test_renderlines.m - to draw test lines. Calls renderlines(..) to draw a set of lines.
renderlines.m - for drawing lines
The line drawing process is:
1. lines endpoints (homogeneous co-ordinate system) are specified in north east down co-ordinate system. Refer test_renderlines.m. Points are converted to opengl co-ordinate system (-Z forward axis).
2. view matrix, perspective matrix and viewport matrix are computed.
3. Points transformed to clip space and clipping is done with Liang Barsky algorithm
4. clipped lines are drawn using bresenham algorithm.
5. frame buffer is displayed.
