Python TkInter: Creating a Window which runs my custom code

由 可紊 提交于 2020-06-17 09:27:50
问题 I am Creating a python custom code to Visualise scientific/medical data in 3D. This code should be implemented in the GUI I am creating with TKInter, so as to visualise these data sets directly in the GUI. If I already have the code written up is there a way I can run this code in my GUI and subsequently open and run the visualisation window directly in the TKInter GUI ??? Is it possible to create custom windows inside with TKInter which contain more complex code and allow the user to

What's the simple way to compute the diagonal length of a 3D mesh bounding box?

由 南笙酒味 提交于 2020-06-16 19:06:11
问题 I would like to compute the diagonal length of the bounding box of a 3D mesh. Using C++, I iterate of the vertices and search for the (min,max) of X coordinates, (min,max) of Y coordinates and (min,max) of Z coordinates. However I don't know how can I exploit these obtained min/max for the computation of the diagonal length of the bounding box. Any help please? 回答1: For simplicity let us consider a list of n 3D points (point cloud) as input (instead of mesh) which is enough for polygonal

How to redraw partially in opengl Es 2.0

由 雨燕双飞 提交于 2020-05-31 05:28:27
问题 As per my need I want to redraw only some part of the scene for each frame instead of redrawing the entire scene only if some portion of it is updated. Is there a way to do that in OpenGL ES 2.0? Please any input on this will be really helpful 回答1: OpenGL does not really support incremental rendering. You need to draw the entire frame every time you are asked to redraw. The closest I can think of is that you render your static data to an offscreen framebuffer, using a FBO (Frame Buffer Object

How to make new grid from two diiferent data lat lon coordinates

由 有些话、适合烂在心里 提交于 2020-05-24 05:45:52
问题 I have two data sets A and B. Each data set have lat,lon and temperature but different lengths A=[200,3] B=[250,3]. I would like perform interpolate A and B and display the temperature(average temperature which are close lat lon from 2 sets). It would be great help someone know how to handle it. I tried from here https://stackoverflow.com/a/56628900/13258046 mesh1=df_A[['latitude(deg)','longititude(deg)']] mesh2=df_D[['latitude(deg)','longititude(deg)']] the shape of the data is mesh1.shape:

Error encountered while plotting right half of facial surface mesh in R by subsetting full face vertices and indices data

由 两盒软妹~` 提交于 2020-05-17 05:46:20
问题 I have vertices and indices data for human face here. I have a post one year ago on plotting 3D facial surface mesh based on these data. Now, I want to plot only the right half and mid-facial vertices while ignoring the left side vertices. Based on my earlier plot, I tried the following code: library(tidyverse) library(readxl) library(rgl) vb <- read_excel("...\\vb.xlsx", sheet = "Sheet1", col_names = F) it <- read_excel("...\\it.xlsx", sheet = "Sheet1", col_names = F) # Extract vertices for

Camera arguments in Three.js

由 江枫思渺然 提交于 2020-05-09 18:04:22
问题 This is how a camera is instantiated: var camera = new THREE.PerspectiveCamera( VIEW_ANGLE, ASPECT, NEAR, FAR ); What do these values mean? 回答1: The first param is FOV means field of view, imagine a camera on a tripod, if you change lens to wide angle you get a higher FOV. Try to imagine a cone coming out from the camera, it can only see objects in that area. ASPECT means aspect ratio, a widescreen TV is 16/9 and old ones were 4/3, usually just give it the screen width/height or the dims of a
