Function: perspectiveZO()

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

Generates a perspective projection matrix suitable for WebGPU with the given bounds. The near/far clip planes correspond to a normalized device coordinate Z range of [0, 1], which matches WebGPU/Vulkan/DirectX/Metal’s clip volume. Passing null/undefined/no value for far will generate infinite projection matrix.

Parameters

• fovy: number

Vertical field of view in degrees

• aspect: number

Aspect ratio. typically viewport width/height

• near: number

Near bound of the frustum

• far: null | number

Far bound of the frustum, can be null or Infinity
