c9578ae72d - create vertex buffer data for horizon portals in the constructor instead of in the draw function. 
This was the last remaining place where the vertex buffer was accessed in the render pass.

597e10116f - added missing framebuffer function to fudging block. 2016-08-26 08:30:47 +02:00

f6544f3c44 - removed unused GLFLat::sub and all codes depending on it a valid pointer. 2016-08-26 00:04:29 +02:00
Christoph Oelckers
6755cb2a25 - use the quad drawer for skybox-flagged sectors. 2016-08-26 00:02:32 +02:00
Christoph Oelckers
b83c2056a8 - store the stencil caps in the reserved part of the main vertex buffer instead of constantly recreating them. 2016-08-26 00:01:51 +02:00
Christoph Oelckers
76d7b52fcd - handle the case where a wall gets drawn with an unmapped buffer and no vertex data. 
This uses the quad drawer because it can only happen with translucent walls that got split during sorting.
 2016-08-25 23:20:23 +02:00
Christoph Oelckers
4598c4138c - added vertex initialization for walls in the processing pass for core profile without persistent buffers. 
This is slower than doing it in the render pass so it's only active when actually needed - it's also slower than using a client array so this code only gets used when there is no choice but to work with a 3.x core profile context.
 2016-08-25 23:13:49 +02:00
Christoph Oelckers
8f331f56e2 - use MakeVertices directly in the portal code and remove all related code from RenderWall. 2016-08-25 23:02:43 +02:00
Christoph Oelckers
8cf53f04e8 - split off the vertex creation from RenderWall. 2016-08-25 22:54:08 +02:00
Christoph Oelckers
4ab8ca63ce - use more desctiptive names for the predefined vertex buffer indices. 2016-08-25 22:23:31 +02:00

Christoph Oelckers
9555617816 - fixed: The default for position.w is 1, so gl_quaddrawer.cpp needs to set this, too, for the uniform vertex positions. 2016-08-22 22:02:02 +02:00

Christoph Oelckers
250be72939 - added handling for drawing with uniform vertices. It draws something but in the wrong place. Right now I have no idea what's happening... 2016-08-22 15:31:23 +02:00
Christoph Oelckers
7ba5acfb35 - added quad drawer interface so that this part can be done without altering a vertex buffer. 
So far it's only the framework, the new code is not active yet.

Christoph Oelckers

353a464f5b - fixed: The 2D texture drawer did not reset the render state's color so any previously set desaturation would persist. 2016-08-13 22:15:00 +02:00

56a60ebe85 - restored a line that got accidentally deleted. 2016-08-08 20:47:54 +02:00
Christoph Oelckers
e5f88a9883 - fixed: The textured automap was not using correct light levels. 
In order for the externally passed vertex attribute to work the buffer's color attrib array needs to be disabled for these.
 2016-08-08 16:18:07 +02:00
Christoph Oelckers
675822004d - use static buffer data and a uniform to handle the texture positioning of the present shader. 
That's again one less write access to the buffer. The uniform method was chosen because this way a buffer update can be completely avoided, and setting a single uniform is a lot cheaper and simpler to handle.
 2016-08-08 16:06:02 +02:00
Christoph Oelckers
8daaf61160 - predefine the vertex data for the blend overlay which will never change throughout the lifetime of the GLRenderer object. 2016-08-08 14:24:48 +02:00
Christoph Oelckers
9c9edbffdb - on older ATI drivers where the clip planes are broken, only disable the clip planes themselves, but not OpenGL 3.x so that dynamic lights still work as intended. 
- only disable clip planes on Windows, but not on Linux or macOS.
- If a driver reports full OpenGL 4.5 support, assume that all features are working properly.

8f0629932d - ImmRenderBuffer is not needed anymore. 2016-08-06 14:29:21 +02:00
Christoph Oelckers
6a66d0255d - use a dedicated vertex buffer for rendering the wipes. 
- fixed: The postprocessing shaders clobbered the render state's vertex buffer info by bypassing and not notifying it of the change.
 2016-08-06 14:12:40 +02:00
Christoph Oelckers
7576e85cef - force use of shaders on all hardware, unless -noshader is specified. 
Right it's only for easy testing, so only the code that does the feature checking has been disabled.
 2016-08-06 13:06:55 +02:00
Christoph Oelckers
2e555e6dab - use client arrays on compatibility profiles instead of calling glBegin/glEnd. 
This eliminates most behavioral differences for FFlatVertexBuffer between both operating modes, now the only difference is where the buffer is located.

13a2bf57e5 - fixed vertex coordinate ordering for the sky cubemap. 
This was done differently for FFlatVertex and FSkyVertex which caused a switch of the y and z coordinates for the skybox image.

Christoph Oelckers
63ad7d99d1 - fixed: The dynamic light buffer's behavior needs to obey the gl.lightmethod variable, and not depend on presence of persistently mapped buffers. 
Since there is a command line switch to revert to the lower behavior it can well be that they do not match.
 2016-08-04 12:55:21 +02:00

54a120d612 - do not process subsectors if rendering a stacked sector portal and the clipper is set to 'blocked', i.e. no visible parts are present. 
This solves the most severe occurences of sprites being drawn in front of a portal's contents. It is not a full fix, though, there's still some extreme cases where portals may glitch if some stuff gets between the camera and the actual portal area.
Normally this has to perform a full check of the subsector against the portal's camera-facing linedefs but that's too costly for those rare cases where it may be an issue.
 2016-07-23 10:23:34 +02:00
Christoph Oelckers
d405cf5b7c - fixed: Before rendering a sector stack portal the clipper needs to be completely filled, if the view point's subsector is not inside the portal. If this is not done, some setups where a recursive look into the originating area is possible may exhibit some issues. 2016-07-23 09:47:14 +02:00

bc7b439dd0 - addressed: MDL_INHERITACTORPITCH got the direction of the rotation wrong. Fixed by deprecating this flag (and also MDL_INHERITACTORROLL) and introducing proper flags, named MDL_USE*. This not only resolves the issue but also elimintates the nonsensical INHERIT part of the names. 2016-07-16 09:10:18 +02:00

f4b80a451e - fixed: The render style specific blend settings were overridden when adding code to ensure proper setup of all properties. 
It turned out that the only thing that wasn't set is the alpha function, not the blend settings themselves.

e56196eb1a Disable facing camera rotations if the actor is a flat/wall sprite. 
- It not only looks bad, it also throws off users when trying to make perfectly aligned images since the plane is distorted wildly.

cc8d84cd5d Fixed sprites defaulting to rotate around the center instead of the offsets. Seeing how it's still useful however, ROLLCENTER can still be used to center upon actors that are offsetted like monsters. 2016-07-13 09:31:22 +02:00

17c212d5bc - disable transparent door render hacks if any of the involved sectors contains floor slopes. 
These lead to false positives but rarely represent actual hacks.

7b99c883e1 - use the exact same semantics and methods to handle player visibility as in the software renderer. 
This fixes invisible player sprites in recursive line portals.

This adds support for the new weapon state code and fixed some lighting calculations.
Note that this currently will not allow combination of HUD models with other sprite frames yet.

52e19c59b3 Revert "- let gl_draw_sync default to false." 
This reverts commit 616f84209b.

Now I remember why this is not active: This is causing some problems with interpolated plane heights. Since there is no synchronization with the vertex buffer, the next frame will reset all plane coordinates before the GPU can use them. This will require some rethinking about when to update the buffer - it cannot be done in the render data setup loop.

99bfc64af6 - another failed attempt to use GL_CLIP_PLANE. Leave it in because it's closer to what is needed than the old code. 2016-05-12 23:41:06 +02:00

616f84209b - let gl_draw_sync default to false. 
No need to waste valuable processing time if we can let the GPU run in parallel with the code that generates the next frame.
