various lighting code cleanups
- try to always make sure beam origin lights occur outside of model
- make Static_lights[] dynamic
- be sure to reset to first 8 lights when moving on to render spec related texture passes
- add ambient color to point lights (helps warp effects)
- sort lights to try and get more important and/or visible lights to always happen in initial render pass
As well as initialised in a different mode, bitmaps are stretched and for these modes
previously point filtered textures now use linear to keep them smooth.
I also had to shuffle some of the GR_1024 a bit.
Put my HT&L flags in ready for my work to sort out some of the render order issues.
Tided some other stuff up.
It doesnt use the backgrounds anymore but its still an improvement.
Currently it fogs to a brighter colour than it should because of Bob specular code.
I will fix this after discussing it with Bob.
Also tided up some D3D stuff, a cmdline variable name and changed a small bit of
the htl code to use the existing D3D engine instead of work around it.
And added extra information in version number on bottom left of frontend screen.
still needs a lot of work, ubt the frame rates were getting with it are incredable
the biggest problem it still has is a bad lightmanegment system, and the zbuffer
doesn't work well with things still getting rendered useing the sofware pipeline, like thrusters,
and weapons, I think these should be modifyed to be sent through hardware,
it would be slightly faster and it would likely fix the problem
also the thruster glow/particle stuff I did is now in.
cell shadeing has been added activated via the comand line '-cell',
3D shockwave models, and a transparency method I'm calling edge and center alpha that could be usefull for other things, ask for details
suport for seperate specular levels on lights and
optional strings for the stars table
code has been made more organised,
though there seems to be a bug in the state selecting code
resulting in the HUD being rendered incorectly
and specmapping failing ocasionaly
useing a phong lighting model I have made specular highlights
that are mapped to the model,
rendering them is still slow, but they look real purdy
also 4 new (untested) comand lines, the XX is a floating point value
-spec_exp XX
the n value, you can set this from 0 to 200 (actualy more than that, but this is the recomended range), it will make the highlights bigger or smaller, defalt is 16.0 so start playing around there
-spec_point XX
-spec_static XX
-spec_tube XX
these are factors for the three diferent types of lights that FS uses, defalt is 1.0,
static is the local stars,
point is weapons/explosions/warp in/outs,
tube is beam weapons,
for thouse of you who think any of these lights are too bright you can configure them you're self for personal satisfaction
