In this talk, Marek Bielawski, Audio Programmer at CD PROJEKT RED, describes the programmer's journey to generate, stream, and utilize an acoustics graph in a big open-world game—from bad ideas to fair solutions, showing the challenges such as generation times, resource disk space, streaming time and runtime memory usage.
The talk describes the pipeline from voxelizing the entire world, picking the nodes, connecting them and preserving the edge connections, packing resources to serialize, representing the nodes and connections at runtime and also performing and interpreting the pathfinding to fine tune the believability of sound occlusion, and AI perception. It consists of some tricks to efficiently implement a large scale graph, and some dead ends the author stepped into along the way.
Attendees will gain insight and tips on how to approach a large open-world generation subject—learning the challenges in generating a 3D graph and some advised approaches to tackle them. Also, attendees will gain the knowledge of how occlusion works in their favorite Cyberpunk game.
This is for programmers—especially those interested in audio—but also engine and generalists. Basic programming knowledge like cache policies, data containers, or basic algorithms should be enough to digest the talk.
