Without this, some code will enable (and set other parameters for)
whatever random texture unit the previous stage had selected. This can
break any fixed-function rendering, since either it will not have
enabled the correct texture unit, or its correct setup will be
interfered with by another texture unit that shouldn't be enabled. (This
doesn't affect ARB/GLSL shader rendering, since they don't care about
the enabled state, but the GUI (and some debug things) are still FFP in
the default ARB mode.)
Fixes#2833 (in which the fancy water shader selected texture units 5/6,
which then got enabled, and remained enabled forever).
This was SVN commit r16372.
This fixes the problem where passing a non-ASCII string to
debug_printf(L"%hs", s) caused vswprintf_s to fail on Linux (because it
doesn't know what encoding the char* is meant to have). Now debug
messages will remain as UTF-8 until they reach the OS.
Fixes#3021.
This was SVN commit r16332.
Some meshes (e.g. pers_gardens_struct with gentangents enabled) have
>32K vertexes, and won't fit in a 2MB VBO. 0ef6c7555e had reduced them
from 4MB to 2MB. So just make the VBOs bigger again, and try not to
worry about the waste of memory.
Fixes#3026, #3042.
This was SVN commit r16309.
Some drivers (at least the Intel drivers on Windows) are slow at
incrementally updating a VBO with hundreds of calls to glBufferSubData
every frame. Performance is significantly better if you use
glBufferData(NULL) to tell it to discard all the previous contents, and
then re-upload all the data at once.
Update CVertexBuffer so that GL_DYNAMIC_DRAW/GL_STREAM_DRAW buffers are
handled with the new mechanism. This requires the caller to hold onto
the backing store so it can be re-uploaded when necessary, and needs a
bit more signalling to indicate exactly what needs uploading.
I see an improvement from roughly 60 to 75 fps on Intel HD Graphics
3000, Windows, 1024x768, Siwa Oasis.
This was SVN commit r16241.
This reduces the total number of different vertex sizes in the system,
allowing more data to share a single CVertexBuffer, therefore reducing
the amount of wasted space in each CVertexBuffer and reducing VRAM
usage.
This was SVN commit r16230.
Everything is char* now, so we don't need to mess around with different
string types.

This needs to use the model-view matrix, not model-view-projection (the
transform uniform), else the axes won't be unit vectors and the particle
sizes will be wrong. But GLES doesn't have the pre-defined matrices, so
pass it in explicitly.
This was SVN commit r16165.
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.
Change the shader itself so that the effects look nicer and are more
consistent across settings.
Rework the water mesh generation (simpler system). Fix a few issues.
May work oddly with Atlas since I haven't been able to compile yet.
Refs #1875 (maybe fix), Fixes#2077 (I'll assume it does), Fixes#2114
(assumption again), refs #48.
This was SVN commit r15473.
Fix a long-standing typo in TerrainRenderer for water rendering that
apparently had no effect.
Don't compress the water textures to make it look better. They will be
changed anyhow.
This was SVN commit r15461.
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.
