sub method Null safety
Substract vector
from the vector at index
.
Implementation
void sub(int index, Vector4 vector) {
final i = _vectorIndexToBufferIndex(index);
final storage = vector.storage;
buffer[i + 0] -= storage[0];
buffer[i + 1] -= storage[1];
buffer[i + 2] -= storage[2];
buffer[i + 3] -= storage[3];
}
