2017-08-09Use YXZ convention for Euler angles.Ferenc Arn
As discussed in issues #1479 and #9782, choosing the up axis (which is Y in Godot) as the axis of the last (or first) rotation is helpful in practical use cases. This also aligns Godot's convention with Unity, helping with a smoother transition for people who are used to working with Unity (issue #9905). Internally, both XYZ and YXZ functions are kept, for potential future applications.

for debug builds. Added set_scale, set_rotation_euler, set_rotation_axis_angle. Addresses #2565 directly. 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.

2017-03-23Explicitly documented that Transform.basis is not necessarily an orthogonal ↵Ferenc Arn
matrix. Also added a check that in axis-angle rotations, axis is a normalized vector, and modified the docs accordingly. Fixes #8113.
2017-03-05A Whole New World (clang-format edition)Rémi Verschelde
I can show you the code Pretty, with proper whitespace Tell me, coder, now when did You last write readable code? I can open your eyes Make you see your bad indent Force you to respect the style The core devs agreed upon A whole new world A new fantastic code format A de facto standard With some sugar Enforced with clang-format A whole new world A dazzling style we all dreamed of And when we read it through It's crystal clear That now we're in a whole new world of code
2017-01-16Overloaded basic math funcs (double and float variants). Use real_t rather ↵Ferenc Arn
than float or double in generic functions (core/math) whenever possible. Also inlined some more math functions.

2017-01-08Fix the order in which additional transformations are applied in Matrix3 and ↵Ferenc Arn
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).
2017-01-03Use right handed coordinate system for rotation matrices and quaternions. ↵Ferenc Arn
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.
2017-01-01Welcome in 2017, dear changelog reader!Rémi Verschelde
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer with state-of-the-art rendering techniques tuned to work as low as middle end handheld devices - without compromising with the possibilities given for higher end desktop games of course. Great times ahead for the Godot community and the gamers that will play our games!
