I'm trying to get a part of the world and display it with a framebuffer.

The current code that I tried uses the default Minecraft Framebuffer class, and the code looks like this

Framebuffer framebuf = new Framebuffer(Display.getDisplayMode().getWidth(), Display.getDisplayMode().getHeight(), true);
framebuf.framebufferRender(128, 128);
framebuf.deleteFramebuffer();

The old code looks like this
glBindFramebuffer(GL_FRAMEBUFFER, fboID);
// Init ColorTex
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, colorTexID);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA8, Display.getDisplayMode().getWidth(), Display.getDisplayMode().getHeight(), 0, GL_RGBA, GL_INT, (ByteBuffer) null);
glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, colorTexID, 0);
// Init Depth
glBindRenderbuffer(GL_RENDERBUFFER, depthRenderID);
glRenderbufferStorage(GL_RENDERBUFFER, GL14.GL_DEPTH_COMPONENT24, Display.getDisplayMode().getWidth(), Display.getDisplayMode().getHeight());
glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, depthRenderID);
// Set FBO pos
glClearColor(0.1f, 0.0f, 1.0f, 1.0f);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glBindTexture(GL_TEXTURE_2D, 0);
glViewport(0, 0, 640, 480);
glOrtho(0, Display.getDisplayMode().getWidth(), 0, Display.getDisplayMode().getHeight(), -1, 1);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glTranslated(x, y, z + 5.0);
glRotated(rotX, 0.0, 1.0, 0.0);
glRotated(rotY, 1.0, 0.0, 0.0);
glBindFramebuffer(GL_FRAMEBUFFER, 0);
// Render FBO
glBindTexture(GL_TEXTURE_2D, colorTexID);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glTranslated(0, 0, 0);
glBegin(GL_QUADS);
glTexCoord2f(0.0f, 0.0f);
glVertex3f(0.0f, 0.0f, 0.0f);
glTexCoord2f(1.0f, 0.0f);
glVertex3f(1.0f, 0.0f, 0.0f);
glTexCoord2f(1.0f, 1.0f);
glVertex3f(1.0f, 1.0f, 0.0f);
glTexCoord2f(0.0f, 1.0f);
glVertex3f(0.0f, 1.0f, 0.0f);
glEnd();
glDeleteFramebuffers(fboID);
glDeleteRenderbuffers(depthRenderID);
glDeleteTextures(colorTexID);

Both snippets wield the exact same results, nothing displays at all, but there are no errors. So I'm wondering how I can get it to render.

Thanks in advance!
