* Graph + GraphUI: Consolidate Vertex: Drop SVertex and factory, use Vec[234]f ↵Sven Gothel2023-04-185-277/+174
| | | | | | | | | | | instead of float[] and remove unused VectorUtil methods After Matrix4f consolidation and proving same or better performance on non array types, this enhances code readability, simplifies API, reduces bugs and may improve performance. GraphUI: - Have RoundButton as a functional class to make a round or rectangular backdrop, i.e. impl. addShapeToRegion() via reused addRoundShapeToRegion()
* Math: Complete Matrix4f w/ Vec[234]f and adopt it throughout Quaternion, ↵Sven Gothel2023-04-051-11/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | Ray, AABBox, Frustum, Stereo*, ... adding hook to PMVMatrix Motivation was to simplify matrix + vector math usage, ease review and avoid usage bugs. Matrix4f implementation uses dedicated float fields instead of an array. Performance didn't increase much, as JVM >= 11(?) has some optimizations to drop the array bounds check. AMD64 + OpenJDK17 - Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest) - Matrix4f.mul(b) roughly ~3% slower than FloatUtil.multMatrix(a, b, dest) - FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all - Matrix4f.invert(..) roughly ~3% slower than FloatUtil.invertMatrix(..) RaspberryPi 4b aarch64 + OpenJDK17 - Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest) - Matrix4f.mul(b) roughly ~20% slower than FloatUtil.multMatrix(a, b) - FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all - Matrix4f.invert(..) roughly ~4% slower than FloatUtil.invertMatrix(..) Conclusion - Matrix4f.mul(b) needs to be revised (esp for aarch64) - Matrix4f.invert(..) should also not be slower ..

* Graph: Fix Loop.initFromPolyline()'s Winding determination, document Winding ↵Sven Gothel2023-02-171-2/+81
| | | | | | | | | | | | | | | | | | | | | | | rules for OutlineShape and add get/setWinding in Outline Loop.initFromPolyline()'s Winding determination used a 3-point triangle-area method, which is insufficent for complex shapes like serif 'g' or 'æ'. Solved by using the whole area over the Outline shape. Note: Loop.initFromPolyline()'s Winding determination is used to convert the inner shape or holes to CW only. Therefor the outter bondary shapes must be CCW. This details has been documented within OutlineShape, anchor 'windingrules'. Since the conversion of 'CCW -> CW' for inner shapes or holes is covered, a safe user path would be to completely create CCW shapes. However, this has not been hardcoded and is left to the user. Impact: Fixes rendering serif 'g' or 'æ'. The enhanced unit test TestTextRendererNEWT01 produces snapshots for all fonts within FontSet01. While it shows proper rendering of the single Glyphs it exposes another Region/Curve Renderer bug, i.e. sort-of a Region overflow crossing over from the box-end to the start.

| | | | | | | | | | | | | | | | | | | | incl. FXAA2) ; Test exp. LineAA ; Misc Changes - Revise VBAA - Add border to FBO dropping MSAA - This automatically gives AA for edges on FBO boundary - Correcting ceil-diff, use object-diff instead of win-diff (diff := ceil(a)-a, w/ float a) - Reorg shader - using includes to test diff. AA modes: - [poles, wholeedge] * [equalweight, propweight] - fxaa2 - Exp. LineAA (disabled) - Test ROESSLER-2012-OGLES for detected rectangles only - Test boundary line detection See screenshots: <http://jogamp.org/files/screenshots/graphui/20140322/>

* Bug 802: Graph TextRenderer Performance Part-1 (incomplete, rendering artifacts)Sven Gothel2014-02-244-31/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Strategy Change: - Font.Glyph itself holds it's OutlineShape with it's default scaling. Triangulation is done only once per glyph! - A CharSequence produces a Region by translating and scaling each Glyphs's OutlineShape. This removes the need for re-triangulate - see above. See: TextRendererUtil - The indices of re-added Triangles are offset to the new vertices (FIXME, seems not be be accurate yet). - OutlineShape's vertices and triangles are reused if 'clean'. - Simplified code - Reduced copies API Changes: - OutlineShape, Region, ...: See above - Removed TextRenderer, GlyphShape and GlyphString: Redundant - Added TextRendererUtil to produce the Region from CharSequence Result: - Over 600 fps while changing text for each frame. Previously only ~60fps max. TODO: - Region shall not hold the triangles itself, but the indices instead. This will remove the need to swizzle w/ vertices in the Region Renderer impl and easies reusage of OutlineShapes.
