Detailed Description

Add or update a set of geometry from the SpatialAudio module for geometric reflection and diffraction processing. A geometry set is a logical set of vertices, triangles, and acoustic surfaces, which are referenced by the same AkGeometrySetID. The ID (geometrySetID) must be unique and is also chosen by the client in a manner similar to AkGameObjectID's. It is necessary to create at least one geometry instance for each geometry set that is to be used for diffraction and reflection simulation.

The Sound Engine expects geometry data to be added right after the command. Call AK_CommandBuffer_AddGeometry to add geometry data:

AkGeometryParams geoParams; // Initialize with valid triangles, vertices, surfaces...
auto cmd = (AkCmd_SA_SetGeometry*)AK_CommandBuffer_Add(buffer, AkCommand_SA_SetGeometry);
cmd->geometrySetID = myID;
AK_CommandBuffer_AddGeometry(buffer, &geoParams);

This command can fail for the following reasons:

AK_InvalidParameter: geometrySetID is invalid, or missing geometry data after the command
AK_InsufficientMemory: Not enough memory to complete the operation
