HOOPS Visualize Desktop 2026.5.0
Overview
The 2026.5.0 release introduces significant leaps forward in point cloud handling, security, and rendering stability. This version focuses on expanding format support with E57 integration while hardening the core engine against vulnerabilities and edge-case crashes to ensure applications remain robust and secure.
What’s New in HOOPS Visualize Desktop/Mobile 2026.5.0
Advanced Point Cloud & Volume Workflows
Users now have more ways to handle massive datasets and complex geometric volumes. This update expands data ingestion capabilities and provides safer, more structured ways to interact with cellular data.
- Structured Volume Entities: A new class-based CellArray interface provides a safer and more intuitive developer experience for interacting with cellular volume entities.
- E57 Format Support: Advanced users can now read location, color, and intensity data from the e57 file format into the OOC workflow to enhance existing customer capabilities.
- OOC Implementation Safeguards: Stability in the current Out-of-Core implementation is ensured by preventing the iteration of multi-scans for E57 files.
Security & Core Hardening
Security remains a top priority. Industry-standard vulnerabilities have been proactively addressed and critical dependencies upgraded to keep software and customer data safe.
- Libtiff Vulnerability Resolution: High-severity vulnerabilities (CVEs) are resolved through an upgrade to libtiff version 4.7.1 and the application of critical security patches.
Rendering Stability & Precision
Several edge-case rendering issues have been resolved, particularly regarding large-scale textures and complex clipping regions, ensuring a smooth visual experience regardless of model complexity.
- Large Texture Handling: Crashes when loading very large textures in the OpenGL2 driver are prevented by new size-handling logic in the texture conversion paths.
- Graceful Offscreen Failover: HPS now fails gracefully and returns catchable errors when creating offscreen windows that exceed device limits, solving previous crash issues.
- Clipping Region Stability: Stability during intense navigation is improved by a fix for crashes that occurred when zooming in on models with active clipping regions.
- Text Transform Accuracy: Visual fidelity is maintained by resolving a regression where text borders remained visible when transforms were active, even if edge visibility was disabled.

New Features
- Out of Core (OOC) rendering workflow now reads position, color and intensity from e57 format data. File import is currently limited to the ooc.exe standalone program while development of the file I/O API workflow progresses.
API Changes
New Public Classes and Types
This release introduces a structured, object-oriented way to define volume cells, moving away from raw integer arrays:
HPS::CellElement: A new base class for all volume cell types.HPS::CellArray: A new type defined as a collection of CellElement objects (typically std::vector<CellElement>).Specific Cell Subclasses: New classes were added to represent different geometric cell types, including:
HPS::CellPyramidHPS::CellBoxHPS::CellWedge(and other standard 3D cell types)
API Method Updates
New overloads were also added for inserting and editing volume entities using these new structured types:
- InsertCellularVolume Overload: A new version of this method was added that accepts a CellArray instead of the legacy raw integer array.
- EditCellularVolume Overload: Similarly, editing methods were updated to support the new structured CellElement approach.
Deprecations
- Support for Visual Studio 2019 (toolchain 14.2) and .Net 8 will be discontinued in HOOPS Visualize Desktop 2026.9.0, planned for release in December 2026.
- Support for macOS on Intel architecture will be discontinued starting with release 2026.9.0 in December 2026 due to the end of support in MacOS 27.
- HOOPS Communicator sprocket (HCA) is deprecated and will be removed in HPS 2027.1.0.
