VIZA 665 : Digital Compositing
Spring 2019

Project 07: Visually Consistent compositing a single image of a 3D object into the digital image in 06 with global illumination First Review: Mar. 18
Submissions Due: Mar. 25
 

Overall Goal:

To learn handling scenes with transparent objects. In this particular project, you will learn how to add an articificial object into such scenes.

Synopsis:

This project is intended for you to deal with scenes that include mostly refractive surfaces. Use the assigned scene with transparent objects as a background.

Project Description:

You will composite an image of an artificial (i.e. CG) object into the given photograph of the recfractive scene using the work from previous poroject; i.e. image-space proxy geometry and an advanced Barycentric shader that represent materials.

Project Requirements:

  1. Be sure that the shading of the CG object is consistent with overall scene.
  2. Shadow of the object must look believable.
  3. In other words, shadow colors must match other shadows in the scene. Shadow shape must conform other shapes in the scene.
  4. Be sure reflection, refraction, Fresnel and Caustics looks acceptable.

Bonus:

  1. Move the light. The whole scene can be relighted. If your previous project is successful, this is trivial.


    Project Submission:

    Please upload your images to project website for critical review and class discussion.


    General Checklist for projects

    : For each project, we will check the following items.
    • Qualitative matching local camera position and orientation
    • Qualitative Consistent matching of artificial object with the lights and objects in the original image
      (each subject counted one and they depend on the problem.)
      • For diffuse parts of artificial object
        • Shading
        • Colors
        • Ambient illumination
        • Contact shadows
