Fix collision multithreading inconsistency

Multithreading makes collisions be detected in different orders, causing the clustering step of collision resolution to generate possibly slightly different results on each run. This commit makes collision order consistent.
Fix mistake in collision indexing

-# Disallow short functions on one line; break them up.
-AllowShortBlocksOnASingleLine: false
-
-# These two settings trigger stacking of parameters in most cases; this is
-# easier to read and also makes diffs easier to read (since an added or removed
-# parameter is obvious). For example, function calls will look like this:
-#
-#   like_this_long_name(parameter_one,
-#                       parameter_two,
-#                       parameter_three,

-   * release:       Complete build with all options enabled including CUDA and Optix, matching the releases on blender.org
-   * headless:      Build without an interface (renderfarm or server automation).
-   * cycles:        Build Cycles standalone only, without Blender.
-   * bpy:           Build as a python module which can be loaded from python directly.
-   * developer:     Enable faster builds, error checking and tests, recommended for developers.
-   * ninja:         Use ninja build tool for faster builds.
-   * ccache:        Use ccache for faster rebuilds.
-
-   Note: when passing in multiple targets their order is not important.
-   So for a fast build you can for e.g. run 'make lite ccache ninja'.
-   Note: passing the argument 'BUILD_DIR=path' when calling make will override the default build dir.
-   Note: passing the argument 'BUILD_CMAKE_ARGS=args' lets you add cmake arguments.
-
-Other Convenience Targets
-   Provided for other building operations.
-
-   * config:        Run cmake configuration tool to set build options.
-   * deps:          Build library dependencies (intended only for platform maintainers).
-
-                    The existence of locally build dependencies overrides the pre-built dependencies from subversion.
-                    These must be manually removed from '../lib/' to go back to using the pre-compiled libraries.
-
-Project Files
-   Generate project files for development environments.
-
-   * project_qtcreator:     QtCreator Project Files.
-   * project_netbeans:      NetBeans Project Files.
-   * project_eclipse:       Eclipse CDT4 Project Files.
-
-Package Targets
-
-   * package_archive:   Build an archive package.
-
-Testing Targets
-   Not associated with building Blender.
-
-   * test:
-     Run automated tests with ctest.
-
-Static Source Code Checking
-   Not associated with building Blender.
-
-   * check_cppcheck:        Run blender source through cppcheck (C & C++).
-   * check_clang_array:     Run blender source through clang array checking script (C & C++).
-   * check_deprecated:      Check if there is any deprecated code to remove.
-   * check_splint:          Run blenders source through splint (C only).
-   * check_sparse:          Run blenders source through sparse (C only).
-   * check_smatch:          Run blenders source through smatch (C only).
-   * check_descriptions:    Check for duplicate/invalid descriptions.
-   * check_licenses:        Check license headers follow the SPDX license specification,
-                            using one of the accepted licenses in 'doc/license/SPDX-license-identifiers.txt'
-                            Append with 'SHOW_HEADERS=1' to show all unique headers
-                            which can be useful for spotting license irregularities.
-   * check_cmake:           Runs our own cmake file checker which detects errors in the cmake file list definitions.
-   * check_pep8:            Checks all Python script are pep8 which are tagged to use the stricter formatting.
-   * check_mypy:            Checks all Python scripts using mypy,
-                            see: source/tools/check_source/check_mypy_config.py scripts which are included.
-
-Spell Checkers
-   This runs the spell checker from the developer tools repositor.
-
-   * check_spelling_c:      Check for spelling errors (C/C++ only),
-   * check_spelling_osl:    Check for spelling errors (OSL only).
-   * check_spelling_py:     Check for spelling errors (Python only).
-
-   Note: an additional word-list is maintained at: 'source/tools/check_source/check_spelling_c_config.py'
-
-   Note: that spell checkers can take a 'CHECK_SPELLING_CACHE' filepath argument,
-   so re-running does not need to re-check unchanged files.
-
-   Example:
-      make check_spelling_c CHECK_SPELLING_CACHE=../spelling_cache.data
-
-Utilities
-   Not associated with building Blender.
-
-   * icons:

 #
 # This is a build system used by platform maintainers to build library dependencies on
-# Windows, macOS and Linux.
+# Windows and macOS. There is some support for Linux as well, but not ready for releases.
 #
-# For users building Blender, we recommend using the precompiled libraries from lib/ on
-# Windows and macOS, and install_deps.sh on Linux.
+# Windows and macOS users should download the precompiled libraries in lib/, Linux users
+# should run install_deps.sh for building dependencies.
 #
 # WINDOWS USAGE:
-#   Don't call this cmake file yourself, use build_deps.cmd
+#   Don't call this cmake file your self, use build_deps.cmd
 #   build_deps 2013 x64 / build_deps 2013 x86
 #   build_deps 2015 x64 / build_deps 2015 x86
 #
 # MAC OS X USAGE:
-#   Install with homebrew: brew install autoconf automake bison cmake libtool pkg-config yasm
-#   Additional requirements for macOS arm64: brew install flex
+#	Install with homebrew: brew install autoconf automake libtool yasm openssl xz
 #   Run "make deps" from main Blender directory
 #
 # LINUX USAGE:
-#   Install compiler cmake autoconf automake libtool yasm tcl
+#   Install compiler, cmake, autoconf, automake, libtool, yasm
 #   Run "make deps" from main Blender directory

Luna Rood	dbb20c3913	Refactor: remove unnecessary re-initialization Cloth was being re-initialized whenever pinning settings were changed. This has been necessary in the past, as pins were only computed during initialization, but ever since animated vertex weight support was added, by having pins recalculate on every step, this re-initialization has become unnecessary.	2017-03-14 02:50:40 -03:00

Luna Rood	0607cd2e15	Replace plNearestPoints with a deticated solution Implement a dedicated collision detection function (was previously relying on Bullet's generic `plNearestPoints`). This function computes all the collision data to be used for response: coordinates, distance, direction vector. This new function has three advantages: * Remove a dependency from cloth simulation (Bullet). * Give more pleasing collision results (this function is tailored specifically for our collision response method). * Much faster computation (not benchmarked extensively, but observed overal simulation time was cut roughly in half with "collision-heavy" simulations).	2017-03-04 00:24:35 -03:00

Luna Rood	bc3b482b9d	Implement separate normal override and single sided collisions This adds single sided collisions without necessarily using normal override, and adds a separate normal override option. (code can do with some cosmetic cleanup) Also removed a printf I had forgotten.	2017-02-01 14:00:13 -02:00
Luna Rood	6f9cddec21	Implement collision impulse based adaptive step size calculation	2017-02-01 04:09:54 -02:00
Luna Rood	1cc8f2d79b	Apply all object collisions simultaneously This makes all multi-object collisions be solved simultaneously, as not to give any of them priority over the others (as in the sequential collision solve that was implemented) Note that self collisions have not been integrated, and are instead solved independently after the object collisions. This is so that they don't have to fight against the object collisions, as those are generally more robust, and might cause issues with the self collisions.	2017-02-01 01:17:00 -02:00

Luna Rood	ade28fe8a2	Optimization: Use inertial solve for pre-collision Instead of doing a full implicit pre-collision solve, do a simple inertial solve (avance using velocities from previous step), this saves time by doing one less solve per step, and also improves resting stability by eliminating the influence of external forces disturbing the mesh in contacting areas. This improves general cloth performance by about 30-40% in relation to the new cloth code, and improves performance by about 3 times in relation to the original cloth code. This also makes collisions more reliable by removing the need for positional interpolation, and thus decreases the number of subframes required for a successful solve.	2017-01-30 03:47:11 -02:00
Luna Rood	115aea5f2f	Optimization: Use static BVH for collision intersection No need to use moving BVH for intersection checking, as in the end collisions are only evaluated at the next state anyway, so can use static BVH to reduce the amount of intersections to check. Moving BVH will only make sense if ccd is implemented.	2017-01-29 20:40:43 -02:00
Luna Rood	5de2fc2679	Use pre-solved locations for col response evaluation	2017-01-29 20:35:46 -02:00
Luna Rood	e735eda393	Bring back impulse scaled repulses It seems I was a bit too optimistic in thinking that just distance based repulses could handle contacts nicely. Turns out impulse scaled repulses really have enough of an influence in making the collision response more effective, that it is worth keeping it for now, even if at the cost of a very slight stability reduction and and a bit of an increase in collision elasticity. I hope to come up with a better solution, and elliminate this, after cluster based impulse pruning is implemented.	2017-01-28 02:40:14 -02:00

Luna Rood	add9835df6	Clean-up some collision data allocation stuff Self collision pointer logic has been simplified and allocations reduced, as it only collides with one object (self). Also, allocation size for all collisions has been reduced to 1/4, because it was allocating extra space for deprecated stuff.	2017-01-20 02:31:04 -02:00

Luna Rood	2d48769a8b	Fix stability issue and further make collisions inelastic The repulse when colliding points are approaching was being scaled incorrectly by the impulse, causing some undesired elasticity in the collision. I imagine this was a workaround to avoid penetrations because the collision responce was being calculated with respect to the incorrect state, but this is no longer necessary now that that has been fixed. (had missed this case in my previous elasticity commit) Other than that, I have bary interpolated the static repulses to avoid a nasty instability issue in some corner cases.	2017-01-18 23:06:33 -02:00
Luna Rood	c8d1bbf31c	Fix collision distance calculation (makes collisions perfectly inelastic) Collision distance was computed with respect to the positions before the pre-collision solve, but should rather be computed with respect to the newly solved positions. This fixes the issue of the collisions being semi-elastic (bouncy), making them pretty much perfectly inelastic. This also improves the effectiveness of the collision response, preventing penetrations even with far less collision steps.	2017-01-17 22:05:25 -02:00

Luna Rood	22f67557d1	Make caching a bit more sane (fixes plasticity issue) This cleans up the cloth caching logic a bit. Now, a simulation step only occurs if the current time is exactly one frame after the last simulated step, thus preventing time gaps and runtime data corruption. Also, now the cloth is only re-initialized if the cache is actually outdated, instead of always being reset when on the first frame. This solves a bug where the cache was freed when moving the time to a point within the cached period. These changes also fix the issue of non-cached runtime simulation state properties (e.g. plasticity) being reset when going to the first frame or retaining a future state when simulating over an existing cache with time gaps.	2017-01-13 20:10:22 -02:00
Luna Rood	63f023111d	Apply collision responce on state before pre-collision solve (breaks selfcol) This uses the pre-collision solve result only to find the collisions and calculate the responce impulses, but rolls back to before the pre-collision solve when it is time to actually apply the responce. This prevents the cloth from undergoing a double solve per time-step, which essentially made colliding clothes move much faster than non-colliding clothes.	2017-01-12 22:41:50 -02:00

Luna Rood	887dfc298d	Refactor/Optimization: Integrate bend springs into struct/shear A bending spring runs along each structural and shearing spring. Taking advantage of that, this integrates the required data for both into the same spring struct instance. This greatly simplifies bending spring generation code, and also reduces the memory usage for spring storage in about 40-50%. This change also fixes minor memory management issues.	2017-01-05 20:48:48 -02:00

Luna Rood	eca3877ac4	Implement structural plasticity (has issues) The issue here is that the rest length factor isn't cached, because the cache only allows you to store a single type of data per cache (I'll try to fix this later), so if you interrupt the simulation midway through, going to the start frame, the plastic deformations will be reset.	2016-12-15 21:10:11 -02:00

Luna Rood	c03db4c501	Code clean-up (remove unnecessary struct members and add comments) Spring forces and jacobians (f, dfdx and dfdv), were unnecessarily being stored in sring struct.
