A framework for capturing indirect impacts in site‐level screening for biodiversity risks
Methods in Ecology and Evolution, EarlyView.Abstract Site‐based industrial operations such as mining, oil and gas extraction and renewable energy development are associated with many direct and indirect impacts on biodiversity. Consideration of the full range of these impacts when selecting a buffer distance to approximate the Area of Influence (AoI) of a project is critical for effective ...

Fused Collapsing for Wide BVH Construction
Computer Graphics Forum, EarlyView.Abstract We propose a novel approach for constructing wide bounding volume hierarchies on the GPU by integrating a simple bottom‐up collapsing procedure within an existing binary bottom‐up BVH builder. Our approach directly constructs a wide BVH without traversing a temporary binary BVH as done by previous approaches and achieves 1.4 – 1.6 × lower ...
