Rust的OpenCL + OpenGL互操作性

创建一个启用了OpenGL互操作的上下文。DirectX互操作理论上可行，但尚未实现。MacOS & OpenGL ES支持尚未测试，但应该可以工作。

用法

您首选的OpenGL库应已设置并正常运行。

在您的 Cargo.toml 中添加以下内容

ocl-interop = "0.1"

在您的crate根目录（lib.rs或main.rs）中添加以下内容

extern crate ocl_interop;

当您需要上下文时

// First, create an OpenGL context and make sure it is active...

// Next, Create an OpenCL context with the interop enabled: (NOTE:
// `::get_context` will return the first available GPU device on your that
// supports OpenGL interop on your system -- you may need to choose a device
// and create the context manually instead if this does not work):
let context = ocl_interop::get_context()?;

// Later, after creating an OpenGL buffer...

// Create an OpenCL buffer from an OpenGL buffer:
let cl_buffer = ocl::Buffer::<f32>::from_gl_buffer(&queue, None, gl_buffer)?;

// Acquire the buffer, making it usable:
cl_buffer.cmd().gl_acquire().enq()?;

// Use the buffer...

// Release the acquisition:
cl_buffer.cmd().gl_release().enq()?;
