A repository for all OpenGL code... being updated gradually

• Created my first OGL program.
• Learned to create a window, and set a window size and position.
• Learned to set the background display color.
• Learned to implement sound files in my program

• Learned about OpenGL Geometric Primitives.
• Created my virtual world using GL_POLYGON, GL_TRIANGLES, and GL_LINE_STRIP.
• I used glColor3f to fill the color of the Triangle and Polygon.

• Created a FatPaintBrush program with a reshape, keyboard, mouse, motion handler, and Viewport.
• Successfully ran DinoPolyLine File which takes a .txt/.dat file and displays a Dino.
• Completed DinoTilling using a for loop creates a new Viewport for each iteration and creates a dino.
• Completed Dino invert Tilling using nested for loops.
• Completed Dino Zoom in and out using Keys, which zooms in on the up arrow key zooms out on the down arrow key, and reposts the display with updated value.
• Completed viewport panning in which the viewport is variable and can be increased and decreased using a mouse or keyboard
• Created a parametrized Regular polygon and n-gon using lineTo and moveTo functions.
• Implemented the code for Arc.
• Implemented the code for Rose Curves.
• Implemented the code for Rosette (Example from the book).
• Created a circle using equation: x + rcosØ, y + rsinØ

• Implemented and created an Arrow using moveTo and lineTo functions.
• Figure 3.27 rosette
• Implemented and completed Figure 2.44 menu (attached menu with right mouse button)

• Created my Paint Program:
• Learned to render/write text on screen
• Used vector array to draw dots, clicking the left mouse button will create dots and the right mouse clears the dots (push and pop in array)
• Created a shape class that is inherited by different shapes like Triangles, circles, pentagons, cylinder
• Used keyboard handler to render and delete shapes on the screen, on pressing a key a shape is drawn and deleted. (push and pop in vector array)
• Implemented Point2 class and Turtle Graphics:
• Example 3.5.2 (motifs)
• Practice Exercises-> 3.5.1 – 3.5.6 (motifs and meanders)
• Practice Exercises-> 3.5.7 – 3.5.9 (Polyspirals)

• Created a Mario 2D game, learned about RGBApixmap, Enum datatype, reading a bmp file, setting a chromakey, Special keyboard functions and how to move a bmp on screen using keyboard interactions.

• Canvas Class implementation with some more classes including Point2, IntRect, and RealRect.
• Created my own 3 functions drawSun(), drawStar(), and drawSmiley() using Canvas Class.

• Spider game lab:
• Physics engine to check collision between spider & bullet.
• Bounce back logic of the spider if it reaches the wall of the window.
• Object modeling Bullet.
• Use of the gettime() function to determine the speed of the spider at each point second.

• Usage of 2D transformations
• Usage of push & pop matrix for transformations of windmill blade
• Timer Function which increments the value of the angle so the windmill keeps rotating.
• Plane (object) landing using the Timer function.

• Using Transformations to create flakes and a star.
• Dino transformations.

• Modeling and animating a gear wheel.
• Drawing a symmetric object (snowflake) using a Turtle.

• Model a 2D car using transformations and animate it using the Timer function, attached menu to start, restart & exit the program.
• Example of a 2D robot for hierarchical modeling, by using these solutions:
• Independent / Non – hierarchical
• Dependent / Hierarchical.

• Example 5.6.2: A scene composed of wireframe objects.
• Example 5.6.3. A 3D scene rendered with shading.
