OpenCL + OpenGL Interoperability for Rust
Creates a Context with OpenGL interoperability enabled. DirectX interop is theoretically possible, but not currently implemented. MacOS & OpenGL ES support is untested, but should work.
Usage
Your preferred OpenGL library should be set up and working.
Add the following to your Cargo.toml
:
= "0.1"
Add the following to your crate root (lib.rs or main.rs):
extern crate ocl_interop;
Then, when you need the context:
// 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 = get_context?;
// Later, after creating an OpenGL buffer...
// Create an OpenCL buffer from an OpenGL buffer:
let cl_buffer = from_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?;
