* VectorUtil: Add experimental isSelfIntersecting1() with O(n*n) complexitySven Göthel2024-02-141-0/+69
| | | | This doesn't bring reliable results for Graph and also is pretty expensive.

| | | | | | | | FloatUtil.EPSILON epsilon and no collinear test commit 5488665474cc7b88577cedfca6416784f0fda3ba Generalize *seg2segIntersection* w/ epsilon and doCollinear caused a big performance hit about 1/3 due to added doCollinear case and manual epsilon adding branches and having the method being longer - probably not 'hotspot'ed.

* Bug 1501: VectorUtil: Deprecate prev line2line intersection tests, adding ↵Sven Göthel2024-02-131-72/+476
| | | | | | | | | | | new impl; Add isConvex*() to determine whether a polyline is convex I had problems using the previous line2line intersection methods in my (and my son's) C++ gfxbox2 project, e.g. freefall01. Hence I found a different solution, also using less operations: <https://jausoft.com/cgit/cs_class/gfxbox2.git/tree/include/pixel/pixel2f.hpp#n660> While adding intersection tests for our Delaunay (Bug 1501) .. I came across this issue again and hence swapped the implementation.

* Bug 1501: Graph Delaunay: Use default winding outer-boundary:=CCW and ↵Sven Göthel2024-02-121-11/+45
| | | | | | | | | | | inner-hole:=CW w/o using winding determination (might be incorrect) This simplifies our code further and it has been validated that our polygon shoelace-algo for area >= 0 ? CCW doesn't produce correct results with all curves. Hence rely on given winding depending on outer-boundary and inner-hole if CDTriangulator2D.FixedWindingRule == true (default and fixed). This also removes the more costly winding shoelace calculus, hence Outline ctor only sets dirtyWinding:=true w/o calculating the winding.

* Bug 1490 - GraphUI Group: Resolve Performance Issues with Shape Mv Transform ↵Sven Göthel2024-01-221-0/+2
| | | | | | | | | | | | | | | | | | | | -> PMVMatrix4f Shape.setTransformMv() is called for each renderer frame and for each shape, involving 6 Matrix4f.mul() and set*() operations. Since mutation of shape's position, rotation or scale is less frequent than rendering one frame (for all shapes), it is more efficient to maintain a local Matrix4f and update it on such single mutations. Rendering then only needs to perform one Matrix4f.mul() operation using this internal matrix. +++ Also changes name from setTransformMv(PMVMatrix4f) to applyMatToMv(PMVMatrix4f), as its name might be misleading.
* Frustum: Revise code and its Plane definition to support Cube->Frustum as ↵Sven Göthel2024-01-193-50/+198
| | | | | | | | | | | | | | | | | | | | | | | | | well as to extract planes for float[] vec4-shader uniforms. commit 1040bed4ecc6f4598ea459f1073a9240583fc3c3 added AABBox -> Cube -> Frustum mapping (incomplete) and requires Frustum.Plane.set(..) by normal and point-on-plane for distance. Frustum.isOutside(Cube) has been added, testing all its 8-points similar to AABBox. Further all 6 Frustum.Plane shall be extracted to Vec4f and float[], the latter to pass the whole float[4*6] as a vec4[6] uniform array to the shader. +++ Constructor, setter and getter have been adjusted accordingly. Most of the loops have been unrolled. +++ Method names to query Frustum, i.e. 'is*Outside(<Type>)' have been reduced to 'isOutside(<Type>)' where <Type> uniquely indenticates the purpose. Hence only 'isSphereOutside()' is left over.

* AABBox: Rename private fields {bl, tr} -> {lo, hi} denoting proper ↵Sven Göthel2024-01-191-137/+137
| | | | | | | | | | | orientation in API doc br, tr wasn't sufficient as in commit d778889f36bd6bee999ceb502c5f0ce265b014bf while working on Frustum, as it doesn't properly reflect axis order not z. Hence going back to 'low' and 'high' semantics, but using same length identifier and emphasizing far (lo) < near (hi) of our model-view coordinate system.

* Bug 1452 - Decouple math functionality to 'com.jogamp.math' to be toolkit ↵Sven Gothel2023-09-2035-0/+14524
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.
