- Add operators +, -, * and / too all matrix classes
- Add RetrieveScaleSq and GetReciprocalScaled to all matrix classes
- Add unit tests to all matrix classes
- Fix a bug that causes release configuration not to compile.
The behavior of smart pointers was not updated after the changes to raw pointers, in particular with how default JSON Objects were handled. They both now treat an empty JSON Object (a.k.a. the id for default instances) as meaning to create a default instance on the pointer even if the default is a nullptr. To have a nullptr a JSON Null has to be explicitly written.
By setting the initialization flag before the CheckReady() call, the notifications get sent correctly, and no extra asset references remain. This checkin also includes a unit test for the AssetManager that specifically forces this condition to happen and validates that it works correctly.
- Added operator+(Matrix3x4), operator*(float), RetrieveScaleSq and GetReciprocalScaled to Matrix3x4. Used by Cloth CPU Linear Skinning. These operation will be performant as they use SIMD.
- Modified so there are no virtual functions calls at vertex level.
- Caching indices to simplify the loop when applying skinning.
- Caching static variables Matrix3x4 zero and DualQuaternion zero to avoid creating it for every vertex.
- Removing branching to skip joints when the weight is zero, these cases are rarely and this improves performance by removing branching from loops at vertex level.
- Changing skinning influences so it's a continuous block of memory.
- Caching the vector size() if a variable instead of directly using it in a for loop.
The code that adds a $type field for pointers where needed was still assuming that custom serializer were always for primitives, which isn't the case anymore. This changes updates the behavior to allow $type to be added to those as well as long as they use an object. This does now however rely more heavily on earlier checks that the data needs a $type because it otherwise can't tell the difference between a primitive getting a default value (an empty object). In the original code this situation would have resulted in failed serialization though, so it's unlikely to be a problem.
