Public partial class Plot3DMainForm : Formĭouble x, y, z // observer coordinates public Plot3DMainForm() Do you think any of your source code could be useful towards a project like this? Is this a project you might be interested in taking on?ĭoes anyone in the community have ideas or know of code samples that apply to this problem? A simulator would assist students in understanding how changes in their search beacon's location, angle, etc can affect the signal it receives and assist them in interpreting what that means to better equip them to make these analysis in the field. Eventually I would use this in a search simulator where virtual search beacons receive the signal from the transmitting beacon. The point of this exercise is to illustrate how an avalanche beacon transmits a signal and how the waves of this signal can affect searchers receiving a signal. So, instead of plotting on a surface, the plot is in space. I am looking for code that can plot radio waves from a dipole antenna at a given frequency in 3 dimensional space. Windows.Forms 3D Graph Render Control in C# The completely rewritten version of this project can be found here: You can rotate the 3D surface with the mouse without any delay. It is lightning fast if you use up to 3000 polygons. In a few minutes you will get it working. I wrote a completely reusable Control which you can integrate easily into your application. I fixed the bugs and added lots a of new features and cleaned up the code. Therefore I invested a week to rewrite this project from the scratch.įorm the original code nearly nothing is left. The 3D surface cannot be moved, rotated, etc with the mouse.Īxis and coordinate system are not implemented. People ask here in the comments for features: I found it also very strange that formulas use variables x1 and x2 instead of x and y. Specifying 3D data from another data source is not possible. Only support for functions is implemented. The drawing is slow because the code is not optimized for maximum speed. When looking the 3D surface from the bottom it seems to be reversed. The drawing has a bug which results in artifacts when rotating. Specifying 3D observer coordinates is a misdesign. Since many years this project did not get any update although there are several issues and a severe bug. The other one compiles a given formula to a function delegate, providing simple parser services. The first one encapsulates an array of Color entries. Render the surface on given graphics.Īdditional classes ColorSchema and CompiledFunction are interesting parts of the code. Calculates screen coordinates for the 3D point. ReCalculateTransformationsCoeficients - Recalculates transformations' coefficients on the basis of new parameters.ColorSchema - Color schema assigned to mesh.Function - Function used to calculate surface vertices.I've used it in programs written for courses of Optimization Methods, Identification, Calculus (Mathematical Analysis), and Dimensional Analysis. Its application varies from simply admiring beautiful 3D surfaces to data visualization purposes, to stuff whatever one needs. Simplicity has, of course, its price - the rendering process isn't as fast as when using hardware acceleration. It doesn't use OpenGL or DirectX or stuff like that. This article describes a simple method of rendering 3D surfaces on a 2D plane. Download compiled application - 12.9 KB.You are receiving this because you are subscribed to this thread. It has little effect on the issue though. Note: I also changed the stride values for the surface plot to theirĭefault values. # Calculate distance of all points to center.ĭist = np.sqrt((I - 100)**2 + (J - 100)**2) The issue is that not all of the points are visible when they are on the I am trying to generate a 3-D surface plot with a 3-D scatter plot Matplotlib: 1.5.3 (from Anaconda installer) Note: I also changed the stride values for the surface plot to their default values. They should not be visible through the surface unless the surface plot's alpha is set below 1. randint( 0, 200, size = 100)Īnother issue is that at some angles, points on the other side of the surface plot's peak are visible. # Generate points to represent population. plot_surface( x, y, z, rstride = 1, cstride = 1, linewidths = 0, cmap = 'terrain') # Calculate distance of all points to center.
