Added an euler angle constructor for Basis in GDScript and also exposed is_normalized for vectors and quaternions. Various other changes mostly cosmetic in nature.

| | | | | | | | | | | | | | | | PCG32 doesn't like small seeds, which leads to zero random values (prior to #7532, zero values were handled as special cases). Use a large default seed, and also add a shift in Math::randomize. Fixes #8423.

* | Fix polar decomposition in 2D.Ferenc Arn2017-03-291-2/+2
|/ | | | | | | When performing polar decomposition in 2D as B = R.S, where R is rotation (with determinant +1) and S is scaling, use the convention that reflections are absorbed into S through a reflection around y axis. In 3D, this is done by using a reflection along all three axes, but since the dimensionality is even in 2D, one axis needs to be chosen. Fixes Matrix32::get_rotation and Matrix32::get_scale (which weren't properly fixed in #7445).

* Correct hash behavior for floating point numbersHein-Pieter van Braam2017-02-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes HashMap where a key or part of a key is a floating point number. To fix this the following has been done: * HashMap now takes an extra template argument Comparator. This class gets used to compare keys. The default Comperator now works correctly for common types and floating point numbets. * Variant implements ::hash_compare() now. This function implements nan-safe comparison for all types with components that contain floating point numbers. * Variant now has a VariantComparator which uses Variant::hash_compare() safely compare floating point components of variant's types. * The hash functions for floating point numbers will now normalize NaN values so that all floating point numbers that are NaN hash to the same value. C++ module writers that want to use HashMap internally in their modules can now also safeguard against this crash by defining their on Comperator class that safely compares their types. GDScript users, or writers of modules that don't use HashMap internally in their modules don't need to do anything. This fixes #7354 and fixes #6947.

* Make nan==nan true for GDScriptHein-Pieter van Braam2017-02-148-1/+48
| | | | | | | | | | | | | After discussing this with Reduz this seemed like the best way to fix #7354. This will make composite values that contain NaN in the same places as well as the same other values compare as the same. Additionally non-composite values now also compare equal if they are both NaN. This breaks IEEE specifications but this is probably what most users expect. There is a GDScript function check for NaN if the user needs this information. This fixes #7354 and probably also fixes #6947

| | | | | | | | | | | | | | | | | | | | | | | | This is the follow up for the 2D changes mentioned in PR #6865. It fixes various mistakes regarding the order of matrix indices, order of transformation operations, usage of atan2 function and ensures that the sense of rotation is compatible with a left-handed coordinate system with Y-axis pointing down (which flips the sense of rotations along the z-axis). Also replaced float with real_t, and tried to make use of Matrix32 methods rather than accessing its elements directly. Affected code in the Godot code base is also fixed in this commit. The user code using functions involving angles such as atan2, angle_to, get_rotation, set_rotation will need to be updated to conform with the new behavior. Furthermore, the sign of the rotation angles in existing 2D scene files need to be flipped as well.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transform. This is a part of the breaking changes proposed in PR #6865, solving the issue regarding the order of affine transformations described in #2565. This PR also fixes the affected code within Godot codebase. Includes improvements to documentation too. Another change is, Matrix3::get_scale() will now return negative scaling when the determinant of the matrix is negative. The rationale behind this is simple: when performing a polar decomposition on a basis matrix M = R.S, we have to ensure that the determinant of R is +1, such that it is a proper rotation matrix (with no reflections) which can be represented by Euler angles or a quaternion. Also replaced the few instances of float with real_t in Matrix3 and Transform. Furthermore, this PR fixes an issue introduced due to the API breakage in #6865. Namely Matrix3::get_euler() now only works with proper rotation matrices. As a result, the code that wants to get the rotation portion of a transform needs to use Matrix3::get_rotation() introduced in this commit, which complements Matrix3::get_scaled(), providing both parts of the polar decomposition. Finally, it is now possible to construct a rotation matrix from Euler angles using the new constructor Matrix3::Matrix3(const Vector3 &p_euler).

|/ | | | | | | | Also fixes Euler angles (XYZ convention, which is used as default by Blender). Furthermore, functions which expect a rotation matrix will now give an error simply, rather than trying to orthonormalize such matrices. The documentation for such functions has be updated accordingly. This commit breaks code using 3D rotations, and is a part of the breaking changes in 2.1 -> 3.0 transition. The code affected within Godot code base is fixed in this commit.
