support online rendering #37

Closed xiaotaw closed 4 years ago

xiaotaw commented 4 years ago

Hi, I noticed surfelwarp support offline rendering. It's very cool to display rendered images (e.g. live_abedo.png) on screen, instead of saving into local files.

Simply comment out glfwWindowHint(GLFW_VISIBLE, GL_FALSE);, it just displays a black window. HAHA

Thank you!

You need to delete the glBindFramebuffer in the drawing function. Here is a tutorial: https://learnopengl.com/Advanced-OpenGL/Framebuffers

Done, Thx!

Hello, could you tell me which glBindFramebuffer should I delete? @xiaotaw

Always set the second parameter to be 0, and the pics/images will be updated in windows. glBindFramebuffer(GL_FRAMEBUFFER, 0);

Note: Based on the current code, you also have to set 'offline rendering' with True.

Thanks, i tried but still failed. Maybe I should look through the whole project.

@daxiong-123 try one more time? it should work:

  1. comment out glfwWindowHint(GLFW_VISIBLE, GL_FALSE) to make sure the blank window appears
  2. find function drawVisualizationMap in file RendererDraw.cpp, and modify glBindFramebuffer ( line 191)
  3. in the same function drawVisualizationMap, insert glfwSwapBuffers(mGLFWwindow); before cleanup code (line 218).
