VMatrix

Creates a new independent copy of the matrix.

Creates a new independent copy of the matrix.

Creates a new rotation matrix from the angle and the optional translation.

Same as AngleMatrix in Source engine.

Creates a new rotation matrix from the quaternion and the optional translation.

Same as QuaternionMatrix in Source engine, works with non-unit quaternions.

Inverts the matrix ( full 4x4 inverse ).

Same as VMatrix:Invert in Garry's Mod, the matrix stays unchanged if it can't be inverted.

Use invertTR for rotation + translation matrices, it is faster and always succeeds.

Inverts the matrix, assuming it only contains rotation and translation ( no scale ).

Same as VMatrix:InvertTR in Garry's Mod, much faster than invert, but the result is wrong for scaled or skewed matrices. The fourth row is reset to 0 0 0 1.

Sets all 16 values of the matrix ( row by row ).

Transforms the point by the matrix ( rotation, scale and translation ), same as matrix * vec3.

The fourth row is ignored ( no perspective divide ).

Transposes the matrix ( swaps rows and columns ).

For pure rotation matrices the transpose is the inverse.

Returns all 16 values of the matrix ( row by row ).

Returns the unpacked Euler angles ( pitch, yaw, roll ) of the matrix in degrees.

Same as MatrixAngles in Source engine, allocation free alternative to getAngles.

Assumes the matrix has no scale, at pitch ±90 ( gimbal lock ) roll is always 0.

Returns the rotation of the matrix as an angle.

Same as VMatrix:GetAngles in Garry's Mod, values are in range [-180, 180].

Calculates the determinant of the matrix.

1 for rotation matrices, 0 for singular ( non-invertible ) matrices, negative if the matrix mirrors.

Returns the value of the matrix at the given row and column.

Same as VMatrix:GetField in Garry's Mod, out of range indices are clamped to [1, 4].

Slower than accessing the fields directly ( matrix.m23 ).

Returns the forward direction of the matrix ( first column ).

Same as VMatrix:GetForward in Garry's Mod, not normalized if the matrix has scale.

Returns the inverse of the matrix ( full 4x4 inverse ).

Same as VMatrix:GetInverse in Garry's Mod.

Returns the inverse of the matrix, assuming it only contains rotation and translation ( no scale ).

Same as VMatrix:GetInverseTR in Garry's Mod.

Returns the left direction of the matrix ( second column ).

Returns the right direction of the matrix ( negated second column ).

Same as VMatrix:GetRight in Garry's Mod.

Returns the scale of the matrix ( lengths of the forward, left and up columns ).

Always positive, mirroring is not detected ( check getDeterminant for that ).

Returns the translation of the matrix ( fourth column ).

Same as VMatrix:GetTranslation in Garry's Mod.

Returns a transposed copy of the matrix.

Returns the up direction of the matrix ( third column ).

Same as VMatrix:GetUp in Garry's Mod.

Sets the matrix to identity ( no rotation, no translation, scale 1 ).

Checks if the matrix is exactly identity.

Checks if the matrix is equal to the given matrix with the given tolerance.

Each of the 16 values is compared separately.

Checks if the matrix is a rotation matrix ( forward, left and up columns are normalized and perpendicular ).

Same as VMatrix:IsRotationMatrix in Garry's Mod, translation is ignored.

Checks if all values of the matrix are exactly zero.

Interpolates the matrix to the target matrix.

Rotation is interpolated with quaternion slerp ( shortest path ), scale, translation and the fourth row linearly.

Multiplies the matrix by another matrix ( self = self * matrix ).

Same as VMatrix:Mul in Garry's Mod, matrix is applied before the current transform.

Multiplies another matrix by the matrix ( self = matrix * self ).

matrix is applied after the current transform.

Rotates the matrix by the given angle in local space ( self = self * R ).

Same as VMatrix:Rotate in Garry's Mod, translation stays unchanged.

Scales the matrix by the given vector in local space ( self = self * S ).

Same as VMatrix:Scale in Garry's Mod, multiplies the forward, left and up columns, translation stays unchanged.

Scales the translation of the matrix by the given number.

Same as VMatrix:ScaleTranslation in Garry's Mod.

Copies the values of another matrix into this matrix.

Sets the rotation of the matrix from the angle, translation and the fourth row stay unchanged.

Same as VMatrix:SetAngles in Garry's Mod, any existing scale is lost.

Sets the value of the matrix at the given row and column.

Same as VMatrix:SetField in Garry's Mod, out of range indices are clamped to [1, 4].

Sets the forward direction of the matrix ( first column ).

Same as VMatrix:SetForward in Garry's Mod.

Sets the left direction of the matrix ( second column ).

Sets the right direction of the matrix ( stored negated in the second column ).

Same as VMatrix:SetRight in Garry's Mod.

Sets the scale of the matrix while preserving the rotation and translation.

Columns with zero length stay zero, since their direction is unknown.

Sets the translation of the matrix ( fourth column ), rotation and scale stay unchanged.

Same as VMatrix:SetTranslation in Garry's Mod.

Sets the up direction of the matrix ( third column ).

Same as VMatrix:SetUp in Garry's Mod.

Returns the rotation of the matrix as a quaternion, scale and translation are ignored.

Transforms the direction by the matrix ( rotation and scale, without translation ).

The result is not normalized if the matrix has scale.

Translates the matrix by the given vector in local space ( self = self * T ).

Same as VMatrix:Translate in Garry's Mod, the offset is rotated and scaled by the matrix, use setTranslation to move in world space.

Sets all values of the matrix to zero.
