Marie Jarrell; The King's Treasure; Due Tues. 4-23-2013

Description:

For this assignment we textured the "Challenge #19: The King's Treasure" scene from the 3Drender.com challenge website (http://www.3drender.com/challenges/). Including reflection, refraction, caustics, and bump mapping on appropriate objects, with mental ray. Concentrating on texturing the scene using techniques that would result in realistic and interesting shading and texturing.

Problems and Solutions:

It took me a great deal of time to work out how to get the caustics working and making the gems look nice. I used maya's mia material shaders to get better metal shaders and found a copper tutorial in the DPA809 folder which contained a beautiful fabric shader which I manipulated for the crown fabric and gave me a better understanding on what attributes affect how a metal looks. This helped me a great deal when I was manipulating the coins. For some reason I couldn't get my shadows to wok the way I wanted however, I found a tutorial on line on how to composite using photoshop. This allowed me to try my hand at using ambient occlusion.

Marie Jarrell; Fruit Bowl; Due Tues. 4-2-2013

Description:

For this assignment we textured the "Challenge #1: Fruit Bowl" scene from the 3Drender.com challenge website (http://www.3drender.com/challenges/). Concentrating on texturing the scene using techniques that would result in realistic and interesting shading and texturing. Also, we were to implement good lighting for the objects in the scene.

Problems and Solutions:

The biggest problems I faced were all based around lighting, either giving the fruits definition through lighting or dealing with shadows. For example, while working on the orange I had to find a way of lighting it and revealing the shape and dimensions of the fruit without disconnecting it from the plate. The orange required several special lights to create shadows and bounce back light from the plate to keep it from being too dark.

Working with file textures didn't cause me too much pain as I was able to use several techniques from class such as using layered shaders, and editing UVs to get the textures and gradations I wanted. However, there was a constant struggle to get these textures to work with the shader type, and lighting to remove the fruits original metallic appearance. I was able to do this really well with the bananas, but once again the orange, and even the grapes turned out to be really difficult to work with. For the orange I tried to solve this with the lights and for the grapes I experimented with the attributes and tried to use translucency to get a more organic looking piece of fruit.

Marie Jarrell; Architectural Lighting; Due Tues. 3-5-2013

Description:

For this assignment we textured the "Challenge #17: Natural History" scene from the 3Drender.com challenge website (http://www.3drender.com/challenges/). Concentrating on creating a realistic environment, using lighting methods discussed in class.

Problems and Solutions:

This was a large disorganized file, every stair step, colum, block or decoration was its own geometry and the overall size of the file made work slow and prone to crashing. I first had to spend a great deal of time grouping and combining items, deleting items that were not visible in my scene, and generally just trying to decrease the file size.

Still no matter what I did I could not load texture files on anything but my own laptop. The walls and columns of the museum refused to load texture files no matter what I did. So, I simply used the texture supplied by the file and manipulated the attributes of that texture.

Finally for the floor, I liked the texture but was seeing some pixelation in my renders. 

To fix this I increased the number of pixels in the image  and the resolution of the file.

Advanced Raytracer

Description:

For this project, we extended the intermediate ray tracer implemented for Project 2.

My ray tracer includes: reflection, refraction, and anti-aliasing via super-sampling.
