Please look at this peice of code :- #include<stdio.h> int main() { int arr[2][2]={1,2,3,4}; printf(\"%d %u %u\",**arr,*arr,arr);
I can easily draw the projection of a 3D set of points onto the plane with normal vector (1,1,1), by using the matrix
Hey, I\'m trying to take a simple image, something开发者_如何转开发 like a black background with colored blocks representing walls. I\'m trying to figure out how to go about starting on something like
