I have a 2D array Z that stores the height at that element's position. Other than using the method here in which I need to create array X and Y with the same size as Z, are there any simpler methods to create a 3D height map? The 3D surface...

I've made a function which successfully pipes data from my C program to gnuplot: void gnuprintabs(FILE *gp,double **RE,double **IM, double x[], int N) { int i,j; fprintf(gp, "splot '-'\n"); for (i=0; i<N; i++) { for(j=0; j<N; j++) { fprintf(gp, "%g %g %g\n", x[i],x[j],sqrt(RE[i][j]*RE[i][j]+IM[i][j]*IM[i][j])); } } fflush(gp); fprintf(gp, "e\n"); } The...

I am thinking about getting a surface 3 as I cant afford a surface pro 3, and was just wondering if I could run the android emulator on it, from the android sdk, to support my app developments. I would be greatful for any thoughts....

I have 3 sets of 3D co-ordinates and I have fitted planes to each set. Now, I want to plot all the data points and the 3 planes in one figure. So far, I have the following function: function [fitresult, gof] = create_fit(xx, yy, zz, grp) [xData, yData, zData] =...

Good day everyone; I have a M*N matrix and I have two coordinate vectors X and Y, where X has the length of M and Y has the length of N but they have different values because M is an array index and X is a Latitude coordinate, for example...

I have a ComboBox with two items (Buy and Sell). but when PropertyChanged (Sell) still not update comboBox(still selected Buy). I 'm working with VS2013 with .Net 4.5 with Windows app .Please help me.

When I run following script in R, the fitted line doesn't appear in the plot. I want it to appear though. Can you help me? rm(list=ls()) # Surface tension surft <- c(49.1, 51.7, 50.7, 52.0, 53.5, 52.9, 55.1, 59, 62.5, 66.4, 69.0, 73.8) # surface tension of mixtures # Mole...

Lets consider that I have five 2D-Matrices which describe the magnetic field at different z-Layers. A nice, smoothed version of a 2D-Surface plot can be obtained as follows: data2_I<-matrix(c(1.0,1.0,0.6,0.6,0.7,0.9,0.9,0.5,0.5,0.5,0.7,0.9,0.9,0.6,0.3,0.4,0.7,0.9,0.9,0.7,0.5,0.5,0.6,0.9,0.9,0.7,0.6,0.6,1.0,1.0), nrow=5) Z = as.vector(data2_I) length(Z) XY=data.frame(x=as.numeric(gl(5,1,30)),y=as.numeric(gl(5,6,30))) t=Tps(XY,Z) surface(t) Now it would be great if I could get a 3D-plot where at...

I am trying to create a cylindrical 3D surface plot using Python, where my independent variables are z and theta, and the dependent variable is radius (i.e., radius is a function of vertical position and azimuth angle). So far, I have only been able to find ways to create a...

I'm using a library called Awesomium and it has the following function: void Awesomium::BitmapSurface::CopyTo ( unsigned char * dest_buffer, // output int dest_row_span, // input that I can select int dest_depth, // input that I can select bool convert_to_rgba, // input that I can select bool flip_y // input that...

I'm plotting multiple surfaces on the same figure using matplotlib, and I'd like to see only the topmost surface, as matlab shows. Matlab 3D view: Matlab top view: Matplotlib 3D view: Matplotlib top view: How can I get Matplotlib to show a result similar to Matlab, in which whatever topmost...

everyone: I am working with SurfaceTexture in Android but I am not able to understand Its API: getTransformMatrix(float[] mtx), the API doc is as follows: /** * Retrieve the 4x4 texture coordinate transform matrix associated with the texture image set by * the most recent call to updateTexImage. * *...

I am currently trying some things using pixel manipulation and I would like to set the pixel format of a SDL_Surface. The problem here is that I am loading up an image with the SDL_image.h. So I have to create a texture from a surface like this: surface = IMG_Load(filePath);...

I have a surface in matlab which is plotted using the following code: [xi, yi] = meshgrid(S/K, days); vq = griddata(S/K, days, rbf/K, xi, yi,'natural'); mesh(xi,yi,vq) The resulting image is quite rough, and has lots of grid lines as there are roughly 200 data points in each vector. Is it...

Refer to the attached image. I want to display the image in Matlab using the function surf(). However, I only want to display the region of the actual object without the background (the pale-green region surrounding the actual object which has 0 value). How to do that? I tried replacing...

This is my code and I was trying to make a rectangle: import pygame import sys pygame.init() color = [255,20,78] black = [0,0,0] screen = pygame.display.set_mode((800,600), 0, 32) pygame.display.set_caption("Rectangle") while True: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() sys.exit() screen.fill(color) pygame.draw.rect(color, black, [400,300,10,10]) pygame.display.update() I don't understand what...

I've been unable to find a way of producing the plot described in the title, does anyone know how to do this if it's possible? I'd like to plot a surface from a function, and plot points from a file, and have lines drawn between the points and the surface....
