* Bug 1452 - Decouple math functionality to 'com.jogamp.math' to be toolkit ↵Sven Gothel2023-09-201-378/+0
| | | | | | | | | | | | | | | | | | | | 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.

* PMVMatrix rewrite using Matrix4f, providing SyncMatrix4f* for GLUniformData; ↵Sven Gothel2023-04-071-87/+9
| | | | | | | | | | | | | | | | | 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 Gothel2023-04-051-59/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 ..

* Enhance FloatUtil: Merge ProjectFloat features while adding optimized ↵Sven Gothel2014-06-271-1/+1
| | | | | | | | | | | | | | | | | | variations; PMVMatrix: Remove NIO buffer path, use backing-array only and FloatUtil direct. - FloatUtil pptimized variants: - mapObjToWinCoords (gluProject) passing 'P x Mv' for batch operations - mapWinToObjCoords (gluUnProject) passing 'Inv(P x Mv)' for batch operations - mapWinToObjCoords (gluUnProject) passing 'Inv(P x Mv)' and two winz values for two ray picking resulting in two obj positions. (-> mapWinToRay) - PMVMatrix - dropped low performance NIO mode - simply use common backing-array and fixed offsets directly - drop ProjectFloat usage in favor of FloatUtil - reduce number of temporary arrays

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Added final qualifier where possible - Refined API doc - FloatUtil: - Add machine EPSILON - fixed value and runtime computed (real machEps) - incl. isZero(..), isEqual(..) - Add makeRotationAxis(..) - Moved from PMVMatrix for reusage - Add makeRotationEuler(..) - New, not recommended due to Gimbal-Lock - Add copyMatrix[Column|Row](..) - Add more PI variations and trigo-func float mappings - Removed cross and normalize, use VectorUtil! VectorUtil: - Add copyVec* - Add equals and isZero w/ and w/o EPSILON - Add distance[Square] - Add length[Square] PMVMatrix: - Removed 'destroy' method in favor of making most fields 'final'. AffineTransform: - Added AABBox transform - Public multiply
