Method Detail

addTriangle

private void addTriangle(int x1,
                         int y1,
                         int z1,
                         int x2,
                         int y2,
                         int z2,
                         int x3,
                         int y3,
                         int z3,
                         int colorCode)

Splits the triangle defined by the specified values into horizontal lines and creates Edge-objects with the calculated values. The Edge-objects are stored in the vector of the scanline-Vector at the corresponding position.

Parameters:

x1 - x-coordinate of point 1

y1 - y-coordinate of point 1

x2 - x-coordinate of point 2

y2 - y-coordinate of point 2

x3 - x-coordinate of point 3

y3 - y-coordinate of point 3

colorCode - color the triangle should be drawn with

render

public void render(Graphics g)

Description copied from interface: Renderer

This method starts the render process. The image data is written to the specified graphics object.

Specified by:

render in interface Renderer

Parameters:

g - Graphics object the image should be rendered to

toConsole

public void toConsole()

Description copied from interface: Debugable

Prints the contents of the object to the Java console. How the information will be displayed depends on what data the object contains. Depending on structure and contents every implementation of this function produces a different result on the console.

Specified by:

toConsole in interface Debugable

toConsole

public void toConsole(java.lang.String msgString)

Description copied from interface: Debugable

Prints the contents of the object to the Java console together with an information string. How the information will be displayed depends on what data the object contains. Depending on structure and contents every implementation of this function produces a different result on the console.

Specified by:
