* Graph Clipping: Initial Region impl of AABBox clipping using GLSL shader ↵Sven Göthel2024-01-093-21/+72
| | | | | | | | | | | | (Convenient using Graph/GraphUI produced AABBox) Simple demo, setting clip-bbox manually: - src/demos/com/jogamp/opengl/demos/graph/ui/UIShapeClippingDemo00.java TODO: - GLSL: Add missing Mv-multiplication of vertex-position -> gcv_ClipBBoxCoord -- AABBox min/max should be set pre-multiplied w/ Mv covering an independent area, not per Shape/Region. -- This to properly work with moving/scaling of each Shape/Region etc
* Graph Clipping: GLSL: Add `USE_AABBOX_CLIPPING`, i.e. clipping via AABBox ↵Sven Göthel2024-01-098-19/+50
| | | | | | | | | | | | | | | min/max vec3 as convenient using Graph/GraphUI produced AABBox USE_AABBOX_CLIPPING - Conditional compilation w/ macro 'USE_AABBOX_CLIPPING' - gcv_ClipBBoxCoord smooth varying setup in vertex shader - fragment shader clips via branch if( is_inside(gcv_ClipBBoxCoord, gcu_ClipBBox[0], gcu_ClipBBox[1]) < 0.5 ) { CLIP } - clipping via discard or alpha=0 in case of buggy-discard. Other optimization: - Drop gcv_ColorTexExt, fragment-shader uses gcu_ColorTexBBox[2] directly (flat) - Simplified gcv_ColorTexCoord smooth varying equation in vertex shader.
* Graph GLSL functions.glsl: Complete overload vec2 and vec3 variants; Fix ↵Sven Göthel2024-01-091-8/+52
| | | | | | | | | | | | | | | | | | 'and'/'or' semantic (swapped); Add EPSILON in clip_coord(..) and add is_inside(..) function Complete overload vec2 and vec3 variants Fix 'and'/'or' semantic (swapped) - 'and' uses multiplication, i.e. all arguments must be > 0 (ideally 1) - 'or' uses addition, i.e. only one arguments must be > 0 (ideally 1) - both uses clamp [0..1] Add EPSILON in clip_coord(..) - Only 'coord > high+EPSILON' is outside Add is_inside(..) function - Similar to clip_coord(..) but returns float 0 or 1 instead of selecting color.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | aspect-ratio, letter-boxed or zoomed (config) + Bug 1466 Fix color mixing Bug 1465: Region currently simply bloats a given texture to its region AABBox, which renders textures with the wrong aspect ratio. Add facility to program the texture-coordinates to either letter-box or scaled-up (and cut) true aspect-ratio. Default shall be zoom (scale-up and cut), but user shall be able to set a flag in the Region for letter-box. Have the shader clip texture coordinates properly, best w/o branching to soothe performance. See functions.glsl +++ Bug 1466: Current color mix: texture * color_channel * color_static is useless in GraphUI. color_static shall modulate the texture, which works. But in case of color_channel (attribute/varying) we want it to be mixed so it can become the more dominant color for e.g. a border. Desired is: color = vec4( mix( tex.rgb * gcu_ColorStatic.rgb, gcv_Color.rgb, gcv_Color.a ), mix( tex.a * gcu_ColorStatic.a, 1, gcv_Color.a) );
* Bug 1463 - Graph Font: Whitespace or undefined Glyphs shall not cover (any) ↵Sven Gothel2023-09-261-4/+7
| | | | | | | | | | | | | | | | | | height exceeding overall CharSequence TypecastFont using `metrics.getAscentFU() - metrics.getDescentFU()` for ascent used for all undefined and whitespace Glyphs w/o a spatial outline, leads to a potential exceeding height compared to the actual used bounding box of the rendered text. This in turn leads to layout issues, e.g. button labels are placed too low. Solution: - Whitespace/Undefined: Drop full height 'metrics.getAscentFU() - metrics.getDescentFU()', b/c of non-existing shape height. - Otherwise, layout on AABBox or created empty shape would pick up such default hhea-table ascent which might exceed actual string height. Sideeffect would be if user relies on height of a whitespace. However, knowing this fact - a user may always pick the hhea-table's ascent metric values as exposed in Font and Font.Metric. This resolves remaining layout issues, including button labels.

* Bug 1452 - Decouple math functionality to 'com.jogamp.math' to be toolkit ↵Sven Gothel2023-09-2013-29/+29
| | | | | | | | | | | | | | | | | | | | agnostic (PMVMatrix, Matrix4f, Vec4f, ..) Math functionality (PMVMatrix, Matrix4f, Vec4f, ..) - shall be used toolkit agnostic, e.g. independent from OpenGL - shall be reused within our upcoming Vulkan implementation - may also move outside of JOGL, i.e. GlueGen or within its own package to be reused for other purposed. The 'com.jogamp.opengl.util.PMVMatrix' currently also used to feed in GLUniformData via the toolkit agnostic SyncAction and SyncBuffer shall also be split to a toolkit agnostic variant. An OpenGL PMVMatrix specialization implementing GLMatrixFunc can still exist, being derived from the toolkit agnostic base implementation. +++ Initial commit .. compile clean, passing most unit tests.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 ..
