在Quads OpenGL上重复纹理 [英] Texture repeating on quads OpenGL

问题描述

我正在编写体素引擎，此刻 我正在研究块渲染系统，但是有问题. 似乎在四边形上重复了纹理.

  

草块底部有一条绿线，我不知道为什么.

这是OpenGL渲染代码:

Texture texture = TextureManager.getTexture(block.getTextureNameForSide(Direction.UP));
texture.bind();
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2d(0, 0); GL11.glVertex3f(0, 1, 0);
GL11.glTexCoord2d(1, 0); GL11.glVertex3f(0, 1, 1);
GL11.glTexCoord2d(1, 1); GL11.glVertex3f(1, 1, 1);
GL11.glTexCoord2d(0, 1); GL11.glVertex3f(1, 1, 0);
GL11.glEnd();

这是OpenGL设置:

GL11.glEnable(GL11.GL_TEXTURE_2D);
GL11.glShadeModel(GL11.GL_SMOOTH);
GL11.glClearColor(0.1F, 0.4F, 0.6F, 0F);
GL11.glClearDepth(1F);
GL11.glEnable(GL11.GL_DEPTH_TEST);
GL11.glDepthFunc(GL11.GL_LEQUAL);
GL11.glHint(GL11.GL_PERSPECTIVE_CORRECTION_HINT, GL11.GL_NICEST);
GL11.glCullFace(GL11.GL_BACK);
GL11.glEnable(GL11.GL_CULL_FACE);

解决方案

确保将GL_TEXTURE_WRAP_S和GL_TEXTURE_WRAP_T设置为GL_CLAMP_TO_EDGE.

I am writing a voxel engine and at the moment I am working on the Chunk-Rendering-System but I have a problem. It seems that the textures were repeated on the quads.

  

There is this green line at the bottom of the grass blocks and I don't know why.

This is the OpenGL-Render-Code:

Texture texture = TextureManager.getTexture(block.getTextureNameForSide(Direction.UP));
texture.bind();
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2d(0, 0); GL11.glVertex3f(0, 1, 0);
GL11.glTexCoord2d(1, 0); GL11.glVertex3f(0, 1, 1);
GL11.glTexCoord2d(1, 1); GL11.glVertex3f(1, 1, 1);
GL11.glTexCoord2d(0, 1); GL11.glVertex3f(1, 1, 0);
GL11.glEnd();

And here is the OpenGL-Setup:

GL11.glEnable(GL11.GL_TEXTURE_2D);
GL11.glShadeModel(GL11.GL_SMOOTH);
GL11.glClearColor(0.1F, 0.4F, 0.6F, 0F);
GL11.glClearDepth(1F);
GL11.glEnable(GL11.GL_DEPTH_TEST);
GL11.glDepthFunc(GL11.GL_LEQUAL);
GL11.glHint(GL11.GL_PERSPECTIVE_CORRECTION_HINT, GL11.GL_NICEST);
GL11.glCullFace(GL11.GL_BACK);
GL11.glEnable(GL11.GL_CULL_FACE);

解决方案

Make sure GL_TEXTURE_WRAP_S and GL_TEXTURE_WRAP_T are set to GL_CLAMP_TO_EDGE.
