imx6q - Examples of using OpenGL and OpenCL in same app?

Robert_P — Mon, 20 Nov 2017 23:59:21 GMT

Hello,

I'm on an imx6q, and I'm having trouble using OpenGL ES 2.0 and OpenCL 1.1 in the same app.

For example, let's say I have two separate apps: an OpenGL ES 2.0 app, and an OpenCL 1.1 app.

The OpenGL ES 2.0 app is the 01_SimpleTriangle example from the GPU SDK, running on the framebuffer using Makefile.fbdev.

The OpenCL 1.1 app is just a simple example app that performs a calculation on the GPU.

If I run the OpenGL ES 2.0 app by itself, it runs fine. I see the triangle right side up on my display.

Likewise, if I run the OpenCL 1.1 app by itself, it runs fine.

Now I want to combine them. In a render loop, I need a calculation to be done in OpenCL, and then I need to render using OpenGL.

But if I try to combine the two example apps into one app, the triangle gets rendered upside down.

I must be doing something wrong, but I haven't been able to figure out what.

Are there any simple examples of using OpenGL ES 2.0 and OpenCL 1.1 in the same app?

Regards,

Unfortunately there may be some conflicts between CL and GL texture structures.

Sorry for the inconvenience.

Have a great day,
Victor

That is unfortunate. Is there a conflict even if I'm using OpenCL buffer objects, and not using OpenCL image objects?
