In this assignment, you will use the seen in the pervious assignment/Lab. You will implement multi texturing mapping to the cube or pyramid . You will use different textures, one for each face of the cube/ pyramid. You will also add light source, material and shading characteristics to the scene. The light source should be placed in a default position and orientation. The users then provides incremental changes to modify the camera and light source parameters such as location, light color, brightness and whether its infinite or global .
Implementation suggestion
• Your program must support keyboard commands to control light rotation and orientation. The user can adjust the light using the following keystrokes:
§ SHIFT+RIGHT / SHIFT+LEFT increase/decrease LIGHT X location by small amount (e.g. 0.1)
§ SHIFT+UP/ SHIFT+DOWN increase/decrease LIGHT Y location by small amount (e.g. 0.1)
§ RIGHT/LEFT increase/decrease CAMERA X location by small amount (e.g. 0.1)
§ UP/DOWN increase/decrease CAMERA Y location by small amount (e.g. 0.1)
§ +/- increase/decrease the brightness (color pigment) of light source by small a mount (apply on all properties of light source- Ambient, diffusive and specular)
e.g.
-----------------
Switch case if + è
If A_Red and A_Green , A_Blue < 1è A_Red+=0.1 , A_Green+=0.1 and A_Blue+=0.1 Elseèassign initial value A_Red=0.2 , A_Green=0.2 and A_Blue=0.2
-----------------
The values will be updated anywhere you call the light_ambiant array glLightfv(GL_LIGHT0, GL_AMBIENT, light_ambiant);
Note: Do this for all arrays (Ambient, diffusive and specular) to increase their brightness
float A_Red = 0.2, A_Green= 0.2, A_Blue= 0.2 ;
GLfloat light_ambiant [] = { A_Red, A_Green, A_Green, 1.0};
§ ‘C’/’c’ change the light source color to a random color (apply on all properties of light source - Ambient, diffusive and specular)
e.g.
float C_Red, C_Green, C_Blue;
GLfloat light_ambiant [] = { A_Red, A_Green, A_Green, 1.0};
-----------------
Switch case if C è
//Generate Random color (use srand (time(NULL); in main before using rand() func); ) C_Red = (float) rand()/RAND_MAX ;
C_Green = (float) rand()/RAND_MAX; C_Blue = (float) rand()/RAND_MAX ;
// reassign value for ambient and other arrays
A_Red= C_Green, A_Green= C_Green and A_Blue= C_Green;
//For Diffusive and speculare you might want to increase the brightness of the initial color e.g. D_Red= C_Green + 0.2 , D_Green= C_Green+ 0.2 and D_Blue= C_Green+ 0.2;
-----------------
//The values will be updated anywhere you call the light_ambiant array glLightfv(GL_LIGHT0, GL_AMBIENT, light_ambiant);
§ ‘G’/’g’ change light source from infinite to global and vise versa (apply on all properties of light source- ambient, diffusive and specular)
e.g.
-----------------
Switch case if G è
If A_global ==1.0èA_global =0.0 Else è A_global=1.0
§ ESCAP exit the program
• When the user changes the light source setting, the program should update the light sorce and redraw the seen.
• Be creative.
