 # Speos Changelog 2026 R1

 Last update: 09.03.2026 

## New Features

### Ray Animation

In some cases, full ray traicing contains too much information to understand how light propagates and interects with the different optical interfaces. As of version 2026 R1, new options have been introduced in the Interactive simulation and the Light Expert analysis tool to enable dynamic visualization of the ray tracing evolution within the optical system. Thus, you can animate the progression of each ray based on configurable parameters, helping you observe and analyze ray paths behavior.

    - Added [ExportVolumicResultHoa](./../sim/client-speos-sim.md#static-method) static method to the **Command** API

### Optical Design Exchange: Solid Bodies management

In Ansys Zemax OpticStudio, you can now apply coordinate breaks inside OBJECT to create complex geometries such as prisms or decentered lenses and export these objects to an \*.odx file. In Speos, upon compute of the ODX feature, a new Solid Body is created as child of the ODX feature and a new geometry corresponding to the Solid Body is created in the Structure panel. This geometry is composed of two surfaces with each a different axis system.

Hybrid mode of Light Guide is extremely flexible as prism could be inside or outside main body. To bring more flexibility, The Max prism height manufacturing parameter has been added to the Light Guide definition.
