Renderbuffers Web從移動設備為 CPU 和 GPU 共享內存這一事實中獲利的唯一方法是使用GrphicBuffer 。 但由於 Android 限制對私有原生庫 包括 gralloc 的訪問，因此無法再使用它。 問題 有沒有其他方法可以直接訪問紋理的像素數據 我知道，使用 PBO 像素緩沖區對象 可以完成類似的操作。
WebOverview Extension EXT_buffer_storage introduced immutable storage buffers to OpenGL ES. This extension allows the data store for an immutable buffer to be sourced from an external EGLClientBuffer, allowing sharing of EGL client buffers across APIs, across processes, and across different processing cores such as the GPU, CPU, and DSP. WebOpenGL 3.0 introduced a deprecation mechanism to simplify future revisions of the API. Certain features, marked as deprecated, could be completely disabled by requesting a forward-compatible context from the windowing system. OpenGL 3.0 features could still be accessed alongside these deprecated features, however, by requesting a full context.
