83aa5759a2 Split up the trail fragment shader.
The barycentric shader is generally useful for debugging.

299f305453 Update the trails code to use shader effects.
Trails was actually the reason I started that project. This is just cleanup
after rebasing.

bb022bc4fc Reverse the trail vertex order.
That webgl app was designed for GL's default of CCW for front faces, but
quake wants CW. Now the disable/enable of face culling isn't necessary.

1a06712405 Handle the singularities on the trail vectors.
They're actually guaranteed for the first and last segments due to the
first and last points being duplicated in the buffer (simplifies design).
This also handles the rare case where a vector appears to go directly into
or out of the screen.

Everything works nicely if only one of n1 or n2 is 0, and for the very rare
case of both n1 and n2 being 0, then a final normal of 0 is reasonable.

2fbab084a1 Build and draw solid trails for rockets.
And lava balls (handy test, actually).

bd3647d671 Put the trail frag shader into debug mode.
This draws the wire-frame of the trail. Yay Florian Boesch.

ddf4ff871f Make the entity param to trail functions non-const.
Needed for adding trails to entities.

ddd8885cd6 Start working on solid trails for smoke etc.
The implementation is based on
http://codeflow.org/entries/2012/aug/05/webgl-rendering-of-solid-trails/

The shaders have been written and compile and link. The next step is to
generate some data for them.

3efb0c538f Separate file search from loading.
QFS_LoadFile (and its wrappers) now  take a file handle rather than a
path. This will make vpath usage a little cleaner to implement.

4d59282641 Find the remaining vertex attribute order issues.
I hope. I do need to figure out why I made sprite blend an attribute
rather than a uniform.

a5db0b1a65 Remove the now unnecessary GLSL_CompileShaderS().
Now that the transition to using shader effects is comlete, there's no
need for the wrapper.

a419fb2c92 Ensure the vertex coord attribute is attribute 0.
It seems mesa still has the bug where non-array attributes don't work
when set as attribute 0, and that the allocation order changed sometime
since I last tested with mesa. This fixes the black world and flickering
alias models on my eeepc.

042d6e5728 Remove a couple of stale files.
Missed these in the bsp related commit.

26fc0b74e6 Fix bsp water surfaces.
Everything seems to be working for the bsp renderer.

f43592589d Use the new shader system in the bsp renderer.
It mostly works. Skybox is untested, and water surfaces are broken.

b269338947 Start using the new shader system.
So far, alias model rendering is the only victim, but things are working,
even if only color map lookup and fog blending are broken out at this
stage.

I expect the effect naming scheme will go through some changes until I'm
happy with it.

323fbe1927 Fix an allocation oopsie.
I must have been tired when I wrote that line.

550f1ae788 Fix some bitrot.
Just updating for the changes to the ALLOC/FREE macros.

96c40cb9a1 Add basic support for shader "effects".
Again, based on The OpenGL Shader Wrangler. The wrangling part is not used
yet, but the shader compiler has been modified to take the built up shader.
Just to keep things compiling, a wrapper has been temporarily created.

6288684fa2 Fix more gcc 4.8 errors.
More actual bugs found, too.

88692f92d9 Fix the calls for Draw_Init in the gl renderers.
While namehack.h took care of the symbol mangling, I do prefer the calls to
be correct as it reduces confusion.

6d7f747577 Add timerefresh to the glsl renderer.
Also, tweak the formatting of the output for the other renderers (%g
instead of %f) and make gl's timerefresh output unconditional.

bc12567572 Clean out a leftover from the 128 dlight change.
I'd missed a set of bit->lightnum conversions that resulting in lightnum
becoming much greater than 128 and thus trashing memory when the surface
was marked.

e27d7cbd2d Handle alloca "correctly".
Use AC_FUNC_ALLOCA and the #ifdef mess suggested by the autoconf docs
(hidden in qfalloca.h).

f1aefc969d Fix some 64-bit mingw compile issues.
Just one more issue to fix (alloca), but with a hack, QF compiles (no clue
yet if it works: wine doesn't seem to be an option at this stage)
2013-01-22 21:02:49 +09:00

cb45d248c4 Use the Mersenne Twister for particles.
The seed is currently 0xdeadbeef, but I intend on fixing that soon. Now the
particle velocities and origins use fully independent bits (though a big
chunk is wasted right now).

Bill Currie
3de67589a3 Fix random particle origin/velocity z component.
This is a quick fix until I get a random number generator into QF.

Mingw's RAND_MAX is only 0x7fff and so the (((rnd >> 10) & 63) - 31.5) / 63.0
used for the z component of origin and velocity would never go positive.
For now, change the 10 to 9 (reusing another bit from Y). I plan on
implementing a full 32-bit PRNG in QF so we always have a reliable
generator.

3cb0f3e183 Remove viddef in favor of vid in the renderers.
This fixes the status bar refresh issues in sw. The problem was that with
two viddef's hanging around, things got a little confused and recalc_refdef
wasn't getting into the renderer.

a05e7253e4 Force a full update when the fade screen is drawn. 2013-01-13 20:34:39 +09:00

0c81364da8 Fix scr_copyeverything in gl and glsl.
Now the gl renderers unconditionally set it to 1. This is required because
the screen is cleared every frame.

4a95f89760 Correct the handling of r_viewsize and lineadj.
r_viewsize is meant to be clamped to 100, but not limit linadj.

86b95629cf Complete the move of some vars into vid_render_data.
scr_fullupdate and scr_copyeverything were missed. Possibly others too, but
this is enough for the moment.

82a6861233 Move the call to VID_Update out of the if blocks.
This makes it obvious that VID_Update is unconditionally called when
SCR_UpdateScreen is called.

5bbb76194f Use stdlib.h instead of alloca.h.
While the manpage does say alloca.h, that's not very portable, it seems.
stdlib.h seems to be better (at least for mingw, anyway)

751417ffb2 Rename R_RecursiveWorldNode to R_VisitWorldNodes.
Finally, the name reflects its actual purpose.

a852eeb711 Remove the recursive versions of R_RecursiveWorldNode.
They seem to not be needed any more.
