First look at the original source code to run the effect, whether it is necessary.

Here, the three-dimensional polygon graph is the z-axis data generated by the function, and of course we can use the color of the image as the z axis.

Preparation, VS2008 and above, bloggers use VS2017, need to upgrade the project.

Problem:

1, use the color of the picture as the third axis (Z axis)

Solution Ideas:

1.1 See how Z-axis data is generated in the source code

1.2 Read the picture in and convert it into an RGB array

1.3 Replace the image RGB array with the original z-axis data

Find the code in WINDOW1:

1.1 Red indicates that a function is used to assign a value to the z-axis.

//***************************** Convert a picture into a color array ***************************         Public Staticsystem.drawing.color[,] Img2color (String imgfile) {System.Drawing.Bitmap img=NewSystem.Drawing.Bitmap (Imgfile); system.drawing.color[,] Allcolor=Newsystem.drawing.color[img. Height, IMG.            Width];  for(inth =0; H < img. Height; h++)                 for(intW =0; W < IMG. Width; w++) {allcolor[h, W]=img.                GetPixel (W, h); } GC.            Collect (); returnAllcolor;}

Put the following code in the Testsurffaceplot method:

float[] NewData =New float[10000]; system.drawing.color[,] Allcolor= Img2color ("xxx111.jpg"); intwidth = -;  for(intj =0; J <10000; J + +) {Color Newcolor=NewColor (); if(allcolor[j% width, j/width]. B < -&& allcolor[j% width, j/width]. R < -&& allcolor[j% width, j/width]. G < -) {Newcolor.a=255; Newcolor.b=255; NEWCOLOR.R=0; NEWCOLOR.G=255; }                Else{NEWCOLOR.A= allcolor[j% width, j/width].                    A NEWCOLOR.R= allcolor[j% width, j/width].                    R NEWCOLOR.G= allcolor[j% width, j/width].                    G Newcolor.b= allcolor[j% width, j/width].                B } M_3dchart[j].color=Newcolor; }

Done.
