Instead of calling a GL procedure to pass each individual vertex attribute, you can use glVertexAttribPointer to prespecify separate arrays of vertices, normals, and colors and use them to construct a sequence of primitives with a single call to. For a good perspective and look at the scene, use a projection matrix (frustum) with a smaller field of view: glFrustum (-1, 1, -1, 1, 1, 12); Alternatively you can define the frustum by gluPerspective and set the field of view angle in degrees: gluPerspective (90, 1, 1, 12); The view matrix defines the position and viewing direction of.

For best result, use a cubemap. This limit is at least 64, and it depends on the implementation. The commands saved in the display list are executed in order, just as if they were called without using a display list. The speed difference is incredible: It takes well. glWindowPos directly updates the x x and y y coordinates of the current raster position with the values specified. Well the rendering context is active, or I wouldn't be able to do jack, right? I had used "hRC=wglCreateContext(hDC)" to get the handle to the rendering context and a few lines later "wglMakeCurrent(hDC,hRC)" to activate it.
