Bill Currie fb10f38fd4 SW now tries (but fails miserably) to render iqm models. 
Something seems to be very wrong with the transforms.
 2012-05-18 23:31:14 +09:00
Bill Currie da87ac0ce5 Remove some unused parameters. 2012-05-17 21:33:22 +09:00
Bill Currie da313cfae7 Load iqm models in the sw renderers. 
sw32 loses 32 bit textures :/
loading is /slow/ (converting rgb(a) to 8bit palette... ouch.
 2012-05-17 21:17:48 +09:00
Bill Currie 7637f35616 Remove the test scaling. 
Heh, forgot to remove it again :)

Bill Currie c3801d46e5 Render iqm models in GL. 
There are still many issues to sort out, but the basics are working.

Problems:
	rendered fullbright (no lighting done)
	normals are ignored
	extra textures (glow etc) not used/loaded

4 models on the screen don't seem to be a problem.

Bill Currie f958afad53 Optionally allocate extra data for iqm blend frames. 
Also, correct the blend parameter type (int->float. oops).
 2012-05-17 15:57:07 +09:00
Bill Currie 02f8aa6b75 Add Mat4MultAdd macro. 2012-05-17 15:56:01 +09:00
Bill Currie c0df07b607 Enable loading of iqm models in gl. 
They don't render yet, but the engine doesn't segfault.
The vertex blend indices are rewritten with blend palette indices.
 2012-05-17 15:55:38 +09:00
Bill Currie e722352a61 Add SYS_MODEL developer flag (8192) 2012-05-17 13:39:45 +09:00
Bill Currie 23284536b5 Move IQM freeing into common code. 2012-05-16 18:09:44 +09:00
Bill Currie 041d63c828 Move the frame blending into common code. 2012-05-16 17:44:18 +09:00
Bill Currie 8ada7c02a3 Remove the vertex scaling. 
It was there only because mrfixit is rather small (8qu?) and it made
finding him easier :). Anyway, any scaling should be done in the engine.
 2012-05-16 08:13:59 +09:00
Bill Currie 9984925fe8 Correct a comment. 2012-05-15 21:08:47 +09:00
Bill Currie 31772afd13 Add in some ambient light for iqm models. 
Though the bsp loader doesn't yet support colored lighting, the ambient
light will be colored when it does. With this, I guess iqm model support is
done for glsl until I figure out how I want to do dual quaternion support.
 2012-05-15 21:08:47 +09:00
Bill Currie 111377f1be Use buffer objects for iqm vertex arrays and elements. 2012-05-15 21:08:47 +09:00
Bill Currie 5740dba467 Mark iqm models as need-load when clearing. 
This fixes the segfault on map change.
 2012-05-15 21:08:47 +09:00
Bill Currie 0fd2b01665 Update the shader to work as it should :) 
I always thought it whould be "light - point" :P. Also, in normal maps, 127
is 0.
 2012-05-15 21:08:47 +09:00
Bill Currie c454b96d2a Translate lights into entity space. 
Finally, lights work "properly". Probably the nicest lighting we've ever
had :) (still have to put in ambient, though).
 2012-05-15 21:08:47 +09:00
Bill Currie 1375c3cf03 Finally, load textures for iqm :) 2012-05-15 21:08:47 +09:00
Bill Currie a032aa5adf Get the lights working (as such). 
They work nicely now when the normal map and texture are bypassed (don't
know what texture is getting used currently).
 2012-05-15 21:08:47 +09:00
Bill Currie 8c5e278bf8 Implement frame blending for iqm. 
Now that I have things working... :)
 2012-05-15 21:08:47 +09:00
Bill Currie c694b9f77e Add Mat4Blend macro. 2012-05-15 21:08:46 +09:00
Bill Currie a938c7fb14 Almost fix the animations. 
There's still a problem with his finger tips and feet, but the rest of his
limbs seem to be working well. Much thanks to Spike for encouraging me to
do a dump of the matices that are actually sent to the card.

It turns out that animated joints remain relative right up to the last
moment.
 2012-05-15 21:08:46 +09:00
Bill Currie 4ba69b511b Make quat_origin the right type. 
It's quat_t, not vec3_t :P.
 2012-05-15 21:08:46 +09:00
Bill Currie 202ab04572 Ensure the rotation quats are normalized. 
Doesn't make any noticeable difference, but it doesn't hurt.
 2012-05-15 21:08:46 +09:00
Bill Currie 31d89782ef Use the correct index variable when byteswapping the arrays. 
Not the cause of the broken animations :(
 2012-05-15 21:08:46 +09:00
Bill Currie 7cda91a879 Temporarily disable dual quaternions. 
The animation data isn't getting loaded or used properly (not sure yet).
This helps ensure it's not something I've done wrong with dual quats.
 2012-05-15 21:08:46 +09:00
Bill Currie 4b38048a5c Create functions for rotation and translation. 2012-05-15 21:08:46 +09:00
Bill Currie 5b4fdd2a93 Use the correct position for light calcs. 
I should have remembered that gl_FragCoord wasn't right.
 2012-05-15 21:08:46 +09:00
Bill Currie 2080c337d7 Avoid using malloc/free every model/frame. 2012-05-15 21:08:46 +09:00
Bill Currie c2e0674d50 Implement R_IQMGetLerpedFrames(). 
Like R_AliasGetLerpedFrames, but for IQM. It calcualtes the current frame
number and blend between the previous and current frames.
 2012-05-15 21:08:46 +09:00
Bill Currie 8387d987e2 Change position to vposition. 2012-05-15 21:08:46 +09:00
Bill Currie 099ef348c6 Advance the vertex attrib index. 
Disabling the array right after enabling it was causing things to just not
work :P
 2012-05-15 21:08:46 +09:00
Bill Currie d1d4c6142c Get the frame data from the right places. 
Always using joint[0] of the frames wasn't very useful.
 2012-05-15 21:08:46 +09:00
Bill Currie 74cb49ef7c Free the blended frame data. 2012-05-15 21:08:45 +09:00
Bill Currie 551dfc47fb Build the iqm vertex arrays in the correct order. 
They need to be built in ascending type order (makes life easier in the
renderer).
 2012-05-15 21:08:45 +09:00
Bill Currie bea8f8f9c4 Fix a segfault when searching for dlights. 
Uninitialized var bites my bum :P
 2012-05-15 21:08:45 +09:00
Bill Currie 2e98c31175 Check the corrent bits when reading scale frame data. 
Fixes the invalid reads when loading an iqm (at least for mrfixit).
 2012-05-15 21:08:45 +09:00
Bill Currie 9c69404163 Attempt to render iqm models. 
Things are a right mess (segfaults, invalid accesses on load, etc), but
hey, it's a start :)
 2012-05-15 21:08:45 +09:00
Bill Currie 15fd3be73a Allow iqm models when storing efrags. 2012-05-15 21:08:45 +09:00
Bill Currie a880f33152 Set the model type for iqm. 
Forgot this rather important step :P
 2012-05-15 21:08:45 +09:00
Bill Currie 41e7a6c70c Search for the "nearest" dlights. 
Nearness is a function of both distance and intensity: distant bright
lights can take priority over close dim lights.
 2012-05-15 21:08:45 +09:00
Bill Currie 0becd35b65 Begin work on rendering iqm models. 
No chance of working yet, but the shaders compile :)
 2012-05-15 21:08:45 +09:00
Bill Currie 078cb10caf Add a stride field to iqm_t. 
Since iqm vertex arrays are variable, and I don't want to calculate the
stride every time I render a model, cached the value used when building the
arrays.
 2012-05-15 21:08:45 +09:00
Bill Currie 15d35fbdc9 Add mvp_mat and some comments. 2012-05-15 21:08:45 +09:00
Bill Currie 59c5bf2f9e Code up an initial version of the iqm vertex shader. 
Probably more bugs than an old kitchen cupboard :P
 2012-05-15 21:08:45 +09:00
Bill Currie 6ab3bd45e5 Implement IQM animation loading. 
Bone poses are converted to dual quaternions + shear + scale for nice
skinning. Will likely be slow for software skinning, but too bad.
 2012-05-15 21:08:45 +09:00
Bill Currie 9a3206795e Add VectorUnshear(). 
VectorUnshear uses the exact same shear vector to remove shear from a
sheared vector. ie with:
  VectorShear (shear, v, w);
  VectorUnshear (shear, w, x);
x == v within fp math limits.
 2012-05-15 21:08:44 +09:00
Bill Currie bf38e6073e Implement iqm joint loading. 2012-05-15 21:08:44 +09:00
Bill Currie 9f253454e4 Implement and test Mat4Inverse(). 2012-05-15 21:08:44 +09:00
