interesting suggestion. this could also be a good idea to let people write convenient interop with another library such as opencv or eigen. For example, in your macro, you could add constructor and cast operators with opencv's cvMat.
from linalg.
note that the * operator can be implemented outside the class.
However, there already is a * operator defined which does componentwise multiplication.
While this * operator is consistent with the HLSL conventions, it can sometimes be a pitfall for those expecting M=A*B to be doing traditional matrix multiplication.
thats why you see mul() for doing typical matrix matrix or matrix vector multiplication and qmul doing quaternion multiplication. One option is to create subclasses for data that will have a specific semantic meaning, such as Transforms, Quaternions, and Planes.
for example:
class Plane : public vec<float,4> { ... };
class Pose : { float3 position; float4 orientation; ... } ; // assuming quat&vec formulation
from linalg.
It's not quite what you asked for, but I've introduced a new customization point in the v3
branch, as of dd95a16.
Conversions between linalg
types and user types can be enabled by specializing linalg::converter<T,U>
. This can be used to allow linalg
types to construct from external types, as well as for linalg
types to declare a conversion operator to external types. This allows for user-defined constructors to be injected into the library in self-contained way, without modifying the definition of linalg
types.
Note that some of the other operations you mentioned, such as mat * mat
and mat * vec
operators, were adopted as breaking changes for v3
already.
