Hermet Park	bf6a452c09	common: support static scene mode (internal) ... This adds support for a static scene mode, allowing a scene to be treated as a static image. In this mode, partial rendering for the inner drawable components is skipped. This is especially useful for scenes designed to be fully updated as a whole, such as those used in fully dynamic Lottie contents. issue: https://github.com/thorvg/thorvg/issues/1747	2025-06-19 12:44:30 +09:00
Hermet Park	d2f2ec9933	sw_engine: add support for partial rendering ... This implements RenderDirtyRegion. issue: https://github.com/thorvg/thorvg/issues/1747	2025-06-19 12:44:30 +09:00
Hermet Park	7f5f0b0747	renderer: add partial rendering support ... Partial Rendering refers to a rendering technique where only a portion of the scene or screen is updated, rather than redrawing the entire output. It is commonly used as a performance optimization strategy, focusing on redrawing only the regions that have changed, often called dirty regions. This introduces RenderDirtyRegion, which assists in collecting a compact dirty region from render tasks. Each backend can utilize this class to support efficient partial rendering. This is implemented using a Line Sweep and Subdivision Merging O(NlogN). The basic per-frame workflow is as follows: 1. RenderDirtyRegion::prepare() //Call this in Renderer::preRender(). 2. RenderDirtyRegion::add() //Add all dirty paints for the frame before rendering. 3. RenderDirtyRegion::commit() //Generate the partial rendering region list before rendering. 4. RenderDirtyRegion::get() //Retrieve the current dirty region list and use it when drawing paints. 5. RenderDirtyRegion::clear() //Reset the state. also removed the skip() from paint since engines need to capture the drawable object in any case. issue: https://github.com/thorvg/thorvg/issues/1747	2025-06-19 12:44:30 +09:00
Hermet Park	24aba84942	sw_engine: enable render region clipping during rendering ... Implemented support for clipping shapes and images using a render region bounding box at render time. This allows partial drawing of content, laying the groundwork for upcoming partial rendering functionality. for fast access of the drawing region from the linear rle data, we introduced the binary search for begin/end of rle instead of additional y index buffer. There is a reason for not using a y-index buffer: the shapes in the RLE are not single, continuous shapes but multiple shapes scattered across the space. which means that we need a double-associated data structure per shapes for y indexing, and this data preparation wouldn't be cheaper enough than realtime binary search especially animated data. This also helps for current clipping performance by utilizing the introduced fast-clipping region access. issue: https://github.com/thorvg/thorvg/issues/1747	2025-06-19 12:44:30 +09:00
Sergii Liebodkin	2c048f72e8	gl_engine: remove the outdated tesseletion mechanics ... After introducing Triangle Fan-like Triangulation there is no necessary to have heavy and complex tessellator All unused entities are removed	2025-06-19 02:10:50 +09:00
Mira Grudzinska	3426531dd2	sw_engine: fix focal point clamping ... This approach should be introduced in d8ebd8b4f5. Using FLOAT_EPSILON is not sufficient due to numerical precision, since it's later inverted, and its very small value leads to significant errors during inversion.	2025-06-18 22:07:07 +09:00

Hermet Park	a698504714	renderer: rectify the update flag once more ... - image tag is a bit ambuguous for vector type picture - engine doesn't need to take care of the none flag update because renderer filters that case.	2025-06-18 15:49:47 +09:00
Mira Grudzinska	d8ebd8b4f5	sw_engine: clamp focal point to the edge ... If the radial gradient's focal point lies outside the end circle, it's projected onto the edge. A slight inward offset is applied to avoid numerical issues. Note: Focal point support in the sw and wg engines is consistent with the SVG 1.1 standard, whereas the gl engine aligns with the SVG 2.0 standard.	2025-06-18 14:39:02 +09:00
Mira Grudzinska	b8ef2d44d9	avx/neon: remove double increment of the value ... The span was incremented both in the for loop instruction (ARRAY_FOREACH) and inside the loop body. Fixed. @Issue: https://github.com/thorvg/thorvg/issues/3547	2025-06-18 14:39:02 +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.

Mira Grudzinska	27e78095ff	lottie: fix offset with miter join ... One point was skipped during the creation of the offset corner. The error was not visible because the point lies on the line, but it will become apparent if further modifiers are applied to the object (not supported now).	2025-06-13 11:36:22 +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

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
