* Applying directional brightness profile value, disconnected spec flags and made specular light always equal to diffuse light
* Switched over to new command line arguments
* Wire lab up to new lighting controls, and provide backwards-compatible defaults for emissive.
* cleanup unused new function
* make static some functions that can be static
* revise command-line and emissive handling
* handled specular sun depreciation and general removal of specular value handling
* Removed specular light color as a separate value in the uniform buffers.
* cleanup of leftover/post-rebase specular references
* further post-rebase repair of light flags command line and leftover specular
* move techroom/selection/breifing 'room' lights to a common function and
augment lighting setup for current rendering
* fixed some mishandling of lighting modifiers.
* Addressed code clarity and comments from review
This was broken by the move to a single, global uniform buffer where we
started doing suballocation so offset 0 was reading bad data.
Also fixed a crash regarding an unknown locale name on Linux.
This is in preparation for using persistently mapped buffers for uniform
buffers. Since that functionality is not available in the OpenGL version
we are targetting I implemented a fall-back which simply uses
glBufferSubData.
I did a benchmark with these changes and there was no change in
performance to the current master version.
This changes the decal system so that it is able to modify the normal
map of the scene. I tested this with some existing normal maps but I am
not entirely sure if the tangent matrix I construct uses the right
values so some additional testing with normal maps made specifically for
decals would be good.
This also fixed the issues introduced by the changes to how directional
lighting was handled. Now a decal can have a diffuse and a glow map. The
diffuse map is used to change the values of the color buffer and also
supports ambient lighting. The glow map renders into the emissive buffer
and should be used for effects that should not receive lighting.
This allows to render screen space decals into the deferred lighting
buffers no matter how complex the underlying geometry is.
Currently there is only limited support for using this in the engine.
Only weapon impact decals are supported at the moment for testing
purposes.
