Default palette size for normal graphics driver is 16 i.e) the color number rages from 0 to 15 To use rgb color modes we have to choose VGA or IBM 8514 as a graphics driver For VGA, Palette size is 16 i.e) color number ranges from 0-16 For IBM 8514, Palette size is 256 i.e) color number ranges from 0-255, we can also say it as VGA with 256 palette size By using setrgbpalette function we can generate RGB colors, we can generate colors with respect to Palette size. This function replaces the default palette colors with the generated Palette colors. Syntax: void setrgbpalette(int colornum, int red, int green, int blue); /* colornum - color number in palette (0-15 or 0-255 depens on graphics driver) red - color value for red (0-255) green - color value for green (0-255) blue - color value for blue (0-255) */ Example: #include<graphics.h> #include<stdio.h> #include<conio.h> #include<stdlib.h> #include<time.h> void main(){ in...

I hope you will remember  engineering graphics in your first year of engineering, This basic idea will be useful in understanding the concept.  Usually projection is nothing but the representation of a 3D object in a 2D form with the angle we view. Basically we represent a 3D object in a 2D form with three basic views Front View Top View Side View In the following code, the user is asked to enter the co-ordinates for a 2D object and with the depth we enter it will generate a 3D object. For example , consider a cube - the view you see without a depth will be a square. Note: In computer graphics the co-ordinates start from top-left (0,0) of your screen CODE : #include <stdio.h> #include <stdlib.h> #include <graphics.h> #include <conio.h> int ARRAY_SIZE; int array_max(int *arr, int returnIndex); int array_min(int *arr, int returnIndex); void draw3d(int sides, int *x, int *y, int depth); void drawFrontView(int sides, int *x, int *y);...
