OpenGL纹理故障与面孔

Question

我正在使用LWJGL创建一个简单的体素作为一些练习，作为一个中等简单的项目来熟悉Kotlin。

所以我已经将体素渲染下来了，除了渲染每个面部具有不同纹理的体素。

看起来好吧，直到我开始走动......然后：

如果有人需要整个回购，那就是here

至于相关的类，我不太确定什么是相关的，但是这里有生成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)







            // bottom face
            // bottom face (0, 1)
            GL11.glColor4f(colour.red.toFloat(), colour.green.toFloat(), colour.blue.toFloat(), colour.alpha.toFloat());
            GL11.glTexCoord2f(textures[0].x, textures[0].y + sheet.GetUniformSize());
            GL11.glVertex3f(x, y, z + size);

            GL11.glTexCoord2f(textures[2].x, textures[2].y + sheet.GetUniformSize());

编辑：经过一些测试后，我意识到当相机上面有问题的体素时，我只会得到奇怪的故障。我把类似的块放在别处，只露出侧面，从底部看，它们很好：

相机略高于挡板（问题会逐渐升高相机）： 块下方的相机：

编辑2：经过一些更多的测试后，事实证明问题是任何两种不同类型的块具有不同的纹理交互...所以它可能不是一个面对面的东西，但是而是一个面对面的互动的东西？我不知道。

编辑3：我决定尝试查明问题，因此我从代码中删除了glTexCoords2f（）调用。不幸的是，问题仍然存在：

Answer 1

所以

GLU.gluPerspective(67.0f, (width / height).toFloat(), 0.0001f, 1000.0f)

GLU.gluPerspective(67.0f, (width / height).toFloat(), 0.5f, 1000.0f)

怎么样？

基本上，减少最小视距，解决问题。
