what is computer graphics
it is the sience that study how computer is able to render 2D and 3D graphics
what is the difference between the sampled-based graphics and the geometry-based graphics
the sampled-based study how to send or git a picture from the camara or scanner and render it or edit it
while the graphic-based study how to create these picture and draw it in an environment then render it to 2d
what is Perspective View
it is the same prespective as the prespective of an eye
in the prespective view the size of an object ____ when we the distance get longer ?
1- increase
2- decrease
3- stay the same
2-decrease
in the Orthographic view the size of an object ____ when we the distance get longer ?
1- increase
2- decrease
3- stay the same
3-stay the same
aspect ratio is ?
it is the ratio of its width to its height
what is Projection ?
it is the process of converting a 3D object into a 2D object
what is rasterization algorithm ?
Rasterization is the technique of taking an image described in a vector graphics format and transform it into pixels
what is the different between rester display and vector display ?
in rester display we transform the image to a pixels while in the vector display we transform it to set of points or a vector
and the CRT move to draw this lines instead of just lighting a point
we specify the object features and color in ?
1- modeling
2- rendering
3- display
1- modeling
