Usage

From source file:TexCoordTest.java

void createAppearance(double yMaxHeight) {
    // create an Appearance and assign a Material
    m_Appearance = new Appearance();
    m_Appearance.setCapability(Appearance.ALLOW_TEXGEN_WRITE);

    Color3f black = new Color3f(0, 0.2f, 0);
    Color3f objColor = new Color3f(0.1f, 0.7f, 0.2f);
    m_Appearance.setMaterial(new Material(objColor, black, objColor, black, 0.8f));

    // load the texture image
    TextureLoader texLoader = new TextureLoader("stripes.gif", Texture.RGB, this);

    // clamp the coordinates in the S dimension, that way they
    // will not wrap when the calculated texture coordinate falls outside
    // the range 0 to 1. When the texture coordinate is outside this range
    // no texture coordinate will be used
    Texture tex = texLoader.getTexture();
    tex.setBoundaryModeS(Texture.CLAMP);

    // assign the texute image to the appearance
    m_Appearance.setTexture(tex);/*from w ww.jav a2  s .c o m*/

    // create the TexCoordGeneration object.
    // we are only using 1D texture coordinates (S) - texture coordinates
    // are calculated from a vertex's distance from the Y = 0 plane
    // the 4th parameter to the Vector4f is the distance in *texture
    // coordinates*
    // that we shift the texture coordinates by (i.e. Y = 0 corresponds to S
    // = 0.5)
    TexCoordGeneration texGen = new TexCoordGeneration(TexCoordGeneration.OBJECT_LINEAR,
            TexCoordGeneration.TEXTURE_COORDINATE_2, new Vector4f(0, (float) (1.0 / (2 * yMaxHeight)), 0, 0.5f),
            new Vector4f(0, 0, 0, 0), new Vector4f(0, 0, 0, 0));

    // create our "non-live" TexCoordGeneration object so we
    // can update the "genMode" parameter after we go live.
    m_TexGen = (TexCoordGeneration) texGen.cloneNodeComponent(true);

    // assign the TexCoordGeneration to the Appearance
    m_Appearance.setTexCoordGeneration(texGen);

    // we just glue the texture image to the surface, we are not
    // blending or modulating the texture image based on material
    // attributes. You can experiment with MODULATE or BLEND.
    TextureAttributes texAttribs = new TextureAttributes();
    texAttribs.setTextureMode(TextureAttributes.DECAL);
    m_Appearance.setTextureAttributes(texAttribs);
