PHOTON - V11.1 Release Note

SLAC (Structured Light Automatic Calibration)

  • Introducing NVZ SLAC (imperceptible automatic alignment)
    • Based on years of internal RnD, now allows to automatically align large quantities of projectors without disturbing your audience by projecting subtle patterns that can be imperceptible to most people's eyes.
    • Continuous alignment mode allows to run NVZ SLAC continuously and improve projection alignment over time while your show is running.
  • Improved GFS (super High speed mode)
    • Now working seamlessly with large quantities of cameras/projectors.
    • Entirely optimized on GPU for smooth and quick experience.
    • Calibrate large projection installations in less than 2 seconds per projector.

  • Point Cloud Alignment
    • ICP Improvements: Changes to the number of samples and the inlier distance, it help the algorithm find the best alignment possible.
    • Robustness improvement: Added a new outlier rejection mechanism to make the algorithm more robust when there are many outliers or when one point cloud is a subset of the other.
    • Sampling Methods: Two new model sampling methods based on normals to improve the algorithm's convergence.

UV

  • Adding uv_remap and uv_offset FXs.
    • UV Remap FX allows users to change an object's texture by using a UV pass to replace it with another. On the other hand, the UV Offset FX applies a relative offset to the source coordinates, allowing it to shift by a few texels in its surroundings.
  • UV Preview with Hierarchy rendering.
    • Users can now preview an assembled version of UVs inside a hierarchy of objects. This tool lets users see the UV clusters of each object that makes up a hierarchy rendering and allows them to snap the texture to clusters independently.
