Hi,

I am a beginner and and developing landscapes with OpenCL. I am hoping someone can direct me to suitable traning material. There are a lot of videos on creating landscapes but very little on OpenCL. A search of the Tutorial Lbrary turns up 11 videos, each of which is a specialised topic. It would be possible to view all of these and not find answers to the specific questions I have.

Thanks
Cliff

I followed a tutorial which built some OpenCL code and included parameters in the bindings. Whenever the parameter values changed, the code automatically re-executed with the new values.

I was able to copy the code and got it working. But when I change a value, it does not update unless I first click in the view pane.

Even worse, once I wrap it as a HDA, it updates only for the first parameter change. After that I have close the project and reopen it to make another value change.

I assume there is a field somewhere to trigger atomatic re-execution Can someone guide me?

Thanks
Cliff

Hi,

I wish to manipulate a pair of heightfields in OpenCL. I can pass them as volumes in the bindings but am forced to link the parameter for each to "height" in the heightfield. I am able to reference the first in my code, but how do I reference the second?

I have also tried passing them through a merge so both reach the OpenCL as a single input. Again I am stuck as to how to reference the second in my code.

Thanks
Cliff
