GLKMatrix4MultiplyVector3Array(_:_:_:)
Multiplies a 4x4 matrix by an array of 3-component vectors.
Declaration
func GLKMatrix4MultiplyVector3Array(_ matrix: GLKMatrix4, _ vectors: UnsafeMutablePointer<GLKVector3>, _ vectorCount: Int)Parameters
- matrix:
The matrix multiplicand.
- vectors:
On entry, an array of input vectors. On return, an array of output vectors.
- vectorCount:
The number of vectors in the array.
Discussion
The input vectors are treated as they were 4-component vectors with a w-component of 0.0.
