![]() 23 How can I make a call to glFrustum() that matches my call to gluPerspective()?.22 What are the pros and cons of using glFrustum() versus gluPerspective()? Why would I want to use one over the other?.21 How do I transform my objects around a fixed coordinate system rather than the object's local coordinate system?.20 How can I draw more than one view of the same scene?.19 What are the pros and cons of using absolute versus relative coordinates?.18 How do I bypass OpenGL matrix transformations and send 2D coordinates directly for rasterization?.17 How do I draw 2D controls over my 3D rendering?.16 How do I transform only one object in my scene or give each object its own transform?.15 How are coordinates transformed? What are the different coordinate spaces?.13 Are OpenGL matrices column-major or row-major?.12 I can't get transformations to work.10 I put my gluLookAt() call on my Projection matrix and now fog, lighting, and texture mapping don't work correctly.9 How do I get a specified point (XYZ) to appear at the center of the scene?.7 How can I automatically calculate a view that displays my entire model? (I know the bounding sphere and up vector.).6 How do I make the camera "orbit" around a point in my scene?.5 Given the current ModelView matrix, how can I determine the object-space location of the camera?.3 Where should my camera go, the ModelView or Projection matrix?.2 How can I move my eye, or camera, in my scene?.
