Constructor Detail

GoVertex

public GoVertex(int vertexNumber)

Abstract constructor for primitive vertex data (see render).

Equivalent to:

GoVertex(vertexNumber, Go.NONE)

GoVertex

public GoVertex(int vertexNumber,
                int flags)

Abstract constructor for primitive vertex data (see render).

The number of vertices to be created is indicated with vertexNumber.

Color and normal information can also be included for each vertex as indicated with flags.

Possible values for flags are any or'ed combination of:

COLOR

Include per vertex color information. If this flag is not set, the current color (see color) will be used at each vertex instead.

NORMAL

Include per vertex normal information to apply lighting (see light(number, enabled) and light(number, light) for information on enabling and setting up lights).

AUTO_NORMAL

Automatically calculate per vertex normals to apply lighting (see light(number, enabled) and light(number, light) for information on enabling and setting up lights). This will cause flat shading and is mostly used for prototyping. If smoother shading is desired, user defined normals should be supplied (i.e. use the Go.NORMAL flag rather than this Go.AUTO_NORMAL flag).

This flag is only recognized with GoTriangles, GoTriangleStrip and GoTriangleFan primitives.

Go.NONE

No per vertex color or normal information.

Method Detail

vertexNumber

public int vertexNumber()

Returns the number of vertices included in this set.

flags

public int flags()

Returns the flags' bits indicating the inclusion/absence of color and normal information.

The return value can be used to check for the following:

Go.COLOR

If included then (flags() & COLOR) > 0 must yield true.

Go.NORMAL

If included then (flags() & NORMAL) > 0 must yield true.

Go.AUTO_NORMAL

If included then (flags() & AUTO_NORMAL) > 0 must yield true.

append

public boolean append(int vertexNumber)
