Org Or Inorg? Atmospheric Carbon Controls That Initiated The Late Paleozoic Ice Age 326mya, Paco Defrancis Apr 2015

Org Or Inorg? Atmospheric Carbon Controls That Initiated The Late Paleozoic Ice Age 326mya, Paco Defrancis

CLAS: Colby Liberal Arts Symposium

The Late Paleozoic Ice Age (LPIA) was a major global icehouse that initiated in the Mississippian (326 million years ago; ma) and lasted through the Early Permian (267ma). An ice sheet nucleated in southern Gondwana near the South Pole, which either paleogeography (positioning of paleocontinents) or atmospheric concentration of the greenhouse gas CO2 controlled. In this paper I accept recent findings that prove atmospheric pCO2 and not paleogeography forced global cooling that resulted in the nucleation of Gondwanan ice sheets that defined the LPIA. There remains no broad consensus of what caused pCO2 lowering in the Mississippian. Organic carbon found …


An Exploration Into Computer Graphics: L-Systems And A Non-Photorealistic Filter, Victoria Edwards Apr 2015

An Exploration Into Computer Graphics: L-Systems And A Non-Photorealistic Filter, Victoria Edwards

CLAS: Colby Liberal Arts Symposium

This past fall I worked on developing a graphics pipeline. I implemented a handful of graphics algorithms that allowed me to render creative scenes. This semester we explored the world of computer graphics by doing an in-depth study of different areas in the field. To do this we read critical SIGGRAPH papers on the subjects. SIGGRAPH is the publication forum for computer graphics and it maps the last forty years of research in the computer graphics world. This semester I have decided to focused on the photorealistic method of creating L-Systems and a non-photo realistic image filter.


Exploring Computer Graphics: Photorealistic And Non-Photorealistic Rendering, Brittany Chin Apr 2015

Exploring Computer Graphics: Photorealistic And Non-Photorealistic Rendering, Brittany Chin

CLAS: Colby Liberal Arts Symposium

Over the course of the year, the Advanced Computer Graphics course has explored a variety of image rendering techniques starting with the basic filling of polygons, and working all the way up to non-photorealistic rendering techniques. I have implemented a variety of these techniques in projects which demonstrate the growth and advancements of graphics over time. The implementations that are featured are an interactive tile game, a curve editor, a ray-tracer, and a non-photorealistic project. The capabilities of computer graphics are seemingly endless, and it is getting easier and easier to model the real world in synthetic systems. Where will …

3d Model Generation From Flat Images And Other Pretty Pictures, Matthew Levine Apr 2015

3d Model Generation From Flat Images And Other Pretty Pictures, Matthew Levine

CLAS: Colby Liberal Arts Symposium

We present a novel method of generating 3D models from 2D images using neural network techniques. We also show a custom implementation of a global illumination model natively integrated into Python's standard 2D image library (with a fast C backend).


Trees And Non-Photorealistic Images, Christopher Burnham Apr 2015

Trees And Non-Photorealistic Images, Christopher Burnham

CLAS: Colby Liberal Arts Symposium

Showing of a graphics system with some trees and non-photorealistic images.


A Look Into Graphics Engines And Non-Photorealistic Rendering, Margaux Leblanc Apr 2015

A Look Into Graphics Engines And Non-Photorealistic Rendering, Margaux Leblanc

CLAS: Colby Liberal Arts Symposium

Throughout the year I have created a graphics pipeline that can render both photorealistic and non-photorealistic images. It all starts with defining what a pixel is and building from there. For instance, an image is a collection of pixels, a color is just three numbers (red, green, and blue values), a line is coloring certain pixels with such a color based on Bresenham's line algorithm and so on. My graphics engine can draw and shade points, lines, polylines, and polygons according to different algorithms. Using these basic shapes I can create photorealistic images of L-systems and non-photorealistic images of paintbrush …


Computer Graphics Presentation, Itrat Akhter Apr 2015

Computer Graphics Presentation, Itrat Akhter

CLAS: Colby Liberal Arts Symposium

The aim of this poster presentation is to display the works that I did over two semester of computer graphics classes. As such, I will give a brief glimpse of the methods and images involving fractals, bezier curves and surfaces, hierarchical modeling, shading and lighting, particle systems and others.
