Webdefine some characteristics of the OpenGL drawing context. The parameter specifies features that you would like the OpenGL context to have. The features are represented by constants that are OR'ed together in the parameter. GLUT_DEPTHsays that a depth buffer should be created; without it, the depth test won't work.

OpenGL (Open Graphics Library) is a cross-platform, hardware-accelerated, language-independent, industrial standard API for producing 3D (including 2D) graphics. Modern computers have dedicated GPU (Graphics Processing Unit) with its own memory to speed up graphics rendering. OpenGL is the software interface to graphics hardware.

WebgluLookAt 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. When a typical projection matrix is used, the center of the scene therefore maps to the center of the viewport.
WebgluLookAt is just a helper function, it provides a way to conviniently generate a view matrix that corresponds to the specified orientation. Instead of using that you can generate the matrix yourself in a variety of ways. For example you may have an orientation quaternion and a position vector for the camera and create the apropriate transformation pacito the deskWebHow many parameters does Glulookat have? first 3 parameters are camera position next 3 parameters are target position the last 3 parameters represent the rolling of camera.

Since the Y axis and the X axis are vertical, it is also required that the vector (C-U) and U be perpendicular to each other. This must be noted when setting this function parameter.
