Projections Projections are the important topic of the Computer Graphics. Moreover, It is the Important subject of the Computer Science & Technological field. Once world-coordinate descriptions of the objects in a scene are converted to viewing coordinates, we can project the three-dimensional objects onto the two-dimensional view plane. The process of converting three-dimensional coordinates into […]

## Coordinate Axes Rotations – Computer Graphics

Rotation Rotations are the important topic of the Computer Graphics. Moreover, It is the Important subject of the Computer Science & Technological field. For 3D rotation, we need to pick an axis to rotate about. The most common choices are the X-axis, the Y-axis, and the Z-axis Coordinate-Axes Rotation Z-Axis Rotation Two dimension rotation equations […]

## Knot Vectors – Uniform, Open Uniform and Non-Uniform

Classification of Knot Vectors Knot Vectors is the important topic of the Computer Graphics. Moreover, It is the Important subject of the Computer Science & Technological field. Uniform Periodic B-Spline When the spacing between knot values is constant, the resulting curve is called a uniform B-Spline. For example {0.0,0.1,0.2,… ,1.0} or {0,1,2,3,4,5,6,7} Uniform B-Spline have […]
