Ok, so I'm trying to set up 3d effects for libcaelina in my custom helper library for c++ and I don't really get how I'm supposed to change the viewpoint. We don't have gluLookAt so should I just glOrtho into the new position as in 2d? I guess that because glFrustum is set up in the examples. What is the "eye" separation advised to avoid headaches ? Thanks in advance. One more question: In a mid-complex scene how am I supposed to navigate? Moving the world instead of the viewpoint? Different question but related: Can I use texture pointers from libsfil into libcaelina's texture matrix and expect to see something?
