3D Parameter Window - OpenGL - ViewHere you can define your camera position and orientation: You define your own position including the distance, your up-vector, and optionally an object rotation. ChaosPro internally of course uses an absolute coordinate system in order to specify your current position. But for your convenience all settings on this tab use a coordinate system relative to your current position. Now, what does this mean? Of course, better intuitive handling of the settings!
Have a look at the parameter window: You can see the observer position at the bottom of the image: There are three boxes labeled "Viewpoint", "Observer" (read-only) and "top" (read-only). Your position ("Observer") cannot be specified directly, instead you adjust your position intuitively by adjusting the sliders "horizontal", "vertical" and "distance":
Now I told you something about rotating and such, but one thing remains to be mentioned: Rotating around what? The sliders rotate not around an artificial "0" point, no, they rotate around the viewpoint: You specify where you look at, and if you then rotate around horizontally by 45 degree, you rotate around your viewpoint in your own left-right direction by 45 degree. The viewpoint itself is specified in real-world coordinates. There are still three sliders labeled "Object Rotation" left to explain: Well, these three sliders let you rotate the fractal object around the world-axis. Normally you won't use them, so make yourself familiar with all the other settings, and then play around with these sliders. At the bottom of the window there's a button labeled "Graphical Positioning": If you click onto it another window will appear in which you can graphically adjust your position, viewpoint and up-vector. That window is explained in a separate chapter. And yet another (user friendly) possibility to adjust your position needs to be mentioned: If the OpenGL mode is active and the fractal calculated, you can directly rotate in the fractal window:
