437dd68d79 - the Render state must be applied before performing a portal clear screen, because it would still be set to stencil drawing at this point. 2017-05-14 12:42:25 +02:00

ef7e4fe678 - draw empty portals in black, not the last set color. 2017-05-14 12:31:51 +02:00

9a24771a7d - refactored FDynamicColormap out of sector_t.
This has increasingly become an obstacle with the hardware renderer, so now the values are being stored as plain data in the sector, with the software renderer getting the actual color tables when needed. While this is a bit slower than storing the pregenerated colormap, in realistic situations the added time is mostly negligible in the microseconds range.

d72623b9b5 - eliminated global in_area variable.
Removing this made me realize that calling the renderers' FakeFlat functions from the automap is inherently unsafe with the recent refactorings because there is absolutely no guarantee that the data may actually still be defined when the automap is being drawn.
So the best approach here is to give the automap its own FakeFlat function that runs independently of render data and assumptions of data preservation. This one can also be a lot simpler because it only needs the floor, not the ceiling info.

4c61048278 - moved gl_fixedcolormap into GLSceneDrawer.
This means that one of the most extensively used global variables is gone.

0aa0db637c - started adding a SceneDrawer class to the OpenGL renderer.
This will eventually hold all the global variables for the rendering.

921abc404d - fixed GCC warnings and errors
(Is there anyway to tone down GCC's warning level? It outputs too many false positives for potentially uninitialized variables in which the genuine errors get drowned.)

4ed5b91b0f - added a few missing includes which were not triggered as error in a debug build. 2017-03-10 09:57:10 +01:00

d2beacfc5f - except for DWORD, all homegrown integer types are gone - a handful were left where they represent genuine Windows types. 2017-03-09 19:54:41 +01:00

acf66d9f8f - fixed some edge cases with visible player sprites through non-static line portals. This required reinstating some code which I thought was no longer needed. 2017-01-07 15:44:38 +01:00
Christoph Oelckers
a000b57204 - fixed player visibility determination by tracking and translating the actual actor position in addition to the camera position through portals. I hope this fixes the randomly appearing player sprites for good. 2016-12-29 22:19:09 +01:00

f52744e8a4 - fixed: When looking through a plane mirror the portal plane exclusion logic needs to be flipped, because the mirror inverts the vertical view direction. 2016-12-29 19:54:38 +01:00

4eb5f10b02 - use normals to have proper light attenuation. So far only implemented for walls and flats. Models are planned but need some thinking about how to efficiently collect all required lights for an object. 2016-10-03 16:09:32 +02:00

750c194959 - changed order of SwapBuffers and glFinish call. The new order with glFinish coming last is recommended by OpenGL and it fixes a stalling problem with portals and camera textures visible at the same time.
- check and use WGL_EXT_swap_control_tear extension. The above change makes the system always wait for a full vsync with a wglSwapInterval of 1, so it now uses the official extension that enables adaptive vsync. Hopefully this also works on the cards where the old setup did not.

8b6e09ca09 - changed the license of the OpenGL renderer to LGPL v3.
This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.

a5c0f9a548 - use the predefined fullscreen vertices for clearing a portal instead of using the quad drawer. 2016-09-06 11:58:22 +02:00
Christoph Oelckers
217601f338 - fixed: FPortal::ClearScreen may not use the 2D drawing code anymore.
2D calls are accumulated and then executed all at once at the end of the frame, but this one needs to be interleaved with the 3D rendering. It now uses the quad drawer to fill the portal with blackness.

0f0dc2c852 - implemented buffers for GL 3.x. These only get mapped during the data collection pass so the order of some things is different here. 2016-08-29 10:43:03 +02:00

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.

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

8f331f56e2 - use MakeVertices directly in the portal code and remove all related code from RenderWall. 2016-08-25 23:02:43 +02:00

4e8a96aa0e - removed FRenderState::set2DMode because it had no effect. This looks like development garbage from old times. 2016-08-14 09:14:26 +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.

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

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.

d84e079282 - render partial sprites oon the back side of a portal for actors in front of it. This is needed because the stencil will clip away those parts. 2016-04-30 16:57:53 +02:00
Christoph Oelckers
70bf649364 - added clip planes for line portals and mirrors. This should eliminate the remaining problems with some visible geometry in front of the portal, it is also necessary to handle sprite splitting across line portals properly. 2016-04-29 12:26:57 +02:00

09f54b0940 - cleaned up the clip plane management for portals.
Unfortunately the math behind the old clip planes is utterly impenetrable and so poorly documented that I have no idea how to set that up, so it is deactivated for now. It wasn't working anyway.

0a35027f67 - fixed use of validcount for the GL renderer.
This needs to be incremented more locally to the place where it is used, so that it is guaranteed that each viewpoint that needs to be rendered increases it.
As a result the uses in the portal code could be removed.
