2022-01-12Revert "BLI: Refactor vector types & functions to use templates"Clément Foucault
Includes unwanted changes This reverts commit 46e049d0ce2bce2f53ddc41a0dbbea2969d00a5d.
2022-01-12BLI: Refactor vector types & functions to use templatesClment Foucault
This patch implements the vector types (i.e:`float2`) by making heavy usage of templating. All vector functions are now outside of the vector classes (inside the `blender::math` namespace) and are not vector size dependent for the most part. In the ongoing effort to make shaders less GL centric, we are aiming to share more code between GLSL and C++ to avoid code duplication. ####Motivations: - We are aiming to share UBO and SSBO structures between GLSL and C++. This means we will use many of the existing vector types and others we currently don't have (uintX, intX). All these variations were asking for many more code duplication. - Deduplicate existing code which is duplicated for each vector size. - We also want to share small functions. Which means that vector functions should be static and not in the class namespace. - Reduce friction to use these types in new projects due to their incompleteness. - The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a bit of a let down. Most clases are incomplete, out of sync with each others with different codestyles, and some functions that should be static are not (i.e: `float3::reflect()`). ####Upsides: - Still support `.x, .y, .z, .w` for readability. - Compact, readable and easilly extendable. - All of the vector functions are available for all the vectors types and can be restricted to certain types. Also template specialization let us define exception for special class (like mpq). - With optimization ON, the compiler unroll the loops and performance is the same. ####Downsides: - Might impact debugability. Though I would arge that the bugs are rarelly caused by the vector class itself (since the operations are quite trivial) but by the type conversions. - Might impact compile time. I did not saw a significant impact since the usage is not really widespread. - Functions needs to be rewritten to support arbitrary vector length. For instance, one can't call `len_squared_v3v3` in `math::length_squared()` and call it a day. - Type cast does not work with the template version of the `math::` vector functions. Meaning you need to manually cast `float *` and `(float *)[3]` to `float3` for the function calls. i.e: `math::distance_squared(float3(nearest.co), positions[i]);` - Some parts might loose in readability: `float3::dot(v1.normalized(), v2.normalized())` becoming `math::dot(math::normalize(v1), math::normalize(v2))` But I propose, when appropriate, to use `using namespace blender::math;` on function local or file scope to increase readability. `dot(normalize(v1), normalize(v2))` ####Consideration: - Include back `.length()` method. It is quite handy and is more C++ oriented. - I considered the GLM library as a candidate for replacement. It felt like too much for what we need and would be difficult to extend / modify to our needs. - I used Macros to reduce code in operators declaration and potential copy paste bugs. This could reduce debugability and could be reverted. - This touches `delaunay_2d.cc` and the intersection code. I would like to know @howardt opinion on the matter. - The `noexcept` on the copy constructor of `mpq(2|3)` is being removed. But according to @JacquesLucke it is not a real problem for now. I would like to give a huge thanks to @JacquesLucke who helped during this and pushed me to reduce the duplication further.

2022-01-12Cleanup: remove redundant const qualifiers for POD typesCampbell Barton
2021-12-09Cleanup: move public doc-strings into headers for 'blenlib'Campbell Barton
- Added space below non doc-string comments to make it clear these aren't comments for the symbols directly below them. - Use doxy sections for some headers. - Minor improvements to doc-strings. Ref T92709
2021-07-15BLI_memarena: support merging memory arenasCampbell Barton
Useful when thread-local storage has it's own memory arena containing data which is kept after the multi-threaded operation has finished.

2020-08-07Code Style: use "#pragma once" in source directoryJacques Lucke
This replaces header include guards with `#pragma once`. A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`), because they are used in other places. This patch has been generated by P1561 followed by `make format`. Differential Revision: https://developer.blender.org/D8466
2020-05-08Cleanup: take includes out of 'extern "C"' blocksJacques Lucke
Surrounding includes with an 'extern "C"' block is not necessary anymore. Also that made it harder to add any C++ code to some headers, or include headers that have "optional" C++ code like `MEM_guardedalloc.h`. I tested compilation on linux and windows (and got help from @LazyDodo). If this still breaks compilation due to some linker error, the header containing the symbol in question is probably missing an 'extern "C"' block.

2019-02-06Cleanup: remove redundant doxygen \file argumentCampbell Barton
Move \ingroup onto same line to be more compact and make it clear the file is in the group.
2019-02-01Cleanup: remove redundant, invalid info from headersCampbell Barton
BF-admins agree to remove header information that isn't useful, to reduce noise. - BEGIN/END license blocks Developers should add non license comments as separate comment blocks. No need for separator text. - Contributors This is often invalid, outdated or misleading especially when splitting files. It's more useful to git-blame to find out who has developed the code. See P901 for script to perform these edits.
2018-06-01Cleanup: trailing whitespace (comment blocks)Campbell Barton
Strip unindented comment blocks - mainly headers to avoid conflicts.

Instead of having ifdef __GNUC__ all over the headers to use special compiler's hints use a special file where all things like this are concentrated. Makes code easier to follow and allows to manage special attributes in more efficient way. Thanks Campbell for review!

2010-04-15Merge various small changes from render branch:Brecht Van Lommel
* Division by zero fix for TNT SVD code. * Sound fix, in case ffmpeg decode fails, don't use the samples. * Fix for incorrect bounds of transformed objects in new raytracing code. * Gave memory arena's a name used for allocations for easier memory usage debugging. * Dupligroup no_draw option was using layers but not restrict view/render setting. (not a bugfix exactly but would do display list context switching while drawing for no reason). * Fix objects instanced on hair particles not giving consistent results when the object is transformed. * New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4, mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4. * mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple arguments. * endjob callback for WM jobs system. * Geometry node uv/color layer now has search list/autocomplete. * Various small buildsystem tweaks, not strictly needed yet in trunk.

*Added vbvh - Just a experimental tree type :) Variable Way BVH - there is no hardcoded number of childs per each Tree Node - idea is to optimize a tree to reduced the expected number of BB tests even after applying SAH (for that an hardcoded n-way is not enough) - for now childs are stored on a linked list

2006-10-24Irregular shadow fix: the MemArena module didn't give callocs, only malloc.Ton Roosendaal
Made nice crashes that way... but not in !@%@$ OSX because it seems to clear memory unwanted. Solve dit with adding API call in MemArena to default to callocs. Also removed malloc() from MemArena, replaced with MEM_mallocN().
2005-03-29 - added mesh_get_derived_renderDaniel Dunbar
- cancelled previous commit to add RE_findTFAce, instead just added a MemArena to render struct... free'd at end of render, can be used to store other data as well - switch rendering to using DerivedMesh API... this is slightly more inefficient now because it is doing some unnecessary copying. Can be fixed by defining a DerivedMesh function to convert the object into a render object (on todo list)
