Introduction, Callback functions, Color commands, Drawings pixels, lines, polygons using OpenGL, Viewing and Lighting
Explain any two functions in OpenGL. Write the basic commands to draw the pixel and polygon in OpenGL. [5]
These are fundamental OpenGL functions used to delimit the vertices of a primitive or group of primitives. - glBegin(mode) marks the start of a vertex list for a geometric primitive. - glEnd() marks the end of the vertex list. The mode parameter specifies w...
Full solved answer →Write short notes on a. OpenGL b. Flynn's Classification [5]
--- OpenGL (Open Graphics Library) is a software interface (API) that allows a programmer to communicate with graphics hardware for rendering 2D and 3D graphics. It provides a common set of commands that can be used to manage graphics across different appli...
Full solved answer →Write a procedure to draw a line in OpenGL? Describe Painter’s algorithm. [5]
--- In OpenGL, the term line refers to a line segment. Lines are specified in terms of the vertices at their endpoints. OpenGL also supports connected series of line segments and closed connected series of segments. Primitive Description ------ GLLINES Each...
Full solved answer →Give some basic color model. Give the basic command to draw the pixel and polygon in OpenGL. [5]
Color models are mathematical systems for describing colors using numerical values. The basic color models are: - An additive color model used in display devices (monitors, screens). - Colors are formed by combining red, green, and blue light. - Each compon...
