CC crashes when performing certain rasterize operations
Posted: Fri Jan 22, 2016 9:48 pm
I've found that when you:
1. perform a rasterize operation with resample input loud checked (e.g. maximum height on a 0.25m grid) and create a cloud,
2. then rasterize the new cloud again but with an average calculation (e.g. average height on a 1.00m grid), the resample input loud check is disabled but remains checked.
CC will crash if you attempt to make a cloud at this point.
I'm reasonably certain this is the cause and extent of the problem, but I could have missed some combinations. Regardless, I think when resample input loud gets disabled it also needs to be cleared.
On a related topic, I had previously asked about using resample input loud with average, where CC chooses the XY of the point closest to the average Z and creates a new point with the discovered XY and the average Z. I've been able to work around this by pulling my points into Manifold GIS and using a SQL query to create the points I want. I will post the SQL if you want, though it's unlikely to be useful without Manifold and I've now gone a bit further with it to snap those points onto a line. The SQL is also quite long to handle certain degenerate conditions.
