Topic: Programming, Visual Arts

Format: Session

Tutorials: N/A

Vault Recording: Video

Audience Level: Advanced

Learn alternative approaches to emitting particles from game environment elements, characters and various other renderable objects utilizing shaders+compute+textures to drive and animate particle emission for GPU-based particle systems.

Details on how particle emitting surfaces+shaders can transfer material attributes and other properties to various spawned particle types (transparent, emissive, mesh) will be discussed.

This talk will also discuss technical implementation details and examples, various optimizations, and workflow approaches.

Takeaway

Learn alternative approaches to emitting particles from game environment elements, characters and various other renderable objects utilizing shaders+compute+textures to drive and animate particle emission for GPU-based particle systems.

Intended Audience

The target audience for this talk is graphics programmers and technical artists working with visual effects and shaders.
The audience is expected to be familiar with lower level details of the rendering pipeline such as compute and various shader stages.
