| Parameter | Description |
|---|---|
| forward | The forward vector to align the center of view with. |
| up | The up vector to point top of view toward. |
float3x3 The float3x3 view rotation matrix or the identity matrix.
Returns a float3x3 view rotation matrix given a forward vector and an up vector. The two input vectors are not assumed to be unit length. If the magnitude of either of the vectors is so extreme that the calculation cannot be carried out reliably or the vectors are collinear, the identity will be returned instead.
