Photorealistic rendering means that we put virtual objects in a scene, assign material models to them, and then run a light simulation program to create a beautiful image.

逼真图形渲染即我们把虚拟物体放到场景里，给它分配材料模型，然后运行光仿真程序来创建一个美丽的图像。

虚像 (光学) Virtual image

（重定向自Virtual object）
上：凹透镜所成的虚像。下：凸面镜所成的虚像。图中黑色箭头O为物体，灰色箭头I为虚像，f为镜的焦点，蓝色箭头是光路，蓝色虚线即是其反向延长线。
Top: The formation of a virtual image using a diverging lens. Bottom: The formation of a virtual image using a convex mirror. In both diagrams, f  is the focal point, O  is the object and I  is the image, shown in grey. Solid blue lines indicate light rays. It can be seen that the light rays appear to emanate from the virtual image but do not actually exist at the position of the virtual image. Thus an image cannot be seen by placing a screen at the position of the virtual image.

虚像（英语：virtual image）指物体发出的光线经折射或反射后，如果为发散光线，其反向延长线相交而成的像，例如，平面镜、眼镜所成的像是虚像。

光线到达面镜（如平面镜）时会发生反射，经过透镜（如凸透镜、凹透镜）时会发生折射。折射或反射后，光路改变，人看到折射或反射后的光线，会感觉光线来自其反向延长线交点的位置（如图）。虚像所在的位置并没有实际物体，也没有光线汇聚，故虚像只能在镜中看到，而无法用光屏承接。

In optics, a virtual image is an image formed when the outgoing rays from a point on an object always diverge. The image appears to be located at the point of apparent divergence. Because the rays never really converge, a virtual image cannot be projected onto a screen. In diagrams of optical systems, virtual rays are conventionally represented by dotted lines. Virtual images are located by tracing the real rays that emerge from an optical device (lens, mirror, or some combination) backward to a perceived point of origin.
