3D LUT on NVIDIA GPU
3D LUT Transform is massively used for color grading and toning applications. To solve the task of 3D LUT grading, we have developed corresponding kernels that run on existing GPU hardware from NVIDIA. We have implemented various formats for 3D LUTs and achieved very high performance for color grading.
3DLUT Transform Features
Hardware and software
Performance of 2.5D and 3D LUT Transforms on GPU
Test images: 16-bit RGB, 2432×1366 (2.5K) and 4032×2192 (4K), fast trilinear interpolation
We have designed that software as a part of our GPU image & video processing SDK. Now our customers have opportunity to use fast 3D LUT transforms on NVIDIA GPU in their realtime color grading applications.
