* Graph GLRegion*: Utilize interleaved GLSL buffers for vertices, curveParams ↵Sven Gothel2023-04-203-104/+14
| | | | | | | | | | | and the optional colors (GPU effeciency and performance; Increased CPU buffer growth performance) Besides simplification, interleaved GPU memory boosts - effeciency - performance Since only one underlying backing buffer on the CPU (host) has to be managed, it also increases buffer growth performance.

| | | | | | | | | | | 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()

| | | | | | | | | | | | | | | | | | | | | | | | invPMv null; PMVMatrix: Make Mvi, Mvit optional at ctor, add user PMv and PMvi - used at gluUnProject() .. Matrix4f.mapWin*() variants w/ invPMv don't need temp matrices, they also shall handle null invPMv -> return false to streamline usage w/ PMVMatrix if inversion failed. PMVMatrix adds user space common premultiplies Pmv and Pmvi on demand like Frustum. These are commonly required for e.g. gluUnProject(..)/mapWinToObj(..) and might benefit from caching if stack is maintained and no modification occured. PMVMatrix now has the shader related Mvi and Mvit optional at construction(!), so its backing buffers. This reduces footprint for other use cases. The 2nd temp matrix is also on-demand, to reduce footprint for certain use cases. Removed public access to temporary storage. +++ While these additional matrices are on demand and/or at request @ ctor, general memory footprint is reduced per default and hence deemed acceptable while still having PMVMatrix acting as a core flexible matrix provider.

* PMVMatrix rewrite using Matrix4f, providing SyncMatrix4f* for GLUniformData; ↵Sven Gothel2023-04-072-38/+33
| | | | | | | | | | | | | | | | | Utilize Vec3f, Recti, .. throughout API (Matrix4f, AABBox, .. Graph*) Big Easter Cleanup - Net -214 lines of code, despite new classes. - GLUniformData buffer can be synced w/ underlying data via SyncAction/SyncBuffer, e.g. SyncMatrix4f + SyncMatrices4f - PMVMatrix rewrite using Matrix4f and providing SyncMatrix4f/Matrices4f to sync w/ GLUniformData - Additional SyncMatrix4f16 + SyncMatrices4f16 covering Matrix4f sync w/ GLUniformData w/o PMVMatrix - Utilize Vec3f, Recti, .. throughout API (Matrix4f, AABBox, .. Graph*) - Moved FloatUtil -> Matrix4f, kept a few basic matrix ops for ProjectFloat - Most, if not all, float[] and int[] should have been moved to proper classes - int[] -> Recti for viewport rectangle - Matrix4f and PMVMatrix is covered by math unit tests (as was FloatUtil before) -> save Passed all unit tests on AMD64 GNU/Linux
* Math: Complete Matrix4f w/ Vec[234]f and adopt it throughout Quaternion, ↵Sven Gothel2023-04-053-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 ..

| | | | | | | | | 67a723477ecd818fbc5859fe20ee536a3b4efae5 (reverting and clarifying) All Graph ShaderPrograms used are owned by RegionRenderer, not RenderState nor [GL]Region*, hence [GL]Region* shall only nullify the resources but not destroy the shader currently in use.

* Graph Perf Counter: Use GlueGen's Clock.currentNanos() to ease on ↵Sven Gothel2023-03-071-13/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | performance-hit measuring performance. This was mostly notable on a Raspberry-Pi 4 arm64, where perfromance degragated around 3x using high-freq counter. Using our well determined Clock.currentNanos() removes this overhead, back to 'easy measuring' and having a well defined 'currentNanos()' since module start. TestTextRendererNEWT00 can enable Region and Font perf-counter w/ '-perf', w/o it only uses its own counter and hence reduce the high-freq burden (64% perf win on raspi4). +++ Below numbers show that Region.addOutlineShape() perhaps needs a little performance work to allow long text to be processed in 'real time' on embedded platform. Hower, usually we cache the Region for long text and can have at least one liner to be renderer within 60fps fast, i.e. Region produced in ~26ms for a 81 char line instead of ~130ms for 664 chars. +++ Raspberry Pi 4b, OpenJDK17, Debian 11: Using current medium sized text_1 w/ 664 chars, w/o '-perf' and after having passed 40 frames, we have following durations: - process the OutlineShape -> Region: 129ms (text) - Render the Region: 53ms Startup Times: - loading GlueGen - loading test 0 [ms] - loading GlueGen - start test 1,910 [ms] - loading test - start test 1,910 [ms] - loading test - gl 2,631 [ms] - loading test - graph 2,636 [ms] - loading test - txt 2,844 [ms] - loading test - draw 3,062 [ms] Perf .. 1 / 1: Perf Launch: Total: graph 5, txt 207, draw 218, txt+draw 425 [ms] 1 / 1: Perf Launch: PerLoop: graph 5,505,740, txt 207,530,736, draw 218,393,680, txt+draw 425,924,416 [ns] 20 / 20: Perf Frame20: Total: graph 16, txt 376, draw 281, txt+draw 657 [ms] 20 / 20: Perf Frame20: PerLoop: graph 807,055, txt 18,820,824, draw 14,075,146, txt+draw 32,895,970 [ns] 20 / 40: Perf Frame40: Total: graph 3, txt 129, draw 53, txt+draw 182 [ms] 20 / 40: Perf Frame40: PerLoop: graph 176,670, txt 6,451,330, draw 2,658,217, txt+draw 9,109,547 [ns] +++ On a modern desktop (~2y old), GNU/Linux Debian 11, AMD GPU on Mesa3D: Using current medium sized text_1 w/ 664 chars, w/o '-perf' and after having passed 40 frames, we have following durations: - process the OutlineShape -> Region: 42ms (text) - Render the Region: 5ms Startup Times: - loading GlueGen - loading test 0 [ms] - loading GlueGen - start test 310 [ms] - loading test - start test 309 [ms] - loading test - gl 459 [ms] - loading test - graph 460 [ms] - loading test - txt 490 [ms] - loading test - draw 506 [ms] Perf .. 1 / 1: Perf Launch: Total: graph 1, txt 29, draw 15, txt+draw 45 [ms] 1 / 1: Perf Launch: PerLoop: graph 1,191,096, txt 29,868,436, draw 15,519,445, txt+draw 45,387,881 [ns] 20 / 20: Perf Frame20: Total: graph 240, txt 68, draw 21, txt+draw 89 [ms] 20 / 20: Perf Frame20: PerLoop: graph 12,045,651, txt 3,415,402, draw 1,069,348, txt+draw 4,484,750 [ns] 20 / 40: Perf Frame40: Total: graph 283, txt 42, draw 5, txt+draw 47 [ms] 20 / 40: Perf Frame40: PerLoop: graph 14,152,395, txt 2,116,114, draw 265,292, txt+draw 2,381,406 [ns]

| | | | | | | | | | | | | | | Ease GLArrayData* buffer growth. Using integer indices, i.e. GL_UNSIGNED_INT, requires us to pass a GLProfile 'hint' to the GLRegion ctor. Region.max_indices is computed in this regard and used in Region.addOutlineShape(). TODO: If exceeding max_indices, the code path needs some work. Buffer growth is eased via GLArrayData using its golden growth ratio and manually triggering growth before processing all triangles in Region.addOutlineShape(). +++ TextRegionUtil static drawText() won't clear passed Region anymore, caller has to do this if so intended.

The growthFactor becomes essential for better growth behavior and can be set via setGrowthFactor(). The other changes were merely to clean up the GLArrayData interface and its 4 implementations. Not great to change its API, but one name was misleading ['getComponentCount' -> 'getCompsPerEleme'], so overall .. readability is enhanced. Motivation for this change was the performance analysis and improvement of our Graph Curve Renderer.

Drop erroneous Glyph ID_SPACE, ID_CR to rely on no-shape for 'space' non-contour resolves different cmap-mappings of fonts, not following 'some std'. Hence getGlyph(glyph_id) no more uses the `font.getGlyph(Glyph.ID_UNKNOWN)` shape, but a null-shape as intended and using the hmtx and hhea table values for asvance and bounds. This fixes 'space' spacing in general and specifically FreeSerif-Regular and the like. This path also simplifies processing/layout of glyphs in process(..) and get*BoundsFU(..).
