![]() ![]() In particular, using the new "shape recording" functionality available in PShape (see PShape tutorial) can greatly increase speed in P3D mode. Keep in mind that OpenGL is not magic pixie dust that makes any sketch faster (though it's close), you will also need to carefully consider the techniques you are using to make the drawing as well. In other words, some of the work required to draw all the pixels in the window can happen on your computer's graphics card which is often more efficient. You want your sketch to run faster! P2D and P3D make use of OpenGL-compatible graphics hardware.How far in front or behind the window does a pixel live? Now, we all know there are no actual pixels floating in the air in front of or behind your screen! What we're talking about here is how to use the theoretical z-axis to create the illusion of three-dimensional space in your Processing window.P3D is required for this. You are drawing in 3D! In three-dimensional space, a third axis (the z-axis) refers to the depth of any given point.Switching to P2D or P3D is advisable given one of the following scenarios: It provides the most elegant and accurate results when drawing in 2D. In most cases, particularly when you are first learning Processing, you will want to use the default renderer setting. When deciding which renderer to use, you are balancing a number of factors: speed, accuracy, and general usefulness of the available features. For example, the default renderer employs existing Java (the language Processing.py is built on) 2D libraries to draw shapes, set colors, display text, etc. Now, you may be wondering: "Which render mode should I choose and why?" The mode itself tells Processing what to do behind the scenes when drawing the display window. To use a non-default renderer, you can specify via the size() function. In Processing, there are many render modes: the default renderer, P2D, P3D, and PDF. This work is licensed under a Creative CommonsĪttribution-NonCommercial-ShareAlike 4.0 International License.
