How to set the visual field control parameters of VRay camera? Setting method of visual field control parameters of VRay camera

VRay is a renderer that combines ray tracing and radiosity. Provide high-quality picture and animation rendering, which is convenient for users to render various pictures. It is an indispensable rendering tool for designers and is widely used in material making, lighting and rendering in interior design. There are also many friends who want to learn VRay. In order to help more friends learn the use of VRay renderer quickly, the tutorial "VRay5.0 Realistic Rendering Tutorial from Basic Entry to Extreme Speed Promotion" was launched to help everyone learn VRay renderer quickly.

Setting method of visual field control parameters of VRay camera

This paper illustrates the cost parameters of the physical camera through a case. Let's look at the target distance here.

We find that this target distance cannot be changed, so under what circumstances can we change it when we uncheck this target?

We can set its value here, and usually we check it here.

So let's see what this target distance means. Let's take F as the front view first.

F3 makes it appear in the wireframe. Let's see where the target point is.

The target distance mentioned here actually refers to the distance between the camera and the target point, which is very simple and easy to understand.

Let's enter the camera view in C, and F3 entity display. Let's look at the vertical tilt here.

When we slide on the internet,

You will find that this picture is rotated vertically. When our mouse goes up, it gets closer and farther from above. If we mouse down, it gets closer and closer to the bottom and farther and farther away from the top.

In other words, the smaller the value, the closer the lower part is to us and the farther the upper part is from us. The greater the value, and vice versa. Let's set this value to 0, or use f to enter the front view. Let's carefully study what kind of change it is. Now let's increase this value.

You will find that the target point does not move with the horizontal line of the camera, but the focal plane is inclined in the vertical direction. From this direction, we can see that the phenomenon we just saw is affected by the tilt of the focal plane, so we set it to 0.

Now we also enter the camera view F3 to display the entity. Let's look at the horizontal tilt.

Horizontal tilt is very simple, and it is also a rotation in the horizontal direction, that is, sometimes we can change the visual range by tilting in the horizontal and vertical directions in order to get the desired visual field accurately. Here we set it to 0, which is easy to understand here.

Similarly, this means that the tilt of the focal plane leads to the tilt in the horizontal or vertical direction, so there is an automatic guess of the vertical tilt below. Let's not talk about this. First, put the following two,

One is to guess the vertical tilt, and the other is to guess the horizontal tilt. By understanding these two, we can understand the others. We drag the vertical tilt up, and the same is true after rendering.

In our opinion, if we want this angle, but the perspective relationship is not correct, how can we change it to the correct perspective and get the desired effect? We can click here.

After clicking, it guesses the vertical tilt, which is not what we had before, but the angle we want, and we can make it correct in the perspective relationship of the vertical direction.

Similarly, it is the same to guess the horizontal tilt.

We can see this cabinet area, now let's click and guess the horizontal tilt.

It is restored, that is, when we check automatically guess vertical tilt, then this guess vertical tilt is not available.

Now we can't move it, including this vertical tilt parameter. Now, no matter how we move horizontally, the special relationship in the vertical direction is correct.

We continue to look down, and the west has a designated focus.

When we check it, we can control the focus manually. We need to use this setting when we make the depth of field effect. After checking, we will check the following focus values.

You can set them, they are used together. Usually we don't check the specified focus unless we want the depth of field effect.

Let's continue to have a look. There is an exposure here.

When we check the aperture coefficient, shutter speed and ISO film speed in the camera after exposure. These exposure control parameters only work, so we usually check them in application.

This is the end of the method for setting the visual field control parameters of VRay camera. I hope the above content can help you. If you have any other questions about using the VRay renderer, you can take a look at these VRay tutorials and click this link:
