Would someone be able to provide documentation or guidance on how to calculate the current xMin, xMax, yMin, yMax values of the section of a scene being viewed on the screen?
Here is what I am attempting to do…
My scene is full-screen at 1920 by 1200 in dimensions. Thus the following are examples of the values I expect to see for each scenario
Example 1:
Origin is at center of screen and no zooming has occurred after startup. Therefor the I would expect the following values to be:
- xMin = -960
- xMax = +960
- yMin = -600
- yMax = +600
Example 2
Origin is at center of screen. I zoom inward once using the mouse wheel. Therefor I would expect the following values to be:
- xMin = -960 plus the offset of the zoom inward
- xMax = +960 minus the offset of the zoom inward
- yMin = -600 plus the offset of the zoom inward
- yMax = +600 minus the offset of the zoom inward
Example 3
Origin is at center of screen. I zoom outward once using the mouse wheel. Therefor I would expect the following values to be:
- xMin = -960 minus the offset of the zoom inward
- xMax = +960 plus the offset of the zoom inward
- yMin = -600 minus the offset of the zoom inward
- yMax = +600 plus the offset of the zoom inward
Any assistance would greatly appreciated.
