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.
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.
Let materials specify shader uniform values.
Use interned strings for shader uniform/attribute names.
Remove confusing float* cast operator on CVector4D.
Simplify and clean up CVector4D.
Remove non-supported 'old' lighting model.
This was SVN commit r11453.
Add shadow filtering (PCF) option.
Fix ugly shadow saturation in old lighting mode.
Fix fancy water shader.
Fix camera matrix computation.
Support scissoring of camera frustum.
Optimise vertex skinning.
Inline various matrix functions.
Support filtering of the list of submitted models before a rendering
pass, for more precise culling.
Optimise water renderer (fixes#721, based on patch by ortalo).
Use scissoring when generating reflection/refraction textures.
Skip reflection/refraction texture generation when no water is visible.
Render alpha-blended objects differently (fixes#434).
Reduce shadow swimming effects.
This was SVN commit r9814.
Add shift+wheel (and Q/E, and ctrl+arrows, and ctrl+WASD) to rotate the
camera.
Restrict the rotation and zoom to narrow ranges. (Constraints can be
disabled in the dev overlay).
Smooth the movement and rotation.
Fix some stupid whitespace.
Fix some const correctness.
This was SVN commit r7930.
this snowballed into a massive search+destroy of the hodgepodge of
mostly equivalent types we had in use (int, uint, unsigned, unsigned
int, i32, u32, ulong, uintN).
it is more efficient to use 64-bit types in 64-bit mode, so the
preferred default is size_t (for anything remotely resembling a size or
index). tile coordinates are ssize_t to allow more efficient conversion
to/from floating point. flags are int because we almost never need more
than 15 distinct bits, bit test/set is not slower and int is fastest to
type. finally, some data that is pretty much directly passed to OpenGL
is now typed accordingly.
after several hours, the code now requires fewer casts and less
guesswork.
other changes:
- unit and player IDs now have an "invalid id" constant in the
respective class to avoid casting and -1
- fix some endian/64-bit bugs in the map (un)packing. added a
convenience function to write/read a size_t.
- ia32: change CPUID interface to allow passing in ecx (required for
cache topology detection, which I need at work). remove some unneeded
functions from asm, replace with intrinsics where possible.
This was SVN commit r5942.
Also fixed sectorDivs so it's always initialised, since the complaints
were annoying.
Camera: Added a const.
Super cavalry: Added required(?) aura attributes.
This was SVN commit r3906.
Map XML: Store camera position. Stopped using DTDs (because they make it
too hard to change the XML structure without breaking all the old XML
files).
Game.h: Include fewer files, to make compilation sometimes faster.
World: Changed some things to not be singletons, since they were
(ab)used as CWorld members.
This was SVN commit r3670.
