Release 1.4.0

• Adding strongly typed handles
• (Re)adding option to configure workload size
• Adding serialization support for inputs & bake output - useful for sharing bake results
• Bunch of smaller fixes and cleanup

// Serialization
ommResult ommCpuSerialize(ommBaker baker, const ommCpuDeserializedDesc& desc, ommCpuSerializedResult* outResult);
ommResult ommCpuGetSerializedResultDesc(ommCpuSerializedResult result, const ommCpuBlobDesc** desc);
ommResult ommCpuDestroySerializedResult(ommCpuSerializedResult result);

// Deserialization
ommResult ommCpuDeserialize(ommBaker baker, const ommCpuBlobDesc& desc, ommCpuDeserializedResult* outResult);
ommResult ommCpuGetDeserializedDesc(ommCpuDeserializedResult result, const ommCpuDeserializedDesc** desc);
ommResult ommCpuDestroyDeserializedResult(ommCpuDeserializedResult result);

// Some utility
ommResult ommDebugSaveBinaryToDisk(ommBaker baker, const ommCpuBlobDesc& data, const char* path);

Release 1.3.0

• Adding support for configurable alpha cutoff condition for greater flexibility to implement OIT and particle effects

Release 1.2.0

Enhancements in v1.2.0

• Adding optional SDK logging for easier debugging and integration
• Adding support for UNORM16 and FP16 uv formats also for GPU baker
• Removing WORKLOAD_SIZE error code, replacing this functionality with log messages instead for clarity
• Renaming enums and struct members for consistency (non-code breaking)
• Making sure all shader files have the omm_ prefix
• Updating submodules
• Making dispatch indirect stride larger for improved engine combability

Release 1.1.1

• Fix GPU baker out of bounds write
• Fixing Cmake deprecation warnings
• Updating GLM and xxHash

Release 1.1.0

• CPU baker is accelerated using SAT (summed area table)

Release 1.0.1

SDK now uses https://github.com/NVIDIAGameWorks/ShaderMake

Release 1.0.0

1.0.0 release! 🥳

• (GPU Baker) : General memory improvements. Optionally perform a pre-pass to find optimal memory bounds, or explicitly limit the memory usage via maxOmmArrayDataSize.
• (GPU Baker) : Enable embedded SPIRV shaders also on Linux.
• (CPU Baker) : Adding support for UNORM8 texture format, to speed up the baking operation.
• (CPU Baker) : Conservative baking using multiple texture slices. This allows conservative OMM generation for MIP-mapped textures.
• (General) : C-compatible interface for maximal combability.

Release 0.9.2

• Improved memory management for GPU baker

• Pre-Pass support: split baking in two steps to make sure no redundant memory is allocated

• Limit the max amout ommArrayData the baker may use

Release 0.9.1

Minor API refactor. SDK now uses both a C and C++ interface

Release 0.9.0

Initial release of the Opacity Micro-Map SDK
