329f2eb9	2018-10-31T20:17:53	Fix crash when GL_LoadFunctions()/GLES2_LoadFunctions() fails https://bugzilla.libsdl.org/show_bug.cgi?id=4350 We can't safely call GL_DestroyRenderer() until GL_LoadFunctions() succeeds because we will be missing functions that we try to use when activating the renderer for destruction if we have an GL context.
62494a2e	2018-10-31T15:03:41	Merge SDL-ryan-batching-renderer branch to default.
da56cefa	2018-10-30T07:00:03	Fixed bug 4188 - Software renderer SDL_RenderCopyEx blits corrupt image under certain cases Sylvain Re-opening this issue. It fixes the test-case, but it introduces a regression with another bug (bug #4313). So here's a new patch that activate cropping of the source surface to solve the issue. It also reverts the wrong changeset. It prevents unneeded colorkey error message.
91820998	2018-10-28T21:36:48	Add and update include guards Include guards in most changed files were missing, I added them keeping the same style as other SDL files. In some cases I moved the include guards around to be the first thing the header has to take advantage of any possible improvements compiler may have for inclusion guards.
8340b0f0	2018-10-23T01:34:03	render: Add floating point versions of various draw APIs.
b262b0eb	2018-10-22T20:50:32	Small stack allocations fall back to malloc if they're unexpectedly large.
8c41e262	2018-10-13T03:36:42	metal: Fix SDL_RenderReadPixels to wait for the GPU to finish rendering to the active texture before reading its pixels.
d9094421	2018-10-12T17:55:42	metal: Fix high dpi and resizing on macOS, and clean up iOS code. Fixes bug #4250.
82c2f04e	2018-10-09T17:41:40	Fixed bug 4188 - Software renderer SDL_RenderCopyEx blits corrupt image under certain cases duckgrease SDL_RenderCopyEx blits wrong image (in some cases it's bunch of alternating horizontal lines, some cases it's image from the wrong coordinate, and in some cases it's just a bunch of garbled pixels), when the following conditions are met: - Use software renderer. - Enable either horizontal or vertical flip. - source and destination rectangles must have same width and height, and must be smaller than the size of the texture. - source rectangle's X and Y coordinates must be 0.

638d624f	2018-10-04T20:21:23	metal: Don't try to create a zero-byte vertex buffer. (Which will cause a crash in Metal, or an assert in the validation layer.)
1ecf4dfc	2018-10-04T16:34:44	render: Added SDL_RenderFlush().
09140bd8	2018-10-04T16:11:43	render: Move PSP backend to new interface. I have no idea if this works (or if it ever worked, having now examined this code), as I have no way to compile or test this. If it's broken, send patches. :)
9fedff99	2018-10-03T23:37:29	render: moved software renderer to new interface.
bd08a4e6	2018-10-03T19:05:20	render: D3D11 now cycles through 8 vertex buffers. This means it doesn't have to block while the current frame finishes using the vertex buffer; it just moves on to the next, probably-not-in-use buffer.
a9094a21	2018-10-03T18:23:53	render: D3D11 renderer patched to compile.
6e6f7382	2018-10-03T00:52:37	render: first (untested!) shot at converting D3D11 renderer to new interfaces. Probably doesn't even compile yet.
0c2e10dc	2018-10-01T22:53:45	render: Make the GL backends cache and defer more state changes.
fcb46813	2018-10-01T13:41:15	render: D3D9 doesn't need to check for stream offset support anymore. We don't use offsets at all now. Too slow.
709f5ee4	2018-10-01T11:32:08	render: Set the D3D9 stream source once and choose offsets during draw calls. This is _much_ faster than setting the offsets with SetStreamSource!

60afec79	2018-09-25T19:53:16	Removed redundant SDL_GetColorKey() call. (thanks Sylvain!)

d04e5524	2018-09-25T19:20:31	render: OpenGL renderer now caches some state, to improve non-batching mode. (other minor bug fixes in here, too)
06461bba	2018-09-25T17:04:47	render: Move non-batching flushes to different place. This lets us batch up a few commands that are all related to the same API call.
43f15e05	2018-09-25T16:17:10	render: opengles renderer actually works now. :)
b2db99cb	2018-09-25T10:41:25	render: First shot at converting opengles renderer to new interfaces.
ef347048	2018-09-24T16:41:55	Fixed bug 4264 - SDL_CreateTextureFromSurface generates error message but returns ok Anthony @ POW Games SDL_CreateTextureFromSurface makes an internal call to SDL_GetColorKey which can return an error and spams the error log with "Surface doesn't have a colorkey" even though the original function didn't return an error.
c01da217	2018-09-24T12:30:47	render: get rid of the predeclared functions in the GL and Metal renderers. (others to come as I continue to update render backends!)
051d1cfc	2018-09-24T02:08:34	render: Make opengl backend take advantage of new high-level features.
8ac5c00a	2018-09-24T02:07:35	render: Add command queue debug logging.
2241b33f	2018-09-23T23:22:56	render: Update Metal and GL backends to use new high-level features, etc. Now nothing is uploaded as dynamic data with Metal's setVertexBytes, etc; it's all in the one big vertex buffer, now.
cc56de44	2018-09-23T23:20:40	render: A bunch of high-level improvements. - high-level filters out duplicate render commands from the queue so backends don't have to. - Setting draw color is now a render command, so backends can put color information into the vertex buffer to upload with everything else instead of setting it with slower dynamic data later. - backends can request that they always batch, even for legacy programs, since the lowlevel API can deal with it (Metal, and eventually Vulkan and such...) - high-level makes sure the queue has at least one setdrawcolor and setviewport command before any draw calls, so the backends don't ever have to manage cases where this hasn't been explicitly set yet. - backends allocating vertex buffer space can specify alignment, and the high-level will keep track of gaps in the buffer between the last used positions and the aligned data that can be used for later allocations (Metal and such need to specify some constant data on 256 byte boundaries, but we don't want to waste all that space we had to skip to meet alignment requirements).
8955fb9b	2018-09-20T16:40:04	render: First shot at moving metal backend over to new batching system.
55cb9966	2018-09-20T16:36:54	render: first shot at reworking opengl backend for new batching system.
5fb67f9f	2018-09-20T15:46:02	render: Move to a batching system for rendering (work in progress).
a2f7af9a	2018-09-09T15:09:38	gles2: Make render command queue dynamic. It now uses a growable linked list that keeps a pool of allocated items for reuse, and reallocs the vertex array as necessary. Testsprite2 can scale to 20,000 (or more!) draws now without drama.
0d327529	2018-09-08T18:26:11	gles2: Major renderer optimization. Work in progress! This moves all the rendering to a command list that is flushed to the GL as necessary, making most common activities upload a single vertex buffer per frame and dramatically reducing state changes. In pathological cases, like Emscripten running on iOS's Safari, performance can go from a dozen draw calls killing your performance to 1000 draw calls running smoothly. This is work in progress, and not ready to ship. Among other things, it has a hardcoded array that isn't checked for overflow. But the basic idea is sound!
264b81b4	2018-09-06T00:56:13	metal: Make sure layer drawableSize is adjusted on resize. Fixes Bugzilla #4250.
3634e563	2018-09-01T20:47:12	metal: SDL_UpdateYUVTexture shouldn't swap planes based on format.
90a5607d	2018-08-29T20:23:42	Fixed compiler warning and use higher precision in angle calculation
92396f7d	2018-08-28T16:19:31	Fixed Windows build
87bc1fb5	2018-08-28T12:57:51	GLES2: Get sin/cos out of vertex shader The only place angle is activated and causes effect is RenderCopyEx. All other methods which use vertex shader, leave angle disabled and cause useless sin/cos calculation in shader. To get around shader's interface is changed to a vector that contains results of sin and cos. To behave properly when disabled, cos value is set with offset -1.0 making 0.0 default when deactivated. As nice side effect it simplifies GLES2_UpdateVertexBuffer: All attributes are vectors now. Additional background: * On RaspberryPi it gives a performace win for operations. Tested with [1] numbers go down for 5-10% (not easy to estimate due to huge variation). * SDL_RenderCopyEx was tested with [2] * It works around left rotated display caused by low accuracy sin implemetation in RaspberryPi/VC4 [3] [1] https://github.com/schnitzeltony/sdl2box [2] https://github.com/schnitzeltony/sdl2rendercopyex [3] https://github.com/anholt/mesa/issues/110 Signed-off-by: Andreas M?ller <schnitzeltony@gmail.com>

fe032ff4	2018-05-10T08:25:23	do the direct3d tap dance for overscan hint only if SDL_VIDEO_RENDER_D3D == 1
eb14b635	2018-05-07T19:52:25	Fixed bug 4134 - Render targets lose scale quality after minimizing a fullscreen window Olli-Samuli Lehmus If one creates a window with the SDL_WINDOW_FULLSCREEN_DESKTOP flag, and creates a render target with SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "linear"), and afterwards sets SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "nearest"), after minimizing the window, the scale quality hint is lost on the render target. Textures however do keep their interpolation modes.

cc56de44

2018-09-23T23:20:40

render: A bunch of high-level improvements. - high-level filters out duplicate render commands from the queue so backends don't have to. - Setting draw color is now a render command, so backends can put color information into the vertex buffer to upload with everything else instead of setting it with slower dynamic data later. - backends can request that they always batch, even for legacy programs, since the lowlevel API can deal with it (Metal, and eventually Vulkan and such...) - high-level makes sure the queue has at least one setdrawcolor and setviewport command before any draw calls, so the backends don't ever have to manage cases where this hasn't been explicitly set yet. - backends allocating vertex buffer space can specify alignment, and the high-level will keep track of gaps in the buffer between the last used positions and the aligned data that can be used for later allocations (Metal and such need to specify some constant data on 256 byte boundaries, but we don't want to waste all that space we had to skip to meet alignment requirements).

gles2: Make render command queue dynamic. It now uses a growable linked list that keeps a pool of allocated items for reuse, and reallocs the vertex array as necessary. Testsprite2 can scale to 20,000 (or more!) draws now without drama.

0d327529

2018-09-08T18:26:11

gles2: Major renderer optimization. Work in progress! This moves all the rendering to a command list that is flushed to the GL as necessary, making most common activities upload a single vertex buffer per frame and dramatically reducing state changes. In pathological cases, like Emscripten running on iOS's Safari, performance can go from a dozen draw calls killing your performance to 1000 draw calls running smoothly. This is work in progress, and not ready to ship. Among other things, it has a hardcoded array that isn't checked for overflow. But the basic idea is sound!

GLES2: Get sin/cos out of vertex shader The only place angle is activated and causes effect is RenderCopyEx. All other methods which use vertex shader, leave angle disabled and cause useless sin/cos calculation in shader. To get around shader's interface is changed to a vector that contains results of sin and cos. To behave properly when disabled, cos value is set with offset -1.0 making 0.0 default when deactivated. As nice side effect it simplifies GLES2_UpdateVertexBuffer: All attributes are vectors now. Additional background: * On RaspberryPi it gives a performace win for operations. Tested with [1] numbers go down for 5-10% (not easy to estimate due to huge variation). * SDL_RenderCopyEx was tested with [2] * It works around left rotated display caused by low accuracy sin implemetation in RaspberryPi/VC4 [3] [1] https://github.com/schnitzeltony/sdl2box [2] https://github.com/schnitzeltony/sdl2rendercopyex [3] https://github.com/anholt/mesa/issues/110 Signed-off-by: Andreas M?ller <schnitzeltony@gmail.com>
