A Dynamic Optix Playground

My CSC 473 Final Project

A realtime app that lets you play around with
Raytracing in a dynamic Optix sandbox

Technology

Features

• Powered using NVIDIA OptiX 7.2 with base code from NVIDIA’s Optix 7 sample project 'intro_denoiser' (Github Repo)


• Added ability to dynamically generate instances of cubes, spheres, or planes based on the position and direction of the camera


• Added ability to track all instances in the scene and kept track of their position/scale/rotation to allow for real-time adjustments of the objects in the scene


• Added “Create/Spawning” modes that use reference objects to guide the placement of objects

Technology

Manual

Custom Controls

• SPACE = Spawn objects if a 'Spawn Mode' is active


• (Activate 'Spawn Mode' using the GUI display)




Controls from Base Project



• Left Mouse Button + Drag = Orbit (around center of interest)


• Middle Mouse Button + Drag = Pan (The mouse ratio field in the GUI defines how many pixels is one unit.)


• Right Mouse Button + Drag = Dolly (nearest distance limited to center of interest)


• Mouse Wheel = Zoom (1 - 179 degrees field of view possible)


• ~ = Toggle GUI display on/off






Video Demo







Sample Images

(All set up within the app)



As seen above, my original inspiration for the project was to try to produce a mirror-based puzzle game
where players could dynamically place/move Optix-powered mirrors to achieve a goal
(like by making the pink ball visible in the green mirror)

Also, thank you, Professor Zoë Wood, for teaching this class!
I really enjoyed it!
