We describe WireGL, a system for scalable interactive rendering on a cluster of workstations. WireGL provides the familiar OpenGL API to each node in a cluster, virtualizing multiple graphics accelerators into a sort-first parallel renderer with a parallel interface. We also describe techniques for reassembling an output image from a set of tiles(More)
We present the design and implementation of a real-time, distributed light field camera. Our system allows multiple viewers to navigate virtual cameras in a dynamically changing light field that is captured in real-time. Our light field camera consists of 64 commodity video cameras that are connected to off-the-shelf computers. We employ a distributed(More)
Highly unusual Na(+) complexes with neutral tri- and tetra-amines are isolable in good yield from the reaction of NaBAr(F) with the amine in organic media. Structural characterisation reveals primary Na-N bonding, including an unusual sandwich cation [Na(Me3tacn)2](+), derived from homoleptic N6-coordination via two Me3-tacn ligands, and the distorted(More)
We report on the BVRI multi-band follow-up photometry of the transiting extrasolar planet HD 189733b. We revise the transit parameters and find planetary radius R P = 1.154 ± 0.032R J and inclination i P = 85.79 ± 0.24 •. The new density (∼ 1g cm −3) is significantly higher than the former estimate (∼ 0.75g cm −3); this shows that from the current sample of(More)
Recent research has shown that scalable, high-performance graphics systems may be built from commodity graphics hardware running on clusters. The rendered images are then displayed on nodes directly connected to the local system area network. However, many application scenarios require remote display across low speed networks. In this paper we describe a(More)
A new system for CO2 reduction to methanol has been demonstrated using homogeneous ruthenium catalysts with a range of amine auxiliaries. Modification of this amine has a profound effect on the yield and selectivity of the reaction. A TON of 8900 and TOF of 4500 h-1 is achieved using a [RuCl2(Ph2PCH2CH2NHMe)2] catalyst with a diisopropylamine auxiliary.
[GeCl2(dioxane)] reacts with the neutral aza-macrocyclic ligands L, L = Me3tacn (1,4,7-trimethyl-1,4,7-triazacyclononane), Me4cyclen (1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclododecane) or Me4cyclam (1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) and two mol. equiv. of Me3SiO3SCF3 in thf solution to yield the unusual and hydrolytically very(More)
