From 81bb6873f1c0291fecbf6e429ad15ac3db66a4c0 Mon Sep 17 00:00:00 2001 From: Aki Date: Tue, 12 Mar 2024 22:07:03 +0100 Subject: Legal notices updated Rename contrib -> third-party intendes to express the origin and purpose of that part of the code better. I plan to readd contrib/ again but with more in-project things like bash-completions, dev workflow scripts etc. --- third-party/Opcode/Ice/IceMatrix3x3.cpp | 48 +++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 third-party/Opcode/Ice/IceMatrix3x3.cpp (limited to 'third-party/Opcode/Ice/IceMatrix3x3.cpp') diff --git a/third-party/Opcode/Ice/IceMatrix3x3.cpp b/third-party/Opcode/Ice/IceMatrix3x3.cpp new file mode 100644 index 0000000..c856366 --- /dev/null +++ b/third-party/Opcode/Ice/IceMatrix3x3.cpp @@ -0,0 +1,48 @@ +/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +/** + * Contains code for 3x3 matrices. + * \file IceMatrix3x3.cpp + * \author Pierre Terdiman + * \date April, 4, 2000 + */ +/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// + +/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +/** + * 3x3 matrix. + * DirectX-compliant, ie row-column order, ie m[Row][Col]. + * Same as: + * m11 m12 m13 first row. + * m21 m22 m23 second row. + * m31 m32 m33 third row. + * Stored in memory as m11 m12 m13 m21... + * + * Multiplication rules: + * + * [x'y'z'] = [xyz][M] + * + * x' = x*m11 + y*m21 + z*m31 + * y' = x*m12 + y*m22 + z*m32 + * z' = x*m13 + y*m23 + z*m33 + * + * \class Matrix3x3 + * \author Pierre Terdiman + * \version 1.0 + */ +/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// + +/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +// Precompiled Header +#include "StdAfx.h" + +using namespace IceMaths; + +// Cast operator +Matrix3x3::operator Matrix4x4() const +{ + return Matrix4x4( + m[0][0], m[0][1], m[0][2], 0.0f, + m[1][0], m[1][1], m[1][2], 0.0f, + m[2][0], m[2][1], m[2][2], 0.0f, + 0.0f, 0.0f, 0.0f, 1.0f); +} -- cgit v1.1
