Do some intersection tests on the CPU so that the silhouette render
passes only have to draw models/patches that might actually contribute
to silhouettes, saving the CPU and GPU cost of rendering more objects
than necessary.
This was SVN commit r15483.
Remove commented out code writing triggers that has nothing to do with
the actual triggers implementation.
Free memory that was allocated for error reporting when when fork()
fails.
Remove dead initialization.
This was SVN commit r15477.
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.
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.
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.
For unknown reasons, sometimes glTexSubImage2D acts as if
GL_UNPACK_ALIGNMENT = 2 or 4, instead of 1. This causes the odd-sized
array uploaded for the LOS texture to be interpreted incorrectly, and
the LOS texture gets rendered very incorrectly.
Pad the array to a multiple of 4 in all cases, so that
GL_UNPACK_ALIGNMENT shouldn't affect it.
Hopefully fixes#2594.
This was SVN commit r15216.
The tests crashed on my Debian systems but not on my Ubuntu system.
The crash happened in line 142 of SpiderMonkey's ThreadLocal.h.
I know that I had to use a workarounnd for contexts to avoid destroying
the context that was created first. I also had in mind that in newer
versions a JS_Init function got introduced which presumably solves this
kind of issues.
Based on this experience I assumed runtimes could have a similar problem
and this patch indeed fixes the issues.
Unfortunately the correct usage of JSRuntimes in that regard is not
documented.
There's only a rater misterious comment in JSAPI.h which hasn't been
cleared up so far and is most likely completely outdated
(https://bugzilla.mozilla.org/show_bug.cgi?id=992641).
This was SVN commit r14995.
This commit contains all the required changes to our source files and
build scripts (hopefully).
A next commit will remove the old stuff of SpiderMonkey 1.8.5.
Spcial thanks to:
- H4writer who helped a lot mainly with the performance issues we
had/have, but also with other problems or questions.
- Leper for the review.
- Historic_bruno for implementing the build scripts on Mac OS X and
testing on the Mac.
- The people from the #jsapi channel and from
mozilla.dev.tech.js-engine who answered a lot of questions and helped
solving problems.

Remove waves for now as they were unsatisfactory.
Removes "shininess" as a water parameter as it was basically useless.
Add a button in Atlas to recompute water parameters so you can now see
fog in Atlas.

Refs #1875, #2114, #48.
This was SVN commit r14514.
Each GUI Page gets its own compartment and all ScriptInterfaces in the
same thread should now use the same JS Runtime.
This is required for the SpiderMonkey upgrade.

This was SVN commit r14496.
Replaces glBegin/End with glDrawArrays, GL_QUADS with GL_TRIANGLES, and
replaces glPush/PopAttrib by resetting the viewport manually.
Adjusts GLSL shaders for these changes.
This was SVN commit r14152.
Add optional clipping rectangle to CTextRenderer. Strings that are
printed
outside the vertical extent of the clipping rectangle will be
immediately
skipped. This greatly reduces the cost of large scrollable text boxes.
This was SVN commit r14019.
When CTextRenderer is given multiple strings with no differences other
than position, render them in a single glDrawElements call to reduce
driver overhead.
Also avoid some unnecessary copies of std::wstrings.
This helps performance a bit with large GUI text boxes.
This was SVN commit r14018.
Replace unifont with CFont and CFontManager, since the h_mgr interface
was
needlessly inconvenient.
Load the font textures through CTextureManager, to support dynamic
reloading (e.g. when resetting GL state - see #741).
Add CFontMetrics as a convenient wrapper for code that just wants to
measure text.
Fixes#1117.
This was SVN commit r14016.
When textures.xml specifies format="alpha", the input is expected to be
an
8-bit greyscale PNG, and the output will be an 8-bit uncompressed
alpha-only DDS.
Add format override to CTextureProperties, to select between e.g.
GL_ALPHA
and GL_LUMINANCE for 8-bit textures.
This is needed so fonts can use the new texture system.
This was SVN commit r14015.
Implements custom, VFS-based map load/save dialogs for Atlas (replaces
broken native file dialogs), fixes#631, #889.
Fixes map loading/saving to handle arbitrary subdirectories for better
organization.
Adds default settings to Atlas player panel, fixes#1872. Each setting
now has a checkbox to choose whether it should be saved with the map
(avoids writing lots of useless default data for each map).
Adds map preview setting to Atlas, refs #1745.
Cleans up and simplifies some duplicate code.
Fixes optional serialization performance test.
This was SVN commit r13938.
Use an arena allocator in ShaderModelRenderer::Render, to reduce
the allocation cost in STL containers.
Avoid unnecessary copying of std::vectors.
This was SVN commit r13911.
Switch all the constant strings in graphics code to use the new
variables.
This avoids the cost of instantiating CStrInterns at runtime every
frame.
This was SVN commit r13906.
CShaderDefines is designed to be efficient to copy and compare, but not
to construct. Conditional defines were constructing new CShaderDefines
for many models every frame.
Precompute all the possible conditional combinations of CShaderDefines
when a material is first loaded, so they can be looked up at no cost
when rendering.
This was SVN commit r13902.
