Echart polar coordinates, azimuth and distance diagram, icon symbol rotation and size, color gradient

Background: Participating in an interactive chart project, the customer had a need for polar coordinate comparison to display different types of indicator data in different directions and distances. Specifically, the attribute fields are: Source, distance, orientation, ID, rotation angle, size Let’s look at the renderings first: Technical points: Legend description: The distance is the radial […]

k-Wave丨Photoacoustic imaging simulation丨Definition of Gaussian sensor frequency response + comparison of simulation functions + setting of initial pressure gradient (5)

This article introduces– 1.How to define Gaussian sensor frequency response: How to express the frequency response of a detector (for example: piezoelectric ultrasonic transducer) when the response has a Gaussian shape, based on the example of a homogeneous propagation medium; 2.Comparison of simulated functions: Introducing a brief comparison between the simulated functions “kspaceFirstOrder2D” and “kspaceecondorder”. […]

Unity hand-painted Mesh realizes color gradient

The requirements I received are as follows: Please see the final renderings Let’s start Simplifying the requirement is to create a Mesh with a width*2 and a color gradient based on 2 points. Creating a square Mesh requires four points, and what I need here is only two, so I regard the two points as […]
