openGL is an API that allows you to send instructions to the graphics card. It allows you to upload textures to VRAM, execute drawing, load and run shaders, and all of that stuff. You could kind. (gluLookAt中“向上”向量背后的直觉很简单:看任何东西。现在将你的头倾斜90度。你所在的位置没有改变,你看的方向没有改变,但你视网膜中的图像明显改变了。. The gluLookAt function creates a viewing matrix derived from an eye point, a reference point indicating the center of the scene, and an up vector. The matrix maps the reference point to the negative z-axis and the eye point to the origin, so that when you use a typical projection matrix, the center of the scene maps to the center of the viewport.

The gluLookAt function provides an easy and intuitive way to set the camera position and orientation. Basically it has three groups of parameters, each one is composed of 3 floating point values. The first three values indicate the camera position. The second set of values defines the point we’re looking at.

Though I can't tell you the exact function names in OpenGL, there are basically two functions you'll have to use: 1.Line function (two calls) - to draw two radial lines shown in your figure 2. Arc function - to draw the circular arc in your figure. Any movement of a camera can be also seen as an opposite movement of the whole world. gluLookAt applied such an opposite transformation on current modelview. So usually.
