详细描述

Non-astronomical daily solar orbit, matching the reference's manual pitch/yaw mode.

Value-owned immutable configuration. Directions point towards the sun in EVEngine's Y-up coordinates, with Unreal (X,Y,Z) mapped to (X,Z,Y). No clock, weather, renderer, intensity curve or persistence state is owned here. @thread Concurrent evaluation is safe; there are no callbacks or borrowed objects.

成员函数说明

create()

Result< SkySolarOrbit > eve::daynight::SkySolarOrbit::create ( double  pitchDegrees, double  yawDegrees  )

static

Prepare a daily orbit with pitch [-90,90] and yaw [-360,360] degrees.

参数

pitchDegrees	Tilt from an overhead noon sun; reference default is 30.
yawDegrees	Rotation about the vertical axis; reference default is zero.

返回

Owned orbit, or InvalidArgument for nonfinite/out-of-range input.
