獲取 RenderTexture 的幾種方式
阿新 • • 發佈:2018-12-10
RenderTexture Constructor
public class ExampleClass : MonoBehaviour {
public RenderTexture rt;
void Start() {
rt = new RenderTexture(256, 256, 16, RenderTextureFormat.ARGB32);
}
}
RenderTexture.GetTemporary
This function is optimized for when you need a quick RenderTexture to do some temporary calculations.
CommandBuffer.GetTemporaryRT()
Add a “get a temporary render texture” command.
RenderTexture Assets
通過編輯器建立 RT 資原始檔,Assets -> Create -> Render Texture
Camera.OnRenderImage
public class Example : MonoBehaviour { Material material; void OnRenderImage(RenderTexture source, RenderTexture destination) { // Copy the source Render Texture to the destination, // applying the material along the way. Graphics.Blit(source, destination, material); } }
GrabPass
在 Shader 中使用 GrabPass 獲取 RT
GrabPass
{
"_BackgroundTexture"
}
