OptiX is a specialized Windows tool that provides a simple, recursive and flexible pipeline for accelerating ray tracing algorithms on NVIDIA RTX graphics cards. It is widely used in movie production, video game development and scientific visualization. Please note that a developer account on the official NVIDIA website is required for downloading OptiX.

About ray tracing

This rendering technique simulates the physical behavior of light as it travels through a 3D scene. It allows developers to create photorealistic graphics with complex shadows and reflections. However, ray tracing is computationally expensive and requires a powerful GPU. OptiX is intended for optimizing image processing in various real time applications.

Other NVIDIA development utilities from like NVIDIA PhysX are available for download.

How it works

The program automatically divides the ray tracing operation into a series of programmable stages. Users can implement a wide range of optimization algorithms such as bidirectional path tracing and metropolis light transport.

There is a just in time compiler for generating custom RT kernels for each scene. These elements are automatically optimized for the specific hardware architecture that OptiX is running on.
