Hermet Park	0c0c30bd36	renderer: clean up the base render flow ... - Clear out the render update flag to skip any unnecessary update situation. - Consolidate the composition flags update.	2025-06-16 18:00:30 +09:00
Sergii Liebodkin	abfc5cc9e1	wg_engine: avoid forced texture flushes ... After introducing staged buffer removed the need for forced flush of each texture data into gpu General approach used for all data types Can increase performance on discrete GPUs	2025-06-16 10:50:25 +09:00
Hermet Park	39b0f87cb3	api: revise the canvas update() API ... Removed the paint parameter previously used to forcibly update a single paint. This behavior was unsafe in ThorVG, as a single paint object may be connected to others through the scene graph. Now, the canvas engine is responsible for properly updating all damaged paints as needed, allowing the user to simply call update() in any case. API Modifications: C++ API: * Result Canvas::update(Paint* paint) -> Result Canvas::update() CAPI: - tvg_canvas_update_paint() Issue: https://github.com/thorvg/thorvg/issues/3116	2025-06-16 10:43:13 +09:00

Hermet Park	3eaf110e0a	sw_engine: revised the texture clipping ... previous logic doesn't work if the clipping shape has any inner corners. replace the logic with a intermediate composition approach for stability. - performance can be drop at texture clipping by ~11% - size is reduced by -0.5kb issue: https://github.com/thorvg/thorvg/issues/3520	2025-06-11 22:35:54 +09:00
Hermet Park	174fae9089	sw_engine: replaced texture mapping AA with 4x sampling interp ... The old approach often produced incorrect results, especially when the fixed pixel had a noticeably different color from the texture due to the AA target blending position was fixed. Although the previous method worked well as an analytical AA solution with good speed and fair quality, it couldn't overcome the above limitation. The new approach still applies AA only to polygon edges for efficiency. While the quality may be slightly reduced, it offers greater stability. - binary size: -1.1kb - performance diff: ignoreable issue: https://github.com/thorvg/thorvg/issues/1729	2025-06-11 10:09:39 +09:00

Hermet Park	2e5af58592	sw_engine: texture mapping performance optimization ... - Replaced `modff()` with a custom method, boosting texture mapping performance by ~15%. - Unified opacity/non-opacity logic for improved binary size efficiency(-0.5kb). - Implemented minor changes for better cache effectiveness.	2025-06-10 19:38:20 +09:00
Hermet Park	bfef89858f	renderer: increased the reference count capacity ... 255 is enough size in general but a bit limited.	2025-06-10 14:51:19 +09:00
Sungun No	676a465c55	gl_engine: fix always-true clear flag ... The clear flag specified in Canvas::draw is ignored when set to false, since GlRenderer::mClearBuffer is never explicitly reset to false. This commit ensures that mClearBuffer is reset to its default (false) after being used, so that the clear operation behaves correctly per frame. - Issue: #1779	2025-06-09 17:02:56 +09:00
Hermet Park	8eb046c318	sw_engine: skip AA if texture are orthogonally rotated. ... there is no necessary applying AA for 0/90/180/270 degree rotation issue: https://github.com/thorvg/thorvg/issues/3452	2025-06-09 16:07:45 +09:00
