"Bort"

Midterm Project – The Alchemist's Guild: Guide three heros through a lush guild staging area rendered with full Attenuated Phong lighting. Three additive lights (directional sun, warm point lantern, and cool spotlight) illuminate procedural foliage, a skybox, and three cameras (arcball, free-fly, first-person) with picture-in-picture preview. Bort features hierarchical animation, blinking and bobbing, while the resilient world includes tree canopies with double-sided leaves, bushes, and a hovering hero roster built on OpenGL 4.1, GLFW, GLM, and the CSCI441 engine framework.

Assignment 3 – Hero in 3D: Build a 3D animated hero/vehicle with full Phong lighting using custom vertex and fragment shaders. The character moves through a bounded 3D world using WASD controls (forward/backward movement along heading, left/right turning) while an arcball camera orbits around the character, controlled via mouse drag and Shift+drag zoom. The scene includes a ground grid and scattered objects for spatial reference. The lighting model implements ambient, diffuse, and specular components with directional lighting, using separate material properties for different objects. Matrix transformations handle the character's position and orientation, camera positioning, and hierarchical object transforms. Built with OpenGL 4.1, GLFW, GLM, and CSCI441 utilities, demonstrating modern shader-based rendering, 3D mathematics, and interactive camera controls.

Assignment 2 – Animated 2D Hero: Build an animated 2D hero entirely from OpenGL vertex data and simple transformation math. The character is constructed from a few basic VAOs (body, head, eyes, pupils, arms, mouth, and small projectile shapes) and drawn with an orthographic projection so window pixels map directly to coordinates. Hierarchical transforms (push/pop of translations, rotations, and scales) drive the character’s parts; arms pivot at the shoulder, the head sits above the body, and pupils track the mouse. The scene is interactive: WASD / arrow keys move the hero (wrapping the world and updating the background map), the left mouse button fires a projectile toward the cursor, and holding B while clicking produces a green “booger” projectile instead of the normal spit; the mouth briefly changes shape while spitting. Implemented with GLFW, GLM, and a tiny helper shader (CSCI441::SimpleShader2), the program emphasizes low‑level control (VAOs, simple colors, and fundamental primitive types) while demonstrating animation, input handling, and hierarchical modeling.

Assignment 1 – Hero Banner: Build a 2D nameplate entirely from hand‑specified OpenGL vertex data. Each letter (B O R T) is assembled from simple triangles; the circular crest uses a triangle fan for the face, a reused fan for each eye, and a triangle strip arc for the mouth. An orthographic projection maps window pixels directly to coordinates, making layout straightforward. Per‑letter transforms (translation for O, rotation for R about its approximate center, and non‑uniform scale for T) demonstrate basic matrix operations via a simple push/pop stack. All geometry is stored in VAOs with a single color per shape, emphasizing low‑level control: just raw positions, colors, and three primitive types (GL_TRIANGLES, GL_TRIANGLE_FAN, GL_TRIANGLE_STRIP).

Lab 0 – Simple 2D Scene: Intro exercise focused on sending basic geometry to the GPU without helper libraries. The sun is a triangle fan (center + radial ring). Three mountains are individual filled triangles layered for depth. A tree is split into a rectangle trunk (two triangles) and a triangular canopy; that pair is instanced across the scene by applying translation matrices before each draw, reusing the same VAOs. Distinct primitive types were tested (GL_TRIANGLES for terrain, GL_TRIANGLE_FAN for the sun, GL_TRIANGLE_STRIP not yet needed here). An orthographic projection matches window pixels, keeping coordinates intuitive.
