void avl::ResizeVector ( const avl::Vector2D& inVector, float inNewLength, avl::Vector2D& outVector )
Parameters
Name | Type | Range | Default | Description | |

inVector | const Vector2D& | ||||
inNewLength | float | 0.0 - | 1.0f | ||
outVector | Vector2D& |
Description
Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when a zero vector is given on input.
