用openGL实现三角形，长方形等基本图元的线性变换，-Achieved with openGL triangle, rectangle and other primitives linear transformation

opengl实现图形基于颜色的线性插值变换，还有基于坐标位置，基于顶点坐标的。-opengl achieve linear interpolation based on color graphics transformation, as well as based on the coordinate position, based on the vertex coordinates.

进行矩阵变换使用，包括旋转变换，平移变换，缩放变换(Use of matrix transformation)
