Compressonator V3.0 release brings powerful new 3D model features

Compressonator is a set of tools that allows artists and developers to work easily with compressed assets and easily visualize the quality impact of various compression technologies.  It consists of a GUI application, a command line application and an SDK for easy integration into a developer toolchain. Compressonator 3.0 release provides some useful new features that will save developers time, optimize file sizes and improve rendering time and performance. Here are the top new features you’ll find in Compressonator 3.0

Improved Texture Compression

2D textures wrap around 3D objects to create more realistic surfaces in professional applications or skin and clothing for CG characters in games or movies. Compressonator allows users to choose from all major compression formats for their texture files and supports DirectX® 12, Vulkan® and OpenGL®. A new visual Image Diff option in the texture viewer allows you to compare overlaid views of the original and compressed textures and see a data visualization of any loss of detail upon compression (e.g. pixel difference) at any viewing scale.

Mesh Optimization

Most often model files such as OBJ or GLTF contain highly detailed vertices to create higher fidelity 3D objects. The optimizer simplifies these meshes by essentially removing unnecessary vertices that would be virtually undetectable even at 4K resolutions and streamlines them for fast GPU processing. Users can view OBJ files in OpenGL and GLTF with DirectX 12. (Our next update will support viewing GLTF 2.0 files using a choice of OpenGL, Vulkan or DirectX 12).

Mesh Compression

The 3D files can then be further compressed to reduce physical model file sizes with high compression rates, improving rendering time for complex 3D objects.

What’s Next for Compressonator?

We’re already working towards our Compressonator 3.1 release. Some of the features you can look forward to include:

  • Radeon Powered Compression with Compute and Packed Math Libraries for CPU and GPU
  • Expanded support of the popular mobile-based ETC format.
  • Mesh compression will expand to include support of GLTF format files
  • Full support for viewing GLTF models in OpenGL, Vulkan and DirectX 12
  • Unified 3D model and 2D texture SDK interfaces

You can download Compressonator 3.0 from our Github here. Be sure to let us know what kinds of projects you’re using it for and what we can do to improve the experience.
