2D Rasterizer

linearly interpolate colors on lines using DDA

fill a triangle using DDA

Goaraud fill a polygon

Goaraud fill a polygon

Fill given n-vertex polygon using even-odd rule

fill transparent shapes

Using the Digital Differential Analyzer (DDA) Algorithm to create images with gradient line color or gradient fill color.

3D Rasterizer

use a depth buffer to keep track of 3D objects' relative position

apply frustum technique

rotate 3D objects based on given axis and show depth relations

show depth relations

apply gradient fill to 3D objects

Use the Model/View transformations to perform rotation, scaling, translations and matrices. Next, clip planes, apply the projection matrix, perform frstum clipping and a viewport transformation. Finally, rasterize traingles into fragments and use depth buffer to determine the relative positions of 3D objects.

Raytracer

create shadows on plane

create shadows for overlapping objects

render light source from inside a sphere

render complicated shadows with objects

render complicated shadows with objects

render multiple suns sources

Use ray emission and ray collision to generate 3D objects. Then, use Lambert's law to illuminate objects and create shadows.

Animation

animate changing shapes

animate multiple cubes

animate changing shapes

create shadows for overlapping objects

depict obejects based on their relative relations to parents

use Euler to depict object orientations

Render animations with a combination of a scene graph and time-varying parameters.
