Technologies

Leia

• Camera with Free Movement
• Fixed the camera in place
• Spun the world using time based movement
• Camera tracks the height of the player
• Complex Environment
• Includes multiple shape loading and rendering tehnology
• Randomly generated in spherical coordinates around the planet

Mattea

• Collision Detection
• Axis Aligned Bounding Boxes
• Collision detection between the character and objects spawned in the world
• Shadow Mapping
• Used a depth map to render shadows
• Applied rotation, scaling, and transformation to the shadows to render them on the spherical world
• Sophisticated HUD
• ImGui text rendering: placement and content
• Quad-based image rendering on a plane on the screen
• Integrated gameplay logic into the HUD

Bridget

• View Frustum Culling
• To overcome stationary camera, computed hypothetical positions of objects as if they had come into view
• Culled objects based on their hypothetical positions
• Rendering Techniques
• Implemented Cook Torrance BRDF with multiple lights and color scheme
• Added atmosphere effect that appears during zoom-out
• Made the world look pretty when you zoom out
• Object Heights
• Created rays from the origin towards every static object placed on the world
• Found heights for every static object based on ray/triangle intersections
• Updated character height during movement
