Alpha Support - QC 4

I went to the lengths of re-partitioning my drive, making a Leo install and a Snow install. I am currently on 10.6 & no added plugins whatsoever.

Wither the Alpha support for 10.6 ?

Re: Alpha Support - QC 4

QC has never supported Alpha, so we added it via GLTools -- doing so was rather tricky, hence the weird "blackout" bugs in 10.6 with older versions of GLTools.

Re: Alpha Support - QC 4

Thanks for that cwright, I'd been getting so enmeshed with testing out the sometimes precarious support for dynamically generated meshes in 10.6 upwards that I'd quite forgot that QC doesn't & didn't support Alpha.

I'd quite persuaded myself that something was wrong, having taken the measure of removing GL Tools just to get an Apple only testing environment.

Back to installing - and testing for any 3rd party irregularities / clashes regards Meshes / OpenCL performance afterwards.

Re: Alpha Support - QC 4

This is a bit OT, but talking of OpenCL, have you got your head around how inputs and outputs work with OpenCL? I just realised there doesn't seem to be a way of explicitly specifying whether a particular variable in the function definition is an input or an output. Which is confusing, to say the least....

Re: Alpha Support - QC 4

it's not a science, but:

float arrays declared const are inputs. _rd are inputs. _wr are outputs. for individual floats (not arrays) they're inputs (since you can't output a single float)

Any other cases I haven't investigated yet.
