Render Texture

Render Textures are special types of Textures that are created and updated at runtime. To use them, you first create a new Render Texture and designate one of your Cameras to render into it. Then you can use the Render Texture in a Material just like a regular Texture. The Water prefabs in Unity Standard Assets are an example of real-world use of Render Textures for making real-time reflections and refractions.

Свойства

The Render Texture Inspector is different from most Inspectors, but very similar to the Texture Inspector.

The Render Texture Inspector is almost identical to the Texture Inspector

The Render Texture inspector displays the current contents of Render Texture in realtime and can be an invaluable debugging tool for effects that use render textures.

Свойство: Функция:
Size The size of the Render Texture in pixels. Observe that only power-of-two values sizes can be chosen.
Anti-Aliasing The amount of anti-aliasing to be applied. None, two, four or eight samples.
Depth Buffer The type of the depth buffer. None, 16 bit or 24 bit.
Wrap Mode Отвечает за поведение текстуры при тайлинге:
        Repeat Текстура повторят (тайлит) саму себя
        Clamp Края текстуры растягиваются
Filter Mode Отвечает за то, как текстура фильтруется, если её растянуло при 3D трансформациях:
        No Filtering Вблизи текстура становится более пиксельной
        Bilinear Вблизи текстура становится более размытой
        Trilinear Как и Bilinear, но текстура также размывается и на разных мип уровнях
Aniso Level При обзоре текстуры под крутым углом качество текстуры визуально улучшается. Хорошо подходит для текстур полов и земли.

Пример

A very quick way to make a live arena-camera in your game:

  1. Create a new Render Texture asset using Assets >Create >Render Texture.
  2. Create a new Camera using GameObject > Camera.
  3. Assign the Render Texture to the Target Texture of the new Camera.
  4. Создать широкий, высокий и тонкий бокс
  5. Drag the Render Texture onto it to create a Material that uses the render texture.
  6. Enter Play Mode, and observe that the box’s texture is updated in real-time based on the new Camera’s output.
Render Textures are set up as demonstrated above
