Matrix4x4

A Matrix is a structure which may describe different transformation. Note: Matrix4x4.init is the identity Matrix.

struct Matrix4x4 {

this(float a, float b, float c, float d, float e, float f, float g, float h, float i);

Matrix4x4 getInverse();

Matrix4x4 loadIdentity();

Matrix4x4 translate(Vector2f vec);

Matrix4x4 rotate(float angle);

Matrix4x4 rotate(float angle, Vector2f center);

Matrix4x4 scale(Vector2f scale);

Matrix4x4 scale(Vector2f scale, Vector2f center);

void lookAt(Vector3f eye, Vector3f look, Vector3f up);

void perspective(float fov, float ratio, float nearp, float farp);

bool ortho(Rect rect, float zNear, float zFar);

inout(float[16]) getValues();

inout(float) opIndex(ubyte index);

Matrix4x4 opBinary(Matrix4x4 mat);

Matrix4x4 opOpAssign(Matrix4x4 math);

bool opEquals(Matrix4x4 mat);

}

Functions

det float det(): Calculate the determinant
getInverse Matrix4x4 getInverse(): Returns the inverse Matrix of the current. If the current matrix has a determinant of approximately zero, the identity Matrix (.init) is returned.
getValues inout(float[16]) getValues(): Returns the 16 values of the Matrix by ref
loadIdentity Matrix4x4 loadIdentity(): Reset the current Matrix to the identity Matrix
lookAt void lookAt(Vector3f eye, Vector3f look, Vector3f up): Calculates a View-Matrix
opBinary Matrix4x4 opBinary(Matrix4x4 mat): Supported operations: only *
opEquals bool opEquals(Matrix4x4 mat): Compares two Matrices approximately
opIndex inout(float) opIndex(ubyte index): Returns a specific value by index
opOpAssign Matrix4x4 opOpAssign(Matrix4x4 math): Supported operations: only *=
ortho bool ortho(Rect rect, float zNear, float zFar): Calculate a prthographic projection
perspective void perspective(float fov, float ratio, float nearp, float farp): Calculate a perspective projection
rotate Matrix4x4 rotate(float angle): Rotate the Matrix about angle (in degree!)
rotate Matrix4x4 rotate(float angle, Vector2f center): Rotate the Matrix about angle (in degree!) about the given center position
scale Matrix4x4 scale(Vector2f scale): Scale the Matrix about factor scale
scale Matrix4x4 scale(Vector2f scale, Vector2f center): Scale the Matrix about factor scale about the given center position
translate Matrix4x4 translate(Vector2f vec): Translate the Matrix
