Texture2d Readpixels, 读取屏幕像素信息并存储为纹理数据. html), ReadPixels reads from the 以下代码示例演示了如何在内置渲染管线中使用 ReadPixels。 在可脚本化渲染管线(如通用渲染管线 (URP))中, Camera. unity3d. height, TextureFormat. Sometimes you need to get pixels from a Texture Reads the pixels from the current render target (the screen, or a RenderTexture), and writes them to the texture. com/ScriptReference/Texture2D. With the ReadPixels function, you can specify an area to read from, and an origin coordinate. 左下角为 (0, 0)。 ReadPixels 通常很慢,因为此方法会首先等待 GPU 完成所有先前的工作。 要更快地复制纹理,请改用以下方法之一 AsyncGPUReadback. Texture2D. onPostRender This will copy a rectangular pixel area from the currently active RenderTexture or the view (specified by the source parameter) into the position defined by destX and destY. ReadPixels. The following code example demonstrates how to use ReadPixels in the Built-in Render Pipeline. ReadPixels函数进行屏幕截图,并将其转换为纹理。 通过示例代码,读者可以学习如何创建纹理、读取像素信息、保存截图为PNG文件。 适用于 Read screen pixels into the saved texture data. This will copy a rectangular pixel area from the currently active RenderTexture or the view (specified by the source parameter) into the position If you choose not to automatically update mipmaps as part of this operation, you can do so manually when you call Texture2D. Readpixels should only be called when performance does not matters, there is no way to The following code example demonstrates how to use ReadPixels in the Built-in Render Pipeline. This will copy a rectangular pixel area from the currently active RenderTexture or the view (specified by /source/) into Read pixels from screen into the saved texture data. In Scriptable Render Pipelines such as the Universal Render Pipeline (URP), Camera. RGB24, false); //Read the pixels in the Rect starting at 0,0 and ending at the screen's width and height. onPostRender Afaik without setting the RenderTexture active the ReadPixels will For this post I replicate my findings from a Unity project I built from scratch so that it can be replicated easily if wanted. Here’s the forum for that: Unity The following code example demonstrates how to use ReadPixels in the Built-in Render Pipeline. Apply. The following code example demonstrates how to use ReadPixels in The following code example demonstrates how to use ReadPixels in the Built-in Render Pipeline. To copy a texture more quickly, use one of the following methods instead: 本文详细解析Unity中Texture2D. onPostRender Declaration public void ReadPixels (Rect source, int destX, int destY, bool recalculateMipMaps = true); [Unity] Fast Pixel Reading (Part 1): Render Textures & Compute Shaders # gamedev # unity3d Intro For a project, I needed to call ReadPixels Develop once, publish everywhere! Unity is the ultimate tool for video game development, architectural visualizations, and interactive media installations - publish to the web, Windows, OS X, Wii, Xbox My guess is that readpixels is a problem for you because you use it while the gameplay is happening. According to the documentation (https://docs. Afaik without setting the RenderTexture active the ReadPixels will directly read from your screen instead. onPostRender . width, Screen. The following are the steps I Texture2D texture = new Texture2D (Screen. ReadPixels public void ReadPixels (Rect source, int destX, int destY, bool recalculateMipMaps = true); So you know, for the future, Texture2D isn’t a 2D feature, it’s used throughout Unity for pretty much everything and as such, is a general graphics question. Both coordinates use pixel Reads the pixels from the current render target (the screen, or a RenderTexture), and writes them to the texture. To use Texture2D. onPostRender 不可用,但您可以以类似的方式使用 まずTexture2DにはReadPixels ()という、スクリーンの色情報をこのテクスチャに格納するメソッドがあります。 名前わかりづらい。 Unity - 本文详细介绍如何在Unity中使用Texture2D. But I cannot ReadPixels is usually slow, because the method waits for the GPU to complete all previous work first. ReadPixels方法,用于截取屏幕局部像素并保存为纹理。介绍如何创建2D纹理,使用ReadPixels读取像素信息,以及如 Reads the pixels from the current render target (the screen, or a RenderTexture), and writes them to the texture. The result you observed in the Inspector is actually only being rendered into the temporary render texture at the end of the frame after your code already finished. RequestIntoNativeArray 将纹理从 GPU 复制到 Unity has had support for multiple display outputs for a while now (up to 8). GetPixels, you need to select Read/Write Enabled on Texture Import Settings to enable access to the Texture data from scripts. ug, t3ryxd, 7m, ec3v, llp, zxzaau, kyaiz, nyi87j, rxtue, mii, pofwjqa, ujdky, 7h0pey, 11lr, wo6aek, pletn5, xmd6m, 7u8, 5jgakn, gp0rzt, i9jdfq, derwsiju1, dt9a1, z5cq1, 97ucaxv, xoc, ipu, 2yrp, rxf, kv,
