About
A sweet Bezier surface converter.
Authors: Alec Mouri (cs184-cq) and Austin Chen (cs184-cn)
This program is written in Java, and was developed against the Windows and Android platforms.
Features
- Conversion from Bezier patches to Polygon representations
Rendering of objects using OpenGL
Toggling of Uniform and Adaptive Tessellation
Toggling between flat and smooth shading
Input and output of .obj files
Toggling between filled, wireframe, and hidden-line mode
Rotation and Translation of objects
Loading and control of multiple objects
Vertex color shading of Gaussian curvatures
An Android demo
Command line arguments:
The first argument is always the input file and the second argument is always a subdivision parameter. Additional arguments:
-
-a-- Specifies the use of adaptive tessellation. -
-o [file_name]-- Specifies the output of an .obj file to file_name
Controls:
-
s-- Toggles between flat and smooth shading -
w-- Toggles between wireframe and filled mode -
h-- Toggles between hidden-line and filled mode -
Arrow keys-- Rotates the selected object -
Shift + arrow keys-- Translates the selected object -
+/--- Zooms in and out -
v-- Selects the next object -
c-- Toggles coloring of Gaussian curvature
Scene format:
The .scene file format contains a list of files to be rendered. Each file corresponds to a separate object. Before each file is specified, translations and rotations with respect to the origin must be specified:
Example (test.scene):
translate 0 0 -10 # Translates Teapot1 -10 along the z-axis
rotate 0 0 0 # No rotation specified for Teapot1
teapot.bez # Defines Teapot1
translate .5 .5 -15 # Translates Teapot2 .5 along the x-axis, .5 along the y-axis, -15 along the z-axis,
rotate 90 90 90 # Rotate Teapot2 by 90 degress along each axis.
teapot.bez # Defines Teapot2
