Despite the fact that he’s just had a baby, PV core team member Andy Zupko has been as prolific as ever! First of all he Integrated the Effects branch into Great White, then swiftly followed up with a fog filter, LOD system, and a modifier set.
Without pausing for breath, he reworked his algorithm for dragging objects in 3D (actually very tricky to map a 2D mouse onto a 3D world).
And finally, he’s reworked his impressive shadow casting system, (with only the most minor of help from myself on a gouraud shader glitch). See his blog post for the full explanation.
