I write this demo just to go though some key concepts of computer graphics.The following features are implemented in this demo:1) transform mesh from local space to world space, then to the camera space;2) Do projection to convert 3d triangles to 2d
To fully apply AChartEngine, you also need to check the source code. Only by knowing the operating principles can you draw charts suitable for your program.
Code:
