LibGdx GLES2.0立方体纹理像素拉伸 [英] LibGdx GLES2.0 cube texel stretching

问题描述

我已经几年编程在Windows / SDL OpenGL和我能够做相当多的先进的东西吧。

I've been programming OpenGL on Windows/SDL for a few years and am able to do quite a lot of advanced things with it.

我已经切换到Android和libgdx在过去的几天里试图把一个简单的演示起来，只是一个旋转的立方体。

I've switched over to Android and libgdx and over the past few days have tried to put a simple demo together, just a spinning cube.

使用libgdx的 ObjLoader 和网​​类，我装在搅拌机出口（与法线和UV COORDS立方体网），并尝试应用纹理，并将其绘制一个立方体，但似乎只使用一个纹理像素从纹理以覆盖整个模型

Using libgdx's ObjLoader and Mesh classes, I loaded a cube mesh exported from blender(with normals and uv coords), and tried to apply a texture, and it draws a cube, but seems to only uses one texel from the texture to cover the whole model.

我仔细检查过的纹理坐标，甚至手$ C $光盘的具体坐标，以测试飞机，同样的事情正在发生。

I've double checked the texture coordinates and even hand coded a plane with specific coordinates to test, and the same thing is happening.

这是顶点着色器：

attribute vec4 a_position;
attribute vec3 a_normal;
attribute vec2 a_texCoord;

uniform mat4 mvp;

varying vec3 outNormal;
varying vec2 outTexcd;

void main(){
    outNormal = a_normal;
    outTexcd = a_texCoord;
    gl_Position = mvp * a_position;
}

和片段着色器：

precision highp float;

varying vec3 outNormal;
varying vec2 outTexcd;
uniform sampler2D tex;

void main(){
    vec3 norms = outNormal;
    gl_FragColor = texture2D(tex,outTexcd);
}

但我不认为这是问题所在。或者，也许是这样，我不知道。

But I don't think that's where the problem lies. Or maybe it does, I'm not sure.

本来不想堵塞这个问题太多这样的主要来源是在这里（引擎收录）：主要来源

Didn't want to clog up this question too much so the main source is here(pastebin): Main Source

如果这是一个不好的问题，请让我知道，这是我的第一个。

If this is a bad question please let me know, It's my first one.

推荐答案

与图片玩我找到了答案。

Playing with images I found the answer.

使用当时32位巴纽RGBA8888，但没有告诉libgdx这一点。

Was using a 32 bit .png RGBA8888, but not telling libgdx that.

切换到取图像RGBA8888的：

Switched to take in the image as RGBA8888:

T =新的纹理（Gdx.files.internal（图像/ r3.png），Format.RGBA8888，真实）;

我稍感不好意思，对不起所有。

I feel slightly sheepish, sorry all.

编辑：
奇怪的是，没有透明度虽然...

Strangely, no transparency though...
