perspective


Description:

public void perspective (float fov_y, float aspect, float z_near, float z_far)

Multiplies this by the described perspective matrix

<note>You should be careful not to have to great a z_far / z_near ratio since that will reduce the effectiveness of depth testing since there wont be enough precision to identify the depth of objects near to each other.</note>

Parameters:

this

A 4x4 transformation matrix

fov_y

Vertical field of view angle in degrees.

aspect

The (width over height) aspect ratio for display

z_near

The distance to the near clipping plane (Must be positive, and must not be 0)

z_far

The distance to the far clipping plane (Must be positive)
