37b1f989ce metal: use a staging texture in SDL_UpdateTexture, to make sure it doesn't stomp texture data being drawn in a previous frame on the GPU. 2018-11-25 22:13:09 -04:00

4a58722b9f metal: SDL_RenderFillRects uses one draw call per 16k rectangles (within the given FillRects call), instead of one draw call per rectangle. Reduces CPU usage when drawing many rectangles. 2018-11-21 23:37:23 -04:00

244b79e194 metal: SDL_RenderReadPixels on macOS synchronizes the render target's texture data if it's managed, before reading from it. 2018-11-04 14:31:56 -04:00

c9fed27289 metal: fix the SDL_RENDERER_PRESENTVSYNC flag not being set on the renderer info on macOS, when vsync is used. 2018-11-04 12:31:02 -04:00

457390fcf8 metal: avoid an extra buffer allocation and GPU data copy in RunCommandQueue, it's not needed. Improves overall performance. 2018-11-01 20:24:21 -03:00

638d624f5a 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.)

c01da21756 render: get rid of the predeclared functions in the GL and Metal renderers. 
(others to come as I continue to update render backends!)

2241b33f55 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.

eb14b635cd 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.

a8c0532c08 metal: Fix pipeline states to use the pixel format of the current render target, instead of a hard-coded format. 2018-01-07 16:57:32 -04:00

9a8683b275 metal: use a private instead of managed buffer for the renderer's non-changing constant data. 
Recommended by Xcode's Metal frame capture analysis.

990ebba55a metal: Implement fast hardware clearing when possible, by deferring the start of a render pass until a clear or draw operation happens. 2018-01-04 19:29:33 -04:00

888198ee31 metal: Misc. improvements. 
- Use a single buffer for various non-changing constants accessed by the GPU, instead of multiple buffers.
- Do the half-pixel offset for points and lines using a transform matrix so we don't need a malloc when rendering.
- Don't add a half-pixel offset for other primitives and textures. This matches D3D and GL render behaviour.
- Remove the half-texel texture coordinate offset since it's not needed now that there's no more half-pixel position offset when rendering a texture.
- Don't try to set texture usage on iOS 8 since it doesn't exist there.

639ea9fdbc metal: Use sampler state objects instead of shader-declared samplers for linear vs nearest filtering. 
This avoids a ton of shader duplication once multiple shaders that use samplers are added (e.g. the currently missing YUV shaders).

e24dc9053b metal: use a projection matrix instead of manually transforming vertices into clip space on the CPU. 2017-12-30 20:32:22 -04:00
Alex Szpakowski
49df65c25a metal: only 4 (instead of 5) vertices are needed to draw rectangles and textures, and only 3 (instead of 5) vertices are needed to cover the screen for the 'full-screen quad' when clearing. 2017-12-30 18:48:07 -04:00
