# Textured Quad at exact location?

Lets say you want a simple rectangle [(x0, y0, z0); (x1, y1, z1); (x2, y2, z2); (x0+x2-x1, y0+y2-y1, z0+z2-z1)],

with texture coordinates (0.0, 0.0, 0.5, 0.5), how would one create that in JM3?

In Java3D, i’d simply do a

[java] public static Shape3D texturedPlane(Point3f[] pfa, TexCoord2f[] qfa,

Texture2D tex, boolean fMaterial)

{

NormalGenerator ng = new NormalGenerator();

return texturedPlane(pfa, qfa, tex, fMaterial, gi, ng);

};

public static Shape3D texturedPlane(Point3f[] pfa, TexCoord2f[] qfa,

Texture2D tex, boolean fMaterial, GeometryInfo gi, NormalGenerator ng)

{

if (tex == null)

return null;

Appearance appear = new Appearance();

);

if (fMaterial)

{

Material mat = new Material();

mat.setAmbientColor(new Color3f(0.1f,0.1f,0.1f));

mat.setDiffuseColor(new Color3f(0.3f,0.3f,0.3f));

mat.setSpecularColor(new Color3f(0.01f,0.01f,0.009f));

mat.setLightingEnable(true);

mat.setShininess(0.0f);

appear.setMaterial(mat);

}

if (tex.getFormat() == Texture2D.RGBA)

{

TransparencyAttributes transAttr = new TransparencyAttributes();

transAttr.setTransparency(0.0f);

transAttr.setTransparencyMode( TransparencyAttributes.BLENDED );

appear.setTransparencyAttributes(transAttr);

}

TextureAttributes textAttr = new TextureAttributes();

textAttr.setTextureBlendColor(0.01f, 0.01f, 0.01f, 0.5f);

textAttr.setTextureMode(TextureAttributes.MODULATE);

appear.setTextureAttributes(textAttr);

gi.setCoordinates(pfa);

ng.generateNormals(gi);

plane.setNormals(0, gi.getNormals());

appear.setTexture(tex);

plane.setCoordinates(0,pfa);

plane.setTextureCoordinates(0, 0, qfa);

Shape3D shape = new Shape3D(plane);

shape.setAppearance(appear);

return shape;

};

[/java]

Lol, “simply do a” xD

Have you seen this: https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:advanced:custom_meshes ?

Ah, must have skipped that… BTW, if you substract the material and color blending, it is /almost/ simple ;-}

I posted a RFC/contribution here.

There is btw an error in the wiki’s article – the texture coordinates are messed up.

[java]Vector2f[] texCoord = new Vector2f[4];
texCoord[0] = new Vector2f(0,0);
texCoord[1] = new Vector2f(1,0);
texCoord[2] = new Vector2f(0,1);
texCoord[3] = new Vector2f(1,1);[/java]

see, what i mean?

You can edit the wiki with the wiki entry in the black bar menu on top.

lol Ok, i just noticed that bar for the first time;-)
