      net.jinx.video.model.QuadStrip

public final class QuadStrip
extends MeshElement

MeshElement implementation that uses OpenGL's GL_QUAD_STRIP drawing mode to draw quadrilateral shapes (quads). Vertices come in pairs. Each quad is formed from the two most recent pairs.

API Stability: Stable.

Constructor Summary

QuadStrip(float[][] vertices)
Constructs a QuadStrip with the given vertex array.

Method Summary

int	draw(Context opt, float[][] normals, float[][] texCoord, Coloration coloration, int offset) Draws the mesh, using the given array of Materials.
Face[]	getFaces() Provides an array of all the Faces formed by this MeshElement.

Constructor Detail

QuadStrip

public QuadStrip(float[][] vertices)

Constructs a QuadStrip with the given vertex array.

Parameters:

vertices - the vertex array.

Method Detail

getFaces

public Face[] getFaces()

Description copied from class: MeshElement

Provides an array of all the Faces formed by this MeshElement. This is used to calculate per-vertex normals for lighting.

Specified by:

getFaces in class MeshElement

Returns:

the array of Face objects.

draw

public int draw(Context opt,
                float[][] normals,
                float[][] texCoord,
                Coloration coloration,
                int offset)

Description copied from class: MeshElement

Draws the mesh, using the given array of Materials. One Material will be used per vertex, unless there is only one, in which case the same color will be used for each vertex. The offset into the array will be incremented with each vertex and then returned once the Mesh has finished drawing.

Specified by:

draw in class MeshElement

Parameters:

opt - the rendering options to use.

normals - vectors in a vertex array for per-vertex normals. If null, this indicates that per-face normals should be used instead.

coloration - the Coloration object to use to color the vertices.

offset - the index into normal array to start at. This is also the current vertex number.

Returns:

the index of the next normal to use, once this method has completed. This is also the number of the next vertex.
