我正在使用 LWJGL 创建一个简单的体素事物作为一些练习，作为一个适度简单的项目来熟悉Kotlin。
所以我已经降低了体素渲染，除了渲染每个面具有不同纹理的体素。
看起来不错，直到我开始四处走动......然后：
如果有人需要整个回购，它就在这里
至于相关的类，我不太确定什么是相关的，但这是生成glVertex3f和glTexture2f的东西：
public class Shape
{
class object
{
public fun CreateCube(x: Float, y: Float, z: Float, colour: ColourRGBA, tex: MutableList<TextureCoords>, size: Float)
{
val sheet: Spritesheet = Main.Instance!!.blocksprites
var textures: MutableList<TextureCoords> = arrayListOf()
if (tex.size == 1)
{
for (i in 0 .. 5)
textures.add(tex[0])
}
else
textures.addAll(tex)

编辑：经过更多测试，我意识到只有当相机位于相关体素上方时才会出现奇怪的故障。我将类似的块放在其他地方，只暴露侧面，从底部看时它们很好：
相机略高于方块（相机越远，问题就会升级）：
相机低于方块：
编辑 2：经过更多测试，事实证明问题在于具有不同纹理的任何两种不同类型的块相互作用......所以它可能不是每个人脸的事情，而是人脸互动的事情？我不知道。
编辑 3：我决定尝试查明问题，所以我从我的代码中删除了 glTexCoords2f() 调用。不幸的是，问题仍然存在：
