1437cbec91 Make the face culling a little more sensible.
GL Quake was weird, culling front faces. Partly understandable, since
Quake's front order is clockwise and GL's default order is
counter-clockwise. However, since the order can be specified, that should
be done instead. Thus, specify the winding order as clockwise (for quake's
data), set culling for back-face removal, and then mess with the winding
direction in the mirror and fish-eye code.

62e564c5cd Send ALL of the model's verts to GL.
Triangles have 3 vertices, not one :P

baab15279f Correct the alias vertex data types.
Vertex locations need to be unsigned byte rather than byte (GL is funy
with that). s and t need to be at least short, and since the normal index
is embedded in the st vector, it needs to be the same type. With this, my
test tetrahedrons seem to be working.

c378acab6b Actually load up the mvp and normal matrices.
Rather critical. I thought I'd done that :/

86edf54c40 Build and ignore cleanups
GLSL renderer build was checking for BUILD_GL instead of BUILD_GLSL in a
few places. Also, ignore the GLSL .fc and .vc files and the binaries.

2a3151cecd Hook in alias model drawing.
Nothing is visible yet.

72e3a8d507 Merge sw and sw32 alias frame selection.
I'm leaving GL for later because lerping complicates things. I'll sort it
out when I implement lerping in GLSL.

1c480bf75e Merge the alias skin selection code.
We really don't need 4 copies of identical code when 1 will do :P

540bccbc27 Load all the alias vertex data as bytes.
I had forgotten I wanted to do it this way.

df3d9fe4df Correct the fullbright start color extraction.
I don't know what despair and I were thinking, but we obviously didn't
understand the colormap code at the time.

7be08534be Clearify the program dump info a little.
Calling programs shaders was a little confusing when I use shader to refer
to the sub-programs (vertex and fragment shaders). Also, print the program
number as well.

2ad5aa7aed Unbind the array and element array buffers when done.
Not doing so wreaked havoc on my 2d rendering (what's he doing here, and
why's he messing with my redering? ;)

d1419c30db Make a start on alias model rendering.
The vertex and fragment shaders are written, and R_InitAlias is stubbed,
but that's it so far.

718595db45 Implement sprite rendering.
Sprite interpolation seems to work, even :) (maybe)

091e16f9d2 Bring in GL's R_RecursiveWorldNode as R_VisiteWorldNodes.
No surface queuing is done, but entities get queued.

55e53b796d Make a start on getting sprites rendering.
The plan is to do interpolated sprites based on a discussion I had with
LordHavoc about them: blending between the two sprite frames. He didn't
mention it, but it looks like blending between the sprite frames' verts is
necessary too.

16f84cd496 Hopefully get the 3d view and projection transforms setup. 2011-12-30 21:10:24 +09:00

20d93466c7 Frag some magic numbers.
More annoying than hipnotic's gremlins.

35bf957d08 Add a 4x4 matrix type and some functions for it. 2011-12-30 20:11:53 +09:00

edb05fdfce Rename Vector3Scale and QuatCompScale.
They are now VectorCompMult and QuatCompMult.

bcdcd7b36d Implement sprint glsl loading.
That was... easy.

a87a60a6fd Flush the text buffer before drawing conback or menus.
Ok, now really done until I notice something else (I forgot this one
momentarily).

047b7bcc32 Implement Draw_TileClear.
With this, 2d seems to be finished. YAY.

a1035aafe9 Implement Draw_TextBox. 2011-12-29 17:51:31 +09:00
Bill Currie
2b44a25c6b Flush console text after each screen function.
This on its own doesn't fix menus being overwritten with console text, but
it's an important step.
2011-12-29 11:26:14 +09:00

9fec4d5be0 Implement Draw_Fill.
Almost there with 2d.

9d0ed6b885 Fix the missing text.
Silly case and paste error cleared out my text vertex array prematurely.

e69a583f1b Work around a bug in mesa.
Since I'm not specifying the api when creating my context, mesa is giving
me GL2. This is fair enough, but in GL2, vertex attribute 0 is the vertex
position. This too, is fair enough. The problem is, mesa is assigning 0 to
my vcolor attribute and thus I can't set it. The work around is simply to
swap the declaration order of vcolor and vertex (this really shouldn't work
eiter, I suspect).

6a44978a0f Fix reading of GL_CURRENT_VERTEX_ATTRIB.
Turns out it returns a vec4. oops.

b657905c83 Bring in Despair's gl error checking from the gl renderer. 2011-12-28 09:05:36 +09:00

151cc05882 Add support for vertex colors.
As I need to control the alpha, they're sent as rgba rather than quake
palette indices. Text works well. All other 2d stuff does not :(.

b96ca6f0e0 Add QuatCompScale and fix a bug in QuatScale. 2011-12-28 08:59:52 +09:00

b943b6d6e8 Implement crosshairs, mostly.
Colored crosshairs aren't supported yet (next).

db8573b774 Make the cross-hair data sharable between renderers. 2011-12-26 21:43:15 +09:00
Bill Currie
705d07fa39 Implement most of the 2d rendering functions.
textbox, crosshair, tileclear, fill and fadescreen are the remaining
functions.

There's a problem with 2d icons being drawn over the text (instead of
under), but I'll leave that for later.
