12 Weird, Excellent Twitter Bots Chosen by Twitter’s Best Bot-Makers

That combination of formal restriction and frictionlessness has led… to so many other creative and useful bots out there that don’t get the attention they deserve. So we spoke to some of our favorite bot-makers about their favorite Twitter bots — their own, and made by others in the #botALLY community — to surface some lesser-known projects worth following.

Paul Walker Furious 7 VFX

Unlike the motion-capture work that Weta had done on earlier films, there were no scans of Walker to create a digital double. So the team went through old footage, building a reference library of Walker as Brian O’Conner by using outtakes from “Furious 7” and previous films in the franchise. But those moments had been filmed in one lighting environment and the Weta team “essentially had to relight his performance” digitally for each new scene, said Letteri.

GTA V - Graphics Study

All the visible meshes are drawn one-by-one, but instead of calculating the shading immediately, the draw calls simply output some shading-related information into different buffers called G-Buffer. GTA V uses MRT so each draw call can output to 5 render targets at once. Later, all these buffers are combined to calculate the final shading of each pixel. Hence the name “deferred” in opposition to “forward” for which each draw call calculates the final shading value of a pixel.
