CSCI 441 - Computer Graphics

For this assignment, you are to create an OpenGL/GLFW program that contains either your Hero or a vehicle to transport your Hero drawn in 3D. Be sure to use the pieces from the previous labs as the basis of your program. The user will be able to move the 3D character forward and change its heading, as well as control a camera which rotates around the character. The character itself can be constructed from CSCI441 3D Objects or custom VAO/VBO objects in a hierarchical fashion, like the previous assignment. The character must have some level of animation when moving and/or stopped. Your character must have a clear front and back which are aligned with its current heading.

Out for a Sunday drive through the city/park.

In order to be able to render your 3D Hero, you will need to create a shader program comprised of a vertex and fragment shader. You must implement the full Phong Illumination Model (diffuse + specular + ambient) Gouraud Shading expanded from Lab05. It is fine to use a directional light for this assignment, but a point light may be used instead if you'd like.

FFP-Free: Feel free to try your own unique and custom effect and deviate from the shading models we have looked at so far.

Whatever your shading implementation, we must be able to differentiate objects from one another using different materials.

Pressing 'w' will move the character forward along the heading and pressing 's' will move the character backwards along the heading. Pressing 'a' or 'd' will turn the character's heading left or right respectively. The user must be able to control an arcball camera with the mouse that is centered around the character (looking at the character's current X, Y, Z). In other words, the user can change theta and phi to rotate the camera around the character as the character moves and the character will stay in the center of the screen.

Additionally, there must be some other objects in the scene so that we can see the character moving. You can now bring your world to life! At a minimum, this should include a grid of line strips and additionally can be as sophisticated as a city or forest. Your character cannot be able to move off the grid. Bounds checking will need to be performed to keep the character in its world. You do not need to worry about checking if your character has collided with one of the scene objects (such as a building or tree). For an added challenge though, feel free to add some simple collision detection to prevent your character from running through every object.

Be creative! Your character can be a 3D humanoid representation of your Hero or a vehicle to transport your Hero. The vehicle does not need to be a car, but any type of transportation device (wagon, helicopter, plane, scooter, rocket ship, etc). It would be a wise idea to have a function drawCharacter() that does all of the hierarchical drawing for your character. You will be using this character again in future assignments.

Using viewports, render additional camera views, and overlay them on top of the normal 3D view. Your viewport may occupy any portion of the space on the screen; you could make the viewport split-screen style or have it occupy a corner of the screen like a mini-map. In order to receive full credit, you MUST have multiple objects making up a scene (i.e., boxes of different size as a city, cones stacked on top of cylinders for trees, etc.). In other words, the scene must be more complicated than just a grid for the ground.

Watch out for that tree!

If you want to implement additional camera models beyond the arcball camera, here is a list of camera models you can choose from:

1. First-Person Cam: The view looking from the point-of-view of the character along its heading.
2. Sky Cam: A camera positioned directly overhead the character and looking straight down. The camera must follow the character and turn with the character so that the character is always pointing forward (towards the top of your window).
3. Third-Person Cam: A camera that is located just behind the character and looking along the character's heading. The camera must follow the character and stay a fixed distance behind the character. (Think Mario Kart)
4. Reverse Cam: Similar to the third-person cam, but instead is positioned in front of the character and looking backwards along the character's heading.
5. First-Person Movable Cam: Position as described by the first-person camera, but the user can control the direction of view to mimic the character looking around the world.

The user should be able to toggle between any available cameras by pressing the 1-9 number keys.
