Thanks for the video! Question: Once I have a 3D surface, is there any way to interpolate to find a Z value based on an X1 and X2 values that dont have a Z value defined? In my case, Z is not based on a formula.
I love the explanation, it's so clear! Anyway could you help me to draw a 3d graphs but rather different than these one on video. My data is of the format (x,y,z,T), where x,y and z are axes indicating a point and T is the colour value at the specified point. I'm so thankful if you could make video to solve my problems, thanks in advance!
Great question. To be able to see individual points on a 3D graph you will want to select a point style, otherwise the points will be too small to view. Ex. to create a red diamond: plot3(0,0,0, 'rd'). and since you want more than one point to be displayed on the graph use: hold on command at the beginning of the program. If you are given the color in a variable T. ex T='r' then you can combine it with a shape: strcat(T, 'd') to use as the 4th argument to plot3. If you need me to create a video, send me some of the exact x,y,z, T values and any other requirements and I can create a video today.
@@PainlessProgramming first of all thanks for the quick response. yes it will be very helpful if you could make a video because I don't know much about 3D graphics. here are some of my data in (x, y, z, T) format: (3,25,300,Yellow),(2,25,500,Green),(1,75,700,Red),(0,50,500,Blue),(-1,50,300,Yellow),(-2,50,500,Green),(-3,75,700,Red). and could you show me how to plot in a shape other than points, like a mesh or maybe a surface (if it's possible). Once again I thank you very much for the help.
Hello there, thanks for the great video! I have a similar program that I need to do in MATLAB. I have around 100 rows of X,Y,Z points as a data file, to be considered as a matrix. And 100 rows in 1 column of binary data, as a vector. I need to slice the 100 rows of xyz matrix data, with the vector data to obtain a 3D model. Could I contact you in person, maybe an email, regarding this problem? I do have a rough code, but would like if I get some help from someone who's well versed in MATLAB.
this is world class!!! thank you soo much
Thanks so much for the comment!
such an underrated video, better than my damn university professor teachings 😂
Nice explain

thanks for the video. Please I want to plot a 3D surf of two equations united by ‘if’ and ‘else’ statements. For example. “if X>Y Z=2X+Y elseif X
Can you give me the 2 equations you want to start with?
