Detailed Description

4x4 Fixed32 matrix.

This 64 byte matrix contains x,y,z and w 32 bit 16.16 fixed point rows and columns. A set of common functions for simple 4 dimensional math are part of the structure.

It is expected to be 4 byte aligned and use scalar math. The members are hard coded to be "x", "y", "z" and "w" for maximum compatibility

Note: Since this is a structure, there is no constructor or destructor, so assume the data is uninitialized when creating this data type.

Member Function Documentation

◆ Identity()

void BURGER_API Burger::FixedMatrix4D_t::Identity ( void )

Initialize a 4D matrix so that it is inert.

Sets the x.x, y.y, z.z and w.w components to BURGER_FLOAT_TO_FIXED(1.0f), all others to BURGER_FLOAT_TO_FIXED(0.0f)

See also: Zero(void)

◆ Set() [1/2]

void BURGER_API Burger::FixedMatrix4D_t::Set ( const FixedMatrix4D_t * pInput )

Copy a matrix into this one.

Perform a literal memory copy operation

Parameters

pInput Pointer to a valid FixedMatrix4D_t

See also: Set(const Matrix4D_t *)

◆ Set() [2/2]

void BURGER_API Burger::FixedMatrix4D_t::Set ( const Matrix4D_t * pInput )

Convert a floating point matrix into a Fixed32 matrix.

Using round to nearest, convert a matrix using floating point values into one that has Fixed32 values. The destination matrix is assumed to be uninitialized.

Parameters

pInput Pointer to a valid Matrix4D_t

See also: Set(const FixedMatrix4D_t *) or float_to_fixed_round(Fixed32 *,float)

◆ SetScale() [1/2]

void BURGER_API Burger::FixedMatrix4D_t::SetScale	(	Fixed32	fX,
		Fixed32	fY,
		Fixed32	fZ )

Create a 4D scale matrix.

Sets the x.x, y.y and z.z components to the input values, w.w is set to BURGER_FLOAT_TO_FIXED(1.0f) and all others are set to BURGER_FLOAT_TO_FIXED(0.0f)
