thanks i think these basic i need to know now i have question
Q1 if camera is used then will this(gluPerspective) updated.if yes how
Q2 the code fraction
glMatrixMode(GL_PROJECTION);<- i know projetion(farther smaller nearer bigger(perspective,frustum))
glLoadIdentity();
gluPerspective(let it filled);
glMatrixMode(GL_MODELVIEW);<- how it fnctioning
glLoadIdentity();
and
these glMatrixMode()glLoadIdentity() used two times in codes
at DisplayFunc and ReshapeFunc why? Without them theres only screen of glClearColor() or black?
Q3. if object either side of zNear,zFar,two lines make angle at y then is object invisible(i think must be)?
(Please Help me cause i programmed many code with them but don’t know how that work like know how to drive but don’t know how to repair(I am only 16.9 year old and know vector,Matrix(all of summ…,Multi…),Little bit plane)
so please help me regard these which is not out of that maths
)
thanks in advance
