Opengl linear depth
Web在Qt中使用OpenGL需要使用QOpenGLWidget类,该类继承自QWidget类,可以在其上绘制OpenGL场景。首先需要在Qt项目中添加OpenGL模块,然后在QOpenGLWidget的构造函数中设置OpenGL版本和渲染器,接着在paintGL()函数中编写OpenGL代码,最后在resizeGL()函数中设置OpenGL视口大小。 Web12 de jan. de 2008 · GL_LINEAR “converts” the depth texture down to 8bit when doing depth buffer lookups. if you don’t want to use glCopyTex (Sub)Image2D, like I said, use the 2nd method I described. glBindFramebufferEXT (GL_FRAMEBUFFER_EXT,0); glBindTexture (GL_TEXTURE_2D, depthTextureID); drawNiceTexturedQuad ();
