LECTURES
Week 9
-1. 3D Object and VFX Integration The game engine acts as the core real-time integration platform, unifying all assets, interactive logic and rendering effects.
1.Layered VR object construction logicFunctional VR interactive objects are built in layers, requiring three core components: physical collision boundaries, movement animation rules, and complete interactive trigger logic to realize grabbing, touching and other user operations.
2. VFX serves as spatial feedback for usersAll visual effects in VR need to link to user’s body movements and operations: they can render scene atmosphere and guide the user’s sight and operation focus within the virtual space.
3. Performance constraint for all effectsVisual effects cannot be made without limits. Creators must balance visual quality and running frame rate, optimize effect resources to guarantee smooth operation and avoid dizziness or discomfort for VR users.
2. Environmental and Atmospheric Effects
This part focuses on techniques to enrich the immersive sense of the whole VR scene, including background, particle, light and fog systems, with optimization as a constant requirement.
1.360° panoramic background
It wraps users in a complete virtual environment (sky, horizon, outdoor scenery, indoor spaces). Its limitation is that it only serves as distant backdrop, and cannot be walked through or interacted with as real 3D geometry.
2.Particle systems to activate scene vitality
Micro dynamic particle effects including dust, sparks, rain, snow, falling leaves are used to inject dynamic sense, set emotional tone and enrich atmosphere of static scenes.
3.Lighting & fog for depth and mood shaping
Collocation of light sources, shadows, fog and sky color can strengthen space depth and layered sense, and establish unique emotional atmosphere of the virtual scene.
4.Uniform optimization rule for atmosphere effects
Rich atmospheric effects will bring heavy rendering load; all particle, light and fog resources need lightweight processing to ensure stable running of VR headsets.
3. Final Compositing, Optimization and Output Different from traditional flat video rendering, VR projects operate in real-time inside head-mounted devices, with special standards for synthesis, optimization and release output.
1.Characteristics of live-running VR scenes
VR works do not export static videos. All elements including 3D models, lighting, VFX, audio, interactive UI and trigger logic operate synchronously in real time when users wear the headset.
2.Core optimization targets
High-poly models, a large number of transparent particle effects, redundant light sources and complex shaders are the main sources of performance loss. Creators need to simplify these resources to maintain smooth frame rate and user comfort.
3.VR output form: standalone application
The final deliverable of a VR project is a complete application packaged for designated VR hardware devices and corresponding operating platforms, rather than video files or editable engineering files.
4.Final acceptance standard
A project is only completed after passing actual headset testing: stable frame rate, fully functional controller operation, and natural, fatigue-free interactive experience for users.
