HLSL shading language backend
Supported shader model versions:
- 5.0
- 5.1
- 6.0
All matrix construction/deconstruction is row based in HLSL. This means that when
we construct a matrix from column vectors, our matrix will be implicitly transposed.
The inverse transposition happens when we call [0] to get the zeroth column vector.
Because all of our matrices are implicitly transposed, we flip arguments to mul. mat * vec
becomes vec * mat, etc. This acts as the inverse transpose making the results identical.
The only time we don’t get this implicit transposition is when reading matrices from Uniforms/Push Constants.
To deal with this, we add row_major to all declarations of matrices in Uniforms/Push Constants.
Finally because all of our matrices are transposed, if you use mat3x4, it’ll become float4x3 in HLSL.
