Overall Goal:
To learn handling scenes with transparent objects. In this particular project, you
will learn
how to add an animated articificial object into such scenes.
Synopsis:
This project is intended
for you to deal with compositing animated artificial objects into the scenes
that include mostly refractive surfaces.
Use the assigned scene with transparent objects as a background.
Project Description:
You will composite an animation 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:
- Be sure that the shading of the CG object is consistent with overall scene.
- Shadow of the object must look believable.
- In other words,
shadow colors must match other shadows in the scene.
Shadow shape must conform other shapes in the scene.
- Be sure reflection, refraction, Fresnel and Caustics looks acceptable.
Bonus:
- Also move the light. The whole scene can be relighted. If your previous project is successful,
this is trivial.
- Turn your artificial object into emissive (i.e. light).
The whole scene will be relighted by moving. If your previous project is successful,
this could be 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
- Specular/glossy parts of artificial object
- Specular reflection of light
- Reflection of environment
- Transparent/translucent parts of artificial object
- Refraction of light
- Refraction of environment
- Shadow of artificial object
- Shadow colors
- Shadow shape
- Reflection of artificial object
- Shape of reflection
