OptiX Ray Tracing Engine
GPU-optimised Optix ray tracing application framework. A simple, recursive, and flexible pipeline accelerates ray tracing techniques. NVIDIA GPUs can power Optix ray tracing applications with programmable intersection, ray creation, and shading.
Ray Tracking
Programmable GPU-accelerated Ray-Tracing Pipeline, C++ single-ray shader model, and RT Cores acceleration.
Scalability
Optimised for present and future NVIDIA GPU generations. Transparently expands multiple GPUs and combines GPU memory using NVLink for huge scenes.
Easy Integration
Free commercially. Debug OptiX application profiling with Nsight Compute 2019. and NsightVSE 2019.
Shader Execution Reordering
Performance optimisation SER improves ray and memory coherency in Optix ray tracing shaders.
Accelerated AI Denoiser
AI-Accelerated Denoiser reduced rendering iterations by denoising images in OptiX. The NVIDIA study “Interactive Reconstruction of Monte Carlo Image Sequences using a Recurrent Denoising Autoencoder” inspired this denoiser. GPU-accelerated artificial intelligence speeds up rendering a high-fidelity, noise-free image.
Flexible, Powerful Ray Tracing with NVIDIA OptiX 8
Photorealism in computer graphics is a long-term objective. You may use Optix ray tracing using NVIDIA OptiX, a powerful and flexible framework. GPU-accelerated ray-casting API NVIDIA OptiX uses CUDA parallel programming. It provides all the tools needed to define and perform complicated ray tracing algorithms on NVIDIA GPUs. When used with OpenGL or DirectX, NVIDIA OptiX lets you construct a renderer for faster, cheaper product development.
Media and entertainment industries like product design and visualisation use NVIDIA OptiX. It lets designers produce high-quality product images and animations to better visualise and iterate designs. Simulating realistic lighting and materials improves product depiction.

NVIDIA OptiX is used in movies and animation for realistic rendering. It allows artists create beautiful visual effects, simulate complex lighting, and achieve cinematic realism.
This update supports Shader Execution Reordering. The performance optimisation SER reorders Optix ray tracing workloads for thread and memory coherency. Sorting rays ensures cohesive execution, minimising divergence. This optimisation reduces rendering workload execution and data divergence. Key NVIDIA OptiX features and benefits.
Key Benefits
Here are some NVIDIA OptiX Benefits:
- Programmable shading: Provides a pipeline for fully customisable shading techniques. Global illumination, shadows, reflections, and refractions are possible with this versatility.
- High performance: Optix Ray tracing using NVIDIA GPUs’ massive computing capacity. Hardware acceleration helps NVIDIA OptiX process complicated scenes with many geometric elements, textures, and lights.
- Built-in acceleration structures like bounding volume hierarchies (BVH) and kd-trees optimise ray-object intersection calculations. Acceleration structures simplify ray-object intersection checks, speeding rendering.
- Dynamic scene updates: Allows real-time object, light, and camera placements in interactive apps.
- Built on CUDA, which allows direct GPU hardware access. This integration lets you use CUDA’s low-level memory management, parallel processing, and sophisticated GPU features.
- Speeds up performance, especially with hardware-accelerated motion blur, available only in NVIDIA OptiX.
- Multi-level instancing: Scales projects, especially massive scenes.
- NVIDIA OptiX denoiser supports HDR, temporal, AOV, and upscaling.
- Triangles, curves, and spheres are supported by NVIDIA OptiX primitives. Recently introduced opacity and displacement micromaps (OMMs) increase scene flexibility and complexity.
