e8278d0d5b metal renderer: use vertex attributes instead of indexing into a buffer with the vertex id in the shader. Allows for more flexibility with vertex setup in the future. 
Also optimize vertex buffer binding slightly.

55a46abf0a metal renderer: more closely match buffer data alignment requirements from the metal specification. 2019-08-17 01:09:30 -03:00

e5acccc7c3 metal renderer: use the device address space instead of the constant address space for colors. 
It doesn't negatively impact GPU performance in my tests, and it removes the need for 256 byte memory alignment of color data on macOS.

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

638d624f5a metal: Don't try to create a zero-byte vertex buffer.

c01da21756 render: get rid of the predeclared functions in the GL and Metal renderers.

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.

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).

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
