Martin Fouilleul faf024a63a [mtl canvas] reorganizing the loop in render kernel to allow different commands 2023-03-22 16:40:43 +01:00
Martin Fouilleul e9ecd9d521 [mtl canvas] Fix artifacts on tiger that was due to epsilon comparison for cubics equation in draw kernel. Removed that (now do <= 0), but then we need to weed out false negatives for solid triangles. So we compute if the triangle is solid in the triangle kernel and store it in the mg_triangle_data struct for now. 2023-03-22 15:02:04 +01:00
Martin Fouilleul b0be21795e [mtl canvas] prevent tiles entirely covered by textured shapes to be treated as solid (as the texture could be non-uniformly transparent) 2023-03-22 12:02:13 +01:00
Martin Fouilleul 26f669f3c1 [mtl canvas] adding a color command for fully covered, solid color tiles. This is not much of an improvement for now because the tile array just got bigger, but maybe we can use the same scheme and compact it into an int 2023-03-22 10:46:56 +01:00
Martin Fouilleul 90b00979ed [mtl canvas] detecting full covered/uncovered tiles 2023-03-22 09:23:22 +01:00
Martin Fouilleul 0d8bc824a2 [mtl canvas] bucket triangles into per-shape tile queues, then gather into tile arrays. This somewhat improves perf for perf_text test and avoids an awful degradation due to sorting in tiger test (tiger now runs at ~20fps, which is still much slower than it could be, but the triangle coverage method we're using just incurs too much cross product computations...) 2023-03-21 10:22:37 +01:00
Martin Fouilleul a4ef58f2d8 [mtl canvas] Tiling per rectangles into per-shape tile queues (linked lists of triangle indices) to avoid sorting 2023-03-20 16:46:12 +01:00
Martin Fouilleul 11113f597c [mtl canvas, exp] try tiling per tile and avoiding sorting pass (worse on simple shapes and text, but degrades slower with complex scenes (eg tiger). Not great though) 2023-03-20 10:08:17 +01:00
Martin Fouilleul 92f4909d63 [mtl canvas] testing the metal canvas rendering the ghostscript tiger, and acknowledging it's painfully slow 2023-03-18 14:35:51 +01:00
Martin Fouilleul 1d36088302 [mtl canvas] render to an intermediate texture and acquire the drawable and blit to it only at the end of all compute passes 2023-03-16 10:25:56 +01:00
Martin Fouilleul f14f397c99 [mtl surface] don't re-acquire drawable if there's already a valid one acquired 2023-03-15 18:51:50 +01:00
Martin Fouilleul bd8e31c535 [mtl canvas] triple buffer vertex/index/shape buffers 2023-03-15 17:48:39 +01:00
Martin Fouilleul 0c74e997ae [mtl surface] fix crash on exit when metal GPU frame capture is enabled. Apparently, if we release resources (on exit) before all GPU work is completed, libMetalCapture crashes on bad access. To work around that, in mg_mtl_surface_destroy(), we enqueue a last (empty) command buffer and call waitUntilCompleted on it, to ensure all previous command buffers are also completed 2023-03-15 13:02:18 +01:00
Martin Fouilleul 5ce53001e2 [canvas, mtl] clear resets command count and stores clear color. Ccanvas' backend begin proc now takes a clearColor parameter and clears final surface to that color before drawing any batch 2023-03-15 11:09:42 +01:00

Martin Fouilleul f2cb96826c [mtl canvas] fix bias computation for clockwise triangles 2023-03-15 10:04:51 +01:00
Martin Fouilleul 5c1a220f1f [mtl canvas] don't reorder point to make clockwise triangles. Instead, store triangle orientation in triangle struct and multiply orientation in raster test 2023-03-14 15:08:39 +01:00
Martin Fouilleul 221fcbeb6b [mtl canvas] store uv transform and color in triangle data (don't pass vertex or shape buffer to draw kernel) 2023-03-14 12:20:39 +01:00

Martin Fouilleul e9d64166a3 [mtl canvas] fixed bug where tiles left and below screen where all bucketed to the first row/column (same as gl version, see 4a8c77f02) 2023-03-13 16:53:12 +01:00
Martin Fouilleul 6da2494c81 [canvas example] fixed movement 2023-03-13 15:53:35 +01:00
Martin Fouilleul 13f025ab21 [mtl canvas] convert triangle rasterization to fixed point 2023-03-13 15:18:18 +01:00
Martin Fouilleul 7c58145524 [mtl surface] Allow setting swap interval to 0. Note however that vsync needs to be turned off at the OS level for that to work smoothly. Otherwise, we get jittery frame rate with stalls when we run off of drawables (I suppose? should investigate some more). 
This can be done with Quart Debugger in Additional Tools for XCode.
