WebIn the other samples we had the F at (45, 150, 0) but in the last sample it's been moved to (-150, 0, -360). Why did it need to be moved so far away? The reason is up until this last sample our m4.projection function has made a projection from pixels to clip space. That means the area we were displaying represented 400x300 pixels. WebPerspective projection defines a process for transforming positions into clip space, such that these clip space positions will appear to be a perspective projection of a 3D world. …
WebA perspective projection captures a larger space of the world. In 2D, the shape of the perspective projection is a regular trapezoid (a quadrilateral that has only one pair of parallel sides, and the other pair of sides have the same slope). In 3D, the shape is called a frustum; essentially, a pyramid with the tip chopped off. Figure 4.5.
