LTU-labs

Almost everything I have bashed on the keyboard the during game development studies at LTU.
I continue working on this repository, refining the code and adding ⚠new projects.

OpenGL

Physics Engine

• SAT
• Clipping - multiple contacts
• BAUMGARTE + positional penetration correction
• Impulse based collision response
• Different integration methods.

Graphics

• Deferred Shading
• VSM (Forward)
• ⚠VSM (Deferred) (PCF Point light shadows)
• Per-pixel picking
• Geometry Subdivision
• Scene graph
• Double & Single Precision Math lib
• ⚠Particles
• ⚠Soft Particles
• ⚠HDR
• ⚠Bloom
• ⚠Normal mapping
• ⚠Specular maps
• ⚠PBR with shadows

Network

• Socket programming for Windows & Linux
• Cross-Platform communication between Windows & Linux
• Multicast
• UDP/TCP
• JAVA, C, C++

AI

• State Machine project simulating life of "sims"
• Pathfinding algorithms, performance and usecase analysis

Key-bindings for OpenGL projects

• 0-9 - Changing scenes(number of scenes may vary for each project)
• WASD - Camera movement.
• Backspace - Enable physics for lights(deferred project only)
• LShift - Descend
• Spacebar - Ascend
• LAlt - Toggle lock/unlock mouse in window.
• Arrows - Move (last selected) object
• NUM+ - Increase time-step
• NUM- - Decrease time-step
• T - Reset time-step (60Hz)
• P - Pause
• O - Toggle drawing of bounding boxes.
• L - Toggle drawing of lines.
• F5 - Toggle drawing of contact points, collision normals, and clip planes.
• TAB - Toggle wireframe/shaded drawing modes.
• E - Spawn a cube.
• LCtrl+S - Save the last object added to the scene, mostly for saving the subdivided mesh back to obj file.
