perspective(leftTangent:rightTangent:topTangent:bottomTangent:nearZ:farZ:reverseZ:)

Creates an off-axis perspective projection from explicit frustum tangents.

Declaration

static func perspective(leftTangent: Float, rightTangent: Float, topTangent: Float, bottomTangent: Float, nearZ: Float, farZ: Float, reverseZ: Bool = true) -> LowLevelRenderer.Camera.Projection

Parameters

  • leftTangent:

    The tangent of the left frustum half-angle.

  • rightTangent:

    The tangent of the right frustum half-angle.

  • topTangent:

    The tangent of the top frustum half-angle.

  • bottomTangent:

    The tangent of the bottom frustum half-angle.

  • nearZ:

    The distance to the near clipping plane.

  • farZ:

    The distance to the far clipping plane.

  • reverseZ:

    If true, the depth range is reversed (1 at near, 0 at far). Defaults to true.

Return Value

An off-axis perspective LowLevelRenderer.Camera.Projection.
