I used Offset to create the bottom profile of the basin. Vectors in 2D and 3D Example 2: A light plane flies at a heading of due north (direction which airplane is pointed) at air speed (speed relative to the air) of 120 km/hr in a wind blowing due east at 50 km/hr. The curve and the straight lines were copy/rotated about the basin’s center line to make the opposite half. That gives half the single basin profile. I drew the Bezier curve on the far left with Fredo6’s Bezier Spline tool and added straight edge segments for the depth of the trough and half it’s width.
Then I drew the curve profile for the inside of the basin. So here I’ve made the blank match the thickness of the back wall of the basins. Pixels appear like little squares on graph paper when the image is zoomed in or enlarged. The problem many folks have is they start thinking only in 2D and they wind up creating trouble when they go 3D. Raster images are made of pixels or tiny dots that use color and tone to produce the image.

Later single-engined experimental craft like the X-31 used a different vectoring system with paddles behind the engine exhaust, which can be rotated as well as pivoted allowing thrust to be vectored in a "spiral" fashion, providing roll control and thus full 3D vectoring from a single engine.I think I had a series of accumulated errors along the way that just held me up.Īs for my approach, I would maybe do it something like the following:įirst, I would draw a 3D blank to start. The F-16 VISTA tech demonstrator allowed vectoring of the engine's thrust in any direction behind the aircraft, but because the aircraft was single-engined and used a system based on the engine's existing "turkey feathers" (which allow the engine to regulate internal combustion pressure and exhaust velocity by restricting the diameter of the nozzle), the craft did not have roll control in a post-stall situation. Vector3D 's z property is still taken into account for sprites on the same sorting layer and with the same. Later F-22s (and I believe a retrofit of earlier ones) allowed the nozzles to move independently which also granted roll control using thrust vectoring, making the system 2D. All the positions of objects are still plotted in 3 dimensional space so if you use Vector2D there will just be an unnecessary cast from Vector2D to Vector3D and the third dimension will just be set to 0. It was seen on early-block F-22s, whose thrust-vectoring nozzles can redirect thrust only up or down, and on these early blocks the nozzles of the two engines moved together in the same direction. Yes, there is such a thing as 1D thrust vectoring.
Vector 2d vs vector 3d vs raster 3d plus#
Therefore, 2D vectoring allows control over two degrees of freedom (typically pitch plus either roll or yaw) while 3D controls all three.Īs previously mentioned, the difference between 2D and 3D is the number of degrees of freedom that can be controlled using thrust vectoring. The number of "dimensions" of thrust vectoring relates directly to how many degrees of freedom can be manipulated using only the vectored engine thrust. An aircraft traditionally has three "degrees of freedom" in aerodynamic maneuverability pitch, yaw and roll. The problem many folks have is they start thinking only in 2D and they wind up creating trouble when they go 3D.
