Returns:

A new matrix.

staticinlineortho(left:FastFloat, right:FastFloat, bottom:FastFloat, top:FastFloat, near:FastFloat, far:FastFloat):Mat4

Create a new orthographic projection matrix.

Parameters:

left

The left of the box.

right

The right of the box.

bottom

The bottom of the box.

top

The top of the box.

near

The depth of the near floor of the box.

far

The depth of the far floor of the box.

Returns:

A new matrix.

staticinlinepersp(fovY:FastFloat, aspect:FastFloat, zn:FastFloat, zf:FastFloat):Mat4

Create a new perspective projection matrix.

Parameters:

fovY

The vertical field of view.

aspect

The aspect ratio.

zn

The depth of the near floor of the frustum.

zf

The depth of the far floor of the frustum.

Returns:

A new matrix.
