我在 java3D 和 stackoverflow 上都是新手。我的问题是我尝试将 BufferedImage 纹理添加到矩形,但它没有出现。我将 BufferedImage 保存到一个文件中,所以我确定它不是空的。“bi”是缓冲图像。我能找到的关于 java3D 的任何东西似乎都已经过时了。评论是关于它上面的命令,而不是下面的。
QuadArray alap = new QuadArray(4, QuadArray.COORDINATES | GeometryArray.TEXTURE_COORDINATE_2);
// [...] setting coordinates for the polygon (rectangle)
Appearance alapAppearance = new Appearance();
PolygonAttributes alapPa = new PolygonAttributes();
alapAppearance.setPolygonAttributes(alapPa);
alap.setTextureCoordinate (0, 0, new TexCoord2f(0.0f,0.0f));
alap.setTextureCoordinate (0, 1, new TexCoord2f(1.0f,0.0f));
alap.setTextureCoordinate (0, 2, new TexCoord2f(1.0f,1.0f));
alap.setTextureCoordinate (0, 3, new TexCoord2f(0.0f,1.0f));
//tryed in different order
TextureAttributes texAttr = new TextureAttributes();
texAttr.setTextureMode(TextureAttributes.REPLACE);
TextureLoader loader = new TextureLoader(bi, TextureLoader.ALLOW_NON_POWER_OF_TWO);
//Tryed with "RGB" flag too (as second parameter).
Texture t1 = loader.getTexture();
t1.setBoundaryModeS(Texture.CLAMP_TO_EDGE);
t1.setBoundaryModeT(Texture.CLAMP_TO_EDGE);
alapAppearance.setCapability(Appearance.ALLOW_TEXTURE_WRITE);
alapAppearance.setCapability(Appearance.ALLOW_TEXTURE_ATTRIBUTES_WRITE);
//I don't think it's really needed, but can't hurt I quess.
alapAppearance.setTextureAttributes(texAttr);
alapAppearance.setTexture(t1);
tfg.addChild(new Shape3D(alap, alapAppearance));
//tfg = transformGroup
