Hi, this is a problem which has been plaguing me for quite some time now… Hope someone can help me?
I have a code that draws 2 objects based on condition ‘a’.If ‘a’ is 1, it draws the first object, if ‘a’ is 2, it draws the second object. ‘a’ toggles every now and then from 1 to 2.
These are 4 observations I made.
1)If object 1 is drawn alone, there is no problem.
2)If object 2 is drawn alone, the color of object 2 is different from what I expected. (it seems more brown than orange)
3)If object 1 is drawn first, followed by object 2, there is no problem.
4)If object 2 is drawn first followed by object 1, the color of object 2 is the same as condition (2), meaning it is more brown than orange.
Below is my code in this area, pls help!!
/////////////////////////////////////////////
static GLfloat color[8][3]=
