nbody_opengles - CUDA N-Body Simulation with GLES

Description

This sample demonstrates efficient all-pairs simulation of a gravitational n-body simulation in CUDA. Unlike the OpenGL nbody sample, there is no user interaction.

Key Concepts

Graphics Interop, Data Parallel Algorithms, Physically-Based Simulation
