2022-01-12BLI: Refactor vector types & functions to use templatesClément 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.

2021-07-18Make it optional to track input->output mapping in delaunay_2d_calc.Howard Trickey
Some uses of delaunay_2d_calc don't need to know the original verts, edges, and faces that correspond to output elements. This change adds a "need_ids" value to the CDT input spec, default true, which tracks the input ids only when true. The python api mathutils.geometry.delaunay_2d_cdt gets an optional final bool argument that is the value of need_ids. If the argument is not supplied, it is true by default, so this won't break old uses of the API. On a sample text test, not tracking ids save about 30% of the runtime. For most inputs the difference will not be so dramatic: it only really kicks in if there are a lot of holes.
2021-06-21Delaunay add support for detecting and removing holes from output.Howard Trickey
Adds two new output modes to the CDT api which detect and remove holes. A hole is a face from which a ray shot to the outside intersects an even number of constraint edges, except we don't count constraint edges in the same connected region of faces, where a region is connected via non-constraint edges. These modes are useful for filling in outlines meant to represent text characters and the like. Original patch was from Erik Abrahamsson, modified by me to work with the "valid Bmesh" output type too. I also added tests for the new modes.

2020-08-28Merge newboolean branch into master.Howard Trickey
This is for design task T67744, Boolean Redesign. It adds a choice of solver to the Boolean modifier and the Intersect (Boolean) and Intersect (Knife) tools. The 'Fast' choice is the current Bmesh boolean. The new 'Exact' choice is a more advanced algorithm that supports overlapping geometry and uses more robust calculations, but is slower than the Fast choice. The default with this commit is set to 'Exact'. We can decide before the 2.91 release whether or not this is the right choice, but this choice now will get us more testing and feedback on the new code.

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

2020-02-29Made BLI_delaunay_2d_cdt_calc better at tiny feature elimination.Howard Trickey
The 'random' unit tests and some examples from the new boolean code triggered asserts and crashes. This fixes those. There is a new flag in the input that optionally disables a pass over input to snap segment edges to other segments.
