excluded from
reflections/refractions, since that's redundant now too.
Inline DistanceToPlane to save a few hundred usecs per frame inside
CCmpUnitRenderer::RenderSubmit.
Fixes#504, #579.
This was SVN commit r15445.
Allow components to individually subscribe/unsubscribe to messages,
instead of statically subscribing the entire component type. Use this
for most Interpolate/RenderSubmit messages, to avoid the performance
cost of passing those messages to a large number of components that will
just ignore them anyway.
On Azure Coast this reduces total time per frame by about 30% on a
CPU-bound system.
This was SVN commit r15400.
Adds converted Relax NG XML grammars for each (Note: don't edit these
directly, modify the compact syntax .rnc files instead, then use a
conversion tool http://relaxng.org/#conversion to generate the .rng
files).
Adds Perl script to validate the XML files using the new grammars
This was SVN commit r15377.
Once 'delete' is called on an object, that object no longer exists, and
accessing its member variables is undefined behaviour. GCC 4.9's
optimiser recognises this, and eliminates any writes to member variables
inside the destructor, since it knows they cannot legally be read later.
BoundaryTagManager relied on ~FreedBlock resetting its memory to 0, so
this optimisation broke it. Replace the placement new/delete with plain
non-magic Setup/Reset functions, to avoid the optimisation.
Fixes#2481.
This was SVN commit r15334.
This way we do not have two error messages when starting Atlas, but the
dynamic Atlas lib is not available.
Patch by Gallaecio. Fixes#1540.
This was SVN commit r15301.
Does not account for setting rally points on units that can move into
the FoW/SoD.
Recalculates paths even if the rally points are not displayed.
Refactors UpdateMarkers() to remove some indentation levels.
Based on patch by Itms. Fixes#1257.
This was SVN commit r15288.
I guess changes to the map loading sequence caused the TerrainChanged
message to be sent before the map was switched from square to circular
instead of after. The pathfinder didn't notice the switch, so it
continued treating the map as if it were square, allowing units to walk
into the permanent map-corner SOD and vanish, and allowing territories
to expand into the SOD.
Tell the pathfinder explicitly when the map shape changes, so it can
discard its cached data correctly.
This was SVN commit r15277.
Fixes potential infinite loop if worker thread was running but not
enabled.
Fixes apparent bug in fading sound smoothness.
Cleans up worker class slightly.
Cleans up weird and inconsistent whitespace.
This was SVN commit r15269.
Instead of each CCmpVisualActor rendering itself individually, collect
all the units in a single CCmpUnitRenderer. This avoids the overhead of
doing Interpolate/RenderSubmit calls every frame for every object in the
world. It also allows more efficient culling.
CCmpUnitRenderer knows the positions of each object at the start and end
of each turn, and computes the bounding sphere of the object along that
path. That allows quick culling without recomputing the precise
interpolated transform every frame. (In the future it could be improved
much more.)
Clarify and clean up the sending of PositionChanged messages, and add
new InterpolatedPositionChanged.
Remove the forceFloating parameter from GetInterpolatedTransform, since
it doesn't fit the new design. Replace it with a (non-synchronised) flag
in CCmpPosition.
Move construction progress from CCmpVisualActor to CCmpPosition, so that
it consistently affects all position/transform computation.
Refs #2337.
This was SVN commit r15265.
Deserialize SYSTEM_ENTITY before any other entities. This makes it safe
for Deserialize() methods to access system components (mirroring how
Init() can already access system components).
Add a Deserialized message, sent after all entities have been
deserialized, to help with some other sequencing problems.
This was SVN commit r15264.
This allows component Init functions to make use of the terrain
immediately, instead of delaying some computations until the first
frame.
This was SVN commit r15262.
BoundingSphere is similar to a bounding box, but more spherical.
SOverlaySphere is useful for visualising BoundingSphere (it's quite
inefficient and should only be used for debug functionality).
Normalise the camera frustum clipping planes, so that IsSphereVisible
gives the correct result.
This was SVN commit r15261.
