Ray Origin

射线起源

Defines the starting point of the raytracing in global coordinates. This normally reflects the position of the active render camera.

以全局坐标定义光线追踪的起始点。这通常反映活动呈现相机的位置。

Ray Direction

射线方向

This is the direction vector of the rendered ray. This vector defines the direction from the Ray Origin in which the ray is underway.

这是渲染光线的方向矢量。这个矢量定义了从射线起点到射线起点的方向。

UVW

The UVW coordinates at the point on a surface currently being rendered.

UVW 坐标位于当前渲染的表面上的点。

UVW Delta

The radius measured in UVW coordinates that is used for calculating the RIP/MIP/SAT samples.

以 UVW 坐标测量的半径,用于计算 RIP/MIP/SAT 样本。

Phong Normal

Defines the Normals at the object surface point currently being rendered.

定义当前呈现的对象表面点上的法线。

Time

时间

Defines the current animation time and can be used to control animated effects.

定义当前动画时间并可用于控制动画效果。
