Image Based Lighting
This project is a combination of the final project of CS22 3D Modeling and the CS89 Computational Photography course. It’s an implementation of Deb98, Rendering synthetic objects into real scenes.
Take a photo for the chrome ball that is placed on the desk, and a photo for the desk as the background.
Generate environment mapping
Calculate the environment mapping using the ball’s image.
Make local scene inside Maya
For this scene, I made a plane with a specular material for the character to walk on.
Inorder to perform differential rendering, we need render three different passes. 1. Render the combination of the local scene and the object we want to place. 2. The other is a mask of the object, so we don’t perform the differential operation on those pixels. 3. The local scene itself without the object
The last step is using those three rendered passes to combine the result.
