A viewport is a polygon viewing region in computer graphics. In computer graphics theory, there are two region-like notions of relevance when rendering some objects to an image. In textbook terminology, the world coordinate window is the area of interest (meaning what the user wants to visualize) in some application-specific coordinates, e.g ...
Clipping, in the context of computer graphics, is a method to selectively enable or disable rendering operations within a defined region of interest. Mathematically, clipping can be described using the terminology of constructive geometry. A rendering algorithm only draws pixels in the intersection between the clip region and the scene model.
Portrait orientation is still used occasionally within some arcade and home titles (either giving the option of using black bars or rotating the display), primarily in the vertical shoot 'em up genre due to considerations of aesthetics, tradition and gameplay. Games made primarily for mobile devices are often designed around portrait mode play.
Alternatively, one could use clipping techniques, replacing the variables with values of the point that are out of the FOV-angle and the point inside Camera Matrix. This technique, also known as "Inverse Camera", is a Perspective Projection Calculus with known values to calculate the last point on visible angle, projecting from the invisible ...
Caret navigation usually also incorporates a form of viewport scrolling control where the caret moves freely within certain margins of a static display but triggers a scrolling event upon reaching one of the margins (either the edge of the screen/window/text field or a point a certain number of lines/characters within said edge). The view ...
The computer graphics pipeline, also known as the rendering pipeline, or graphics pipeline, is a framework within computer graphics that outlines the necessary procedures for transforming a three-dimensional (3D) scene into a two-dimensional (2D) representation on a screen. [1]
An example of the 3D cursor within Blender (center) The idea of a cursor being used as a marker or insertion point for new data or transformations, such as rotation, can be extended to a 3D modeling environment. Blender, for instance, uses a 3D cursor to determine where operations such as placing meshes are to take place in the 3D viewport. [23]
The sense of the rotation is to rotate from m towards n: the geometric product is not commutative so the product nm is the inverse rotation, with sense from n to m. Conversely all simple rotations can be generated this way, with two reflections, by two unit vectors in the plane of rotation separated by half the desired angle of rotation.
