Detailed Description
- Author:
- Koray Balci
- Version:
- 1.0 (April 2002) 1.1
- Date:
- April 2002
Class which defines 4x4 matrix and related/necessary mathematical operations.
Matrix data are stored in a one dimensional array in OpenGL format. Check the additional constructor and () operator overload implementation for accessing data as if it is a two dimensional array.
- Note:
- No inlining has been done yet. All the inlines and other optimizations are to be added in a later stage when we have a better understanding of bottlenecks.
