DS Opera SDK v3.0
Easily add useful functionality to your games for the Nintendo DSi Browser.

Classes:
1. Drawing - Polygon mesh plotting to a canvas
1. ThreeD - 3D matrix math for triangles and hidden surfaces

Drawing

• null = clear( x1,y1, x2,y2 )
  Erases all contents of the given canvas section
• null = drawCircle( x,y,rad, fillFlags )
  Draws a filled or stroked circle
• null = drawLine( x1,y1, x2,y2 )
  Draws a line segment
• null = drawRectangle( x1,y1, x2,y2, fillFlags )
  Draws a rectangle
• null = drawScene( Array[ ][x1,y1, x2,y2, x3,y3, r,g,b], fillFlags )
  Draws a scene of triangles
• null = initialize( Canvas )
  Sets the current canvas object for drawing
• null = setFillColor( r,g,b )
  Sets the RGB value of all upcoming fills
• null = setLineColor( r,g,b )
  Sets the RGB value of all upcoming lines
• Constants
  fillFlags: WIREFRAME,SHADE

ThreeD

• null = backface( )
  Removes hidden triangles from the buffered object
• null = explode( x,y,z )
  Shifts the buffered triangles along their normals a given distance
• Array[ ][x1,y1,z1, x2,y2,z2, x3,y3,z3, r,g,b] = getPoints( )
  Retrieves the buffered mesh
• Array[ ][x1, y1, x2, y2, x3, y3, r, g, b] = getTranslation( )
  Retrieves the 2D translation of the buffered triangles for display
• null = loadMesh( meshString )
  Loads a pre-made 3D mesh into the triangle buffer
• null = move( x,y,z )
  Shifts the buffered triangles
• null = rotate( anglex, angley, anglez )
  Rotates the buffered triangles
• null = scale( x,y,z )
  Zooms the buffered triangles by a given factor
• null = setCenter( x,y )
  Sets the perspective center for 3D to 2D translation
• null = setLight( x,y,z )
  Sets the current light source for shading
• null = setPoints( Array[ ][x1,y1,z1, x2,y2,z2, x3,y3,z3, r,g,b] )
  Places an array of polygons into the buffer
• null = shade( )
  Flat shades the buffered triangles based on SetLight()
• null = zSort( )
  Orders the buffered polygons for proper display
• Constants
  none
