InstantUV has been exclusively licensed to DGG, which will develop the software further under the new name RapidCompact. DGG is a spinoff of Fraunhofer IGD, founded and led by the original creators of InstantUV.

We have just released a new maintenance version of the InstantUV SDK and MOPS CLI, v1.3.2.

This is a maintenance release with a couple of minor changes and bugfixes:

• New flag decimation:recomputeNormals to toggle computation of new normals after decimation
• New parameter unwrapping:uniformTriangleFactor to control scaling of triangles in UV space
• Fixed an issue that occurred in certain cases when re-importing exported OBJs
• Improved handling of mesh boundaries during simplification

If you would like to download MOPS CLI 1.3.2, or if you need an evaluation key, visit this page.

Note: The Linux version will follow the Windows release within the next few days.

We have just released a new maintenance version of the InstantUV SDK and MOPS CLI, v1.3.1.

This is a maintenance release with a couple of minor changes and bugfixes:

• Default unwrapping method in SDK is now also isometric (similar to in CLI)
• Improved unwrapping of input with broken or bad UVs
• Removed superfluous warning (for corrupted data)
• Improved simplification of triangle soups

In addition, the update provides several other smaller fixes and improvements. If you would like to download MOPS CLI 1.3.1, or if you need an evaluation key, visit this page.

We have just released a new minor version of the InstantUV SDK and MOPS CLI, v1.3.

There are three new features in this version:

• First experimental version of glTF import (binary and non-binary, triangle data only, not all maps supported yet)
• New SDK API function transferFromOther (allowing to insert into chart pointer vectors at arbitrary positions)
• New SDK API function makeSingleIndexed (turns multi-indexed data with aribtrary attributes into a single-indexed representation)

We also added two new settings for export, and modified existing defaults in order to optimally support most use cases out-of-the-box:

• Option export:unlitMaterials to use KHR_materials_unlit on glTF export
• Option export:centerModel to center models on export (default: false)
• Default for unwrapping:method changed to isometric (higher quality, but slower for large meshes)
• Defaults for segmentation:chartAngleDeg and segmentation:cutAngleDeg adapted to improve quality and performance for average input

As usual, this release comes with a couple of performance improvements and bugfixes:

• Fixed handling of degenerate topology (primitives with repeating indices)
• Fixed preservation of existing normals for unwrapping with overlap removal
• Charts resulting from overlap removal always have consistent ordering
• Fixed wrong timings for parallelized parts in debug-level log output
• For setting logging:infoLevel, interpreting values higher as 4 always as DEBUG
• Performance tweaks
• Several smaller fixes

In addition, there is now an new tutorial, dedicated to using the –Make_Compact function of MOPS CLI, with a hands-on example on first steps and parameter tweaking.

MOPS CLI 1.3.0 can simply be downloaded and installed as usual, and will, of course, work with all keyfiles valid for 1.x.

InstantUV head Max Limper will talk about 3D asset optimization at RapidTech in Erfurt next week.

If you like, drop by and have a chat with us – the presentation is going to take place on Wednesday, June 6, at 3pm.

We’re always happy to have our friends at CultLab3D, situated within Fraunhofer IGD as well and constantly providing us with great feedback.

Thanks to their in-depth knowledge about 3D scanning and visualization workflows, the creators of CultLab3D have established a robust, high-quality 3D scanning pipeline, which is being used in industry as well as in public institutions.

The new CultLab3D homepage shows a brand-new gallery of scanned 3D models, which have been automatically optimized for the Web using InstantUV technology. Check it out to learn more about their high-end 3D scanning technology, or just to enjoy some of the beautiful 3D models online!

We have just released a new minor version of the InstantUV SDK and MOPS CLI, v1.2.1.

This is a maintenance release with a couple of bugfixes:

• Fixed error case in OBJ exporter that could prevent Unity or Blender import (“nan” entries)
• Fixed baking/inpainting issue (black pixels) for tangent-space normal maps
• Fixed bug for export of displacement maps when using PNG images
• Added removal of degenerate geometry for remove_duplicate_vertices command
• Ensured consistent order of charts resulting from overlap removal
• Fixed time measurements (debug output) for some parallelized parts

MOPS CLI 1.2.1 can simply be downloaded and installed as usual, and will, of course, work with all keyfiles valid for 1.x.

We are proud and happy to announce the general availability of InstantUV 1.2!

There have been a lot of improvements since v1.1.3, including:

• Binary glTF 2.0 (.glb) export, for direct viewing of exported models on facebook, in Microsoft Mixed Reality tools, and on many other platforms
• New HTML5 viewer with improved mobile and touch support
• New UV atlas packing method, leading to much tighter packings
• New unwrapping method “conformal” (potentially better quality than “fastConformal”, but slower)
• New APIs for texture baking and image generation using the InstantUV C++ SDK
• Baking from point clouds
• Adjustable normal generation hard angle
• Customizable prefix for texture filenames
• Improved return codes for MOPS CLI
• Bugfixes

As always, InstantUV 1.2 consists of new releases for our InstantUV C++ SDK and for our command line tool MOPS CLI. If you would like to download MOPS CLI 1.2, or if you need an evaluation key, visit this page.

Our next major release is finally getting in shape!

The first new feature that we would like to announce is a new, highly efficient packing method. Since InstantUV is one of the fastest solutions available on the market, the challenge was to keep the current user experience, while significantly improving the efficiency of the packing algorithm. This challenge is now mostly solved, and we are looking forward to release it very soon as part of InstantUV SDK / MOPS CLI v1.2.

We currently expect to have the official 1.2 release ready by the mid of February.
