Function: perspectiveNO()

perspectiveNO(fovy, aspect, near, far): mat4

Generates a perspective projection matrix with the given bounds. The near/far clip planes correspond to a normalized device coordinate Z range of [-1, 1], which matches WebGL/OpenGL’s clip volume. Passing null/undefined/no value for far will generate infinite projection matrix.

Parameters

Vertical field of view in degrees

• aspect: number

Aspect ratio. typically viewport width/height

• near: number
