// Create a new LLRect with origin at (0, 0) and size 100x50 LLRect rect; rect.setOriginAndSize(LLVector2(0, 0), LLVector2(100, 50)); // Move the rectangle to a new center point (50, 50) and set size to 75x75 rect.setCenterAndSize(LLVector2(50, 50), LLVector2(75, 75)); // Define a rectangle using min and max coordinates LLVector2 min(0, 0); LLVector2 max(100, 75); LLRect rect2; rect2.setMinMax(min, max);In these examples, we are creating new instances of the LLRect class and setting their coordinates and dimensions using the set methods. These methods take LLVector2 objects as parameters, which represent a two-dimensional point with x and y coordinates. The package library for the LLRect class is the Second Life Application Framework, which is a collection of libraries used in the Second Life Viewer for creating applications and scripted objects.
