* or undefined if no entity is at that location. * Returns the top-most entity at the provided window coordinates By applying various heuristics to the data we give it, the Entity API is able to provide flexible, high-performance visualization while exposing a consistent, easy to learn, and easy to use interface. When drawing the rectangle, we may also add another agrument to the draw command to define the line thickness of the rectangle (as opposed to being filled in as. While the Entity API actually uses the Primitive API under the hood, that’s an implementation detail we (almost) never have to concern ourselves with. It also provides constructs for easily building complex, time-dynamic visualization in a way that fits naturally alongside static data. ' I want to draw a circle with a thick outline ' You could create a Script and call it in the draw end event of you Object, where you need the circle: Just a. It lets us concentrate on the presentation of data rather than worrying about the underlying mechanism of visualization. This are the main code-block you need: drawsetcolour (cblack) // Set the color of your outline drawcircle (x, y, radius, true) // The Circle, the word 'true' only draws the outline. The Entity API exposes a set of consistently designed high-level objects that aggregate related visualization and information into a unified data structure, which we call an Entity. While this approach is powerful and flexible, most applications are better served with a higher level of abstraction. If youre creating a new plan, brainstorm designs based on the size and shape of the location on which to build. You can draw points and line segments with the following. Furthermore, each has different performance characteristics and requires different best practices. setPenRadius() and tPenColor() control the line thickness and color. Each type of visualization is its own distinct feature. Loading a model is different from creating a billboard, and both are radically different from creating a polygon. weight (float, default 2.0) Width of outline around each circle (pixels). It is structured to provide a flexible implementation for graphics developers, not for API consistency. It then draws a rectangle to the surface with an 80 alpha (this is the 'darkness' that we are going to illuminate), before changing to a subtractive blend mode. outline indicates whether only the outline must be drawn (true) or it should be filled (false). drawrectangle(x1,y1,x2,y2,outline) Draws a rectangle. The low-level Primitive API exposes the minimal amount of abstraction needed to perform the task at hand. One is to use drawlinewidth() to draw the circle segments yourself. drawlinewidth(x1,y1,x2,y2,w) Draws a line from (x1,y1) to (x2,y2) with width w. CesiumJS has a rich API for spatial data that can be split into two categories: a low-level Primitive API geared towards graphics developers, and a high-level Entity API for data-driven visualization.
