Provide functions and data structures for linear 3d math using plain C.
Required structures:
- 3D vectors (
float3
) - 4D vectors (
float4
) - 4x4 matrices (
float4x4
) - quaternions (
quat
)
Required operations:
- 3D vectors:
- vec + vec
- vec - vec
- scalar * vec
- len(vec)
- norm(vec)
- dot(vec, vec)
- cross(vec, vec)
- 4D vectors:
- vec + vec
- vec - vec
- scalar * vec
- len(vec)
- norm(vec)
- dot(vec, vec)
- 4x4 matrices:
- mat + mat
- mat - mat
- mat * mat
- det(mat)
- mat^(-1)
- mat^T
- float4x4 identity
- mat * float4
- quaternions:
- quat + quat
- quat - quat
- quat^(-1)
- quat * quat
- quat * float3
