#explorable-explanations of #line-drawing from Amit Patel, saying, “I sometimes see people adapting the #Bresenham line drawing algorithm to draw lines on a grid (especially for roguelike games), but I prefer a much simpler algorithms that runs just as fast. I’ll show the algorithms I use.”

#vanlife #video about a Mercedes Sprinter with a 170-inch wheelbase converted into a camper van for offgrid FPS gaming. He’s installed “bump-outs”, bulging the van walls outwards, to make the bed area a little wider. A three-step stairway for his dog leads up to the bed, designed with storage inside it. His air conditioner bulges out of the top. He’s using a pretty standard setup: diesel space heater inside, a “garage” for storage under the bed accessed through the back door (with some mechanicals: electrical, with a 48V side and a 12V side all running on 12V lithium-ion batteries, and plumbing, with a 35-“gallon” freshwater tank and an electric hot water heater), a portable 10-“pound” propane tank for the stove, a Dometic dorm-sized fridge under the bed, 1000W in five rooftop solar panels. The 48V battery bank is 270Ah, so probably about US$1000,
