Узел Image Texture (изображение)

Узел Image Texture.

Used for applying an image as a texture.

Входы

Vector

3D coordinate that’s projected onto the 2D image using the selected Projection method. The node then outputs the color and alpha at this projected point.

This slot is usually connected to an output of the Узел «Текстурные координаты». If left unconnected, the coordinate is taken from the object’s active UV map (with Z = 0).

Свойства

Изображение (image)

Image data-block to use.

Интерполяция (interpolation)

Method to scale images up or down for rendering.

Линейно (linear):

Интерполяция обычного качества.

Кубический (cubic):

Smoother, better quality interpolation. Bump maps should use this for best results.

Ближайшая (closest):

No interpolation (nearest neighbor). Useful for rendering pixel art.

Smart (Умный):

Cycles Only Only for Open Shading Language. Use cubic interpolation when scaling up and linear when scaling down, for better performance and sharpness.

Projection (проекция)

How to project Vector onto the image for arriving at a color.

Плоский (flat):

Place the image in a unit square (stretching from (0, 0, 0) to (1, 1, 0)) and project the Vector vertically onto it. This projection is typically used in combination with UV maps.

Короб:

Place the image on each side of a unit cube (stretching from (0, 0, 0) to (1, 1, 1)) and project the Vector onto this cube, along the axis that’s closest to the mesh normal. This projection is commonly used in architectural models considering these have lots of box-shaped objects.

Смешать

Rather than projecting onto just one side (which creates sharp transitions), project onto multiple sides and blend the results together. The higher the value, the more blending and the smoother the result.

Сфера:

Wrap the image around a sphere with origin (0.5, 0.5, 0.5), and project the Vector from this origin onto this sphere. This projection is, of course, perfect for spherical objects such as planets, and is also useful for organic objects.

Цилиндр:

Wrap the image around a cylinder with base (0.5, 0.5, 0) and height 1, and project the Vector horizontally from the central axis onto this cylinder. This projection is useful for a label on a bottle, for example. However, it’s not suited for the top or bottom side of objects.

Extension (расширение)

How the image is extrapolated if Vector lies outside the regular (0, 0, 0) to (1, 1, 1) bounds:

Повторить:

Repeat the image horizontally and vertically (tiling).

Дополнение (extend):

Extend the image by repeating the pixels on its edges.

Clip:

Обрежет до размеров изображения, а всем внешним пикселям задаст значение прозрачного чёрного цвета.

Зеркало (mirror):

Repeatedly flip the image horizontally and vertically.

Источник (source)

Type of image (Single Image, Movie…). See Настройки изображения.

Кадры (frames)

How many frames of the Movie-type image (video) to play. Past this point, the video will be paused (unless Cyclic is enabled).

If you want to play the whole video, you can click Match Movie Length in the Image Editor’s Sidebar, then copy the Frames from there to the node.

Начальный кадр

Кадр сцены, с которого должно начаться воспроизведение видео.

Смещение (offset)

Количество кадров для смещения видео к более раннему моменту времени. (Иными словами: сколько пропустить кадров в начале видео.)

Подсказка

Blender plays video textures at the scene framerate, not their original framerate, meaning they’ll be faster or slower than intended if these framerates don’t match up. You can put a Driver on the Offset to work around this. Simply type the following into the field, replacing StartFrame, VideoFrameRate and SceneFrameRate by their respective numbers:

#(frame - StartFrame) * (VideoFrameRate - SceneFrameRate) / SceneFrameRate

Цикличный

Начать заново после последнего кадра, чтобы создать непрерывный цикл.

Автоматическое обновление

Update the video texture in the 3D Viewport when moving through the timeline.

Цветовое пространство

The Color Space the image file was saved in. See Image Settings for details.

Альфа (alpha)

How the image uses its Alpha Channel. See Image Settings for details.

Выходы

Цвет (color)

RGB color from image. If the image has transparency, the color is premultiplied if the Alpha output is used, and unpremultiplied (straight) otherwise.

Альфа (alpha)

Альфа-канал из изображения.
