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.

2017-04-06Added various functions basic math classes. Also enabled math checks only ↵Ferenc Arn
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.
2017-03-05A 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
2017-02-14Revert "Make nan==nan true for GDScript"Juan Linietsky
2017-02-14Make nan==nan true for GDScriptHein-Pieter van Braam
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
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.

2017-01-03Use 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!
