Android 非常大的背景纹理

Android 非常大的背景纹理,android,opengl-es,libgdx,textures,Android,Opengl Es,Libgdx,Textures,对于我正在开发的游戏,我必须使用大背景图像。这些图像约为5000x3000。当尝试将其显示为单个纹理时,我会在GWT和Android中看到黑匣子。我创建了一个将图像分割为纹理网格的类: public class LargeImage extends LoadableGroup { private boolean smooth=true; public String filename; private int trueWidth,trueHeight; private ArrayList<I

也许对你有帮助。如果你不使用更多,我发现了问题。我忘了处理1x1背景填充。我忘了我使用这个类通过发送Pixmap来创建1x1图像。1x1被转换为512x512,并在各个级别累积,直到达到极限。我在它正在被创建,并修复了整个问题

我还更新了平铺生成器,使其使用所需的最小纹理大小,并提高到GL_MAX_texture_size。这样,1x1图像实际上是1x1,5000x3000平铺更少,具体取决于图形硬件。以下是新代码:
